Hi! May I ask you, I have A.Retusus grafted on some Echinopsis. I have bought this plant recently. Scion have 8 cm size. Echinopsis have had some side shoots, but I remove them because they was already separated and with own roots in soil. Seller tell me that plant is 8-10 years age.
The stock is already fully lignified, has no green surface, is firm, but still large, about 5 cm, with well-developed roots. Since I received the plant without soil, I transplanted it into a very well-drained mineral substrate, and I decided to cover the Echinopsis and even contact line 1-1.5 cm above. Do you think Retusus will be able to break through the stock and grow its own roots over time? Or should I still remove scion completely? I don't want Retusus to stress when fully degrafted and at the same time I'm afraid that at some moment of time Echinopsis will just rot and I just won't see it in time under the soil. I read that you use the short Pereskiopsis method, but does the same method work for Echinopsis? Echinopsis is significantly larger and woody and have larger contact square, but usually sitting not so deep in scion.
Anyway, I need wait to spring if need full degrafting. I wouldn`t degraft Retusus at all if it possible, as long as plant filling well. You have degrafted many Ariocarpus scions, can you confirm that Ariocarpus don`t grow tap root over the years? Will Retusus grow more flat after rooting or rooting doesn`t change its form cause taproot doesn`t appear anyway? And will Ariocarpus grow faster or slower after degrafting from Echinopsis and rooting? Thx!
