Apply fertilizer with caution, though: The only thing worse than starving a plant of nutrients is to accidentally overfertilize it.For edible crops, fertilizer is usually applied in the spring and mixed into the garden soil before planting.This ensures that there is less of a chance of the tender new growth brought about by the fertilizer getting immediately killed by frost.While a spring application is a good general rule, understand that what plants really need is help when they are growing the most.This occurs earlier for spring plantings of lettuce, arugula, kale , and other leafy greens .Tomatoes and potatoes will need extra fertilizer mid-season as the plants take up and use existing nutrients.Ornamental trees, shrubs, and perennials are often fertilized at the beginning of their growing season, as dormancy breaks.You do not want to add nutrients to your soil if it’s already available in high amounts; this may actually inhibit your plants’ growth.These three numbers refer to the three most important nutrients plants need: Nitrogen (N), Phosphorus (P), and Potassium (K).If you add up the numbers, they are the percentage of the bag’s total weight (the rest is simply filler to make it easy to apply).For tomatoes, we use a separate fertlize with a 3-4-6 ration which also contains calcium to help prevent blossom-end rot.Vegetable crops require most of their nitrogen after they have made considerable growth or have already begun to fruit.Later in the season, some plants benefit from a nitrogen side dressings (sprinkled in middle of rows).Sweet corn can benefit when plants are 8 to 10 inches tall and then one week after tassels appear.Spinach, kale, mustard, and turnip greens can benefit when plants are about one-third grown.These vegetables should NOT have added nitrogen: sweet potatoes, watermelons, carrots, beets, turnips, parsnips, lettuce.Processed fertilizers (also called “synthetic” or “chemical” fertilizers) are manufactured from natural ingredients such as phosphate rock (P) and sodium chloride (NaCl) and potassium chloride ( KC l) salts, but these are refined to be made more concentrated.Organic fertilizers are materials derived from plants that slowly release nutrients as the micro-organisms in the soil break down.(Plus, they don’t leach into and pollute waterways, as do many of the synthetic, water-soluble fertilizers, which plants can’t fully absorb.).While most organic fertilizers are slow-release products, some release a portion of their nutrients quickly (examples are animal manure, biosolids, and fish emulsion).During the growing season, lighter supplemental applications can be made to the top inch of soil in crop rows and perennial beds and around the drip lines of trees or shrubs.No matter how carefully you remove plants from their containers and place them in the ground, some root hairs will break.The fertilizer will reach the roots immediately and enter them at the broken points, potentially “burning” them and causing further die-back.If you have more questions about fertilizers, please ask below, or we encourage gardeners to call their country’s free cooperative extension office for local advice.Visit our complete Gardening for Everyone hub, where you’ll find a series of guides—all free! .

How to Fertilize Your Vegetable Garden With a Fertilizing Schedule

Nitrogen promotes leafy growth, which is why lawn fertilizers typically contain a larger percentage.Potassium encourages strong root development, while phosphorous helps flower and fruit production.Organic fertilizers, on the other hand, need soil bacteria and fungi to break them down into absorbable components.In short, fertilizer replenishes and supplements soil with the nutrients your vegetables need to grow healthy roots, foliage and fruits.Send a soil sample to your local extension office for the most accurate, reliable results.If you make an uneducated guess, you risk applying the wrong fertilizer, damaging your plants or spending money on products you don't need.According to the University of New Hampshire Cooperative Extension, the optimal soil pH for vegetables falls between 6.5 and 6.8.Once your results fall in the vegetable pH sweet spot, you'll be ready to get fertilizing and planting.Once your plants are in the ground, it's time to focus on providing optimal nutrition for the remainder of the growing season.You can either follow a standardized schedule or customize your plan to maximize your specific plants' growth.Consider the crops you are growing and mark some dates on your calendar to remind you when it's time to feed, Zettl suggests."For example, broccoli and cauliflower are notoriously hungry and will not form a crown if they aren't fed enough, whereas applying too much fertilizer to lettuce can cause leaves to become soft and more prone to rot.".For example, tomatoes consume large amounts of calcium and often need supplementation throughout the growing season.As the growing season progresses, look for signs your plants are weakening, such as drooping, wilting, stunted growth or a lack of fruiting.Zettl says, "Plants that require full sun need at least six hours of direct light daily.According to the University of Missouri Extension, some vegetables need a nitrogen boost through side-dressing as the growing season progresses.: After the first flowers emerge Sweet corn : When plants reach 8 to 10 inches tall, then again shortly after tassels appear. .

When & How To Fertilize Garden Plants

Tomatoes are heavy feeders, and need a steady supply of nutrients for maximum growth.But by simply applying the right kind of fertilizer, at the right intervals, plants can have the energy they need to grow strong and healthy.Young tender seedlings and transplants need time to adjust to the soil and outdoor life.Not only are they less likely to be able to soak up the nutrients, depending on the fertilizer and method used, the scorching sun can burn and injure plants.Instead, fertilize plants in the early morning or late evening to avoid any issues and maximize the nutrients.The key is picking fertilizers that provide a burst of nitrogen, potassium and phosphorous.In addition to the liquid fertilizing intervals, power mulch your plants for even more success.And mixed into that compost is a quarter cup of worm castings to add even more slow-release power.Once a plant hits full production mode in mid-summer, it is time to cease fertilizing all-together.At this point, the plant will only use the added strength to grow additional foliage – and not produce or fill out the blooms and young crops on its stems and vines.In fact, fertilizing vegetable plants too late in the summer can actually decrease yields.You can sign up for our free email list in the subscribe now box in the middle of this article. .

8 Best Homemade Natural Garden Fertilizers

Some of these fertilizers can be made or collected at home using common items from your pantry or your backyard.If you have an organic lawn, make sure to collect your grass clippings to use on your gardens.Just like grass clippings, many of the weeds that you’ll find in your gardens are very high in nitrogen and will make an excellent fertilizer.Then fill the bucket the rest of the way with water, and let the weeds soak for a week or two.Compost releases nutrients slowly, which means a well-composted garden can go a year or two without requiring reapplication of fertilizer.Compost also helps the soil retain moisture, which is essential for vegetable gardens to thrive during hot, dry summers.Leaves are rich with trace minerals, they attract earthworms, they retain moisture, and they’ll help make heavy soils lighter.Lots of plants, such as blueberries, rhododendron, roses, and tomatoes, thrive best in acidic soil.There are a couple of ways to do this— you can either top dress by sprinkling the used grounds over the surface of the soil, or you can make “coffee” to pour on your gardens.If you’ve ever used lime on your garden, then you know it comes with lots of benefits — chiefly, it helps lower the acidity of your soil for plants that don’t like acid, and it provides plants with lots of calcium, which is an essential nutrient.Lime itself is an all-natural fertilizer that you can buy at the garden center, but if you’d rather save some money, there is a cheaper way to get the same benefits.Simply bury peels in a hole alongside the rose bush so they can compost naturally. .
