A detailed introduction to the propagation, pest and disease control, and cultivation techniques of Weigela florida 'Red Prince':
Selection of cutting orchard and seedbed nursery sites
Choose soil with a loose texture, fertile, slightly acidic, neutral and slightly alkaline, for building the cutting orchard and tall hedge nursery. If the soil is clay or lacks fertility, soil improvement should be carried out and sufficient base fertilizer applied: 3000 kg of decomposed organic fertilizer per mu, plus 50 kg of phosphate fertilizer. To prevent underground pests, apply 2 kg of the insecticide carbofuran per mu.
Plowing and bed making
The first plowing uses deep plowing, with a depth of more than 25 cm, then harrow finely once. A second plowing then makes the bed surface level. Dig border ditches around the field, with a depth of 50-80 cm and a width of 60 cm. Dig a middle ditch in the center of the field, connected to the border ditches, 40-60 cm deep and 50-60 cm wide. Make the beds: bed surface width 110 cm, with the soil clods on the bed surface broken up finely, the center of the bed surface slightly higher and the two sides slightly lower. Between each seedbed, open a walkway, more than 25 cm deep and 40 cm wide, with the ditches connected and drainage flowing smoothly.
Field planting
The field planting time for the cutting orchard and tall hedge seedlings is from October to April of the following year. For field planting in the cutting orchard, the plant spacing is 35 cm and the row spacing is 40 cm, the seedbed width is 110 cm, with 3 plants planted across, 3000 plants per mu. Before transplanting, the above-ground part should be pruned, retaining a height of 15 cm; the cut branches are used as cuttings. When the cutting seedlings are transported to the field edge, direct sunlight must be avoided, they must not be piled up, and they must be planted in the field promptly. Dig holes at fixed points according to the plant and row spacing, with a moderate field planting depth, slightly deeper than the original root crown of the plant. Then cover the base of the seedling with fine soil and press it down gently.
Management
On the day after transplanting, water thoroughly to settle the roots. If there are consecutive sunny days, water on the 4th day after transplanting, and thereafter water about once every 10 days; if there is rain, drain promptly. Carry out full-light management to promote lignification. Apply sufficient base fertilizer before field planting. Starting 15 days after field planting, apply urea at 5 kg/mu about once every 10 days. Apply urea in April, compound fertilizer in May-June, apply less nitrogen fertilizer and more phosphorus and potassium fertilizer in July-August, apply urea at 0.2% concentration once every 10 days in September, and apply decomposed organic fertilizer from October to December, buried in shallow trenches between the plants. Combined with fertilization, loosen the soil and weed, so that there are basically no weeds on the seedbed. After rain, loosen the soil promptly on sunny days to prevent the soil surface from crusting.
Disease control
A common one is leaf blight, caused by Pestalotiopsis fungi, which harms leaves and branches. The disease spots are yellowish brown, and in severe cases cause the whole plant to die. Control methods: strengthen management and apply more decomposed organic fertilizer. Enhance tree vigor and improve disease resistance. Remove diseased branches and leaves and burn them in a centralized manner. In the early stage of the disease, spray 50% Shibaike 500 times solution, 75% chlorothalonil 500 times solution or 80% zineb 600 times solution, once a week, spraying 2-3 times in succession. Rejuvenation for vigor: mother plants that are repeatedly cut for cuttings tend to age, and the vigor of the cuttings weakens. To enhance the vigor of the cuttings, mother plants over 6 years old must be rejuvenated. In February of that year, cut the mother plant flat at a height of 15 cm above the ground, then promptly loosen the soil, fertilize and earth up to promote the sprouting of adventitious buds.
Cutting propagation
Collecting cuttings
In early September, cut semi-lignified branches of the current year, retaining the height of the mother plant. One-year-old mother plants retain 15 cm, two-year-old retain 20 cm, and three-to-five-year-old retain about 25 cm. The cuttings are 4 cm long and retain 2 leaves, while keeping the crown shape of the mother plant flat. The key to collecting cuttings is keeping the cuttings fresh; this should be done in the morning or evening, and the cut branches should be covered with moistened non-woven fabric and sprinkled with water to keep them fresh. During transport, cool them down and keep them moist. After arriving at the destination, place them indoors, spread them out as soon as possible, spray them with water, and carry out cutting promptly.
