Tomatoes grow in all Sunset Climate Zones as an annual. They need temperatures in the range of 55 to 100 degrees Fahrenheit and 8 hours of sunlight daily. Each tomato plant should produce 10 to 15 pounds of fruit when grown properly. Even though these plants are heavy feeders, they can be fed natural products to help fruit production. Yellowing leaves and stunted growth indicates a tomato plant needs a boost of nutrients.
Spread 3 to 4 inches of well-rotted compost over the tomato planting area. Dig the compost into the top 12 inches of soil with a shovel and break up the dirt clumps to obtain a smooth-textured soil. Adding compost to the soil increases air, water and nutrients available to the roots of the tomato plants, encouraging strong plant growth.
Plant the tomato plants in the amended soil. Spread a 3 to 4-inch layer of organic mulch, such as dried leaves or grass clippings, around the base of the plants. Mulching reduces soil moisture loss, regulates soil temperatures, discourages weed growth and provides a source of slow-release nutrients.
Clean a large container and fill it with water. Take a large cloth bag and fill it with organic materials like seaweed, garden plant debris and kitchen scraps. Tie the bag shut, attach it to a broom handle or a long stick and place the bag in the water with the stick across the top of the container; this allows you to retrieve the bag without reaching into the water you are using to create organic tea.
Check the organic tea every couple of days to see if it has turned a dark brown color. Once finished, remove the bag and empty the contents into the compost pile. Dilute the organic tea by mixing 1 cup of organic tea with enough water to make it look like weak tea. Drench the root zone of the tomato plants with the organic tea when the first small tomato has appeared.
Coffee has a myriad of uses besides just being a beverage. Many people use it for mulching and gardening as it contains minerals and nutrients that are beneficial to soil and plants. Tomatoes are one vegetable plant that does very well with used coffee grounds. Coffee grounds provide acid and nitrogen, nutrients that fertilize and condition the soil, providing ideal conditions for growing tomato plants.
Before tossing coffee grounds in the garbage, think twice. High in nitrogen, they can have a second life as a natural fertilizer and pest deterrent and are ideal for use in growing tomatoes. Non-coffee drinkers can also fertilize with grounds, because many coffee shops give away used grounds for free to anyone who asks. Depending on the intended result, coffee grounds can be scattered around the base of tomato plants or used in compost for them.
Using coffee grounds Begin by saving used coffee grounds. Sprinkle the coffee grounds on top of the soil surrounding the plant. Water the grounds daily to maintain proper moisture and to encourage the nutrients in the coffee grounds to equally distribute in the soil. Reapply the coffee grounds when you have a difficult time noticing their presence on top of the soil.
Fertilizer Purchase a 5-gallon bucket from the local hardware or gardening store. Place ½ pound of ground coffee in the bottom of the bucket. Boil a medium sized pot of water and add to the ground coffee. Let it steep for 5 minutes and then fill the remaining space of the bucket with water from the outdoor hose. Place the coffee solution in a watering can and apply to your tomato plants on a daily basis until you achieve the desired result.
Coffee as a natural insecticide Coffee grounds also act as a natural insecticide on tomato plants, according to information from Scribd.com. Use this method especially if growing organic tomato plants, as this removes the need for a synthetic insecticide. Prepare coffee in a French press as double strength. Add 6 tbsp. of ground coffee to a 16-ounce French press and fill with boiling water. Let steep for 4 minutes and then stir with a spoon. Let the coffee cool to room temperature before using on a plant. Use this extra strength coffee on your tomato plants by slowly pouring the coffee, including the grounds, over the leaves and fruit of the tomato.
Coffee grounds and tomato growth Using coffee grounds to grow healthy tomatoes is a smart idea for several reasons. Coffee grounds are a strong source of nitrogen, which is vital to the development of healthy roots and aids in the development of plant tissue and the production of chlorophyll. Coffee grounds are also an easy means of enriching soil with organic matter, which improves aeration, drainage and water retention.
Composting Mixing coffee grounds with wood ash, shredded leaves and lime creates a rich compost, one high in nitrogen that's easy for tomatoes to access. Using grounds to make compost is also a way of lessening their acidity, because in their raw, untreated form, coffee grounds may make the soil too acidic for plants to thrive. No Matches Found.

Protection A bag of used coffee grounds serves double duty as an all-natural fertilizer and slug and snail repellent. The caffeine in coffee grounds is lethal to snails and slugs, which absorb it when crawling over the grounds using their soft, fleshy foot. To use coffee grounds for this purpose, simply pour them around tomato plants, encircling them completely to create a poisonous barrier for unwanted guests.
