Cactus / Grafted offsets 2

This is a grafted offset of Aztekium ritteri onto Pereskiopsis.
I grafted 4 offsets last October.
It has been growing vigorously and pushing many offsets up.

Tuesday, 9 June 2015

Cactus / Grafted offset

The body tissue of an offset is harder than that of seedlings.
An offset of Aztekium is hard especially.
You need pressure onto the scion when you grafted a hard offset normally but I found you do not need any pressure for these scions if you used Pereskiopsis as the stock.
I grafted 7 of Aztekium hintonii offsets in October last year.
The success rate of the grafting will be lower than seedling but it will be high enough if you use more than 10 mm diameter.
The photo is 1 of them, 40 mm diameter currently.

Cactus / Grafted seedling 5

It seems various theories for positive/negative genes of the crossing cacti.
I have been still not sure mother or father genes to work positively for children.

I have grafted 12 of each.
