Ive always grown in the ground until last year...I used pots last year and had awful luck!...I blamed the heat up until about 4 days ago!....Sure, its sometimes 120+(Farenheit) but I think, after all, my pots were too small! Sometimes I'd water and the soil was bone dry! after thinking on this I decided this year I'll go back outside but use bigger pots! I mean, it makes sense...bigger pots will hold water longer! And, the sun is free compared to making my cabinet functional!Also, where my cabinet is, without the AC going, that shop will hit over 120 in the shade!..On another note...in the ground, my plants never grew shorter than 10 feet! Honest!..Last year i grew blueberry in the pots...They never grew over about 4 feet...just so you know..and, in you ground them put a screen basket around them for awhile...Rabbits will munch and armadillow will dig the soft moist dirt and break your plants!
