Garden arrangement
(1) Flower types suitable for garden display In the area south of the Yangtze River Valley, a considerable part of potted ornamental plants after the Ching Ming Festival can be displayed on the courtyard, such as Araucaria, Camellia, Five-needle Pine, Tetradia, Apostolica, Cycad, King coconut, palm, hollyhock, hollyhock, canarian date, phoenix, strelitzia, rubber tree, monstera, spring plume, smiling, southern bamboo, jasmine, yew, red Maple, Bitao, Shou Tao, Octagonal Gold Plate, Cymbidium, Palm Tree, Peach Leaf Coral. The courtyard in the north region can display black pine, white pine, Jinsong, cypress, spruce, yew, jimei, Meimei, broad-leaved Dagong, Huashan pine, Budi coconut, palm, European dwarf brown, Chilean wine Coconut and so on.
(II) Propagation of garden flowers 1. Seed garden flowers suitable for sowing in April are: cultivars, cockscombs, impatiens, a bunch of red, amaranth, marzipan, chamomile, aster, Longevity flowers, Petunia, Antirrhinum, Camellia, Kochia. The garden woody flowers suitable for sowing in April are: magnolias, smiling species, magnolias, red maples, aesculins, and camellia that pass through the sand; other species include wisteria, waxberry, and summer wax Nan Tianzhu, rich seeds and so on. The seeds of the sand should be sown when the seeds are cracked. Seeds with hard shells, such as waxy plum, wisteria, acacia, bauhinia, and horse rake, can be soaked in cool water for 24 to 36 hours before sowing. The seed of the octagonal gold plate, when it matures at the end of April, can be used with the broadcast. Mushroom can be sown in plastic sheds in April. Bulbous tuberose, Gladiolus, dahlia, etc., can be planted at this time.
2. Cuttings from the south to the north, the buds that have not yet germinated are most likely to be used for cuttings, such as broad-leaved Mahonia, Mahonia, Octagonal Gold, Cyclovirobufo, Nandina, Begonia, Plum (Plastic flour) And other varieties such as green wolfberry, Podocarpus, pomegranate, crape myrtle, pyracantha, Spiraea, rose and other varieties. Daisy can also be cut at this time.
3. Grafting The types of flowers that can be grafted and propagated in April are: Peach-leafed coral and gold marbles. Grafting on the female plants such as Ginkgo biloba and grafting shoots of male plants can promote the results and avoid the trouble of annual pollination. The silkworms, seaweeds, seaweeds, waxy plums, dragon's claws, red burrs, green peaches, sweet-scented osmanthus, red maples, smiling flowers, white orchids, and peaches can also be grafted in April. In addition, in the southern region, crabgrass, Jinhu, peony, etc. can also be grafted at this time.
4. The types of garden flowers that the ramets can reproduce in April are: Mahonia, Broadleaf Mahonia, Nandina, Pteris, Begonia, Spring, Pomegranate, Fig, Magnolia, Musa, Canna, Dahlia, iris, Chunlan, green onion, lotus, water lily and so on.
5. Layers The garden flowers that can be plucked in April include plum blossom, wax plum, red maple, gardenia, mimosa, camellia, Podocarpus, sweet-scented osmanthus and sticky sea bream.
(III) Management of garden flowers and trees 1. Management of courtyard gardens and trees (1) Transplanting This month is the best time to plant trees and flowers in gardens, whether they are deciduous or evergreen, as long as their leaves do not spread out. Or the shoots are not long, they can be transplanted with earth balls, such as broad magnolia, camphor, smiling, ginkgo, white magnolia, horse chestnut, heather, persimmon, wax plum, plum, red leaf plum, red maple, etc. The diameter of a typical soil ball is about 6 to 7 times the diameter of the trunk, and depending on the damage of the root system, some branches and leaves are cut off as appropriate to reduce the transpiration of the leaves. For transplanting plants that have sprouted shoots, the soil ball diameter should be increased, and the strength should be reduced to the branches and leaves. Plum blossoms must not be transplanted after being displayed, otherwise it may easily lead to poor growth or death. Peony, peony bogey spring transplant. Planted grass flowers such as calendula, beautiful sakura, impatiens, a bunch of red, zinnia (4 to 5 true leaves), petunia, Chinese poppies, snapdragon, iris, green onion, mosaic wheat Winter, jade, grass, Ophiopogon japonicus, auspicious grass, etc., can also be transplanted at this time.
