As you put up the Christmas decorations, have you ever wondered what a Fir tree is? Any child can draw one, but what makes it a Fir? Lots of trees are called…
Pseudotsuga genus (Douglas fir). Conifers are distinguished from other trees and shrubs by producing seeds which are exposed on the scales of woody fruits called cones and needle-like leaves. The leaves are arranged radially on the shoots, developing from pointed many scaled buds that are distinctive to this genus. They can be grown in any well drained, non-chalky soil in full sun. Remember however that they can grow to enormous sizes.

These are frost-hardy trees and prefer cold climates with cool, deep soil and sunny, open spaces. You can propagate from seed or by grafting. If the conifer produces more than one leader, to maintain the general conical habit remove all but one leader. To restrict the height of the plant, the leader can be cut back.
Seed sown in autumn or spring (but forms selected for leaf colour do not come true). Evergreen current growth cuttings in autumn to spring. Deciduous softwood cuttings in summer.
Honey fungus may be a problem, although this genus is fairly resistant.