Other benefits Coffee grounds also attract beneficial creatures to garden beds. Earthworms love coffee grounds and serve many purposes in the garden, turning organic matter into plant food and increasing the amount of oxygen and water in the soil. Coffee grounds also fight late blight, a fungal disease that covers tomato plants in lesions before destroying the fruits. The disease is typically controlled with fungicides, but coffee grounds are a nontoxic, natural alternative.
Tomatoes are America's most popular garden vegetables. They are easily cultivated in the warm months of summer and produce a healthy crop of fruit in small home garden spaces. Tomatoes need at least 6 to 8 hours of daily sun to flourish. You can support the optimum health and fruit production of your tomato plants by growing them in fertile, well-drained soil and by fertilizing them with organic or synthetic agents that offer the nutrients they crave.
Fertilizers can be a critical part of any successful gardening project. In the case of growing food plants such as tomatoes, careful selection and addition of fertilizer to the soil in which you are growing tomatoes can yield larger tomatoes as well as more substantial harvests. Luckily, with some careful consideration, you can choose the right fertilizer and know how to best incorporate it into your soil.
Test your soil Good tomatoes grow in good soil. They develop the best root systems in deep, organically rich soil that remains consistently moist without becoming boggy. Tomatoes prefer a slightly acidic soil environment with a soil pH of 6.5 to 6.8. Before planting tomatoes, test your soil using a complete kit from a local garden center or service available in your area. Select a report that details primary nutrients -- nitrogen, phosphorus and potassium, as well as secondary plant nutrients including calcium and magnesium. Select one that also includes an assessment of organic matter content and soil texture.
Improve your soil Adjust acidic soils with lime products and alkaline ones with sulfur supplements, according to your soil report. Dry, sandy soils and dense clay types benefit from the incorporation of organic materials such as finished compost, aged manure and chopped pine bark. These amendments facilitate better soil moisture balance, act as pH buffers and offer essential primary and secondary plant nutrients to tomato roots. Before planting, apply a 3- to 4-inch layer of these materials to your planned garden area. Work or till this in to a depth of 12 to 18 inches, along with your native soil.
Elemental nutrition Tomatoes, like all vegetable crops, require certain levels of easily accessible nutrition. Scholarly studies have shown that tomatoes taste better when they receive extra potassium and phosphorus while growing. You will get higher yields of disease-free fruits when easily available calcium and magnesium are present to help prevent blossom-end rot, a common bane of tomato growers. If these nutrients are imbalanced, according to your soil report, you can supplement your soil with organic or synthetic fertilizers that provide them.
Fertilizer choices Natural plant nutrient sources you can use include meals of bone, blood, alfalfa and fish. Specialty organic products, designed specifically for tomatoes are also available. These contain balanced levels of nitrogen, phosphorus and potassium as well as important secondary nutrients like calcium and magnesium. They also enrich the soil with humic matter as they break down over time. Synthetic fertilizers with a low nitrogen, high phosphorus and high potassium balance, particularly 8-32-16 or 6-24-24, are recommended for productive tomato plants.
Fertilizer ratings To understand how to choose a fertilizer for tomatoes or for any other plant, it is necessary to first understand how fertilizers are differentiated from each other. Any fertilizer you purchase will have three numbers printed conspicuously on the bag; these numbers are known as the NPK rating, because they describe the concentration, by weight, of nitrogen (N), phosphorus (P) and potassium (K). For instance, if a fertilizer is labeled as 5-10-15, it contains 5 percent nitrogen, 10 percent phosphorus and 15 percent potassium by weight, with other ingredients making up the remaining 70 percent of bag weight.
Fertilizer selection To a substantial extent, the choice of what type of fertilizer is dependent on the unique nutritional needs of the soil in which the tomatoes are growing. Have your soil tested by a local university extension office and see what nutrients your soil is lacking the most. In general, however, tomatoes respond well to fertilizers with a low concentration of nitrogen and higher concentrations of phosphorus and potassium, such as 8-32-16 or 6-24-24. Avoid using ammonia fertilizers such as urea or ammonium nitrate for your tomato plants.
Application tips A fertilizer fitting this description should be worked into soil just before planting time. Use around 1 lb. of fertilizer per 100 square feet of garden space, unless you are only able to find a 5-10-5 or 5-10-10 fertilizer, in which case you should increase the amount used to 2 lbs. per 100 square feet to provide soil with enough nitrogen content.