Plant rooting promoter for cuttings
Use 1 g of "Sensheng No. 1" plant rooting promoter, dissolve it in 30 ml of alcohol for 30 minutes, then add 600 ml of water, and dip quickly for 2 seconds before cutting.
Substrate formula: vermiculite : peat : perlite = 4 : 5 : 1, dry bulk density 0.20, total porosity 87.05%, macroporosity 26.05%, microporosity 61.00%, maximum water holding rate 4.15. pH value 6.87, EC value 0.85 mS/cm, total nitrogen 0.90%, total phosphorus 526.24 mg/kg, total potassium 5632.47 mg/kg, calcium 1845.25 mg/kg, magnesium 2456.25 mg/kg.
Cutting on cutting seedling beds
The ground seedbed is 100 cm wide, and the walkway is 40 cm wide and 25 cm deep. The elevated seedbed is 168 cm wide and 80 cm high. Lay ground cloth on the bed surface, then fill in the substrate to a thickness of 8 cm, disinfect with 600 times potassium permanganate solution, and cover with film for 24 hours. The cutting depth is 2 cm, inserted upright; after inserting, water thoroughly immediately, and after the water on the leaves evaporates, immediately spray 600 times carbendazim solution for disinfection and disease prevention. Then build a small arch shed, cover it with film, seal it all around, and keep the relative air humidity inside the shed above 95%.
Management
Before cutting, set up a shade net above the seedbed: cover 1 layer in May-June; cover 2 layers in July-August. When the daily maximum temperature is below 30°C, the shade net can be completely removed for full-light management. Hang a rod-shaped thermometer inside the small arch shed; when the air temperature inside the small arch shed is above 36°C, take misting measures to cool it down. Especially on sunny and hot days, from 10 a.m. to 4 p.m., mist once every half hour to bring the temperature down below 36°C. Check the substrate moisture frequently, and water when it looks dry. About once every 7 days, water once in the evening or early morning. After 30 days of cutting, when more than 90% of the cuttings have rooted, hardening off can begin. Choose the evening to remove the film: first ventilate from both ends for 2 days, then remove it completely. After removing the film, carry out full-light management. Water promptly and spray foliar fertilizer. From December to January of the following year, only water promptly to maintain substrate moisture. Starting in February, water once every 10 days while also spraying foliar fertilizer. Time to finished seedlings: cuttings taken in early September, leaves fall after rooting, not including the dormant period (leaf-fall period), cultivation time 4 months, seedling height above 8 cm, finished product rate 90%.

The peak flowering period is from May to July (early April to early July south of the Yangtze River), and the inflorescences continue successively until October.
Ecological habits of Weigela florida cv.Red Prince
Weigela florida cv.Red Prince likes light, is cold-tolerant, and fears waterlogging. It likes fertile, moist soil with good drainage.
Weigela florida cv.Red Prince has strong cold and drought adaptability and has been rated an excellent variety for welcoming the Green Olympics. In spring, water once or twice a month. In early spring, before the branches of Weigela florida cv.Red Prince sprout, the dry and withered branches should be cut off, and fertilizer should be applied appropriately to promote robust growth of new branches. In summer, when the temperature is high and there is more rainfall, attention should be paid to drainage to prevent root rot. In winter, no cold protection is needed, but before winter begins, water once with fertilizer water to improve its cold resistance. No further fertilization or watering is done during the winter.
Cultivation techniques for Weigela florida cv.Red Prince
Weigela florida cv.Red Prince likes light, is cold-resistant, drought-resistant, and relatively simple to manage. It is also fairly shade-tolerant and is suitable for growing in sandy soil and a warm, sunny environment. When transplanting seedlings in spring, they do not need a soil ball; when transplanting in summer and autumn, they need a soil ball. In early spring, before the branches sprout, dry and withered branches or old and weak branches should be cut off, and fertilizer applied appropriately to promote robust growth of new branches. In summer, during the period of vigorous growth, attention should be paid to pruning. During cultivation, it can be pruned into a spherical shape or grown into a single-trunk form. Before winter begins, water once with fertilizer water to improve its cold resistance and promote abundant flowering the following year.
