Features of planting and care of pillow-shaped fir trees
Coniferous plants are increasingly choosing gardeners as accent elements of a personal plot. With them, the shape, texture, color of the garden, especially in winter, is effectively visible. A special role today in landscape design is played by a pillow-shaped spruce, the varieties and characteristics of which require more careful study.
Popular cushion varieties
Often near the houses you can see a dwarf blue spruce with a lush top in the form of a pillow. This dense cushion-shaped shrub is formed up to a maximum of 1.5 m high, spreads up to 2 m in width. Breeders have already bred more than a dozen varieties of dwarf spruce. All of them have a thick crown of silver-blue color.
It is worth listing the most popular varieties: Echiniformis (Canadian spruce), Waldbrunn (prickly), Pumila Glauka (ordinary), Tabuliformis. Of the standard varieties, the following should be distinguished: Machala, Blaukissen, Push.

- A wide range of applications. Look harmoniously combined with tall fir trees. Perfectly complement any rockery, rock garden, rock garden, terrace.
- Long preservation of the shape of the crown. Dwarf varieties can grow a maximum of 10 cm per year. This allows us to predict the final size of the plant.
- Minimal nursing activities. Low-growing fir trees do not need frequent haircuts, top dressing. They are rarely affected by diseases and pests.
Pillow-shaped spruce Nidiformis has a fluffy top shape, a hollow in the center, similar to a nest. An adult plant is formed up to 1 m in height and up to 2 m in width. At a ten-year-old tree, the height can reach 0.5 m, and the diameter of the crown is 1 m. This flattened shape is formed due to shoots growing in width. He has no main branches. The Nidiformis variety is characterized by a uniform, fan-shaped growth of branches, innumerable soft stems, short dark green needles (up to 10 mm).
Did you know? Needles of oil live about 7 years and gradually change. Every year, 1/7 of the needles fall.
In a year, it grows 3-4 cm in height and 6-8 cm to the sides. He does not like stagnant water, waterlogging. It is well accepted in sand-humus, sour, alkaline soil. The variety is sufficiently adapted to frost, only young shrubs need shelter in early spring. Initially grown in special containers, then used for planting in rock gardens, single and group mixborders.

All decorative blue and dark green spruce unpretentious, but still it is worth knowing some of the nuances of choosing a place and soil for them. The surface root system of the plant makes it unstable in the face of strong winds, which is important to consider. Dwarf conifers love well-lit places, in the shade they can lose the decorativeness of their needles. Also, in dark places they grow worse. If you need to select a site for a cushion-shaped coniferous bush, then stop at acidic or slightly acidic sites.
Important! Do not deepen the root neck of the shrub too deep into the soil. It is better to place it flush with the ground.
Loamy and sandy loamy soil will be optimal, where there is good air exchange, water permeability and a small amount of organic substances. Too loose or heavy soil must be mixed with the required amount of sand or clay. Carefully plant coniferous shrubs. It will affect their growth.
Follow these guidelines:
- Land in late April or August. In these months, plants are actively developing.
- You can plant young bushes from containers at any time of the year.
- Prepare a recess with dimensions of 40 × 60 cm. Make a gap between dwarf crops from 0.5 m to 1 m.
- Pour a layer of drainage material into the bottom of the well. For this, broken brick, soil from the forest, compost, humus are suitable.
- Set the roots of the conifer in the hole with the ground, gently sprinkle with soil, ram.
- Fix the young bush with support stakes.
- Pour the plant with slightly warm water, spread mulch around it.
Proper care of dwarf spruce trees allows you to grow beautiful “pillows”. The soil near the plant must be loosened regularly, especially in dry weather. This procedure inhibits evaporation, and the roots get enough air. You can mulch the soil with sawdust, needles, pine, tree bark.Mulch will save the bush from rotting of the roots and help maintain decorativeness for many years.
Watering and feeding
Adult plants are enough to water once every two weeks. Young specimens need to be properly moistened once a week. Any kind of dwarf spruce needs fertilizer. Complex means are suitable for them.
Did you know? Fir-trees do not bloom, but spring ovaries of cones. They are not considered fruits, but deformed shoots.
Mixtures with a low nitrogen content are best suited. You can use organic fertilizers: vermicompost, compost. Fertilizing with dolomite flour can bring benefits.
Trimming and Shaping
High varieties of Christmas trees are cut to restrain growth, but dwarf shrubs are used for decorative crown formation. In this case, you need to focus on the design of the bush. Mowing such low plants requires only minimal work.
The best time for this is to complete the growth of shoots. It is desirable to cut them to half, but to form the desired shape, you can completely remove it. Any haircut brings stress to the bush, it also makes it more resistant to diseases and pests.
If you decide to trim the pillow-shaped spruce, then be guided by the following important rules:
- Do not cut until the second year after planting.
- Avoid pruning more than 30% of green shoots.
- Do not leave bare branches; they may dry.
- Use a well-sharpened tool and wipe it after each shrub.

Use in landscape design
Pillow conifers have an unusual and dense crown shape. They are suitable for creating interesting and harmonious ensembles with exotic plants. This is a wonderful decorative edging of paths, paths in the garden, decoration of alpine slides. It is best to combine them with undersized bushes, with flowering or deciduous decorative perennials. Brightly flowering crops harmoniously frame the green needles of the Christmas trees.
From low conifers you can create a unique hedge. Blue varieties can be formed in the form of geometric shapes. Evergreen dwarf plants retain their decorative effect all year round. Looks impressive even a single landing. Sometimes they are used as a homogeneous carpet. Dense "pillows" planted close to each other resemble a green oasis in large areas.2-3 shrubs combined with a specific pattern look good. These compact cultures allow you to put them in the right place right in the container. They go well with squamous juniper. Growing dwarf spruce in your garden is not so difficult. It is frost-resistant, unpretentious, does not require special care. In a few years, the plant will become a real decoration of the site.
