The space where I grow outside has become crowded. I have 5 plants in 25 gal fab pots and one in the ground. The roots have grown through the bottom of the pots into the ground, so I can't move them. 3 are already into flower, but the one in the ground is still in veg and its branches are starting to grow into the other plants --- its a Malawi and its like 12 ft already. The other two in pots are Malawi, but they are not growing out as great as the one in the ground. Any suggestions as to how I can fix my space?
