Arrangement of Courtyard Flowers
Types of flowering plants suitable for courtyard display enter the spring and summer JIAOTI of May, the temperature in all parts of the country rises sharply, and the sunshine becomes increasingly strong, and the types of potted ornamental plants that can be displayed in the courtyard increase, such as roses, Araucaria heterophylla, Weeping cherry, Canary Island date palm, rubber tree, Japanese black pine, podocarpus, nandina domestica, amaryllis, jasmine, raphis, cycas, king coconut, areca palm, variegated ficus benjamina, palm, bottle palm, cinnamon, beautiful needle palm, European primrose, lily (dwarf potted), pomegranate, peony, michelia figo, maple, milan, four-season osmanthus, shaddock, etc.
Propagation of Courtyard Flowers
1. Sowing The types of grass flowers suitable for sowing in May include: four-season primrose, begonia, cockscomb, etc. The types of woody flowers include: loquat, star anise, broadleaf ten功劳, areca palm, bottle palm, osmanthus, among which the seeds of the first five types of flowers can be sown immediately after collection, only the seeds of osmanthus, which mature black, soften, and are covered with white powder, need to be washed and stored in clean wet sand until February of the following year, and then sown when the seed coat cracks and the white embryo is exposed. When sowing seeds collected immediately, the following points should be noted: One is to keep the seedbed moist, but not waterlogged; the second is to cover with grass to prevent the seeds from "recalling"; the third is to remove the grass covering in 2 to 3 times after the seeds germinate, and set up a shed in time to shade to prevent the sun from scorching the young. In addition, although loquat seeds are large, their seedling tip ability is weak and prone to bending. Deep sowing will affect the seedling rate and seedling rate, so it is advisable to sow shallowly. Generally, the furrow depth is 2 to 3 cm and the soil is covered to the full.
At this time, the cultivated Gladiolus bulbs can bloom in August; the cultivated Polianthes can bloom between August and September.

Management of Courtyard Potted Flowers
1. Transplanting At the beginning of May, after the white magnolia and Erqiao magnolia flowers have faded, and just before the leaves have not yet unfolded, the transplanting can be carried out with a higher survival rate. Some late-budding flower trees can also be transplanted in May, such as crape myrtle, redbud, hibiscus, pomegranate, and Albizia julibrissin.

2. Shaping
① Pinching, for ground-planted grass flowers, such as tatarian aster, begonia, coreopsis, dianthus, dahlia, coleus, etc., pinching should be carried out in mid-to-late May to promote branching. For woody flowers, such as plum blossom, wintersweet, and gardenia, pinching can also be used to promote lateral branching of the plant.
② Pruning, for the flower trees planted in the courtyard, such as redbud, crape myrtle, pyracantha, hydrangea, pomegranate, etc., dead branches, diseased and insect-infested branches, and weak branches can be pruned to adjust the plant shape.
3. Fertilizing For the types of ground-planted flowers that continuously form flower buds and can continue to bloom, such as rose pomegranate (a type of pomegranate), rose, hypericum, etc., and the types of flowers that bloom in summer, such as gardenia, hibiscus, crape myrtle, hydrangea, snowball, datura stramonium, and summer azalea, and the types of flowers that start to differentiate flower buds around June, such as Camellia japonica, plum blossom, peony, and osmanthus, starting from May, a balanced quick-acting fertilizer of nitrogen, phosphorus, and potassium can be applied every half month.
4. Pest and Disease Control Special attention should be paid to the prevention and control of red spider mites, scale insects, wax scale insects, and aphids in May. For the larvae of the silk moth found on the green hedge of Buxus in the ground, timely spraying of pesticides for prevention and control should be carried out.
5. Seed Collection Ground-planted grass flowers such as cornflower, kale, daisy, marigold, poppy, dianthus, etc., can harvest seeds in May.
