MY WISTERIA is 2 yrs. old and the same size now as the day it was planted. (full sun on a fence in the backyard) It will look beautiful and green and then go kinda pale green yellow (like a dog whizzed on it). I know it’s not animal whiz because we put a small fence 1 foot from the base all way round. What am I doing wrong?
CONCORD GRAPE VINE is great, in its 3rd year of grapes, but they are never larger than a champagne grape (large pea). How do I make the grapes grow larger?
HONEYSUCKLE is yellow/orange. Can you root new shoots from an older vine?
For the wisteria - there is a general rule of thumb about wisteria and this is that the first year they establish, the second year they relax and the third year, they take over. Give it another year and you should see healthy and active growth. As for the yellowing, increase the water some and give it some balanced fertilizer and that should help.
For your grapes - You may need to do selective thinning. This article is on seedless grapes, but the advice still applies to your Concords: http://aces.nmsu.edu/pubs/_h/H-311.pdf
For the honeysuckle - Yes, you can. This article will help with that: https://www.gardeningknowhow.com/ornamental/trees/tgen/how-to-root-cuttings-from-various-shrubs-bushes-and-trees.htm
