Hur man planterar dormancy

Whip-and-tongue , cleft , side-stub and other grafts must be done when the rootstock is dormant. This is because the scion has to live on its own until the graft union forms to unite it to the rootstock. An actively growing scion would use its small reserves of water and sugar before the union formed and would die. Spring and winter-blooming shrubs and trees should be pruned after their bloom cycle is done.

Often not just the scion, but the rootstock too must be dormant. Pruning can also affect blooms. While nearly all plants go dormant in winter, dormancy can also happen during times of stress—such as extreme heat or drought—when a plant might shed its leaves in order to conserve what little moisture may be available to it.

Summer and fall blooming shrubs usually bloom on new wood formed in spring although it varies, as with hydrangeas. When grafting woody plants, the scion wood must be dormant. Seeds too can be dormant: a seed is dormant until it begins to germinate and grow into a new plant. If you lived in a temperate forest, what would happen when the freezing, dry winter months came? You would run out of energy, or food, or water, or your body would be destroyed by the environment.

These buds are dormant because higher up parts of the plant are telling them to stay dormant, using chemical signals.

Dormancy is a kind of armored sleep that plants go through. Knowing when to prune is important for the health of a plant. Some grafts can only be done during dormancy; some only during active growth. Prune these plants when dormant. Because pruning can stimulate new growth that can be damaged in late fall or early winter freezes, wait until late winter when the plant is fully dormant.

By Jonathan Landsman Jonathan Landsman. It is in a waiting state, a kind of suspension of life until conditions are right for active growth. What if you were rooted to one place out in the wild? Life would be fine in the rainy spring and milder days of summer.

A scion is a small piece of plant that has no roots, no way to feed itself. Much pruning is meant to break dormancy or to control unwanted breaks in dormancy. The idea is to catch the stock at that time shortly before spring when it contains a high reserve of sugars and no growth of its own drawing off these sugars.

An entire plant can be said to be dormant, as is the case of deciduous plants in winter. Buds can be dormant for another reason; if you look at the upper nodes of a woody plant , you will probably see buds, even in the middle summer when the rest of the plant is actively growing. Dormancy is a period where plants save energy.

This is how we can prune without permanently damaging a plant, and why we use pruning to make plants fuller or change the direction of their growth.

When we prune off the plant above the dormant bud we interrupt these chemical signals.

When spring comes, the stock will send its sugars upwards in support of active growing—most importantly at the graft site, where healing and union can then rapidly occur.

Lower parts of a plant, such as the thick trunk of a tree or even the older branches, have dormant buds too, but these buds are buried within layers of wood and invisible. They also shed a mantle of soft leaves and stems for something akin to a suit of armor: hardwood, scales, and other dried dead tissues much like the leathery dead skin of our own epidermis think of a foot callous.