Water and fertilizer management
Weigela florida cv.Red Prince likes a moist environment, and water management should be strengthened during cultivation. After planting, water the first three waterings well, and thereafter water once or twice thoroughly each month depending on rainfall and soil moisture, with the soil best kept at a little more than half moisture. In addition to watering well, foliar misting can also be used to replenish water; this can effectively increase the survival rate of the seedlings. In the second year, water to promote greening promptly in early spring; April to June is its flowering period, when watering can be appropriately controlled, watering thoroughly once a month is enough, as too much water during the flowering period tends to make the flowers wither prematurely; watering after flowering can follow that of the first year of planting.
Weigela florida cv.Red Prince likes fertilizer. When planting, some barnyard manure can be applied as base fertilizer. After flowering, a nitrogen, phosphorus, and potassium compound fertilizer should be applied as a top dressing. In late autumn, together with watering for freezing, apply some rotted and fermented cow or horse manure or sesame paste residue; after sprouting the following spring, some urea can be applied, and an appropriate amount of phosphorus and potassium fertilizer should be applied after flowering. After the Beginning of Autumn, stop fertilizing, and in early winter barnyard manure can be applied.
Pruning and shaping
Pruning of Weigela florida cv.Red Prince is generally carried out in early spring. Its plant shape is generally a shrub form, with 5 to 7 branches per plant. Because it flowers on one- and two-year-old branches, and older branches do not easily bear flowers, care should be taken during pruning to renew flowering branches promptly. To keep the plant ventilated and exposed to light, overly dense branches should also be thinned promptly. In addition, thin and weak branches, dry and withered branches, and diseased and pest-damaged branches should also be removed promptly. After flowering, if seeds are not needed, the spent flowers should also be removed promptly, so as to avoid consuming a large amount of nutrients through seed setting and affecting growth and flowering the following year.
Propagation methods
Weigela florida cv.Red Prince can be propagated by various methods such as seeding, cutting, division or layering.
Seed propagation
Seeding is usually carried out indoors in pots in mid-to-late April in spring, and is generally used for raising seedlings in large quantities. Weigela seeds are small and not easy to harvest, so they should be harvested promptly after the fruits mature in October, threshed, air-dried, and the cleaned seeds stored. In mid-to-late April of the following spring, soak the seeds in cold water for 2 to 3 hours, mix with 2 to 3 times the amount of sand, spread flat in a wind-sheltered, sunny place to sprout, and sow after 6 to 7 days. Before sowing, water the bottom thoroughly, scatter the seeds and sand together on the bed surface, cover with about 0.5 cm of soil, and cover after sowing to keep the soil moist until the seedlings emerge completely, then remove the cover.
Cutting propagation
Cuttings are divided into two types: hardwood cuttings and semi-lignified cuttings. For hardwood cuttings, one-year-old mature branches are commonly used, cut into 15 cm to 20 cm cuttings for open-field cutting. Semi-lignified cuttings are carried out in summer from June to July, cutting semi-lignified terminal branches as cuttings, and rooting powder can be used to promote rooting. Cutting can be carried out under a shade shed, in a greenhouse, or on a full-light mist cutting bed. The cutting bed is best disinfected with phoxim; besides eliminating pests, it also has a sterilizing and disease-preventing effect.
Layering or division propagation
Division should be carried out in early spring before sprouting. Layering propagation is best carried out during the growth period in early to mid-June. Press the lower branches of the plant into the soil, taking care to cut the bark of the branches buried in the soil with a knife so as to produce callus tissue and promote rapid rooting. Wait until before sprouting in early spring of the following year, then transplanting can be carried out.
