Thanks, Willi. I try to remove the needles from the plot, anyway, and the soil's beautiful otherwise. The tree's in the northwest corner of the plot, so it does get plenty of sun. I think I'll just go for it! Thanks!
I listen to you on the gardening segment on Weekday sometimes. Cool you're on here! I hope it's okay for me to ask you a gardening question... I've never grown any kind of potatoes before, but am looking to grow something "underground" that won't be affected by needles that will be dropped on it by a tree (spruce, I think). From my brief research, seems that potatoes like slightly acidic soil. I'm assuming this patch is pretty acidic. Is it the needles that acidify the soil or the tree itself? I think the tree is sick due to the vastly increased amount of needle droppage in the past couple years. I usually amend the soil with lime, but am thinking maybe I shouldn't if it's gonna grow potatoes. Any advice?
