How to maintain moisture levels in pots / containers?
Hi all. I'm assuming this question has been asked and answered many times, so feel free to point me towards any previous threads. Otherwise, what tips do you have for moisture levels in pots / containers in the garden?
I've largely steered clear of pots in the past as I don't remember to water them (and when I've watered hanging baskets, more water ends up on me than the plants!) In a recent GQT, Christine Walkden I think mentioined putting bits of sponge in the compost but there are water-retaining crystals I think, so any advice on cost / re-usability of these or any other tips welcomed!
