Help, please. One of my flower beds is infested by grape hyacinths. I have tried to eliminate them by removing the sand and sifting out the bulbs, but the darned things keep popping up again. What can I do to eliminate them completely?
Infested? I should be so lucky! Our condo is going to plant them this fall. If not already up, the leaves will be emerging soon and you can pull them. Mine are already showing in some places. (nice when you're digging in new bulbs!) I've noticed that they seed readily, so deadheading is a must.
I guess if you want control you could plant some of the sterile hybrids.
I just visited my daughter's house and found that the grape hyacinths are through her lawn just as the scilla sibericas are through mine. I guess it's the ants again. I passed along some info in another forum: the ants take the seed covers of the scillas home as food, and on the way they drop some seeds. It's a hoot to see the drift from my garden to two units over, which was sand storage during construction.
Guess the ants like grape hyacinths, too!