Other considerations The above guidelines describe how to prepare your soil for successful tomato plants, but to fully maximize your fruit yield, additional fertilizer applications are necessary. A solution consisting of 2 tbsp. of 10-52-17 or 15-30-15 fertilizer in one gallon of water should be added to the planting hole when tomatoes are transplanted to outside soil. Finally, side-dress the tomato plants with calcium nitrate at a rate of 3.5 lbs. per 100 square feet to ensure that plant nutrients are not diverted from fruit production into leaf production.
Pecans are one of the few truly all American foods. Pecan, so named in the Algonquin Indian language because it was a nut that was so hard it required a stone to crack, is native to North America. Settlers ate wild pecans, and today ~90% of all pecans are grown in the U.S. In the author's opinion, pecan pie, not apple pie, should be considered the quintessential American desert (as apples are originally from central Asia).
Pecan trees can grow in USDA zones 5-9, but generally do better in the southern states. Pecan trees generally grow between 70-100 feet tall, but have grown taller. They have a moderate growth rate once established, but are very slow to establish without help due to their root structure.
For those seeking to plant pecans mainly as a landscape tree, as always the Arbor Day Foundation is an excellent source of bare root trees. For those looking to plant pecan trees for nut production, however, grafted trees are strongly recommended. Grafted trees start nut production earlier and enable more reliable nut production.
New Mexico State University provides excellent information about buying grafted pecan trees. They recommend root stock 3-4 years old and scion wood 1-2 years old, with a diameter (caliper) of 5/8 - 1 inch.
Pecan trees can be very difficult to establish, especially in the dry Southwest states. Pecan trees have a true tap root initially, meaning they have one central root that grows straight down. This is similar to many other nut trees and allows the trees to access deep soil capillary water during periods of drought. However, it also makes the pecan trees very difficult to establish. The roots need to be kept almost constantly wet until they establish lateral roots, and this can entail a huge water bill, many times the initial cost of the tree, not to mention the cost of the labor to install irrigation or move hoses between the bases of trees at least once weekly. Is there a solution that eliminates the need for irrigation of the newly planted pecan? Yes - and it is called the Groasis Waterboxx.
The Groasis Waterboxx is a self refilling water battery, and plant incubator which is placed around the newly planted pecan (or any other tree). It is filled with 4 gallons of water, and the soil beneath the Waterboxx is saturated with up to 10 gallons of water. The Waterboxx has a wick which allows water to be slowly released to the growing tap root of the pecan. The Waterboxx is refilled from dew and rain. The Waterboxx, although 10 inches high, can be completely refilled with 4 inches of rain. With proper set up, the Waterboxx achieves water homeostasis, meaning it will not run dry even without refilling. This is because it is able to fill with condensation most nights and utilize and store rarer rains.
The Waterboxx also prevents the soil beneath it from drying out (its UV resistant plastic is impermeable to water). This both sustains the tap root of the pecan and induces it to grow to deep capillary water quickly. The Waterboxx can be left around the base of the pecan tree until the caliper (diameter) of the trunk reaches almost 3 inches. The mechanism of the Waterboxx is explained clearly below.
Of note the Waterboxx has been used for many other trees, including red oak, Giant Sequoia, pear and other fruit trees. It can also be used for annual garden plants like pumpkins.
Be the first in your area to start growing pecans with the Groasis Waterboxx. Buy the Groasis Waterboxx here (from Dew Harvest). Pecan trees grown for nut production can be purchased from Stark Brothers Nursery. We would love to hear your comments below - to leave one, please click on "Comments".
Tomatoes are one of the few garden vegetables that can land their caretakers in a world of despair when problems erupt -- for all their trouble, it's a wonder anyone grows them. When tomatoes develop yellow leaves, it's unlikely to be caused by too much fertilizer, but could be due to other environmental problems or diseases.
Fertilizer is a useful product for plants such as tomatoes. The plants use the fertilizer as food to grow large and healthy. But, any gardener who has ever thought, "if a little bit is good, a lot will be better" in regards to fertilizer, soon finds out the hard way that the opposite is true. Too much fertilizer can burn the roots of plants, and can cause wilting, yellowing and even death.