Key points of propagation
Weigela florida cv.Red Prince is a horticultural variety of Weigela florida. The plant is 1 to 2 m tall, with pale red young branches and grayish brown old branches. It blooms in early summer, with dense flowers and a carmine-red corolla that is bright and pleasing to the eye. The flowering period lasts as long as one month, starting to bloom in early May and continuing to early to mid-June. It can be planted in courtyards, parks, and lawns, and can also be planted in clusters beside roads, on slopes and other places, looking very beautiful. It is widely cultivated in Northeast and North China. Weigela florida cv.Red Prince can be propagated by various methods such as cutting, seeding, division or layering.
Cutting propagation
Cuttings are divided into two types: hardwood cuttings and semi-lignified cuttings. For hardwood cuttings, one-year-old mature branches are commonly used, cut into 15 to 20 cm cuttings for open-field cutting. Semi-lignified cuttings are carried out in summer from June to July, cutting semi-lignified terminal branches as cuttings, which root very easily. To improve the cutting survival rate, dip quickly in 500 mg/L indolebutyric acid (or other rooting powder, used according to the instructions) to promote rooting. Cutting can be carried out under a shade shed, in a greenhouse, or on a full-light mist cutting bed. The cutting bed is best disinfected with phoxim; besides eliminating pests, it also has a sterilizing and disease-preventing effect.
Seed propagation
Seed propagation is generally used for raising seedlings in large quantities. Weigela seeds are small and not easy to harvest, so they should be harvested promptly after the fruits mature in October, dehydrated, air-dried, and the cleaned seeds stored. In mid-to-late April of the following spring, sow indoors in pots. After soaking the seeds in cold water for 2 to 3 hours, mix with 2 to 3 times the amount of plain sand, spread flat in a wind-sheltered, sunny place to sprout, and sow after 6 to 7 days. Before sowing, water the bottom thoroughly, scatter the seeds and sand together on the bed surface, cover with about 0.5 cm of soil after sowing, then add a cover to keep the seedbed moist until the seedlings emerge completely, then remove it.
Layering or division propagation
For layering or division propagation, division must be carried out in early spring before the plant sprouts. Layering is best carried out during the growth period in early to mid-June. Press the lower branches of the plant into the soil, taking care that the branches buried in the soil must have their bark cut with a knife so as to produce callus tissue and promote rapid rooting. Wait until before sprouting in early spring of the following year, cut off from the part of the layered branch that was not buried in the soil, and then transplanting can be carried out.
Symptoms of disease control in Weigela florida cv.Red Prince
It harms the branches of Weigela. The disease spots on the twigs are tea-brown with indistinct edges, bearing small black granules, namely the pycnidia of the pathogen. Severely affected branches die.
Control methods
1. Care carefully, apply more organic fertilizer, loosen and improve the soil, drain promptly after rain, prevent moisture retention, and prevent freeze damage.
2. During pruning, cut off diseased branches, and remove diseased branches or disease spots before conidia are produced, so as to reduce the source of infection.
3. During the period of conidia release, spray once every half month with jiemanling : asomate : water = 2:1:100, which can eliminate the overwintering bacteria of branch blight. In addition, you can also spray 40% carbendazim or 36% thiophanate-methyl 500 times solution, 50% benomyl wettable powder 800-**** times solution.

Propagation methods
The propagation methods of Weigela florida cv.Red Prince include: cutting, division, and layering.
Cutting: carried out from June to July, with cuttings about 10 cm long, the upper part cut flat and the lower part cut into a horseshoe shape, retaining two or three leaves. After dipping in ABT rooting agent, insert into a disinfected fine river sand seedbed, with plant and row spacing of 10 cm × 10 cm. After inserting, water thoroughly immediately, cover with a shed to keep moist, and set up a shade net. Generally, rooting occurs in about 25 days.
Division: division is generally carried out in late autumn or early spring. Select vigorous Weigela with more branches for division. Before division, water the plant thoroughly once, dig up the plant, split it open with a sharp knife, and the new plant should have more than 3 branches, then plant them separately.
Layering: in early June, cut and wound the lower part of a Weigela florida cv.Red Prince branch, then press it into the soil, keeping the soil moist regularly. The following spring it can be separated from the mother plant and planted separately.
