September Courtyard Flower Management
Today, the editor will introduce some knowledge about home flower cultivation, focusing on courtyard flower management in September. Next, the editor of this site will introduce relevant content to everyone.
1. Transplanting Since the temperature in September is still relatively high, there is no need for special circumstances to transplant flowers and trees in the courtyard. However, if it is for the arrangement of a new courtyard or the renovation of an old one, and with the premise of having good soil balls, transplantation can also be carried out. Types include: oleander, dragon pine, mock orange, Suiji cypress, osmanthus, camellia, red-leafed barberry, golden-leafed ligustrum, boxwood, kowhai, French holly, red flower hawthorn, variegated peach-leafed coral, etc. Transplanting should involve intensive pruning and strengthening watering, spraying, and shading management to ensure successful transplantation. Some herbaceous flowers can still be planted or potted for appreciation in October. Types include: scarlet sage, Chinese rose, marigold, parrot feather, Chinese pink, celosia, Catharanthus, sulfur cineraria, small wax begonia, marigold, dwarf banana, early chrysanthemum, etc.
2. Pruning Continue to prune courtyard hedges and ball-shaped ornamental plants that are growing vigorously and have strong germination abilities. This is also the last pruning for ball-shaped plants in the growing season in the northern region. Suitable for pruning are: boxwood, French holly, Photinia serratifolia, ligustrum, dwarf ligustrum, red-leafed barberry, golden-leafed ligustrum, golden-edged cypress, etc. Ball-shaped ornamental plants suitable for pruning include: dragon pine, Suiji cypress, boxwood, Japanese apricot, hawthorn, holly, Photinia serratifolia, Pittosporum, pyracantha, golden bell, etc. For ground-planted herbaceous flowers, such as scarlet sage, Chinese rose, sulfur cineraria, Kochia scoparia, marigold, and parrot feather, the top can be pinched off. It is recommended to pinch off every 10 days to promote a full plant shape and more inflorescences on the lateral branches, stopping after the end of September. For woody flowers that bloom continuously for a long time, such as varieties of roses, flowering cherry, micro roses, climbing roses, crape myrtle, flowering pomegranate, Lantana camara, Bougainvillea glabra, etc., remove the withered flowers and stems and moderately prune the flowering branches to effectively promote reblooming.
3. Watering In September, the climate is relatively dry. Continuing to water and spray newly transplanted trees and flowering shrubs in the courtyard is a key measure to consolidate their survival. This includes watering the roots to keep the soil moist but not waterlogged; spraying water on the straw rope wrapped around the trunk to create a locally moist protective layer; and spraying the canopy to reduce leaf transpiration and increase humidity in the local space. In addition, for newly planted herbaceous flowers, proper spraying and moisture retention is also necessary.
4. Fertilization For ground-planted colorful foliage plants, such as golden-leafed ligustrum, red-leafed barberry, red maple, red flower hawthorn, variegated ginger, Croton, variegated peach-leafed coral, red mulberry, red-leafed dwarf cherry, red-leafed plum, red-leafed peach, etc., to maintain their bright leaf color, it is appropriate to apply phosphorus and potassium fertilizers. For continuously flowering or autumn ornamental fruit trees, such as crape myrtle, rose, osmanthus, kumquat, flowering pomegranate, Bougainvillea glabra, hibiscus, chrysanthemum,美人蕉 (banana flower), large wax begonia, Lantana camara, Nandina domestica, pyracantha, cinnamomum, kumquat, etc., as well as a large number of autumn ground-planted herbaceous flowers, it is recommended to apply a balanced fast-acting fertilizer with nitrogen, phosphorus, and potassium. For flowering plants such as kumquat, silver osmanthus, and dan osmanthus, fertilization should be stopped during the flowering period.
5. Disease and Pest Control For green caterpillars that harm flowers such as crape myrtle, pyracantha, and begonia, a 90% crystal of trichlorfon can be sprayed at 800 times dilution for control. For the starry longicorn that harms crape myrtle, loquat, and begonia, a poison stick can be inserted into the虫孔 (bug hole) for control. For powdery mildew that appears on rose and chrysanthemum plants, a 50% wettable powder of carbendazim can be used at 1000 times dilution for control in the early stage of the disease.
6. Seed Collection Seed collection of woody ornamental plants is mainly from the Magnoliaceae family, such as: Hepatica nobilis, Michelia, purple magnolia, white magnolia, Yunnan white magnolia, Lechang Michelia, multiflowered Michelia, deep mountain Michelia, broad-leafed magnolia, etc. In addition, there are: horse chestnut, crape myrtle, syringa, begonia, red bud, white杜鹃 (white azalea),红豆杉 (kokoro pine), bright-leafed蜡梅 (wax plum), etc. Seeds of the Magnoliaceae family, as well as those of kokoro pine, horse chestnut, begonia, and others, must be stored in moist sand until early spring of the following year after processing, and then sown when the seeds crack open. Herbaceous flower seeds that can be harvested include: marigold, zinnia, cosmos, four o'clock, celosia, Catharanthus, wheat straw chrysanthemum, daisy, etc., which should be shelled and dried immediately after harvest and stored until spring of the following year for sowing.
