When the hedge becomes too large, it is run down, weeded or very thin at the base, decisive action is needed. Hedge plants resistant to pruning, such as holly, hawthorn, buk, ognik or yew (the only coniferous plant, which tolerates intensive pruning well), we can shorten them strongly to rejuvenate them and give them a new form. We perform this treatment in early spring. Young shoots appear relatively quickly, thanks to which the appearance of the hedge significantly improves during the same growing season. Please note, to apply fertilization in the year preceding the treatment, so that the plants are healthy and respond well to the rejuvenating cut.
A sharp cut is a drastic procedure, therefore it should be done in two steps. As a rule, first trim the hedge in height and one of the sides, and in the following year, the other side. If the plants do not take pruning well in the first year, We wait for two growing seasons with the formation of the other side.
Before proceeding with the procedure, it is necessary to check, or tools – saws, secateurs and shears – they are appropriately sharp. We work in protective gloves and glasses. Start trimming from the bottom. Well, if we have a grinder and we have a person to help, which cut branches are shredded on a regular basis.
Trim the top of the hedge last. The first effect shouldn't scare us. Let's enjoy the thought, that after such a slaughter the plants can recover! After the treatment, we use a long-acting fertilizer, mulching with mature organic material and watering the plants abundantly.
Leyland's Cypress hedge.
Choosing Leyland's Cypress Tree (x Cupressocyparis leylandii) on a hedge plant, Let's think carefully about this decision. It is not an easy plant to care for. The cypress tree grows fast (about 100 cm during the year) and trimmed regularly – which, with such a large annual increase, also means very often – forms a magnificent hedge. Left on its own, it instantly becomes a problem – it sterilizes the soil and shades a large area of the garden. To avoid problems in the future, We shape the hedge properly from the beginning. In the first year, we should trim the side shoots, giving the plants the desired shape. We cut twice: in mid spring and again in mid summer. When the main shoot reaches the intended height, we trim it by approx 15 cm. If the young plants grow too much, in mid-summer we can shorten them by a maximum of one third. Trim the side shoots very carefully, because the shortened perennial shoots will not grow back.
Rejuvenating a hedge by "laying" (ang. laying) is the art of former English gardening, which in the British Isles has almost completely disappeared for many years, and is now beginning to experience a real renaissance. Laying a hedge, because that's what we're talking about, it consists in trimming old shoots right at the base and tilting them (position) at an angle from 0 up to 45 ° along the hedge line. The right incision – about three-quarters of the diameter of the shoot – stimulates the formation of regrowths. Young shoots growing back at the base alternate with bent old ones, creating a green thicket impassable. Hawthorn hedges have been rejuvenated in England since time immemorial, hazel and field maple.
