The pepper plants I purchased each had 1 fruit on them when I planted them 2 months ago. Why are no more fruits forming? They get full sun and water twice a day.
If the plants are healthy, try a fertilizer with phosphorus( 8-8-8). Only water when plants need it. Insert a finger into the soil and if it feels damp wait to water. If the plants are healthy and flowering, it is probably due to the excessive heat we've experienced this year.
