About this plant
This makes a tree of moderate size, reaching up to 15 or more metres in optimum conditions but often far less. It is native to western parts of North America and northern Mexico. It can be found at altitudes of 3,800 metres, but is a dwarf at that altitude. There are specimens that have reached an age of 2,000 years. It is a characterful plant that will develop a thick trunk with long grey branches that carry tussocks of long needles which are flexible - hence its name. The needles are coloured blue-green. There are yellow pollen-cones followed by smallish fir-cones which occur as single specimens. They are coloured grey brown. The fir-cones carry resin. This tree does not have commercial value but is highly picturesque. It looks somewhat like Pinus aristata which also has a similar range and grows at altitude.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
