I buy plants usually 4 plants per tray. I plant several different types of pepper plants in the same row. Bell, Banana and maybe another type. My Bell pepper plants always seem to grow slow. I usually have the plants in the ground by the end of April or the first part of May. I have a problem with them the root system is never strong enough to hold up the plants. June and July thunderstorms usually blow the plants over so I have to pile dirt up like a volcano on the plant to hold it up. The next big rain washes the dirt away and the plants fall over again. Last summer I staked the plants to hold them up. By Aug the plants will be about 2 ft tall. There are usually a few small peppers on the plant by then. By the end of August the peppers are the size of a tennis ball. We typically have 100 deg weather in August and usually only 1 rain for the whole month so I water the garden every evening. In Sept the plant starts growing more peppers and they get larger. October when the weather is cooler the plants will have maybe 15 to 20 bell peppers and much larger.
The Banana peppers are not much of a problem I have a lot of peppers my mid July but I still have a problem with the plants falling over is that a typical problem with peppers?
