First time raised bed gardner here. My start from seed seedlings did not do well after transplant so I bought some of the last pepper, zucchini and tomato plants I found at the local nursery. I just put them in the ground two weeks ago and they seem to be doing OK. I have read some info on growing and in that information I have read that you should pinch off the first buds/flowers to encourage plant growth before producing. The Early Girl tomatoes are about 18 inches tall and have the first flowers on them. Cubanelle peppers are about 30 inches high and have a lot of buds. Should I leave them or pinch them off? I haven't read about pinching off the zucchini buds/flowers, would this be beneficial to them as well, they are about 12 inches tall now. Included pics of toms and peppers. Thanks!
