Hi

I have some new 'baby' (don't know the botanical description)
Zantedeschia's, they are in small pots on a utility room (not very warm)
window cill which gets some light. They all have two leaves (2-4inch tall
approx) and whilst slow growth right now is slow some are very green and
healthy looking and some are looking a bit blotchy. I really like these and
don't want to lose any, please could somebody give me some growing advice ?
