In January, the temperature is the lowest and the weather is the coldest of the year. The average monthly temperature ranges from -4.5°C (Beijing) to 4.2°C (Shanghai). In the north, potted ornamental plants that can be displayed in the courtyard must be particularly cold-resistant, including: white pine, spruce, Japanese spruce, Huashan pine, Japanese five-needle pine, black pine, brocade pine, Nandina domestica, holly, boxwood, large-leaf boxwood, yew, Torreya grandis, podocarpus, cypress, green cypress, true cypress, juniper, dragon cypress, Chinese juniper, pyracantha, wintersweet (in full bloom), ginkgo, plum blossom, Buddha's hand, European dwarf palm, palm tree, Chilean sea coconut, Washington palm, etc. In the southern region, there are also potted ornamental plants that can be displayed, such as: banyan, cycad, Canary Island date palm, long spike palm, silver sea coconut, palm bamboo, silver acacia, silver birch, ten major virtues, Japanese maple, money plant, silver-leaf money plant, golden apple coral, silver tooth palm, etc. In relatively warm regions like the Jiangnan area, some herbaceous flowers can also be displayed, such as: Aspidistra elatior, Yucca elephantipes, lucky grass, kale, daisy, pansy, marigold, etc. No matter whether it is a woody ornamental plant or a herbaceous ornamental plant, when displayed outdoors, it should ensure that the soil in the pot does not freeze and take good measures to prevent frost and keep warm.
Propagation of Courtyard Flowers
1. Sowing: If there is a double-layer plastic greenhouse with good moisture retention in the courtyard, you can plant Asparagus plumosus, Clivia, Begonia, Cyclamen, winter coral, Sinningia speciosa, African daisy, pansy, calendula, Nemesia, snapdragon, Calceolaria, Nemophila, etc. inside. However, it is necessary to ensure that the temperature inside the greenhouse can meet the minimum temperature requirements for the germination and seedling growth of different types of flower seeds. As long as the old land in the local area is not frozen in this month, the types of woody ornamental plants that can be sown outdoors in the courtyard include: peony, camellia, pagoda tree, Sapindus mukorossi, camphor tree, Ligustrum lucidum, Ligustrum japonicum, Elaeocarpus decipiens, wisteria, palm, Chinese parasol tree, pond cypress, pyracantha, Photinia serratifolia, Photinia davidsoniae, osmanthus, michelia, Chinese rose (Elizabeth), fortune fruit, holly, Chinese tallow tree, Koelreuteria paniculata, etc. Pay attention before sowing, in order to prevent underground pests from harming seeds, you can sprinkle a small amount of tea seed cake, tobacco ash, or农药furan dan, etc.
2. Cutting: In this month, in a simple plastic greenhouse or double-layer plastic greenhouse with good moisture retention, the ornamental plants that can be cut include: jasmine, aglaia, geranium, hanging clock, Belgian azalea, bougainvillea, umbrella grass, gem flower, jade leaf, finger citron, stone lotus, epiphyllum, Hydrangea macrophylla, cold water flower, shrimp robe flower, Chinese lantern flower, resurrection flower, dragon spitting bead, schefflera, rubber tree, Daphne odora, Chinese cinnamon, Guangdong evergreen, hydrangea, Cordyline fruticosa, hibiscus, Begonia masoniana, gray lily (African jasmine), banyan, silver-leaf money plant, etc. In this month, in the courtyard, or with a plastic film covered on the ground, the ornamental plants that can be cut include: plum blossom (such as pink, green calyx, etc.), red-leaf plum, Chinese rose (such as Elizabeth, profuse, climbing, etc.), wintersweet (with heel), spirea, boxwood, Magnolia grandiflora, Chinese hibiscus,石榴, silver spruce, Chinese juniper, June snow, osmanthus, hypericum, golden bell, forsythia, snowflake spray, jasminum, gardenia, Lagerstroemia indica, golden-leaf Ligustrum lucidum, red-leaf Berberis thunbergii, etc. The cutting substrate can be general sandy loam or a mixture of vermiculite and river sand.
3. Grafting: In the southern region, if the indoor temperature in the greenhouse can be maintained above 20°C, camellia or red camellia can be used as rootstock for single-bud stripping and skin grafting of small camellia, covered with plastic bags to keep moisture, and the survival rate is relatively high. The one-year-old seedlings of Acer pseudosieboldianum can be used as rootstock for grafting red maple and feather maple with inflatable bags. One-year-old apricot and Japanese apricot can be used as rootstock for cut grafting of excellent plum varieties. Elizabeth or wild rose can be used as rootstock for cut grafting of excellent rose varieties. In Guangzhou area, during the period from Slight Cold to Great Cold, you can use Citrus limon as rootstock for cut grafting of seasonal orange and kumquat, and the survival rate is relatively high.
4. Layering: In this month, the ornamental plants that can be propagated by low-pressure layering include: magnolia, camellia, wintersweet, plum blossom, weigela, gardenia, flowering crabapple, flowering almond, Thuja orientalis, cypress, snowball, sweet osmanthus, Chinese osmanthus, Daphne odora, four seasons osmanthus, August osmanthus, French holly, Chinese gray lily, etc.
