What are the propagation methods for the pink-purple double-petaled rose of Sharon?
The pink-purple double-petaled rose of Sharon has strong adaptability, and cultivation by hand is not difficult; it is grown throughout both northern and southern parts of our country. Artificial propagation of the pink-purple double-petaled rose of Sharon can be done by division, cuttings, sowing and layering.
Pink-purple double-petaled rose of Sharon
I. Division propagation
Before sprouting in early spring, dig up vigorous mature clumps, take 3 main branches as 1 clump, and plant them at a plant and row spacing of 50×60cm.
II. Cutting propagation
Cuttings can be taken from mid-March to early April in combination with pruning and shaping; select lignified, vigorous branches for the cuttings, 10-12 cm long, and insert them outdoors in red soil or sandy soil, keeping the soil moist, but the survival rate is relatively low; it is best to insert them in a seedbed kept moist with plastic film, where at a temperature of 17°C to 20°C they root very easily.
Choose vigorous, un-sprouted branches 1-2 years old. Cut them into small sections 15-20cm long; when taking cuttings, prepare a small stick, poke small holes in the seedbed at the plant and row spacing, then insert the pink-purple double-petaled rose of Sharon branches, firm the soil, with a planting depth of 10-15cm, that is, a planting depth reaching 2/3 of the cutting is suitable, and water thoroughly immediately after insertion. No base fertilizer needs to be applied when taking cuttings.
III. Seed propagation
Generally carried out in April in spring. After the fruit matures in October, collecting seed in November-December is most suitable; after harvesting, shell out the seeds and store them dry at low temperature, then drill-sow or broadcast-sow in April of the following spring. For division propagation, after leaf fall in autumn or before sprouting in early spring, dig up the suckers at the root zone of the plant and plant them separately. Before planting, the roots can be pruned appropriately, and the above-ground part should be heavily cut back. The pink-purple double-petaled rose of Sharon has strong adaptability, is simple to cultivate and requires extensive management, and generally can be left to grow freely. However, to improve its ornamental effect and make its flowers abundant and brightly colored, necessary management should be given. The pink-purple double-petaled rose of Sharon blooms on new growth of the current year, and appropriate pruning can be carried out after leaf fall in autumn. When pruning, thinning and cutting back should be combined; long branches should be cut back appropriately, and overly dense and thin weak branches should be thinned out, so that nutrients are concentrated and the plant is full. In mid-to-late April after the plant sprouts in spring, fertilizer should be applied once, and watering should be done in real time to ensure sufficient fertilizer and water in the soil. When the pink-purple double-petaled rose of Sharon is planted out, base fertilizer should be applied in the planting hole, and thereafter generally no more fertilizer is applied. From before the buds sprout in spring to the flowering period in summer, water 2-3 times depending on the weather. In the rainy season, drain water and prevent waterlogging. After autumn, before frost, water once thoroughly to prevent freezing. In late summer and early autumn, watering is not suitable, so as to avoid the autumn shoots growing too tender and reducing cold resistance. When nursery stock below 5-6 years old overwinters, cold protection measures should be taken, such as mounding soil around the roots.
IV. Layering propagation technique
Because the branches of the rose of Sharon root very easily, before sprouting in spring dig a shallow trench beside the mother plant, lay 1-year-old branches horizontally into the small trench, cover with soil, keep the soil in the layering trench moist, and they will soon root and send out shoots. After leaf fall in autumn, cut the layer off from the base, then dig out the nursery stock and divide it into seedlings.
Pink-purple double-petaled rose of Sharon cultivation methods. Is the pink-purple double-petaled rose of Sharon toxic?
The pink-purple double-petaled rose of Sharon grows fast and has strong adaptability, and is cultivated in both northern and southern parts. The pink-purple double-petaled rose of Sharon has a very strong air-purifying ability, so how is the pink-purple double-petaled rose of Sharon cultivated?

I. Cultivation methods for the pink-purple double-petaled rose of Sharon
The pink-purple double-petaled rose of Sharon can be cultivated in single-row ridge planting, with a ridge spacing of 110-120 cm and a plant spacing of 50-60 cm, and planting holes or planting trenches opened in the middle of the ridge. When transplanting and planting out the rose of Sharon, sufficient base fertilizer should be applied in the planting holes or planting trenches, generally mainly farmyard manure such as garbage soil or rotted stable manure, together with a small amount of compound fertilizer; transplanting and planting out is best done during the dormancy period of the seedlings, and can also be done in the rainy growing season. When transplanting, part of the branches and leaves should be cut off to help survival; after planting out, water once with settling water and keep the soil moist until survival.
During the growth period there are relatively few pests and diseases; the main diseases are anthracnose, leaf blight, powdery mildew, etc., and the main pests are red spider mites, aphids, bagworms, noctuid moths, longhorn beetles, etc. When pests and diseases occur, the diseased and pest-infested branches can be cut off, and safe, efficient, low-toxicity pesticides can be selected for spray control or trap killing. Attention should be paid to early control, and applying pesticide during the flowering and harvesting period should be avoided, to ensure that the harvested rose of Sharon flowers are not contaminated by pesticide.
Common leaf spot and rust are harmful; spray with 65% zineb wettable powder at 600 times dilution. Pests also include whiteflies and scarab beetles, mainly aphids, as well as inchworms and leaf-rolling moths, which can be killed by spraying with 40% omethoate emulsifiable concentrate at 1000 times dilution. An environmentally safe insect-killing method is diluted detergent.
