The aforementioned setting of strong shoots is the main reason why it is best to trim the lilacs within a week or so after all the inflorescences have faded. Trim each shoot under the flowers to leave two pairs of he althy buds on it.After cutting the bush, we feed the bush with fertilizer and water it abundantly so that the plant can sprout new, strong shoots.
Flower buds rarely form on thin twigs. Older shrubs or trees with thinning inside crowns can be heavily trimmed right after flowering. Such a procedure will maintain their flowering strength.
Every 3-4 years we use a sharp pruner to completely cut out some old and thick shoots.To grow a lilac in the form of a tree, buy a young bush and systematically remove side shoots from the main stem of the trunk.Not many lilacs are grafted today.
Most varieties come from laboratories where seedlings with closed buds are stimulated to grow with the help of hormones. In this way, without genetic combinations and crosses, we get a new plant. Such lilacs can grow as shrubs with many shoots.
Ways to cut the most popular shrubs
Their outgrowths have features identical to the parent variety.If a specimen of a grafted lilac grows in the garden, the wild shoots that appear in the garden should be cut regularly close to the ground.They should be treated as parasites, because they take away the noble variety of strength and develop other, less showy flowers.
Be careful when working in the garden. Shallow-growing lilac roots can be easily damaged with a spade, which stimulates the plant to strongly release wild root suckers.
