Vegetable plants are prolific soil depleters that require regular fertilization in order to remain healthy and productive.
Fertilizer applications should take place prior to or during planting, followed by additional side dressings throughout the growing season. Liquid fertilizers can be applied via hose-end attachment or simply poured directly over leaves.
Spring
Fertilizing a vegetable garden is essential to encouraging healthy growth and increasing yield, but too much fertilizer can damage soil structure and make it harder for plants to absorb nutrients. Knowing when and how much fertilizer should be applied will help avoid these potential issues.
Fertilize a vegetable garden before planting for optimal results; this allows nutrients to absorb into young roots and be readily available as the crop matures. However, you can still give them some TLC by slowly working granular fertilizer into soil surrounding plants; only work the granules into top 3-4 inches for best results – then water it thoroughly so it saturates completely into soil.
Organic or natural vegetable fertilizers should be chosen, as these help improve soil structure while creating an ideal environment for microorganisms that contribute to plant health and development. Natural sources include manure, animal or fish meal, peat compost and other organic materials derived from nature while synthetic or inorganic fertilizers tend to contain targeted amounts of nutrients that plants easily absorb into their systems.
Different crops need different levels of nutrition, so when fertilizing, take into account soil test results and the individual needs of your vegetables. Leafy greens for instance require lots of nitrogen for leaf growth while fruits and beans require phosphorus for flowering and fruiting purposes. When using soluble fertilizers, follow label instructions regarding how much to apply per application.
As with other fertilizers, granular vegetable fertilizer should be worked into the soil prior to an expected heavy downpour. Applying this type of granular fertilizer prior to transplanting seedlings or sowing seeds ensures they will become part of their growing environment more easily. Once weather is warm enough for growth to commence and seeds sprouting occurs regularly throughout summer, switch over to using liquid fertilizers instead for ongoing application.
Summer
Most vegetables flourish best when their soil is regularly fertilized – whether your garden is in the ground or container garden. Fertilization’s timing can make or break your plants’ success or failure.
Fertilizer should be applied prior to planting in the spring and at regular intervals throughout the growing season; when, and which type, will depend on what kind of vegetables are being grown.
Floral veggies like tomatoes, peppers, peas and squash require fertilizers with high levels of phosphorous to promote blooming and fruit production. To get these essential nutrients into the ground, try applying liquid plant spike or granular fertilizer designed specifically for vegetables before the sun becomes too intense in the morning hours.
If you’re growing leafy greens or non-blooming vegetables, using a fertilizer with higher nitrogen (N) content is best. Look for one with the first number on its label being higher such as water-soluble powder or slow release granular fertilizers with increased N content. Apply as side dressing around plant bases or mix it with water for liquid spray feedings until plants start drooping; just don’t overdo it or you risk burning their roots!
Even with rich, fertile soil, your vegetable plants require additional fertilization on a regular basis in order to thrive and produce maximum yields. Doing this will allow them to flourish and give you optimal harvest results.
Once your vegetables are ready to harvest, stop fertilizing. As soon as they begin producing food, your plant uses up all available nutrients in making more leaves; thus decreasing food output; so stop fertilizing when multiple flowers or fruit sets emerge.
If you’re planning to replant your vegetable garden this autumn, make sure you conduct a soil test first. By doing so, you can improve the soil if necessary by raising pH with lime or lowering it with iron sulfate; that way when fertilization arrives in November, everything will already be perfect!
Fall
Fertilizers provide plants with essential nutrients they require for healthy growth and performance, so using fertilizers correctly is key for creating a nutrient-rich vegetable garden.
Fertilizing your garden prior to planting is the optimal strategy, as this ensures its nutrients reach young vegetables as soon as they begin their journey toward growth. Once planted, most vegetables require additional feedings throughout summer in order to remain healthy and produce their maximum output.
When adding fertilizers, be sure to read and follow any directions carefully. There are different types of fertilizers available, including granular and liquid. Granular varieties feature small pellets which are spread on top of soil before being worked in with tools – these granular fertilizers work great on herbs, leafy greens, root crops and fruiting vegetables! Most also contain essential nutrients like nitrogen, phosphorus and potassium which provide essential growth support.
Liquid fertilizers can be mixed with water and applied directly to soil or plant leaves using a sprayer or hose attachment. Liquid fertilizers may be applied as frequently as once weekly; however, two to six weeks between applications is usually optimal.
As it’s essential to your vegetable garden’s success, knowing when and why to stop fertilizing it is key as well. Once a crop has reached full production in mid-summer, additional fertilizers may only serve to increase foliage rather than fruit or veggies you are after; this could reduce yields as well as quality.
Whenever you have any inquiries about fertilizers and which would work best in your vegetable garden, speaking to a knowledgeable staff member of your local garden center may help. They can assist in selecting an ideal type of fertilizer and when to apply it. Also make sure your hands and tools remain clean when handling fertilizers! If any gets dropped accidentally onto hard surfaces like sidewalks or driveways, make sure it gets collected and properly disposed of – otherwise it could end up washing away into storm drains and pollute nearby water bodies.
Winter
Crops require the correct nutrients in order to thrive and produce delicious food, whether as seedlings or transplanted vegetables. Some organic matter may provide some of these essential elements; however, most vegetable and fruiting plants have special requirements that require regular fertilization in order to optimize production.
There are various kinds of plant food products on the market, from granular products that can be sprinkled or worked into the ground to liquid fertilizers that are applied with a hose or nozzle and sprayed onto leaves and soil, providing essential nitrogen, phosphorus and potassium (NPK) nutrients as well as micronutrients to ensure healthy vegetable and fruiting plants.
As a general guideline, plant food should be applied prior to planting season when weather temperatures are warming and soils become workable. This ensures that nutrients will be available immediately to new shoots when they emerge from the ground and before any potential frost arrives. However, if soil contains abundant organic matter without frost issues then one spring application should suffice in providing new plants a good start.
Fertilizers come in both natural forms like composted animal manure, as well as inorganic ones like nitrates and phosphates, or synthetic versions such as nitrogenous products like nitrates. Their choice typically depends upon what kind of vegetable or fruit garden you have as each crop requires different nutrient amounts for growth.
Most vegetables thrive with nitrate-rich fertilizer that provides plenty of nitrogen without burning plant roots when used at early stages. As they mature into producing their own fruits, however, switching to higher phosphorus feed can promote flowering and fruit ripening.
Some people use liquid plant food dissolved in irrigation water and sprayed on crops as regular maintenance products, however this practice should not be recommended as it can burn young roots and foliage of certain plants, potentially not being readily absorbed, and often leaching nutrients out of soil into waterways which could pose risks to wildlife and fish species.
