Of course, everything you read from the company is good. SO need some help from you. Let me know. Becky
Your supplier should be able to give you all the cultural info you need. Otherwise this should help.
Geraniums types all have the same basic needs. What you need to know is what their vigor is so you can match them to the correct container to be finished in.
I grew elegance burgundy last year (regal geranium) and just loved it. It sold out before spring really even got here. I ordered more this year through ball. It was real easy for me to grow and liked cool temps in the early greenhouse. Not picky about ph, and we had it hanging in the attic of the greenhouse close to the intake vents and it didn't mind a bit.
The only change we're going to make is to put 3 plants in a 10" basket instead of four. It looked a little crowded by finish time.
