In first photo 2 spots look like ringspot virus.

The one thing where there is a hole in the leaf with some brown stuff can be stem borers. I hate those things. :( If you break off where the hole is, you can sometimes see a worm in there. I had them really bad one year, they did that to my raspberries and other weeds around here.

I did the solarization & it worked, but I have been busy retiring & cutting timber so I can set up a SCOC garden & orchard. Now if I can remove 100 pine stumps I will be on track, stump grinder or saltpetre should do it , may have to dig them. Anyways I killed everything in one shot, but if you use solarization, you will have to rebuild the microculture. May I say that mycelium from Wine Cap mushrooms is the best of both worlds. WCM are great composter & you get to eat the flush two or three times a year. I going to use WCM in all my knew asparagus/strawberry beds, 4 inches of woodchips will not last long, but can be replenished annually or as needed. I would put them on the pine stumps, but they need hardwood chips. https://www.google.com/search?q=solarization+to+kill+weeds+with+plastic&oq=solar&aqs=chrome.4.69i59l2j69i57j69i59j35i39j69i61j69i60j69i61.18904j0j7&sourceid=chrome&ie=UTF-8

Very interesting! -herbalbetty, what is oatstraw? Im guessing its not a combonation of oats and straw... -Annie, now thats a list! Do you use only one of these at a time or do you mix them up? Whats your favorite concoction? And (im not sure id do it or not, just curious) does it have to be a spicific kind of pine needles? I want to try lavender and bergamont sometime. I tried Lemon Balm tea and didnt like it. It was like I was sucking on a citronella misquito candle. Ps. I read something interesting about the history of Calendula officinalis in my herb book. It got its name from the Romans because this plant could be found blooming every month of the calendar year around Rome (Calendar=Calendula). And a long time ago Calendula was used to flavor and color butter and cheeses. Im not really a 'self medicating by herbs' kind of person, but I enjoy reading about them in my herb book. Its called The Complete Book of Herbs- by Lesley Bremness. It has a photo and description of the plant and its history. It also gives culinary, medical, and cosmetic uses as well as info on how to cultivate, harvest, preserve, and use the herbs. CMK
