Blue spruce trees are real queens of landscape design. These pretty trees look great in any part of the summer cottage, and at the entrance, and on the outskirts. But in order to grow them really beautiful and decorative look, it is necessary to provide quality care for blue spruce.
Earlier I talked about how to grow blue spruce from seeds. This activity is painstaking, but very interesting, because the result speaks for itself. But in order to get really decorative trees in a few years, planting fir trees and waiting for their sprouts is not enough, it is important to study agricultural technology and learn how to properly care for blue fir trees.
Today we will tell you how to ensure the best conditions and what needs to be done so that the trees in the country are a real decoration, and not like an ordinary shoot.
Watering a blue spruce
Initially, we want to warn that caring for a small spruce up to several years old is exactly the same as for sprouting, but then some of the principles of cultivation may change, so be careful.
Watering one-year-old seedlings will require a lot of free time, since water should be introduced into the soil 5-7 times a day in small portions so that the soil does not dry out and the roots of the young tree always have the possibility of recharge. Large portions of water are not needed, as in fir trees at this age, the roots are almost on the surface itself, and overflowing in this case will simply be inappropriate.
Older trees, at the age of several years and older, are watered much less frequently, about 1-2 times a day (and someone once every few days). It will also be necessary to constantly monitor the moisture of the soil, for which it will be necessary to mulch the trunk circles or plant thick grass in them. I like blue fir trees and spraying, sprinkling with warm water. Due to this, the greens are moistened and washed from dust.
When the seedling begins to grow into an adult tree, try to provide him with decent watering. It is undesirable to spare water for this plant, and therefore if drip irrigation of beds or irrigation of lawns is organized at the cottage, take care of the Christmas trees, throw a hose with water at their foot.
But it is worth saying that it is not worth worrying about. After conferring with our readers and specialists in the cultivation of spruce, we came to the conclusion that an adult tree calmly withstands in the summer up to 1-2 weeks without watering at all, but this is if there is no drought!
Nutrition for blue spruce
There is a lot of debate about this, and in order to achieve the truth, we specially had long conversations with summer residents and owners of some nurseries, and even read forums where the owners of the Christmas trees share their opinions and experiences.
As it turned out, many generally refuse to feed the plant, although they recognize that up to 5-7 years the plant practically does not grow. You can, of course, use growth stimulants and some fertilizers, but then you can achieve the effect of a real forest tree in your country house, and this is certainly not interesting to anyone.
After 5-7 years of cultivation, the blue spruce gradually grows, and in the next few years it freely picks 30-40 cm, and sometimes 50-70 cm per year. If you do not overfeed the tree, then literally for several years the growth of the tree stops, and a nice tree flaunts on the site, which is truly decorative!
There is also an opinion that top dressing is harmful to spruce, and because of them one can observe a certain type of mutation, when, for example, the side branches turn into stem branches, and then the tree grows not up, but to the side. It is also worth noting that it is not recommended to apply top dressing in the fall, otherwise the tree may not survive the winter. If you use fertilizers, then this should be done in spring and early summer, in small portions!
It is strictly forbidden to make nitrogen fertilizers and manure, which do not positively affect the plant. But you can use universal fertilizers in small quantities.
Trimming and shaping the crown of blue spruce
Blue spruce does not need systematic pruning, as the crown of the tree is formed independently. But it is worth paying attention to the plant at least several times a year, as it should be removed from the trunk of the diseased and broken branches, dry and yellow, which adversely affect the development and decorativeness!
Also, if there is a desire to independently form a crown and control the growth of spruce, you can do this, but preferably up to the age of 7-8 years. After, it is better to leave the blue spruce alone and let it develop further completely completely on its own.
Breeding and propagation of blue spruce
We want to remind you right away that for planting young spruce seedlings or seeds, you can’t use the soil where potatoes and corn, as well as other garden crops that were badly damaged by the fungus, used to grow. Be sure to add when planting forest land, which is taken from under conifers, this will give a huge plus in development.
Propagated blue spruce seeds, grafting and grafting. We already considered the first method earlier, when we talked about growing blue spruce from seeds with our own hands, and therefore we will skip it and move on to others.
So, the vaccine ate. Quite an easy way, but few have been using it recently. The spruce is grafted into the cleavage of the shoot (apical) or butt. The process is preferably carried out at a favorable time - in the spring, or in the first decade of July.
With cuttings, everything is more interesting, and faster! Cuttings of blue spruce are cut from a more or less mature tree, and rooted in a greenhouse with high humidity, which can be created and maintained artificially. It will be even better if fogging equipment is installed in a greenhouse or greenhouse, this will only benefit.
Experts recommend propagation by winter cuttings, in early spring, when kidney swelling occurs. Summer cuttings are also suitable for this, but their rooting takes much longer, 3-4 times. Usually, when creating the most favorable conditions, it takes up to 3 months to root a blue spruce.
Diseases and Pests
Like any coniferous plant, our blue Christmas tree is subject to multiple dangers, from which it can not only suffer in the decorative plan, but eventually die at all. We will not go into details and talk about diseases and pests, since we already have the necessary material about diseases of conifers!
What you should know about caring for blue spruce
In the last section of our article, we would like to say something else useful:
- Blue spruce is highly decorative. This is a shade-tolerant plant that is not afraid of frost and drought (although it likes timely watering more);
- The tree is characterized by slow growth, but does not require multiple fertilizers, except in spring and in small quantities;
- A rich and moist soil is necessary for planting, since spruce grows poorly on calcareous and dry soils;
- Young plants may suffer from late frosts;
- Most quickly, trees propagate by cuttings, but subject to certain conditions;
- Beautiful decorative plants like spraying, and they become much more beautiful after sprinkling.
Vaccination of spruce (video)
Just a few facts about blue spruce and the proper care of an ornamental plant, and it’s already much easier to grow a nice tree in a summer cottage. We can only rejoice at the people who planted Christmas trees in the country for a long time and were able to grow strong trees from them, as well as recommend faster to start growing fir trees for summer residents who have not done so!
