Mimosa is poisonous.
Mimosa is ashamed when touched because it contains a mimosin, which is a highly toxic organic substance. If touched, it will make people's hair fall off or cause general discomfort.
Narcissus beware of eating by mistake.
Narcissus has high medicinal and ornamental value, but its flowers contain a toxic substance called lacodine, which can cause vomiting, diarrhea and other symptoms if people and animals eat it by mistake.
Cordate telosma should not be kept indoors.
The fragrance of this flower is so strong at night that some people use it to drive away mosquitoes indoors. However, the harmful substances contained in this fragrance are also harmful to people, especially patients with hypertension and heart disease will feel depressed and uncomfortable after smelling it, thus promoting the recurrence of the disease. Therefore, when it is in full bloom, it should not be placed indoors.
In addition, calla lily, winter coral, tortoise shell bamboo, poinsettia, Lycoris radiata and lily all contain different toxic substances. Therefore, in Shang Huashi, we must understand the characteristics and toxic side effects of flowers, and do not touch them at will to prevent toxins from entering.
March flower guide
(1) Flower varieties suitable for garden planting 1. Ground-planted flower varieties If the front of your yard is wide, with good lighting and ventilation conditions, or more than 30 meters away from the front building, the soil has been improved to some extent, and you can plant some flower varieties that are more fond of light and have higher requirements for the growth environment.

(3) Garden flower management 1. Management of ground-planted garden flowers (1) Transplanting in March is the best time to transplant ground-planted flowers and trees, including plum blossom, magnolia, purple magnolia, Er Qiao magnolia, Liriodendron, red maple and so on. It should be arranged as far as possible before the plants germinate and spread their leaves; Evergreen flowers and trees should be pruned when transplanted to reduce transpiration and improve survival rate; Transplanting wintersweet, crape myrtle, bauhinia, hibiscus, horse chestnut, peach, red plum, cherry blossom, etc. Even after germination, it is harmless, but it should be trimmed properly. Both evergreen trees and deciduous trees should be transplanted with enough soil balls. Generally, the diameter of the soil ball should be greater than 6 times the diameter of the trunk.
(2) Fertilization For the ground-planted flowers and trees that are not buried with fertilizer in winter, an annular ditch with a depth of about 15 ~ 20cm can be dug before sprouting at the periphery of their roots, and cake fertilizer, manure, chicken manure, pigeon manure or multi-element compound fertilizer can be applied to lay a solid material foundation for their annual growth.
(3) Prune uncut plants, especially plum blossom, Chimonanthus praecox, Admiralty and Yingchun. After the flowers wither, except for pruning dead branches, pests and diseases, and over-flourishing flower branches, annual branches can be cut off by 2 ~ 3 cm at the base of branches, leaving only 2 ~ 3 buds. After intensive pruning, more new branches will sprout in spring, and more flower buds will be bred in summer and autumn, which is beneficial to the next year. For camellia, camellia, etc. Branches that destroy the plant shape can be pruned after flowering, while pruning some twigs and cross branches with cavities. Pomegranate, hibiscus, osmanthus, etc. Those that form buds and bloom on the new branches of the year can be pruned in March to adjust the plant shape and improve the ventilation and light transmission of the plant.
(4) Prevention of pests and diseases The branches and leaves infected with pests and diseases on plants should be cut and destroyed in time, which can reduce the occurrence of pests and diseases in that year; For some flowers and trees prone to diseases and insect pests, such as rose, horn, begonia, grapes, begonia and so on. Spraying Bordeaux mixture in time after spreading leaves can prevent powdery mildew rust.
2. Management of Ground-planted Courtyard Grass Flowers Transplantable in March include carnation, snapdragon, calendula, daisy, hollyhock, mallow, Ophiopogon japonicus, scallion, chive, iris, Reineckea carnea, Ophiopogon japonicus, Oxalis, etc. For grass flowers transplanted before February or years ago, if the plants have resumed growth, such as kale and pansy, you can first weed and loosen the soil, and then apply low-concentration liquid fertilizer, such as soaking odorless cake fertilizer water, 0.5% urea solution, or quick-acting compound fertilizer solution for flowers on New Year's Eve.
