I want to eco the previous comment made by californicus, very impressive!!
It is fun to see all the different mulberries you’re growing, I am so jealous!! I liked many of the videos and I subscribed .
I have two weeping white mulberry trees. One I bought from Burnt Ridge Nursery the other one is a cutting from the tree at the pool. The growth habit and look of the leaves is the same but the fruit ripens and tastes slightly different, I think It may have more to do with soil conditions then variety. I planted the trees only about 7 feet apart… But the tree I got from Burnt Ridge I dug a hole about 4 feet wide and 4 feet deep and filled it with nice topsoil. The cutting I only dug a hole about thrice the size of the pot I grew it in and back filled with black gold potting soil, I have to put nitrogen fertilizer on the cutting tree to keep the leaves green. The soil surrounding it is the existing polluted garbage soil my Grandpa brought in from an old gas station, long before my wife and I bought the house.
This year I tried rooting cuttings from scion wood I bought Brent Ridge Nursery. I tried Pakistan mulberry, Illinois Ever Bearing, Sweet Lavander, Kokuso, and Black Beauty. Unfortunately none of them rooted. All of the buds were swelling looking beautiful than I came out one day and to my dismay and disgust all of the buds had been badly damaged or completely eaten off by a slugs. They never recovered after that.
I did try grafting them onto my weeping mulberry tree as Insurance and I had Illinois Ever Bearing, Black Beauty and Kokuso that took and I even got some yummy mulberries off of them this year.
I think what I’m going to do is go to Burnt Ridge nursery or One Green World and buy the biggest healthiest Pakistan tree I can get than graft other verities onto it.
