Mary Stella, I bought those same planters from Costco! I love them! I've got gourds planted in mine, and I hope they do good. I have a pergola over my deck that has a retractable top, but the wind always blows the top open. I'm hoping that the gourds will cover the pergola instead, and we can get some much needed shade on the deck.
I have no idea if the raspberries are going to do okay in the buckets, but I hope they will be fine. At least they look very healthy right now. I planted a clump in one, and then two in each of the others. Lost one in one bucket, but there is still one growing in there. I'll be shocked if I get any raspberries this year, but I'm fine with it if I don't. At least I got them out of the daylilies, which was more important than anything. I drilled holes in the bottoms of the buckets, and then lined them with plastic landscape fabric. I sure hope that works to contain the roots.