3. Garden potted flowers and trees management (1) Potted Chimonanthus praecox, Mume, Begonia pendula, Begonia longipedunculata, Pyracantha fortunei, Pinus bungeana, Bambusa bambusa, Elm, Acer truncatum, Oak, Fraxinus chinensis, etc. When placed in an open field, the pot can be changed before it germinates and leaves, and it can be replaced with loose, fertile and fresh culture soil rich in organic matter.
Suitable for indoor plants, such as Prynne, Milan, Eupatorium odoratum, Rose, Jasmine, Fusang, Hewanglan, Cycas, Poinsettia, Camellia, Tea Tree, Belgian Rhododendron, Fu Gui Seed, Zanzan, Bergamot, Lemon, Tortoise Shell, Spring Rain, Clivia, Angel, Fruit Taro and Bamboo Taro.
(2) Exercise in the area north of the Yangtze River Basin. In March, most potted flowers are still maintained indoors, and both cold protection and ventilation must be paid equal attention to. Due to the unstable weather this month, the cold current will sometimes go south, and it is still necessary to continue to do a good job of heat preservation and cold protection in early and middle March. In late March, the doors and windows of the living room can be opened for ventilation during the day and closed at night, so that white orchids, Milan, pearl orchids, jasmine, hibiscus, poinsettia, tortoise shells, cherubs, rubber trees, aralia trees, etc. can be gradually exercised to adapt to the outdoor environment and avoid problems. Potted flowers in the area north of the Yellow River should continue to do a good job of heat preservation and cold protection this month, and must not be taken lightly.
(3) Pruning indoor hibiscus, upside-down golden bell, Dendrobium nobile, jasmine, Eupatorium odoratum, cycad, rubber tree, Solanum lyratum Thunb., Chinese cabbage, deciduous wood, asparagus, begonia, etc. , combined with changing pots, pruning if necessary, including cutting off branches of pests and diseases, dead branches, disorderly branches, twigs and some yellow leaves. Branches of Acer truncatum, Podocarpus, Sabina vulgaris, Pinus taiwanensis, Pinus thunbergii, Elm, Fraxinus hupehensis, Oak, Runnan, etc. Those who mainly appreciate stumps can also be trimmed before germination in March to further improve their shape. Plum blossom, wintersweet, Chinese rose, peach blossom, Spring Festival, Admiralty, etc. Strength cutting can be carried out before germination.
(1) Flower species suitable for balcony planting. It is impossible for city residents to have a small courtyard and live on the first floor. They have a good environment for growing flowers, and more often they plant some ornamental plants with strong resistance on the balcony to decorate their rooms, improve their living environment and create an atmosphere of returning to nature.
Ornamental plants suitable for planting on balconies are drought-tolerant plants, whose body surface or cuticle proliferates, or are covered with wax, or the plants are succulent, or have small leaves, which are transformed into needles, which rarely consume water for transpiration, or are native to arid desert areas, and can withstand wind and heat baking, so they are very drought-tolerant, such as cycads, cacti (yellow hairy palm, mountain shadow boxing, Qingsonglong). There are Chimonanthus praecox, Spring Festival, Lycoris radiata, taro with silver bracts, Guangdong Evergreen, Chlorophytum and so on. These flowers are usually not watered for two to three weeks in spring and will not cause death. It is more suitable to plant them on the balcony. There is also a kind of flowers that are more resistant to sun exposure and dry and hot wind, can receive enough sunshine and endure short-term extraordinary high temperature, and are also suitable for potted on balconies (especially high-rise balconies), such as pomegranate, rose, banyan, Chinese cymbidium, Ligustrum lucidum, agave, Zhu Dinghong, Bromus, oak and so on.