(2) After pruning flowers, the plums, plum blossoms, golden bells, peach blossoms, and spring cultivars shall be shrunk from the base of the flowering branches, and the appearance of the tree shall be adjusted; the redbuds, the escarpment, the peduncle Tangshan, papaya, Hubei jellyfish, smiling, summer wax, plum and other places to plant flowering shrubs, should be plastic trim, cut leggy branches, disorderly branches, internal litchi, thin branches, pests and branches, etc. It helps to form a good flowering plant shape.
(3) Fertilization No matter whether it is evergreen or deciduous shrubs, as long as it has not yet sprouted and shoots, it is possible to excavate the annular groove at the periphery of the root system and bury the applied organic fertilizer (cake fertilizer) or compound fertilizer. Fertilizer 0.5 to 1 kg.
(4) Prevent pests Cut off branches and leaves of plants that have been infected with pests, remove litter on the ground, and destroy them collectively. Rosaceae flowers and trees that are susceptible to diseases such as Chinese rose, Begonia esculenta, C. esculenta, Xifeng Begonia, papaya, pear trees, etc., are sprayed with Bordeaux mixture in time to prevent rust and brown spot.
2. Management of potted flowers in gardens (1) Changing pots Plants that have not yet been replaced in March but have sprouted leaves but have not yet displayed leaves may be changed in April. Do not excessively remove contaminated soil when changing pots. Pruning the root system, such as ginkgo, Araucaria, Jinsong, Podocarpus, black pine, Jinsong, red pine, pine needles, Osaka pine, harrog, pomegranate, crape myrtle, etc.; Change basin.
(2) The fortune tree seedlings in the southern region can be dug up at this time, and they can be air-dried for 1 to 2 days to allow them to lose part of the water, and then braided with odd-numbered stems of 3, 5, and 7 to make braids. After a good pressure with a heavy object, so that its shape is fixed, and then select the appropriate pots for planting.
The white orchids must not be shornly cut, and their branches have a relatively large medullary heart. After pruning, there will be a section of dead branches under their clippings. For this reason, the cut should leave at least 5 cm of the remaining strong buds.
Triangular maple bonsai can not be trimmed at this time, otherwise it will produce a lot of wound fluids, resulting in branches cut off, affecting the normal growth of the shoots.
The ornamental plants suitable for modeling in April are: Podocarpus, June snow, cypress, true cypress, eucalyptus, ginkgo, Pinus sylvestris, black pine, galanthus, escarpia, velvet cypress, cockroach, queque plum , Dieffenbachia, eucalyptus, paraffin wax, red hibiscus, weevil, plum blossom, etc. For pine bonsai, it should also be timely erased its male and female balls, in order to reduce the consumption of nutrients.
(3) Watering In April, the potted plants and flowers that are used to leave the house should be increased in watering volume, and the plants should be led as soon as possible. For bonsai, such as pine needles, black pine, Jinsong, and red pine, it is required to control watering, more sunlight, not to make the needles grow too long, so it is better to not dry or watering. In the south, the cycads should also be “snapped†to prevent the newly drawn leaves from affecting their viewing. For the newly opened flowers of Camellia, Rhododendron, Poinsettia (shrinking plants after the change basin), as well as flowers, lotus flowers, plum, Prynne, Jasmine, Zhulan, kumquat, etc., should pay special attention to control the amount of water, do not Make water in the basin cause rot.
(4) For fern, Chinese camellia, plum blossom, wax plum, rhododendron, chrysanthemum, Cymbidium, and jujube, etc. After flowering, the roots just begin to draw tender roots, and the fertilization concentration should not be too large. If cake water is used, The appropriate concentration of about 10%, with urea and potassium dihydrogen phosphate 0.2% to 0.3% as well, if the concentration is too large, will damage the young fibrous roots. It is also possible to embed a small amount of solid organic fertilizer or multi-component quick-acting compound fertilizer in different parts of potted plants.
(5) In case of insect-resistant potted orchids, check whether there are parasitic beetles on the leaves of the plants when they leave the house, and spray the plants with Bordeaux mixture or mancozeb, etc. to prevent the occurrence of leaf diseases. For tree bonsai in conifers, alfalfa, wood, querque plum, plum blossom, triangle maple, etc., the branches and leaves of the trunk exposed with xylem can be smeared with lime sulfur and other antiseptics. For potted plants infected with whitefly and scale insects, such as alfalfa, kumquat, lemon, gardenia, and camellia, they should be sprayed with dimethoate and other pesticides immediately after they leave the house.
