These plants develop like conifers. These plants give origin to a brush with a rounded form. The Douglas-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.
Exposure Douglas-fir
The Douglas-fir should be grown in a bright place, with direct sunlight. The Douglas-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.
Watering Douglas-fir
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 Douglas-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 Douglas-fir
For these shrubs it’s necessary to choose a rich and deep substratum , which presents an excellent drainage.
