Receiving adequate nutrients to your vegetable garden plants is one of the key elements to producing high-quality produce, including building soil with various materials and fertilizers.
Vegetable gardens benefit from receiving an all-purpose or high nitrogen (N) fertilizer at the time of transplanting or shortly thereafter when their plant has reached a few inches tall. Certain vegetables may also require soil amendments or supplemented fertilizer treatments later in the season for optimal performance.
Spring
Now is the time to get your garden growing again by applying fertilizer! Start by reading and following the label instructions of any granular or liquid fertilizer you select; they should offer guidance regarding optimal rates, application times and formulas for specific plant types. Doing this will prevent overdosing that could damage young vegetables and edible crops that need light touch fertilizers.
Next, decide on an application equipment system for use. Granular fertilizers can be broadcasted and raked into place while liquid fertilizer must be diluted according to package directions before being applied over soil. A handheld spreader can make the job faster while guaranteeing even coverage throughout your vegetable gardens. Most liquid fertilizers also come equipped with hose attachments for easier spraying, saving even more time during application and making application even more efficient.
When choosing a fertilizer for your garden, choose one made from granular materials and designed for vegetables or edible crops. Liquid fertilizers may cause root burn or damage and should only be used as supplemental feeds throughout the season. A great natural soil amendment and source of rich organic material, worm castings are great additions that help improve soil composition – look for one such as Foxfarm Happy Frog Tomato and Vegetable Fertilizer which offers four or 50-pound bags as well as concentrated liquid solutions.
Mulch will increase the effectiveness of any slow-release fertilizers you pre-plant in your vegetable gardens and flower beds. Mulch helps maintain cool and damp conditions underfoot, which enhances their effectiveness. Also be sure to sweep up any fertilizer accidentally spilled onto hard surfaces, such as driveways or sidewalks, so it does not wash into storm drains and pollute local bodies of water. Finally, if rain is forecast within 24 hours it would be wiser not to apply granular fertilizer, as rain would wash its nutrients into the ground rather than leaching into local water bodies.
Summer
Have you ever noticed how lush, bright green vegetables in your neighbor’s garden look so healthy and delicious-looking? Their stunning array of vibrant veggies is likely due to regular fertilization efforts.
Dependent upon your hardiness zone and type of vegetables you’re planting, when and which types of fertilizers to use can make an enormous impact on the success of your vegetable garden. First things first – get a soil test conducted so you know which nutrients exist in your soil as well as the optimal doses to add.
Most vegetable plants are heavy feeders that deplete nutrients from the soil quickly, so regular fertilization is necessary if you want your crops to reach maturity and provide maximum nutrition. Without fertilization, vegetables may grow more slowly or not be as nutritionally dense.
Fertilizer is a combination of nitrogen, phosphorus and potassium essential for plant growth. There are various kinds of fertilizers to choose from; which one best suits your garden depends on factors like its soil type, the amount of sunlight it receives and any unique needs from specific plants.
Before planting vegetables, fertilizer application is key. Mix it into the garden bed or apply around seedlings/transplants; or granular fertilizers can still be mixed into top 2-4 inches of soil using watering techniques – however be wary not to overfertilize as that could result in nutrient imbalances, burnt foliage and an abundance of salt in your soil that reduces its water absorption abilities.
Once soil temperatures heat up in summer, you can also utilize liquid or soluble fertilizers to feed your veggies. Make sure you follow UF/IFAS recommendations regarding rates, application timing and formulas when fertilizer applications occur; rain can easily wash them away off hard surfaces into storm drains and local water bodies contributing to water pollution. If there is an imbalance among nutrients such as yellow leaves, leggy stems or weak, unproductive growth patterns indicating an issue, stop applying fertilizer immediately and test soil again before continuing.
Fall
In order to thrive, vegetables need a lot more than just sunlight and water. They also need a steady supply of nutrients, especially nitrogen. When plants in nature are growing in the wild, they can often find the nutrients they need in organic material that has been broken down by other plants and bacteria in the soil around them. But, when we plant our own vegetable gardens, it is up to us to make sure our crops get the nutrients they need to grow big and healthy.
A good way to do this is by using fertilizer. But before you run out to the store and grab any old fertilizer, it is best to have your soil tested first. You can do this at home with a simple kit or send a sample to your local Cooperative Extension office for more accurate results. A professional soil test will tell you exactly what nutrient is needed, when it is needed, and in what amount.
After the garden has been planted, it is a good idea to apply a granular organic fertilizer that contains a combination of nitrogen, phosphorous, and potassium, as well as other micronutrients. This type of fertilizer is slow to release its nutrients, allowing your vegetable plants to absorb them at a rate that is more in line with their growth rates. This helps to prevent over-fertilization and nutrient loss over time.
Some plants like corn require more frequent feedings than others, such as leafy greens or tomatoes. To keep your corn on track for a good harvest, you can give it a larger application of fertilizer in the fall right before it goes into its vigorous summertime growth spurt. This will help ensure your corn has the nutrition it needs to thrive and produce lots of tasty, nutritious kernels.
If you are worried about the environmental impact of applying too many fertilizers, try to limit your use of chemical fertilizers as much as possible. You can also avoid water pollution by limiting the amount of fertilizer you use on hard surfaces, like your driveway, and by not fertilizing before a rain shower is expected. If you do apply fertilizer, sweep up any that spills onto a hard surface and dispose of it appropriately so it does not wash into storm drains and into nearby water bodies.
Winter
Most people believe that vegetables remain dormant during winter and cannot grow, yet many vegetables thrive during this season. Vegetables have proven tough enough to withstand temperatures down to below freezing, rainfall or snow and darkness with ease – but don’t assume that fertilizer won’t play a crucial role.
Vegetable garden fertilization in autumn is highly recommended because it gives plants time to take in nutrients before their dormant period starts. Application timing will depend on your US hardiness zone and weather patterns – ideal timing would be when the ground temperature is still warm but will become frost-bitten within weeks, according to Burpee.
Organic mulch or compost can also add many advantages to the soil, and should be integrated before planting or carefully spread around existing vegetables, according to Zettl. The goal should be to boost existing growth without stimulating new shoots that could be affected by cold or frost conditions.
If you haven’t conducted a soil test yet, now would be an excellent time. Testing will give you an understanding of your soil’s pH levels and whether they need boosting or lowering. This will give you a clear idea of which fertilizers you need and when.
The type of fertilizer used depends on what you’re growing and your gardening style. For instance, leafy vegetables like kale and chard require nitrogen while root crops like carrots and potatoes need phosphorus and potassium fertilizers.
Organic manure such as chicken, cow and horse manures can provide essential plant nutrition. However, fresh manure could potentially harm plants. As an alternative option, commercial fertilizers with balanced NPK ratios – where numbers represent nitrogen, phosphorus and potassium content in one product – could provide just what’s needed. Simply work the granular feed into the soil at three to five inch depth, possibly adding mulch as an additional barrier against leaching of fertilizer into waterways or streams.
