Your tomatoes and peppers are very sensitive to the amount of nitrogen you give them, where many other plants are not.
The Hack: Low nitrogen fertilizers or mulches until the first fruits are the size of golf balls (they’re recommending a 6-24-24 (N-P-K)), then switching to a higher nitrogen content such as 15-15-15 or 20-20-20 when the plants can utilize the extra nitrogen. This hack works for Tomatoes, peppers and eggplant, too. Wonder if the same happens to their cousin the potato? Any one know? Please sign in and leave a note!