(a) Potted flowers suitable for indoor display are still in flowering in April, and the types of flowers suitable for indoor display are: Camellia, Purse, Phlox, European Primula, Hualingcao, Peach, Peony (Flower), Gold Lotus, Pansy, Carter (Spring), Dendrobium (Spring), Strelitzia, Beauty Sakura, Freesia, Daffodil, Calla Lilies, Tulips, Rose, Cymbidium, etc. The foliage plants include: Amaranth, Araucaria, Cycad, Coin Tree, Cinnamon, Rubber Tree, Saxifraga, Transformed Wood, Acerola, Golden Brazil, Liquor, Green, Monstera, Little angels, palms, bamboo, tiger-eared orchids, purple-backed evergreen, pineapple, peach leaf coral, octagonal gold plate and so on.
(b) The propagation of flower on the balcony The flower propagation on the balcony is generally carried out in flower pots, and the quantity is relatively small. Due to special reasons such as large winds and low humidity, the management will be a little more troublesome. However, as long as you are careful, you can still make some small breedings for your own potted plants or give them a gift.
1. Seeding If a small amount of seedlings of Cinnamomum camphora and Clivia seeds are harvested, it is possible to pot the seedlings. For colder areas in the north, they should be put in the room first. Only when the outdoor temperature reaches 10°C to 15°C can they be moved to the balcony. In addition, a small amount of red, marigold, amaranth, primrose, winter coral, petunia, cockscomb, impatiens, etc., can also be planted on the balcony to embellish the balcony and interior during flowering. To keep your surroundings blooming, all seasons are like spring.
2. Cut the cuttings on the balcony, generally only in the large flower pots to reproduce a few species of flowers. The cutting matrix can be cleaned with sandy soil, fine sand, vermiculite or perlite. My personal experience is to use a mixture of enamel and fine sand in a ratio of 1:1 to make balcony pots. The types of ornamental plants suitable for cutting on the terrace in April include: bergamot (southern), hibiscus, geranium, rose pomegranate, poinsettia, rubber tree, jasmine, hollandia, red-backed osmanthus, bamboo, hydrangea, podocarpus, gamma Luomu, miniature rose, pyracantha, true cypress, cypress, peach leaf coral, smile, octagonal gold plate and so on. Evergreens should try to cut as many leaves as possible. After the cutting is completed, use a plastic film to cover the moisture. The northern region can be placed in front of the indoor sunny window to avoid freezing.
3. It is more difficult to graft and propagate on the grafted balcony than in the courtyard. It must be planted into the pot in the previous year and it is required to grow robustly before it can be grafted to survive. The types of flowers and trees that can be grafted on the terrace in April are: 1 tree with red maple, 5 needles pine (northern), Chinese rose, gold marbles, samaritan leaf coral, waxy plum (buds and grains), peach, and peach; 2 by the access to waxy plum, osmanthus and so on. Branches should be moisturized in order to improve their grafting survival rate. Chlamydoma japonica, Chrysanthemum bracteatum, Peony peony, etc. can also be grafted on the balcony or indoors at this time.
4. Ramets This is the most common method for flowering on the balcony. From April to April, when the outdoor temperature reaches 10°C to 15°C, the types of flowers that can be propagated on the balcony by branch are: Strelitzia reginae, Chrysanthemum, Iris, Monstera, Clivia, Prunus blumei, Cycad, Orchids, maize, paste stems jellyfish, pineapple, tiger-tailed orchid, palm, Zhulan, bamboo, agave, kidney fern, umbrella grass, cranes and so on. It is noteworthy that the axillary buds detached from the mother plant include cycads, pineapples, and clivia, and the plants with root systems can be directly planted on the pots. The root system-free ones should be planted first in the moist sand to sow the roots and wait for germination. Only after a good root system can you use the cultivated soil for planting, otherwise it will easily cause decay of the seedlings, resulting in failure of the ramets. In addition, if the root system is not very ideal, if the root system is not very ideal, in addition to painting the ash, charcoal shavings, and sulfur powder on the incision, it should be properly cut off to remove some of the foliage, so as to maintain the balance of water absorption and transpiration of the leaves. Only by ensuring that the ramets reproduce successfully. After the ramets, the clivia, pineapple, etc., can also be put in a plastic bag after being planted, opened every 1 to 2 days to give ventilation, in order to increase the humidity of the local space, which is very important for balcony flowers and trees. For the leafless rootless axillary buds peeled off from the parent cycads, creating a dark environment conducive to rooting and leaf extraction.
