Q.transplanting sweet peas
My sweet peas are just starting to flower and are about 2′ tall. Can I transplant them or is it too late? I originally planted them in the back of my veggie garden, but now I wish to put them somewhere they can be seen better. Will I kill them if I try to dig them up at this point?
You should not move them now, this would most certainly cause stress and likely loss of flowers or the plants themselves.
Enjoy them this year and make the planting change next year.
