potting peppers: ideal growing medium and container size
this will be my second year trying to grow hot peppers, so please excuse my ignorance...
im wondering about the ideal soil(less) mix. ive had limited success growing hot peppers (jalapeÃÂ±os, habaneros, serranos) in a mix of potting soil, sphagnum, top soil, and manure. in fact, i planted about 10 plants in my raised bed last year and only harvested about 5 peppers total! i did, however, plant a tabasco pepper plant that exploded in late summer, constituting my only pepper success story last year.
this year i'm growing different peppers from seed under a grow light. im planning on planting some in my raised bed, but i'd like to plant the majority in containers for mobility and to experiment with soil mixes. im guessing my peppers didn't do so hot in my raised bed due to the high water retention of the soil mix, so i was thinking of just mixing course sand with potting soil for the container peppers to create more drainage.
any suggestions as to a simple and effective medium for potting hot peppers (i'll be planting habaneros, scotch bonnets, and serranos)? also, what would be a good container size to allow for full maturation without restricting growth?
any tips would be greatly appreciated!