Fertilizing tomatoes A home soil test kit will give you valuable information about your tomato patch. Tomatoes thrive with medium fertility and show problems when fertility is too high or too low. Usually, they don't require any feeding at planting time, unlike many vegetables. Successful tomato producers may wait to feed tomato plants until fruits are about the size of table tennis balls. At this point, side-dress tomatoes with a small amount of nitrogen fertilizer every four to six weeks until the final harvest. Signs of too much fertilizer Over-fertilizing tomatoes early in their lives results in plants that are tall and spindly, with lots of deep green foliage, but few flowers. Tomatoes can't simply use the ideal amount of nitrogen they need to thrive. Instead, excess nitrogen in a tomato plant tells the plant to produce more leaves and stems at the expense of blossoms and fruits. Sometimes, excess nitrogen can be leached from the root area of tomato plants by repeated, deep waterings.
Causes of yellowing leaves Common causes of yellow leaves on tomatoes include cool soil, age-related death of the lower leaves and a myriad of nutritional deficiencies including nitrogen, boron, potassium, iron and magnesium. Leaves may also yellow when affected by fusarium wilt, bacterial wilt or verticillium wilt. These disease are the result of fungal or bacterial pathogens multiplying rapidly in vascular tissues, causing the plant to die from lack of nutrients. Root knot nematodes can kill plants in a similar fashion, but the roots will bear distinctive swollen knots. Wilts and nematodes are difficult or impossible to treat once plants are severely affected.
Fertilizer burn The damage done by over fertilizing plants is known as fertilizer burn. This is because plants that are given too much fertilizer have a burned appearance, with foliage that turns brown and crispy. Fertilizer burn occurs when the chemicals in fertilizer draw water out of the plant. As a result, the plant dries out. This process is known as a hygroscopic process. Salt in fertilizers are the frequent cause of the fertilizer burn.
Symptoms Over fertilized tomato plants first show signs of damage in their leaves. As water withdraws from the leaves, they appear limp and begin to yellow. As the symptoms progress, the yellow leaves turn brown and become crispy. The best way to check for fertilizer burn around a tomato is to take a sample of the soil from around the plant and submit it for analysis to a soil laboratory. The soil laboratory will inform you if there is a high level of nutrients in the soil.
Problems from lack of fertilizer Despite the dangers of fertilizer burn, most tomatoes are heavy feeders. Without fertilizer, tomatoes may suffer from blossom end rot, a condition that occurs when there is not enough calcium in the soil. Blossom end rot appears on tomatoes first as a slightly brown, water-soaked lesion on the blossom end of the tomato. The lesion eventually enlarges and turns black and leathery.
Soil solarization Although the disease and pest causes of yellow leaves on a tomato are difficult to cure once the plant is already showing symptoms, you can use soil solarization to destroy these organisms before you plant your next tomato crop. After the troubled tomatoes have died or are removed, till the garden well and smooth the soil with a rake. Apply a 1 mil clear plastic tarp over the prepared and watered soil and leave it there for six weeks. This heats the soil to high enough temperatures to destroy many nematodes and soil-borne fungi and bacteria before the upcoming growing season.
Tomatoes (Lycopersicon esculentum) like it hot -- but not too hot. The plants don't flourish until the daytime soil temperature is between 70 and 80 degrees Fahrenheit. But growth slows and fruit won't set above 90 F. Fertilizing in the heat can force more leafy growth than the roots can support. As well, water-soluble fertilizer applied to the potting mix, or in the water -- which container tomatoes need a lot of in the heat -- can burn the leaves since it moves quickly from roots to leaves as the plant tries to cool itself through transpiration. To avoid these problems, don't fertilize a potted tomato when its soil temperature is above 85 F (30 C).
Cool containers When your tomatoes live in pots, the temperature in the root zone can be higher than the ground, and even the air temperature. Water potted tomatoes deeply whenever the top 1/2 inch of soil is dry -- with no water-soluble fertilizer mixed in -- to help the plant moderate its own temperature. Mulch, a light-colored pot -- or wrapping the pot in a light-colored or reflective material -- and a pot with heavy, insulating walls can help a potted tomato's soil stay cool so water-soluble fertilizer is effective. Once the temperature is back below 85 F, apply 1 tablespoon of a 5-10-5 fertilizer per gallon of water every 10 days while fruit is setting.
Water-soluble fertilizers are formulas that are dissolved in water and applied to plants at the base or foliage throughout the growing season. They’re ideal for tomato plants, which have low nitrogen requirements, because they’re fast acting, giving your plants the nutrients they need almost immediately. Water-soluble fertilizers can also be applied more frequently than granular fertilizers.