Management of Courtyard Potted Flowers
1. Potting Some potted flowers in the northern region can be repotted when they come out of the room or greenhouse. Types include: Camellia, azalea, rubber tree, schefflera, Araucaria heterophylla, Strelitzia reginae, orchid, dragon's blood tree, areca palm, fishtail palm, etc.
2. Shaping In the northern region, the white magnolia, milan, michelia figo, michelia champaca, and Camellia can be pruned to remove dead branches, weak branches, etc., to maintain a good plant shape; the overgrown branches of potted plum blossom, wintersweet, pyracantha, and crabapple can be topped to promote the healthy development of the plant; the flowering roses, Weeping cherry, peony, and thorny elaeagnus can be pruned and pruned.
3. Watering The temperature in May rises, and for the potted flowers placed in the courtyard, the amount of watering should be increased, and it can be controlled once a day. Pay attention to spray water around the plants on sunny days to increase air humidity; if it rains continuously, check the pot soil frequently, and if there is waterlogging in the pot, remove it in time and repot as soon as possible. In the northern region, when watering potted flowers that prefer acidic soil conditions such as gardenia, Camellia, azalea, white magnolia, michelia figo, bead tree, Daphne odora, cycas, raphis, monstera deliciosa, etc., a small amount of ferrous sulfate can be added to the water to prevent physiological chlorosis of the plants. For plants entering dormancy such as cyclamen and calla lily, stop watering and place them in a moist and cool location.
4. Fertilizing May is the vigorous growing season for potted flowers. For those types of flowering, fruiting, and fragrant plants, such as white magnolia, milan, rose, shaddock, gardenia, bead tree, jasmine, Camellia, plum blossom, wintersweet, peony, etc., a balanced compound fertilizer of nitrogen, phosphorus, and potassium can be applied every half month, or a small amount of potassium dihydrogen phosphate can be added to the water used for watering and fertilizing, which is beneficial to the plant's restorative growth, flower bud differentiation, or continuous bud formation and flowering. For those types of plants that are mainly for leaf viewing, such as monstera deliciosa, asparagus plumosus, angel wings, rubber tree, red (green) jade, cycas, giant green, green emperor, one-leaf orchid, Guangdong evergreen, etc., a well-rotted cake fertilizer water can be applied every half month; for variegated leaf plants such as Variegated snake plant, variegated bromeliad, golden heart Dracaena fragrans, variegated dracaena fragrans, variegated leaf, Ficus benjamina, coleus, white butterfly syngonium, ginger, elephant ear, money tree, fittonia, syngonium podophyllum, green philodendron, golden pothos, string of pearls, etc., 0.2% potassium dihydrogen phosphate can be applied to the leaves in addition to applying a thin cake fertilizer liquid, making the leaves appear more bright and bright.
5. Shading In May, it is advisable to move potted plants that prefer semi-shade or shade to a shade shed or under the tree shade, such as monstera deliciosa, raphis, calathea, asparagus plumosus, giant green, red (green) jade, green emperor, variegated leaf, syngonium podophyllum, orchid, azalea, Camellia, camellia sasanqua, Strelitzia reginae, bead tree, clivia miniata, begonia tuberhybrida, begonia maculata, nandina domestica, dracaena fragrans, pothos, golden pothos, ivy gourd, boston fern, etc. For those plants that prefer light, sufficient sunlight must be provided, such as cycas, pomegranate, rose, jasmine, wintersweet, pyracantha, broadleaf ten功劳, etc.
6. Pest and Disease Control For potted roses, floribunda roses, and miniature roses cultivated in the courtyard, attention should be paid to the prevention and control of powdery mildew and brown spot disease. If leaf-eating pests are found, they should be promptly controlled with 90% trichlorfon crystals diluted 1000 times. For the citrus swallowtail butterfly larvae found on the plants of the Rutaceae family such as shaddock, kumquat, fingered citron, lemon, etc., they should also be promptly captured and killed or controlled with fenvalerate.
