local chill hours

Hello, I was wondering if you could help me find my average annual chill hours to help me choose varieties of fruit trees to plant. I know about the app run by MSU, but this app does not seem to be capable of giving data for past years, only the current years. Thank you!

Clay dirt

My garden has clay soil. I heard that doing a winter cover, Austrian peas or wheat over the winter would help. I can’t seem to find any of these items. Where could I find these items? And will it really help? Is it worth doing? Live near Detroit Michigan.

Empty Mammoth Sunflower Seeds

Why do most of my sunflower seeds not have a seed in the middle? We originally grew them for a project in February (harvested them June 3rd) , and we kept growing them out. We recently cut the heads off and harvested the seeds, then we followed an online recipe on how to cook them. After cooking them we found that most off them don't have seeds. We haven't eaten many but most of the ones we have eaten had no seeds. We are wondering if we need to let them grow longer.

ginko leaves not turning golden in fall as they used to

My Ginko tree is about 45-50 years old. It used to turn beautiful golden in the falland the leaves all drop at once. The last few years it has not done this. I miss the golden leaves.

Blue spruce disease

We have 3 20 ft. Blue spruce in our yard. Last spring I noticed the white "bumps" on the needles. The infected needles start on the inside and bottom of the tree and work their way up and out. I sprayed the trees all summer with a fungicide at 2-3 week intervals and I thought that it slowed the disease but now this spring it seems to be very active again. We live at high altitude with desert like weather...any help would be greatly appreciated!