Producing bumper tomato crop may be a well-guarded secret, but many gardeners agree it begins with water-soluble fertilizer. Water-soluble fertilizer is mixed with water and applied directly to the plants throughout the growing season.
Selecting the right formula Using a fertilizer that is high in nitrogen will give you a lush, green plant, but not much fruit. Tomato plants require a low nitrogen, high phosphorus, and medium to high potassium content. A water-soluble fertilizer with nitrogen, phosphorous, potassium ratio of 8-32-16 or 6-24-24 is often ideal. Always check the label when selecting a water-soluble fertilizer. Some formulas intended for use with tomatoes will contain traces of other elements, which can change the ratio slightly. Avoid using any fertilizers containing urea or ammonium nitrate for tomato fertilization.
Application A base application of water-soluble fertilizer provides your tomato plant food as you water it. Follow the mixing instructions on the fertilizer label and then apply it to the soil at the plant’s base with a watering can. The nutrients are released with the water. A foliar application can also be used when your tomato needs trace elements such as iron immediately. Mix the fertilizer according to the label directions, and then apply it directly to the leaves instead of the soil. Whichever way you apply the fertilizer, keep in mind young plants only require about a cup of water-soluble fertilizer weekly. This rate is increased as the plant matures. Established tomato plants can be fed with up to a gallon of water-soluble fertilizer at each application.
Timing The timing of application depends on the water-soluble formula you use. In general, most formulas require application every seven to 14 days, but you can mix the fertilizer at half or quarter strength and apply it more frequently. This may be necessary for new or transplanted tomato plants, which may require one to three applications of water-soluble fertilizer at the base of the plant to avoid transplant shock. When used as a starter solution, water-soluble fertilizer should have a high phosphorous content, but a low nitrogen and potassium content. Water-soluble fertilizers applied every two to four weeks during the summer help ensure nitrogen stress doesn’t affect your tomato plants. When grown in soils that are low in organic matter, your tomato plants will have little to no nitrogen around midsummer. If the foliage is yellowing, this is a sign that the plants need nitrogen.
Mixing precautions Read the label instructions before mixing any water-soluble fertilizer, and always follow the manufacturer’s recommendations. If you mix the solution so that the concentration of fertilizer is too high, the nutrients will be highly concentrated and this can damage your tomato plant. If you mix the fertilizer in a tank prior to application, use all of the solution before you mix a fresh batch. Never try to mix more into an existing solution because you may increase the fertilizer’s concentration. When using a dry formula, do not apply it to your plants until the crystals or powder have fully dissolved in the water. Check the solution periodically to ensure that settling has not occurred. Settling of undissolved fertilizer can result in an uneven application, and this can lead to stunted growth or plant death.
Considerations
Formula Fertilizer high in nitrogen produces lush green foliage with few tomatoes and should be avoided, unless a soil test determines that nitrogen is needed. According to the University of Missouri, tomatoes require fertilizer low in nitrogen, high in phosphorus and medium to high in potassium. A formula of 8-32-16 or 6-24-24 is ideal. However, formulas for water-soluble fertilizer designed for tomatoes may include other trace elements and the ratio may differ.
Foliar feeding Water-soluble fertilizer designed for tomatoes is available under several brand names in a garden supply store. These are designed to be mixed with water (follow the instructions on the specific brand you purchase) and applied to the tomato plants, wetting the foliage. The foliage absorbs nutrients directly through the surface of the leaves giving the plant a quick burst of nutrients. Excess fertilizer drains into the soil providing nutrients to the roots.
Application Typically applied with a foliar feeder attachment to the hose, the amount of dry mixture is measured and added to the feeder attachment. As water is forced through the feeder, the appropriate amount of fertilizer is mixed with the water, creating liquid fertilizer for watering the garden. Water-soluble fertilizer can also be mixed in a bucket and applied by hand or with a sprinkling can. Begin by providing a cup of water-soluble fertilizer to young seedlings and gradually increase the amount as the plant matures. Mature tomato plants may require up to a gallon of water-soluble fertilizer with each application.
Timing Timing of application depends on the specific formula you purchase, but typically ranges from every seven to 14 days. Check the container for the manufacturer's recommendations. Some gardeners prefer to mix the formula to one-half or one-quarter strength and apply it more frequently. For newly planted tomato plants, or those grown in containers on the deck or patio, this may be a good option -- but do not exceed the recommended amount. This is one case where more is not better and may harm sensitive roots or damage foliage.
