Here I am again. I also placed the question on the topic 'A few new blooms from this morning' from 'Kaboehm', but nobody read it I think.
I bought at the end of 2010 some bulbs, around 31 cm. But now the're just 24 cm (the one I've measured), and the rest is also less. I had them in the greenhouse last year and gave them every two weeks fertilizer for houseplants. So I have the idea that they don't grow very well. But they're in good health. No virus or anything else. It's a Gervase, Faro (?), Orange Sovereign and a red one. Any idea what I'm doing wrong. The Gervase shows already a tiny top of a bud and he is 24 cm circumference.
