Answers to common questions about plant care, landscape design, greening, and drip irrigation from Maghakyan Botanic in Armenia.
Winter care is important because plants face several challenges during winter: low temperatures, limited light, dry air, and wind. Special care helps plants withstand these conditions, protecting them from freezing, dehydration, and diseases, ensuring their survival until spring.
To protect outdoor plants from frost, you can use mulching (e.g., straw, leaves, tree bark) around the roots, which will insulate the soil. Small plants can be covered with agrofabric, burlap, or special protective covers. In some cases, heating cables are also used.
Yes, though less frequently. If winter is dry and snowless, especially before frosts, it's necessary to water plants moderately to prevent roots from drying out. This is particularly important for newly planted trees and shrubs. However, avoid overwatering to prevent root rot.
For houseplants in winter, it's necessary to reduce watering and fertilization as they are dormant. Provide sufficient light (possibly supplemental lighting), and increase air humidity (e.g., with humidifiers or water trays), as heating systems dry out the air. Keep plants away from heating appliances.
Generally, no. Most plants are in a dormant or slow-growth state during winter, and fertilizers can harm their roots. Start fertilizing only in spring, as active growth begins.
Evergreen plants, such as conifers, can suffer from winter sun and wind, leading to dehydration. To protect them, you can use burlap or netting to shield them from direct sunlight and drying winds. It is also important to water them well in autumn before the ground freezes.
Winter is often a good time for pruning dormant trees and shrubs, when leaves have fallen and the branch structure is easy to see. This helps the plant focus energy on healthy growth in spring. However, avoid pruning flowering shrubs that bloom on old wood (e.g., forsythia).
To protect roses in winter, mound soil or compost around the base (to a height of 20−30 cm). Stems can be wrapped in burlap or special winter covers. In some cases, wire mesh cages filled with dry leaves are also used.
Winter lawn care includes autumn fertilization (with fertilizers rich in potassium and phosphorus), a final mow before frosts so the grass isn't too long, and leaf removal. In winter, avoid walking on the lawn when it's frozen or covered with snow to prevent damaging the turf.
In winter, it is necessary to completely drain the irrigation system (pipes, pumps, faucets) of water to prevent them from freezing and getting damaged. This includes clearing out sprinklers and drip systems.
Young trees are particularly vulnerable to cold and rodents. To protect the base of the trunk, use tree guards or netting to guard against rodents and sunscald. You can also whitewash the lower part of the trunk to prevent sun damage and bark cracks.
Heavy, wet snow can break branches, especially on conifers and shrubs. If too much snow has accumulated, gently shake it off the branches with a stick or your hand. However, generally, snow is a good insulator, so only intervene in cases of heavy accumulation.
The best way to protect the root system is through mulching. Apply a thick layer (10-15 cm) of straw, leaves, tree bark, or compost around the base of the plant. This will help maintain a stable soil temperature and prevent roots from freezing.
Dormancy is a period of suspended active growth in plants in response to unfavorable conditions (cold, drought). During this time, the plant's metabolism slows down, and it conserves energy. Proper winter care helps plants safely navigate this period.
Greenhouses and cold frames should be cleared of all plant debris in winter to prevent the spread of diseases and pests. Check the structural integrity and repair any damage. You may also need additional heating or insulation if you plan to grow plants during the cold season.
Some plants, especially those of tropical origin, do not go dormant in winter. For them, you need to provide stable temperatures, sufficient light (often with supplemental lighting), and high humidity. Watering and fertilization schedules are maintained according to their growth rate, rather than the season.
Rodents can damage the bark of trees and shrubs in winter. To protect them, clear the area of weeds and plant debris to reduce hiding spots. You can use wire mesh or plastic tree guards to protect tree trunks. If necessary, traps or baits can also be used.
Low-growing plants, such as alpine plants or some small shrubs, can suffer from ice formation when a layer of snow and ice covers them. This can lead to suffocation or diseases. To avoid this, you can lightly cover the plants with spruce branches or heap snow around them so that the ice layer does not stick directly to the plant. And in cases of temperature fluctuations, it is necessary to ensure proper drainage to prevent waterlogging.
