To use crock? Or not to use crock? That is the question

[jk]

I don't know if I'm understanding this correctly, but if the crock creates space in the bottom of the pot and if you are using the water tray method, I don't think it's advisable to use crock because it would mean that the medium would dry out when there's still water in the tray when it's at a level that's lower than the upper level of the crock.

Thanks for the responses. JK I have the same train of thought on this as you do but pretty much every gardening book (nonCP if I’m honest) says it’s important to use crock.

Thanks

Regarding the use of crock in containers with the usual types of plants, the addition of coarse material at the bottom of containers does not improve drainage, and it may hinder growth (contrary to common "knowledge"). If you are willing to read a long (but rather interesting) explanation, see:

Alex, I'm thinking that D. capensis would be growing like a weed in your climate. D. capensis doesn't seem to be picky, as long as the medium doesn't go bone dry for a long period of time, it doesn't seem to care either way. I've got it growing in various conditions ranging from flooded undrained conditions all the way to shallow, drained trays that go dry between waterings and it doesn't really care. If you're on the lazy side like me, then go with an undrained container or just don't bother with the crock.
