Thank you Gastil. The containers I use hold about 30 litres I think. So weighing is not an option. I am fussy about it now, as my Rainlilies were getting Stagonospora. I have spent 6 months going over most of them as per Wiki instructions, which has been a very tedious job indeed. Hence being planted in containers in pumice, as that seems the best way to keep them dry. However, they could get too dry. And I cannot tell how damp it is around the root level. I can stick a finger in, but that doesn't tell me anything about the root level. I can water regularly, but even with pumice, that would be too much moisture for the Rainlilies. Temperature can be indicated with a strip of something. I wonder if there is anything like that for moisture. Ina Ina Crossley Auckland New Zealand zone 10a On 1/12/2013 2:42 p.m., M.
