How long does it take to fertilize tomato seedlings about 1 and 15 days after transplanting?
After tomato seedlings are transplanted, fertilization is needed. Generally, it is best to apply it about 15 days after transplanting. At this point, the tomato seedlings have completely survived and started to grow. We can apply seedling fertilizer to them, which can promote root knot and stem and leaf growth. The fertilizer can be organic fertilizer.
Step 2 Apply base fertilizer
The growth of tomatoes needs sufficient nutrients, so when planting, it is necessary to apply some decomposed organic fertilizers and phosphorus and potassium fertilizers as base fertilizers to improve soil fertility. Otherwise, if the soil is too poor, it is difficult for tomatoes to grow vigorously and the yield is low when they bear fruit.
3. Topdressing
Tomato needs topdressing in the growth period, and topdressing in the flower and fruit period, and topdressing once after each tomato harvest, and spraying some potassium dihydrogen phosphate solution as foliar fertilizer in the fruit growth period is beneficial to tomato fruit growth and maturity.
4. Preventive measures
When applying fertilizer to tomatoes, we should pay attention to the principle of applying thin fertilizer frequently, and neither raw fertilizer nor thick fertilizer can be applied to avoid fertilizer damage to tomato plants. Also be careful not to apply nitrogen fertilizer in a biased way. Generally, it is best to apply fertilizer together with phosphorus and potassium fertilizer, otherwise excessive application of nitrogen fertilizer will affect the flowering and fruiting of tomatoes.
