How does the burn manifest?

In coniferous plants, a sign of solar burns is a fairly fast change in the color of the needles (from several days to 1.5 weeks), observed on the side of the crown, which is very illuminated by the sun. During the specified interval of the needle of the needle of natural color (green, blue or motley), it turns into a cloud or reddish-brown, and then yellowing, it becomes very fragile and usually subsequently - flies with the branches, barring them.

Shooting crown - burn sign

The causes of this phenomenon are considered:

• ultraviolet irradiation of needles from bright sunlight, reinforced reflection from snow;
• sharp daily temperature differences (most often - frosty nights and warm days);
• dehydration of needles.

Be carefull!

Sometimes one more is added to these reasons - this is a violation of metabolic processes between individual parts of the plant, when the shoots have already come to life, and the roots are still at rest, "sleep".

Who is in the risk zone?

They suffer from solar spring burns most often young, faster plants, as well as copies planted in a bright sunny location with a vertically growing form of crown (conical, pyramidal, column-like). Plants of raw forms in the risk group do not fall.

In the risk area - plants with a column-shaped crown

Among the conifers can especially suffer from sunburns:

• fir Canadian Conica, Sander'sblue, J.W. Daisy's White,
• young seedlings were ate of ordinary Acrocona,
• plants of some varieties ate ordinary and fir Serbian,
• plants of some varieties of the pine of the husto-flowering,
• young Plants Fir Korean and Single Ficht,
• plants of some varieties of juniper ordinary
• juniper Chinese Stricta and Stricta Variegata,
• plants of a number of varieties of Lavson cypressov
• plants of some grades of berry and tsi western.

Moreover:

Light sunny burns are possible on young sheds of ordinary pine, pine black pyramidalis and plants of some varieties of Tui Canadian.

How to protect the plants from sunburn?

• First of all, it is worth paying particular attention to the preparation of plants by winter. Since the fall, the conifers need to be actively "shed" to create a supply of moisture in their soil coma to prevent sunburns. Watering plants you need once a week, not ice water. Watering is carried out slowly (so that water is absorbed into the soil, and not glass from it), at the rate of no more than 15 liters per square meter.
• In addition, plants will need to be covered. If you do not plan to come in winter to your site, then it will be necessary to cover the plants from autumn. It is best to use shelter with frameworks. The frame can be made or purchased in stores for gardeners. Wooden or wire (from a wire mesh) The frame is mounted on the ground, along the perimeter of the plant, the crucible material is stretched on the frame. As a passing material, it is better to use burlap (including rare burlap) or a dense gauze to protect against sunburn. If you are constantly living next to the landings, you can start protecting plants from the sun directly in February (by weather). In this case, close to the plants can be installed not framework, but reflective screens (in shape resembling easels), which is also stretched by observer material (burlap, gauze, spunbond). Some gardeners simply have a cardboard sheets near the plants. Screens or cardboard, naturally, are installed on the side of the crown of the plant, which is most highlighted by the sun. We clarify immediately - the screens protect the plants only from solar burns, the framework of the same shelter - and from frost, and from solar burns.
