I was so late in listening to this podcast but I knew it would be a good one with TONS of good info and I surely wasn't disappointed.
I definitely have the magnesium deficiency thing going on
Had it last year as well.
We've grown tomatoes for over 40 years and I do believe this year has been the most challenging. NC has had 3 times the rain it usually gets and the tomatoes are definitely pouting and the fruit is cracking.
I planted marigolds around the tomatoes this year and haven't had tomato worm issues.
We don't kill spiders or wasps either. I'll have to photograph for you, the mud dobbers have laid their mud completely around the thermometer on the back porch (among many other places) Fortunately it's on the cold side so I can still see the temp. They LOVE our back porch.
Again, I can't tell you how much I enjoy these podcasts. So much information for us.
Thank you!
