Meet the Homalocephalas

[iann]

One splash of water shouldn't do any harm, especially E. parryi. Just don't let them sit in soggy soil. They are nowhere near as touchy as Sclerocactus. Just that E. polycephalus isn't going to grow in summer and trying to make it is going to end in tears. Looked at a different way, failing to make the most of the very short and early growing season won't get you very far. For the first few years, seedlings will want more regular summer water (or shade, which may be a worse choice), and might even push out a new areole in summer. Probably they have to grow or die through the first year or two and only the ones that get unusual summer rains will make it. Adults should only get enough water in summer to stop them losing their roots. Their shape means they always look quite thirsty - even with generous water in early spring, adults will never approach spherical (maybe if grafted, but then what's the point?).

Thanks for all the info! Will be sure to keep this in mind for the future

Some nice spiky mikeys. Is it me though or does the first one looks like it really needs a drink?

It is a little thirsty, but nothing out of the ordinary. You can inflate these to almost spherical, but who would want to? Some of my smaller plants are definitely prettier though.