Elm, Acer truncatum, Myrica rubra, Pinus thunbergii, Sabina vulgaris, Ilex cornuta, Vitex negundo, Buxus buxus, Persimmon, Sunflower, etc. In addition, jasmine, Eupatorium odoratum, Pinus pentaphyllum, Milan, Eupatorium odoratum, bergamot, lemon, rubber tree, hawksbill bamboo, spring feather, tea tree, Liriodendron chinense, Taxodium ascendens and so on. Potted plants can also be planted on the lower balcony, but water and shade management should be strengthened.
(2) The propagation of potted flowers on the balcony is suitable for potted grass flowers on the balcony, such as a bunch of safflower, five-color pepper, winter coral, marigold, impatiens, Petunia and so on. At this time, shallow pot sowing and seedling raising can be carried out.
If a small amount of asparagus and Clivia seeds are collected, they can be washed and sown indoors first, and then moved to the outdoor balcony for cultivation when the outdoor temperature reaches about 65438 05℃.
Succulent plants, such as Lingjianlian, Epiphyllum, Yushu, Gemstone Flower, Lycopodium, Portulaca oleracea, Coral Tree, Qingsuolong, etc. At this time, you can use plain sand or clean sandy loam to cut indoors and move to the balcony after spring is warm.
Loose sandy loam is filled in a large flowerpot, or vermiculite and perlite are used as cutting substrates to propagate seeds of Gardenia, Hibiscus, Bougainvillea, Podocarpus, Pomegranate, Begonia, Nandina domestica, Daphne Daphne and Fu Gui. There is good light in the indoor window sill, but the spout should be covered with plastic film for moisturizing.
On the balcony, five-needle pine, brocade pine, plum blossom, longevity peach, red maple and wintersweet are grafted. It should be bagged and moisturized, otherwise it is not easy to survive.
(3) balcony potted flower management 1. Ornamental plants suitable for balcony potted plants are mostly indoors in March. While taking measures such as heat preservation and cold protection, ventilation and light avoidance, the plants that need to be replaced should be replaced in time. Flowers and trees placed on the balcony with strong resistance should prevent the basin soil from freezing. If the potted soil freezes, it is easy to cause the potted flowers and trees to be frozen and pulled out, which not only affects the normal growth of the plants in that year, but also causes the plants to die in serious cases. You can take shelter from the rain on the spot, or you can move them indoors or in sheds to keep out the cold.
2. Pruned stumps such as Chimonanthus praecox, Ilex pubescens, Pinus thunbergii, American ginseng, Podocarpus, Elm, Mume, Myrica rubra and Ligustrum lucidum can be trimmed and shaped. Trunks and branches that need modeling can be modeled in March, and plants that have not changed pots for 2 to 3 years can change pots. The bonsai placed on the balcony should be watered every 3 ~ 5 days to keep the soil moist and sprayed with water properly. Plum blossom, Spring Festival, Admiralty, Chimonanthus praecox, peach blossom, camellia, etc. Pruning can be carried out after flowering to maintain its good plant shape, and the plants should be thoroughly cleaned, and the branches and leaves infected with pests and diseases should be cut off and destroyed; For the dry part of the stump, stone sulfur mixture can be used for anticorrosion treatment.
3. Preparation facilities If conditions permit, you can also build a small pool on the balcony to support a hard board (prefabricated with cement and steel bars), and use the humidity generated by the pool to put some flowers that prefer air humidity on it in summer, such as orchids, turtle back leaves, Hulk, angels, Fukiko and Nandian bamboo. Among them, water storage is the most suitable for watering flowers.
In March, before the potted plants leave the house, you can set up a ladder shelf on the balcony to place the potted plants, and choose the support point for hanging the sunshade net in summer. Once the potted plants leave the house, they can quickly put the shading measures in place.
In March, we should also prepare the culture soil for changing pots and all kinds of fertilizers and pesticides to meet the needs of planting flowers on the balcony for one year.
