It should be aired every two days to avoid mould formation.
These cuttings will be taken root after three or sometimes four weeks. The plastic bag must not be removed before the three weeks.
A successful propagation means that the cutting should be green and growing slowly. If the cutting is brown and dry, this means it will not have taken root.
The successful propagation can be in the open air and should be fed every four weeks.
