Sizing up
Go up one pot size — about 2–3 cm wider than the old pot. Any bigger and your plant might go into shock.
Two plants, one bag
Our bags are resealable, so leftovers keep. Buy the next size up if you've a few pots waiting.
Which mix
House Plant for most things, Chunky for monstera and tropical plants, Cactus & Succulent for the dry lot.
