Sowing</p><p>Woody flower species that can be sown include: tree peony, red-flowered camellia, Michelia species, magnolia species, manglietia species, horse chestnut species, summer sweetshrub, Canary Island date palm, etc. Among them, horse chestnut seeds can be sown in furrows, with the hilum facing downward when sowing; the covering soil should not be too deep, preferably 2 to 2.5 cm, and plastic film or rice straw should be added to retain moisture. Summer sweetshrub seeds can be soaked in cold water for 24 to 36 hours before sowing in the ground, and seedlings will emerge about 2 weeks after sowing. Except for summer sweetshrub, which can be dry-stored until the following spring for sowing, all the other species must be stored in moist sand. September is a great time for autumn sowing of herbaceous flowers. Herbaceous flower species that can be sown include: hollyhock, dianthus, tall catchfly, dwarf catchfly, pansy, snapdragon, petunia, California poppy, daisy, corn poppy, pot marigold, black-eyed Susan, iris, verbena, etc. In addition, greenhouse flowers such as cyclamen, primrose, nasturtium, cineraria, wax begonia, gerbera, and calceolaria can also be sown at this time, but they must overwinter in a plastic tunnel.</p><p>2. Cuttage</p><p>Using a half-sand, half-rice-husk-ash mixture as the cutting medium, woody flower species that can be propagated by moisture-retaining cuttage in the courtyard include: firethorn, leatherleaf mahonia, Michelia, bougainvillea, Weigela, spotted laurel, fuchsia, Viburnum macrocephalum, snowball viburnum, weigela, Brunfelsia, jasmine, pearl orchid, golden-veined shrimp plant, coral flower, rubber tree, schefflera, ti plant, etc. Using ordinary sandy soil as the seedbed, woody flowers that can be propagated by cuttage include: boxwood species, purple magnolia, hypericum, spiraea, pomegranate, rose of Sharon, crape myrtle, bridal wreath spiraea, hydrangea, French holly, golden-edged privet, red-leaf barberry, heavenly bamboo, fig, oleander, serissa, gardenia, Japanese fatsia, chaenomeles, tree peony, etc. Some herbaceous flowers can also be propagated by cuttage, such as scarlet sage, globe amaranth, marigold, sulfur cosmos, and cold chrysanthemum, etc.</p><p>3. Grafting</p><p>The following flower and tree grafting propagation can be carried out: using peony root sections as rootstock to graft superior varieties of tree peony; using peach, apricot and other seedling plants as rootstock to bud-graft and propagate flowering almond, ornamental peach, longevity peach, red-leaf peach, plum blossom, etc.; using green maple seedlings as rootstock to bag-moisture-retain and cleft-graft red maple, feather maple, etc.; using white magnolia seedlings as rootstock to bud-graft superior varieties of white magnolia and Yulan magnolia; using potted purple magnolia as rootstock to approach-graft white orchid; using citrus seedlings as rootstock to bud-graft kumquat, etc.; using fringe tree as rootstock to approach-graft osmanthus; using potted seedling wintersweet as rootstock to approach-graft superior varieties of wintersweet.</p><p>4. Layering</p><p>Ornamental flower and tree species that can be propagated by layering include: chaenomeles, weigela, hydrangea, gardenia, oleander, winter jasmine, Forsythia, osmanthus, purple magnolia, jasmine, Michelia, camellia, pearl orchid, French holly, snowball viburnum, Viburnum macrocephalum, bridal wreath spiraea, spiraea, etc.</p><p>5.
