Thorny spruce in your garden

Thorny spruce in your garden

The main value of conifers is, of course, their beauty.

Lush pine branches, sparkling snow on blue spruce branches, slender thuja - all this can be a bright decoration of your garden plot.

Durability is one of the main features of conifers. Some specimens of pine, juniper yew live for several hundred years.

Today we will talk about thorny spruce trees, or the scientific Picea pungens.

The advantage of gray-colored spruces is their frost resistance. Thanks to the wax coating on the needles, it is resistant to adverse conditions.

Therefore, for gardening, instead of ordinary spruce, professionals advise for your garden prickly spruce "Glauka".

When choosing a coniferous plant for planting, it is very important to pay attention to the integrity of the earthen coma around the roots. The value of the safety of the coma is that special symbiont fungi live on the roots of conifers, which help the plants to feed. Without such symbiosis, the plant will not be able to grow and develop normally.

Important: do not buy a spruce tree with bare roots! If the soil around the roots has fallen off, do not let the root system dry out! Before planting, treat the root system of such a tree, in which a lump has collapsed, with a root formation stimulator (heteroauxin, root).

Colorado spruce, Picea pungens. Lives up to 100 years.

In culture, it grows up to 25 m in height, in natural conditions - up to 45 m.

It has a pyramidal crown with branches forming regular dense tiers around the trunk.

The needles are quite prickly, they are renewed every 3-5 years, new needles grow in the place of the fallen needles.

The color of the needles in prickly spruce is varied - green, blue, silver (gray).

Thorny spruce is photophilous, but it develops quite well in partial shade. He does not like waterlogging of the soil, as well as excessive feeding.

It is recommended to plant at some distance from roads, best of all - against the background of a lawn.

The most popular ornamental varieties of prickly spruce are: Glauca, Globosa, Argentea, Hoopsii.

Colorado spruce - planting and care

If you plan to plant several plants, consider the distance between the plants - at least 2-3 meters. Planting depth 50-70 cm. The diameter of the planting hole should be 40-60 cm larger than the diameter of the pot (container) in which the acquired spruce is located. At the bottom of the pit (with a layer of 20 cm) and in the gap between the earthen lump and the edges of the pit, a soil mixture is poured: 4 parts of garden soil, 2 parts of peat and 0.5 parts of sand.

It is not recommended to plant spruce in places with groundwater close to the surface.

Top dressing - one-time 100-150 g of nitroammofoska. Further feeding is not necessary.

Watering the plants is necessary in the summer, in dry hot weather - weekly, 8-10 liters per tree. At other times, you can water less often, especially since the thorny spruce, in contrast to the ordinary one, is more drought-resistant.

It is necessary to loosen the soil around the trunks of young plants, but to a depth of no more than 5-7 cm.

Young spruces in the first 2 years after planting must be mulched with a layer of 5-6 cm, i.e. cover the soil layer around the plant with peat or sawdust. After wintering, the peat is mixed with the ground.

Adult plants do not need to be mulched.

Important: for a favorable wintering, the needles of a young plant must be insulated with spruce branches (branches of conifers) or kraft paper (strong wrapping paper).
