March is the best time for planting in the south, while northern regions can start mid-April. Winter corals can be sown from March to April, with seeds not covered by soil, transplanted when 3–4 leaves appear, and planted or topped in June. Plant spacing should be 25–30 cm, with fruit ripening from November to February.
Cockscomb and Scutellaria barbata can be sown in March without covering soil, while iris, impatiens, periwinkle, snapdragon, marigold, and stalk chrysanthemum can be sown in March with soil cover. Cleome is planted from March to April, with seedlings 5 cm tall, spaced 30 cm apart, and topped in May, blooming from June to September.
Primrose varieties like dreams, peaks, top wines, dream purple, and orange can be sown from March to April, flowering from July to October. Zinnia, with varieties like butterflies, universe, dreams, stars, and rich, is sown from March to April, with 4–5 leaves planted or in pots, spaced 30 cm apart, topped 1–2 times to promote branching, and flowering from June to October.
Mimosa is sown in March, using plain sand, soaked in water, placed in warmth, avoiding direct sunlight. Seedlings emerge in a week, then transplanted into pots with a mix of garden soil and humus (8:2), fertilized every 4–10 days, and watered in the morning and evening if leaves droop. It blooms from July to September.
Soybean chrysanthemum is planted from March to April, and can also be grown in autumn. It takes about 10 days to grow, and can be cut with tender branches. Spacing is 40 cm, with controlled fertilizer and water. Flowering occurs from June to August.
Aster varieties like Matsumoto, ladies, serenade, meteors, carpets, treasures, fire, and Minnie are planted from March to April, with flowering 70 days after planting. Autumn cold beds help winter them, with flowering from May to June. Seedlings 10 cm tall are planted or potted, with spacing 20–25 cm, and pruning to promote branching.
Qianqianhong has small dwarfs, square arrays, same body, aphorisms, Buddha light, and other varieties. Sown from March to April, mixed with fine soil (with cotton wool outside the seed) and soaked, germination at 16–20°C. Planted 40–50 days after emergence, spaced 30 cm apart, and fertilized every half month. Resistant to pruning and dry conditions, flowering from July to August.
Pine leaf chrysanthemum prefers warm, dry, and ventilated conditions, not cold-resistant, mainly propagated through cuttings in spring and autumn. Rooting at 20–25°C for three weeks, with moisture control. Flowers from June to September.
Two-year-old flowers sown last autumn begin flowering in March. Cold-tolerant species like pansy, calendula, and daisy are already in full bloom. Select the best plants and prepare for seed collection.
Perennial flowers go dormant in winter, and spring is the best time for ramets and repotting before new growth. Ramets and pot changes should be done after the night cream ends and before germination. Guolan can be rametted from March to May, with shrubs aged 2–5 years divided into clumps with 1–3 roots. Plants from February and March can bloom in May.
Rhizome plants like German iris and yellow iris sprout in early March, flowering from April to May. They are usually rametted every three years, with 1–2 buds per plant before new roots develop. Chrysanthemums grow at 10°C, with southern China able to propagate in March, but not directly used for production. Lavender, Madrid, and beautiful sky varieties are cut in spring and autumn, flowering from July to August.
Evergreen perennials like geranium, nasturtium, four seasons sea bream, and New Guinea phoenix are pruned, fertilized, and propagated through cuttings after wintering.
For bulbous plants, freesia flowers in March in central China, with cut flowers harvested after the first bloom. Gladiolus bulbs stored from fall break dormancy in winter and germinate when temperatures are suitable. Large-flowered varieties bloom around 100 days after the next species, with flowering dates determined accordingly. Clivia and ranunculus also bloom in March, with best strains selected for seed retention. Zhu Dinghong begins growing in March, often potted with one ball per pot. Purple leaf sorrel can be propagated in March.
Foliage plants should not be moved outdoors in March, kept cool and warm. Some cold-tolerant species like spider eggs, evergreen, auspicious grass, and Shichangpu can be exposed in the south, with repotting or ramets done every 3–5 years.
Cactus and sizing plants remain cold in March, so avoid moving them outdoors or watering/fertilizing. If grown in the south, they can be placed in areas with good outdoor lighting.
Deciduous woody flowers and trees should be transplanted before spring germination, such as hibiscus, pomegranate, bauhinia, crape myrtle, and plum. March is the end of the best transplanting period, so act early. Woody flowers like Milan, jasmine, and white orchids should not be transplanted, repotted, or moved outdoors in March due to fluctuating temperatures.
Rhododendrons bloom most from March to April, and can be fertilized immediately after flowering to encourage new shoots. Roses, bergamot, peaches, apricots, cherries, bauhinia, crape myrtle, hydrangeas, sweet-scented osmanthus, and viburnum should receive germination fertilizer, primarily nitrogen-phosphorus, using decomposed cake fertilizer water or animal manure with phosphoric acid. Apply every 7–10 days for 2–3 times. Peonies, purple magnolia, and various fruit trees can be planted in front of flowers.
Prevent and treat black spot, powdery mildew, anthracnose, and gray mold. Deciduous flowers can be sprayed with a 0.3-degree stone sulfur mixture once. After germination, spray 800 times 70% methyl thiophanate or 75% chlorothalonil.
Honeysuckle, peach blossom, chrysanthemum, and rose are vulnerable to aphids, so spray 1000 times imidacloprid before and after germination.
Solenoid valves are electromechanical devices that are used to control the flow of fluids or gases in a variety of applications. They are classified based on their function, construction, and application.
