THE AGRONOMIST ANSWERS ON HOW TO GROW AND CARE FOR PLANTS
HOW MANY MALE PLANTS SHOULD BE ALTERNATED TO FEMALE HOLLY PLANTS?
QUESTION OF MIRELLA
Hi, I read with interest an answer given on the cultivation of holly. I would like to cultivate it and then produce it as "cut". I didn't know there were 'male and female' and based on this detail, how many male and female plants will I have to alternate to get red berries? how do you distinguish themselves ?. I would like to plant it at a distance of 70 centimeters between two rows of "Evonimus" always cutting do I do well or is it preferable to opt for other solutions? Thanking I send cordial greetings
as for the ratio between "male plants" and "female plants" of average holly is one male plant every 6, maximum 8 female plants, placed close together so that pollinating insects can find them.
As for the recognition of the sex of hollies you can only find out from the flower as the other morphological characters are completely similar. The holly flowers have four petals in both plants and those of the male flowers are usually white with reddish margins and obviously have anthers while that of the female plants are white with a green ovary.
In any case, when you go to buy them, the nurseryman will be able to give you the right ones. Keep in mind that hollies are a protected species and therefore cannot be harvested in the woods.
The plant alternating with the evonymus can be fine but the sixth plant is not good, definitely too narrow taking into account that hollies are trees that if well bred easily reach 10 m in height (in Sicily, where they find ideal conditions there are hollies up to 18-20 m).
I hope I've been useful. If you have any doubts, don't hesitate to write me again.
