Columnar Trees
« on: July 16, 2019, 09:43:06 PM »
Does anyone know how columnar tress  are made. I have never read of a columnar citrus but I wonder if it could be done. You could certainly fit more in your and greenhouse if columnar.
My name is Cindy

Normally, by genetic selection of fastigiate cultivars. In gen Citrus, by pruning and tying the branches to the trunk to force them grow in a narrow angle. Citrus is not a fastigiate growing kind of tree. They always develop a broad canopy with time. Stems in a very acute angle will catch rotten fruits, fallen leaves and diseases

Using several narrow trees, instead a single wider tree, mean less fruits and more trunks/wood in the same space. Multigrafting a tree looks like a better solution

I tried to make a C tree out of poncirus to save space. It is 6 years old, looks like a stem with short branches and is unhappy. I dont think citrus is designed for the C shaping. Try apples, might work there.

I built one by accident. It wasn't meant to be columnar. The cultivar is the Sudachi hybrid. It develops fruits like grape clusters enclosing the stem. I marcotted one with lots of fruits, and so it looked like a columnar citrus. I gave it away as gift, long before our quarantine, I didn't care about columnar fruit trees.
