Thank you, nmoasis for the info. I have been trying to grow plants to attract them. Those were my instructions in 2019 whence a friend's son was going to help me put in some plants. He suggested Frog Fruit--attracts bees and butterflies. This year, I put in a lot of Salvias. The bees were going crazy over them at the garden centre. I now have some mini roses in pots, too. I have Turk's Cap in a huge pot as well. I am somewhat limited on space.
I saw a segment on a programme some time back (maybe it was on P. Allen Smith's Garden Home) where a guest spoke about having an insect house in your garden and showed out to make one with tons of nooks and crannies. I looked into buying one this year, but the ready made ones had poor reviews. I might have to revisit an how-to video on YouTube or something. The one thing I worry about is attracting more wasps! I would love to have a bee keeper keep a small hive here, but given the people around me, I fear they would not be safe. People around here would automatically kill any insect they thought might sting even if it did not sting them. It is really disheartening. I have one bed area left that is pretty big relatively speaking that I would like to develop either this Autumn or next Spring. I fear I am not up to getting the ground ready myself. I may have to look into what it would cost to have the ground done, and then I could do the planting. I would be thrilled to walk outside and find sweet little bees everywhere.
