Exposure Subalpine firSole pieno
The Subalpine fir should be grown outdoors; it can bear very harsh temperatures without any problems, even many degrees below zero. To prevent damage caused by the cold temperatures, during the months with definately harsh minimum temperatures, we can protect the shrubs by covering the soil around the stem with straw or dry leaves.The Subalpine fir should be grown in a bright place, with direct sunlight.

Generalities Subalpine fir
These plants develop like conifers. The Subalpine fir Is small in size; in spring, summer, autumn, winter it assumes a green colouring. These are evergreen plants, which means they keep their leaves year round. These plants have an erect development; in the lower part they usually show a bare stem, while towards the top they widen to form the crown.

Fertilization Subalpine fir
Shrubs develop new shoots and prepare their flowers during the spring period, therefore we must remember, by the end of the winter, to give it a good dose of humus or mature manure, or granular slow release fertilizer, to be added to the soil at the foot of the plant. During the spring we can choose a fertilizer rich in nitrogen and potassium, to mix with the irrigating water, every 20-25 days.

Watering Subalpine firTenere asciutto
Water rarely, about once every 2-3 weeks with 1-2 buckets of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down. If we want to grow these plants in a vase, we should water them a bit more often, compared to plants cultivated in the ground; Every 2-3 years we should renew the substratum in the vase, or enrich with organic amender.

Treatments Subalpine fir
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 Subalpine fir
For these shrubs it’s necessary to choose a rich and deep substratum , which presents an excellent drainage.
