Gray alder Alnus incana

Exposure Gray alder
With a particularly windy climate we suggest securing young trees to long solid stakes, to avoid that the wind could bare young and not very developed roots; specimens which are only a few years old might fear intense cold and wind. The Gray alder should be grown outdoors; it can bear very harsh temperatures without any problems, even many degrees below zero.The Gray alder should be grown in a bright place, with direct sunlight.

Watering Gray alder
We advise watering the young specimens, or the recently sheltered ones; the adult specimens usually are satisfied with rain water. During this period of the year the The Gray alder needs regular watering, which should be done letting the soil dry between one watering and the other; let’s irrigate every 2-3 weeks with about 2-3 buckets of water .

Fertilization Gray alder
Tree fertilization should be done at the beginning of the spring or of autumn, using humus or mature manure; this should be done by mixing a few buckets of fertilizer to the ground, around the trunk of the tree, every 2-3 years or when the tree implanted.

Treatments Gray alder
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.

Soil Gray alder
We suggest a pretty rich, quite soft, but not too drained, growing substratum.
