Planting and caring for spruce Canadian Sanders Blue

Do not allow soil compaction and moisture stagnation. The landing site should be away from groundwater. It is imperative to make a drainage layer, in the form of sand or broken brick, 15-20 cm thick. If spruce trees are planted in groups, then the distance for tall spruce trees should be from 2 to 3 m. The depth of the planting hole is 50-70 cm.

It is important that the root collar is at ground level. You can prepare a special soil mixture: leaf and turf soil, peat, and sand in a ratio of 2:2:1:1. Immediately after planting, the tree must be watered generously with 40 - 50 liters of water. It is advisable to apply fertilizer (100-150 g of nitroammophosphate, 10 g of root per 10 l, etc.).

Spruce trees do not like dry, hot weather, so during the hot season they need to be watered once a week, approximately 10-12 liters per tree. Carry out shallow loosening (5cm). For the winter, sprinkle peat around the trunk with a thickness of 5-6 cm; after winter, the peat is simply mixed with the ground, not removed. Spruce trees can also be planted in winter.

Approximately 2 times a season you can apply fertilizer for coniferous plants.

Spruce trees usually do not need pruning, but if they form hedge pruning is allowed. As a rule, diseased and dry branches are removed. It is best to carry out pruning in late May - early June, when the period of active sap flow ends.

To protect the decorative forms of spruce from autumn and winter frosts, they can be covered with spruce branches. (cm.

Methods of propagation of Canadian spruce

There are two main ways to propagate Canadian spruce - propagation by seeds and cuttings. Any of these methods is a rather labor-intensive and time-consuming process, since growing a Canadian spruce seedling is very difficult. It takes a lot of time and requires constant attention and care.

Propagation by seeds

This method is very difficult to use at home, since you will have to wait a very long time for the results. First you need to prepare the seeds. You need to take fresh ones - they will take root better. Seeds are collected from unopened cones. Then the best ones are selected and stratified. To do this, planting material can be placed in a mixture of sand and peat and refrigerated for 4-6 weeks.

After cold hardening, the container with the seeds is placed in a warm and bright place and watered abundantly. The best time for germination is late winter or early spring. When watering, be sure not to overwater the sprouts, otherwise they may begin to rot. Canadian spruce is planted in open ground only in the second year.

Reproduction by cuttings

Growing Canadian spruce from cuttings is also a lengthy process, but it is more reliable and gives good results. The best time to start rooting cuttings is June, as they have time to get stronger before winter. At this time, calluses appear on the cuttings, and the first roots appear from it only the next year.

For cuttings you need to choose the right branches. Usually the mature branches at the very bottom are torn off from the mother tree. Their height should be approximately 10-12 cm.
It is necessary to separate the cuttings correctly - make sure that the branch must have a “heel”, with a part of the mother tree. Without her young plant won't take root.
Next, you can treat the planting material with growth stimulants, for example “Kornevin”. To do this, pour the solution into a jar and lower the cuttings there by 2 cm. You can keep them in the solution for 2 hours. After this, this solution can be diluted in water and used to water the cuttings.
A mixture of peat and sand can be used as soil.
The cuttings are buried into the prepared substrate by about 2-2.5 cm and covered with film, having previously been sprinkled with water. This must be done to maintain the required humidity.
Be sure to monitor the soil moisture, it should not dry out.
It may take 4-5 years to obtain a finished seedling.

How to plant a spruce with a closed root system. How to plant blue (Canadian) “Sanders Blue”

Upon landing coniferous plant carefully remove it from the container.
If you have heavy chernozem or loamy soils, it is better to first cultivate it with the addition of sand and peat (or pine shavings, fine bark or litter). The soil must be made “light” and air- and water-permeable. If the site does not have at least a minimum slope, you should drainage system coniferous planting sites.
There is no need to dig large holes in heavy soils and lay drainage on the bottom - they will serve as accumulators of water from the site. It is better to arrange a slight slope of the site so that the water does not linger on rainy days.
If you have sandy loam soils, you're in luck. There is no need to do anything additional.
In the prepared soil, a hole is dug to the size of the pot (coma) and after establishing earthen coma coniferous plant in the planting hole, the air gaps are filled with soil for backfilling, trying to fill all the voids. It is very important not to bury root collar plants, it should be slightly above ground level, otherwise the plant may die. After planting, it is necessary to water the plant abundantly.

Reproduction

Propagated by cuttings, which is best done in early June. Winter cuttings do not take root without treatment with a rooter. To take cuttings from the mother plant, it is necessary to take mature lower branches, which do not exceed 10-12 cm in size. The cutting to be separated from the mother plant must have a “heel”, otherwise the plant will quickly die. The lower part of the harvested cuttings must be treated with growth stimulants. The cuttings are planted to a depth of 2-2.5 cm. The substrate should not dry out as the plants take root, but it is not recommended to over-moisten the soil.

Growing and caring for spruce

Light-loving, but tolerates light partial shade. Loves moist and fertile soil, light or medium loamy. Upper layer the soil must be well permeable so that the roots receive required amount air supply. Does not tolerate waterlogging and soil compaction. Undemanding to moisture. Smoke and gas resistance is average. Wind resistant. It is recommended to periodically weed and loosen the circle around the trunk, but do not dig it up. It is also advisable to mulch the tree trunk circle with peat or loose compost and then seal it. During dry periods, regular watering is recommended, preventing the root layer of soil from completely drying out, as well as evening sprinkling of the crown.
