Weigela - a shrub plant from the family Honeysuckle (Сarrifoliaceae) needs proper care not only throughout the spring-summer period, but also in autumn.
General principles for the care of Weigel autumn
After flowering, in the autumn period, seed material massively ripens on the ornamental shrub, which can be collected around November. It is at the end of autumn that the seed bolls fully ripen and as a result begin to crack. It should be remembered that plants grown from seeds almost never retain varietal traits of the parent culture.
If there is no need to collect seed material, then in order to prevent self-seeding and clogging of the site, it is advisable to timely cut the crown of a garden plant. During this period, damaged, dying or diseased branches are removed. Trimming is performed using a clean and sharp pruner, without fail oblique cut. It is necessary to ensure that the buds remain on the shoots. Too old and completely dried branches are cut almost at the ground itself, at a height of no more than 5-10 cm from the ground level. It is necessary not to start free growth, and to control the condition of the aerial parts of the ornamental shrub.
Autumn dressing garden wigel
The decorative shrub needs nutrients not only at the stage of active vegetation, but also in preparation for the winter period. If a the first feeding is done in the early spring using full mineral fertilizer, the second application of nutrients must be performed in late May or early June, when the process of forming flower buds is actively ongoing.
During this period, it is recommended to introduce simple or double superphosphate, as well as potassium sulfate. Phosphate fertilizers, introduced before flowering, makes flowering plentiful and long, and with the help of potassium, branches are strengthened, and preparation for winter cold occurs.
For a good wintering, special attention should be paid to the third top dressing, which is done in the autumn period. In preparation for the winter, digging requires potash fertilizers. Fertilizer "Kemira Autumn" has proven itself very well, but you can also use sulfate or potassium chloride, as well as ordinary wood ash, made at the rate of 400 gr. a couple of square meters of landing area.
How to prune a weigel after flowering
Preparing Weigels for Winter with Shelter
Preparing for winter is a whole range of activities that includes arranging a high-quality and reliable shelter that will prevent the plant from freezing. After all the foliage has completely fallen from the ornamental shrub, and this situation is observed in the last decade of October or at the very beginning of November, it is required to provide the plant with high-quality and reliable protection against approaching frosts. For this purpose, experienced gardeners recommend using ordinary soil. It is necessary to sprinkle near-trunk circles of shrubs with earth, with the formation of a soil mound about a quarter meter high.
The aerial part of the weigel should be carefully bent to the ground and pressed or fixed with rope loops. Above the bent branches, a shelter from a traditional roofing material or a garden spunbond is arranged. So that the shelter does not disrupt by gusts of wind, it must be fixed with heavy objects or stones.
Many gardeners don’t bend the branches of the bush to the ground, they simply tighten them tightly using twine or kapron rope, after which the decorative bush is enclosed by a frame structure based on a plastic or metal mesh. Inside such a structure, a thermal layer is poured, which can be used as dry fallen foliage. Outside, the protective structure made is wrapped in dense but breathable covering materials.
Weigel grafting technology in autumn
Vegetative propagation by cuttings is a simple and absolutely affordable way to obtain a beautifully flowering ornamental shrub. Cuttings 10-15 cm long are cut with a sharp knife. It is advisable to completely remove leaves from chopped cuttings or leave no more than a third of the leaf on top.
Cuttings are carried out in cloudy weather, which will reduce the risk of excessive evaporation of moisture from the stem part. Slices are made at right angles.and then soaked for a couple of hours in ordinary clean water, after which they are necessarily treated with any growth stimulant. The processing of chopped cuttings “Kornevin”, “Heteroauxin” and “Epin” for twelve hours in a dark place is best proven.
After processing with growth stimulants, harvested cuttings are planted in a peat-sand mixture, where the process of subsequent rooting takes place. Cuttings are planted at an angle, with a depth of a couple of centimeters. Landing must be covered with plastic wrap, which will allow you to get a greenhouse effect favorable for rooting the plant. Landings must be provided with daily airing and irrigation measures that ensure optimal microclimate. Artificial fog effect is best suited for growing crops.
With the proper implementation of the cuttings and high-quality subsequent care of the cuttings, the process of developing a good root system takes about one month. Important to remember, that in order to obtain a decorative culture with an attractive crown shape and size, as well as to stimulate tillering, at first all shoots growing from the cuttings are removed. Young ornamental plants should be transplanted to a permanent place in the open ground no earlier than a year and a half after the cuttings are completed. Such bushes bloom in a couple of years.
How to plant Weigela in the fall
What is important to know about the autumn Weigela planting
A decorative shrub planted in the spring, in the period from soil warming up to swelling of the buds, is best established. Seedlings planted in the fall, most often die in the first winter, due to the botanical features of the thermophilic ornamental plant. For landing, you need to choose a place on a hillprotected from the northern cold wind and strong drafts that cause the shedding of flowers and buds.
Ideally suited for planting and growing the south side of the house with good sunlight. To obtain abundant and prolonged flowering, the soil on the site must be loose and rich in humus. Preference should be given to sandy or loamy soils having a slightly alkaline or neutral reaction. Important to remember, that only plants no younger than three to four years old are suitable for planting.
Before planting seedlings, in pre-prepared landing holes, it is required to lay quality drainage. Optimal for landing are pits with dimensions of 50x50 cm and with a depth of approximately 35-40 cm depth. Brick fight or gravel 15 cm high is laid at the bottom. Garden soil with 40 g of potassium salt and 60 g of superphosphate is used to fill the holes. Trunk circles of the planted plants are mulched with shredded bark or sawdust. The decorative culture planted in this way quickly takes root and pleases with abundant flowering.
