The soil should be loose and light. You cannot compact it or trample it.
This is because mahonia grows slowly, and compacted soil can create additional difficulties, thereby slowing its growth even further.
The distance between seedlings is at least one meter.
Try to choose a well-lit area that is well protected from strong gusts of wind.
If you are going to cultivate the plant for decorative purposes, and not for its fruits, then you can plant mahonia in the shade.
Therefore, it is drought-resistant and does not particularly need fertilizing.
It is enough to fertilize twice a year, in spring and autumn.
It grows a thick crown well and can do without pruning.
Nevertheless, it is necessary to cut out weak, dry and frozen branches.
The plants' diet is balanced, and in the first year of intensive growth, they will not need foliar feeding.
Then do not forget to feed the mahonia with a “mix” of humic substances, minerals and amino acids - especially since the Lignohumate line contains preparations that are excellent for these purposes.
