How many hours?

I am trying to grow spearmint and chocolate mint. I know that mint plants require partial shade, but how many hours of the day should they have sun and how many hours should they have shade? I want to be sure that they get the right amount of each.

Identify a plant

This plant is coming up very prolifically in an area where I planted a bag of wild flower seeds. The area was very weedy before I killed off all the vegetation with glyphosate. There are about 4 stem that come off of the central hub. Each stem has 8-10 leaves and small white flowers are emerging from the center. Can you tell if this is a wildflower or a weed. Thanks, Gary Meyer

How often should I water?

How often should I water my vegetable, herb, and berry garden during hot spells like the one we are experiencing now? In the early morning the plants look ok but by evening they look wilted and the leaves droop so I have been watering them almost every other morning. Every time I do, the ground on the next morning looks so dry that you would not know that I had watered the previous morning. Most of the leaves have remained dark green but a few have turned pale green or even yellow. Am I watering too much or too little?

Suspected walnut caterpillars

My adolescent shagbark hickory has been almost denuded in 48 hours! I found a trail of carcasses on the trunk and these wooly guys munching and pooping to make it almost rain under the tree. They are too high for me to reach with a Bt spray bottle. My other adjacent plants are oaks and redbuds and are happily ignored. Am I right what it is? Are there suggestions on how to handle?
