should you fertilize or feed tomato plants
Tomato plants use phosphorous and potassium in significant amounts to produce fruit. Fertilizer that contains nitrogen, phosphorous and potassium in a ratio of 8-32-16 or 6-24-24 is an effective source of phosphorous and potassium for tomatoes in soils with low concentrations of these nutrients. The best time to apply this type of fertilizer is before you plant your tomatoes. Once you have established the desired level of fertility in your garden you can apply subsequent doses of fertilizer as side dressing at a lower concentration to maintain a fertile growing bed for your tomatoes.
