Baby agapanthus - no-gro!

:cnfs:I have 3 small agapanthus plants which came off a parent plant and are in separate pots in the greenhouse. They stand about 3cms above the compost and I cannot get them to grow any bigger!! I have watered them, let them dry out a bit, fed them with a variety of stuff but they have been the same size since last summer. The best that can be said is that they haven't died! They're in 4" pots - could these be too big? I'm stumped. Any ideas? Thanks - Lindy.

 

I have this issue too-they are being very slow this year, the only thing I can think of is that it was a dry spring.

 

I also have a he same problem with an established aga. planted 2 years ago which is very slow this year, and another new bulb aga planting this year which is only a couple of inches growth.
Must be what Lollipop said ;-)

 

Thanks folks. I'll wait and hope for some results. Lindy
