Plant vs. Pot size - when to upsize
As I can't place many of my plants in the ground, due to weather and watering restrictions, I have held them on life support in pots. Here's the question. How do you know what is the right size pot? Many have grown larger and I don't know if I should move em on up, to the next size (somebody get that play on words please or I will feel old). It there a formula for height and spread in corralation (sp) to the pot size? I don't want to stifle what has been a long and arduous task keeping them alive in this weather, only to kill by smothering. Any advise would be fantastic.