5. Layers The types of ornamental plants that can be propagated in high pressure on the balcony in April are: Podocarpus, rubber tree, red maple, jojoba, camellia, Prynne (Southern), azalea, wax plum, plum blossom, Milan (south) and so on. If the branches are circumscribed and scratched, smear 100ppm to 200ppm ABT rooting powder (No. 1 or No. 2) liquid, and then wrapped in mud moss, etc., to facilitate the healing of the girdling part.
(III) Management of Balcony Potted Flowers 1. Regardless of the north and south of the basin, as long as the temperature on the balcony reaches 10°C to 15°C, most of the potted plants can be moved to the balcony, but before the room is out, there must be a process of exercise adjustment. Regardless of whether it is evergreen or deciduous species, as long as the potted plants have not yet germinated or germinated, the pots can be changed at this time. Usually the pots are changed once a year, and the large pots are changed every 2 to 3 years. The common types of flowers that can be changed in April are: Pittsburgh, Milan, Zhulan, Jasmine, Rubber Tree, Monstera, Spring Feather, Camellia, Plum, Waxberry, Begonia, Clivia, Foliate, Araucaria, Schefflera Chai, Bougainvillea, beautiful needle acorn and so on. In general, when changing basins, some yellow or chaotic leaves and branches must be removed and some of the old or decayed roots should be cut off. White orchids change basins, and even the remaining part of the old leaves should be removed to facilitate the promotion of new leaves.
In April, the potted potted plants on the balcony were: Wujiao Pepper, Petunia, Calendula officinalis, Hexaphyllum serrata, Hualingcao, Hippeastrum (Balloon), Iris, Marigold, Dahlia, and Mosaic.
2. Pruning to Rhododendron, Camellia, etc., after flowering, remove the buds and buds in time, and slightly cut the branches and branches of pests and worms. After the flowering, the plants such as waxberry, plum, blue peach and golden bell, etc. The annual branch retains only 1 cm to 2 cm of the base, and all other parts are cut off. For pineapples, Cymbidium, etc., it is necessary to cut off the remaining stems in time after flower failure, and then give a change basin. Careful attention should be paid to the removal of pecans from Clivia, and it is very easy to cause the plants to be rotten. The method is to stop the water in the basin for a week to dry it, and not to cut the juice after the flowers are damaged. Into the leaf tube, the pot can be tilted in advance, control the water, until the wound is dry and then correct the flower pot, to avoid dirty rain, dirty water, Lin Lin, so that the natural dried flowers shriveled wither.
3. Watering In April, the potted flowers on the balcony should be kept moist, with more water spray and controlled watering. Because the temperature is still low at this time, must not cause excessive rooting of the plants due to watering. When the temperature rises to about 20°C, increase the amount of watering. Generally, it can be poured once a day. A small number of potted flowers that are placed in the room can be sprayed with cold water, but the remaining tea leaves cannot be poured into the pots.
4. Fertilizer Potted flowers and fertilizers on the balcony should be used with special care. Do not use types with strong smells and odors. This is not conducive to the cleanliness of your own balcony, but also affects the relationship with your neighbors. You must not go as you like. Balcony cultivation can be used after the maturity of dried organic fertilizer particles, long-effective multi-component composite fertilizer, bar fertilizer and urea and potassium dihydrogen phosphate solution. The general principle is: NPK balance, thin fertilizers, inorganic organic fertilizers, and avoid using raw fertilizer, concentrated fertilizer, and large fertilizers.
5. Insect Pests In mid-to-late April, freshly-emerged whitefly adults will appear on plants such as oysters, kumquats, bergamots, etc., and can be sprayed with pesticides such as chlorfenadone and phytosteril to kill them. For leafy plants, such as a leaf orchid, rubber tree, cycads and other parasitic plants on a small scale insecticide, should be promptly wiped with a damp cloth or stick with transparent tape. For rose plants, Bordeaux mixture can be sprayed every other month to prevent black spot and other diseases.
