\u00a0<\/strong>What is spring sunburn of conifers and why does it occur?<\/strong><\/p>\n

Spring sunburn of conifers is a non-infectious disease that occurs as a result of overheating and dehydration of needles under the influence of sunlight. Burns can be of varying severity: from mild yellowing to complete shedding and death of branches. Young plants, as well as those growing in open and windy places, are most susceptible to burns.The spring burn of conifers occurs because the needles continue to photosynthesise even in winter, when the roots freeze and are unable to provide sufficient water supply.When spring comes, the sun becomes brighter and warmer, and the snow reflects its rays, creating the effect of a magnifying glass. The needles become overheated and lose moisture, which it cannot replenish from the soil. As a result, a stressful situation arises, which leads to damage to the cells and tissues of the needles.<\/p>\n

How to identify spring sunburn of conifers?<\/strong><\/p>\n

\u00a0<\/strong>\u00a0The following signs can be used to identify spring sunburn of conifers: <\/strong><\/p>\n

– A change in the color of the needles from bright green to yellow, brown, red or purple. <\/strong>This indicates the accumulation of pigments in the needles that protect them from excess ultraviolet radiation.<\/p>\n

– Dry, brittle and falling needles.<\/strong> This indicates dehydration and necrosis of needle tissue.<\/p>\n

How to prevent spring sunburn in conifers?<\/strong><\/p>\n

\u00a0<\/strong>Spring sunburn of conifers can be prevented by following these rules:<\/strong><\/p>\n

Management of moisture levels:<\/strong> Adequate moisture is key to preventing spring sunburn. It is necessary to provide conifers with regular and abundant watering in autumn, before the onset of frost, when they accumulate moisture in the needles.Water conifers generously before the onset of winter to keep the soil moist. This pre-winter moisture helps the trees survive the dry winter months. Furthermore, watering during the winter thaw is essential, when the needles begin to evaporate moisture.<\/p>\n

Mulching:<\/strong> Apply a layer of mulch around the base of the tree to retain moisture in the soil and regulate temperature. Mulch acts as an insulator, protecting the roots from extreme temperature fluctuations.<\/p>\n

Windbreaks:<\/strong> Properly planted windbreaks can protect conifers from harsh winter winds, reducing the risk of drying out. This is especially important if conifers are planted in open areas.<\/p>\n

If you notice the first signs of sunburn on conifers growing in your garden, backyard or in the urban landscape area you are caring for, the best solution is to contact the specialists of the Green Clinic Centre for Ecosystem Phytopathology for professional advice.\u00a0 Always timely assistance for conifers and other plants by phone: +380632851405<\/strong><\/p>\n

If you implement these preventive measures, you can protect your conifers from the problems associated with the transition from winter to spring. Help conifers in the spring, when the period of active growth and regeneration begins, and make sure that your conifers are healthy, protected from disease all year round in an ever-changing natural landscape.<\/p>\n","protected":false},"excerpt":{"rendered":"
