What’s the best fertilizer for a vegetable garden?
Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don’t need more. Leafy vegetables do well with a balanced nitrogen-containing fertilizer such as 10-10-10 or 16-16-16 (Table 1). Vegetables grown for their fruits, seeds, roots or bulbs will thrive on a pre-plant fertilization with a low N complete fertilizer such as 6-24-24, 6-12-18 or 8-16-16.Most vegetables will do best with a balanced fertilizer—something like 6-6-6. But there are some exceptions. Leafy vegetables may need only nitrogen to grow large, tender foliage, and root crops such as sweet potatoes, potatoes, beets, carrots, and turnips often benefit from an extra dose of potassium.Most vegetables will do best with a balanced fertilizer—something like 6-6-6. But there are some exceptions. Leafy vegetables may need only nitrogen to grow large, tender foliage, and root crops such as sweet potatoes, potatoes, beets, carrots, and turnips often benefit from an extra dose of potassium.Usually a balanced fertilizer is applied every three to four weeks throughout the growing season. Don’t stop applications when fruit appears—continue to apply fertilizer as needed to ensure continued production. Vegetables growing in clay soils will need less fertilizer than those in sandy soils.Pick a fertilizer with an NPK ratio of 8-32-16 or 6-24-24 for best results. Instructions for spreading the product will vary with the type of tomato fertilizer you choose. Tomato plants require enough phosphorus supply to ensure a healthy fruit set.
Should I water my plants after fertilizing?
After fertilizing your plants, you need to water your plants thoroughly and regularly. Answer: Early morning (5:00 to 9:00 am) is the best time to water the garden when using a sprinkler, garden hose, or any other device that wets the plant foliage. When watering is completed, the plant foliage dries quickly. The rapid drying of plant foliage helps guard against the development of fungal diseases.Never sprinkle it on top of the soil and then water as this can easily burn your plants. When you water, direct the fertilizer-infused water towards the roots of the plant. There is no need to get the foliage wet since the nutrients will be absorbed by the roots, not the leaves.
Should I fertilize soil before planting?
When broadcasting fertilizer before planting, the proper amount of fertilizer is spread evenly over the garden and mixed with the soil to a depth of 3 to 4 inches before rows are made. This method is the least likely to cause plant damage and usually is best for home gardeners. It need not be worked deeply into the soil—the upper 3 to 5 inches will do. Then, water in the fertilizer. For perennial flowering plants, fertilize before growth begins in the spring.
