You have been growing seedlings in small pots and it’s time to move them to bigger pots. Or maybe you bought a small houseplant and it has grown too big for the pot and it needs more space. What size of pot should you use when potting up? Is it better to pot up one size at a time, or go to a big pot right away?
Is there a right answer or does the answer depend on your goals for the plant, the type of soil or the type of plant?
The answer is going to surprise many of you and it’ll show the value of listening to science.
