Fertilizer for Cuttings

[flos]

When do you start fertilizing cuttings?


I have a cutting whose root development I would like to accelerate. I am aware that the first roots may still be a bit sensitive. Is there a rooting hormone that can be watered after successful rooting?

You can use so called Superphosphates which Help newly planted trees by rooting

Possibly kelp based products. Don't forget temperature of the soil or pot media as a factor to induce rooting.

I know superphosphate. But you would have to concentrate it a little weaker. I am a little afraid to destroy the few roots. At least if it is something rarer.

Algae powder is also available, this would be perhaps for fresh roots to consider.
I will test both times at the opportunity.
