Companion planting guides say to put dill near your brassicas as it is supposed to improve their flavor -- ? I can see bugs &/or soil improvement but, flavor. Hmmm.
Also...they say keep tomatoes from Walnuts. Since you have several nut trees, I mention this. "They" never said why -- and I can't see much being planted in that situation as the trees create shade. Suppose could happen within a close area if the garden, trees & sun were aligned in a complimentary fashion.
I had started some seed for cabbage, pak choi, broccoli, etc and due to my own laziness, they are being hardened off right now. Yep, left them out on the back porch, where they sit in sunshine a good part of the day. Tomatoes are in soil/cups but not germinated yet. Yep, outside also. But our temps have been those of our normal April, this month. Plus aver is 50 right now, it's been closer to 70 most days. So I think it's ok. Only down to 40 last night --with the NorEasterer of the coast I have winds of 25-30 steady and 40-45 gusts! Can't do much out there. Plants are not in the wind.
NOTE: as I was about to post this @ 9AM, the power went out! Felt it may have been a tree down on a line -- with all the wind and rains for past week! -- I left couple hrs later for work and power back on 4: So, this was still waiting for me to hit the post button... LOL
