June maintenance of flowers: watering

Pay attention to watering in June

First, the watering time is 10 a.m. or 5 p.m. generally, watering once a day is enough

The second is the watering temperature, which should keep the watering water basically consistent with the pot soil temperature. If the water temperature is too different from the soil temperature, it will stimulate the roots and leaves of potted flowers and affect their growth

The third is the combination of watering and spraying. In case of weather without rain for several days, in addition to watering the basin, spray water on the leaf surface and around the potted flowers to improve the humidity of local space. If it continues to be cloudy, it is necessary to decide whether to water and spray water according to the dry and wet conditions of the basin soil

Watering method of dormant flowers

Semi dormant people, such as Oxalis sorrel, geranium, golden bell, Clivia, Calla, Begonia, etc., when the temperature reaches more than 30 ℃, due to their weak growth activity and low metabolic level, it is necessary to reduce watering and keep the basin soil moist

Deep dormant species, such as Cyclamen, Lycoris (type), Ranunculus japonicus and Dutch peony, are characterized by the withering of aboveground stems and leaves and the withering of underground nutrient fibers and roots under high temperature. If underground stems or tubers are dormant in the soil for summer, they must stop watering and move to a cool place to keep the basin soil not too dry

How to water in rainy weather

In case of continuous rainfall, the potted flowers shall be comprehensively inspected after the rain stops. If there is ponding in the basin, it shall be poured out as soon as possible, and the soil shall be loosened after the basin soil is dried to avoid plant rotten roots; Or knock down the potted flowers before the heavy rain, and straighten them after the rain stops

June maintenance of flowers: fertilization

To the vigorous growing species

Such as turtle backed bamboo, Chlorophytum, composite fruit taro, bamboo Yu, kidney fern, spring feather, iron tree, one leaf orchid, Hulk, red (green) GEM, green emperor, green queen, rubber tree, Anthurium andraeanum, red backed osmanthus, brown bamboo, Araucaria, Brazilian iron, luohansong, fortune tree, Chimonanthus praecox, rose, white orchid, Milan, jasmine, Zhulan, plum blossom, camellia, tea plum, Daphne odora, Rhododendron, Japanese osmanthus, five color plum, longtuzhu, shrimp flower, Daidai, lemon Kumquat, pomegranate, crape myrtle, Pyracantha, etc. can be applied with retted thin cake fertilizer and water every half a month. For flowering species, an appropriate amount of phosphorus and potassium fertilizer should be applied to meet their needs of growth, flowering and fruit hanging

For the species of flowers in dormant and semi dormant state

Fertilization must be stopped; Especially those fleshy flower species, such as jade leaf, crab claw, crystal palm, fairy pen, squirrel tail, pine leaf chrysanthemum, leopard skin flower and Sedum, when the temperature reaches above 35 ℃, fertilization should be stopped to avoid decay

June maintenance of flowers: pruning and bud picking

Blooming flowers

Prune the vigorous growing species such as elm, Brome, Luohan pine, Fujian tea, true cypress, green cypress, bayberry, juniper, Chinese wolfberry, holly, triangular maple snow willow, Tamarix, Pyracantha and so on. Prune or shrink the branches that affect the shape as soon as possible, so as to keep the plants in a clear-cut and good shape, and promote them to draw more short branches and new buds to form a perfect shape as soon as possible

Plants with withered flowers

When picking bud Milan, jasmine, Zhulan, rose and other flowers, the residual flowers and dead stems shall be removed in time, and the flowering branches shall be appropriately reduced and cut to promote the lower lateral branches or flower buds to bloom again; Brandy, Daidai, Rhododendron, camellia, Chimonanthus praecox, plum blossom, Begonia and other flowers and trees, in order to promote them to form a good plant shape, they should have more pregnant flowers, more flowers and better flowers in the current year or the next year. Those branches that are overgrown should be topped and sprouted to inhibit the growth of main and side shoots and promote the germination of side buds

June maintenance of flowers: shading

Shade loving flowers

In June, the flowers and trees that like shade or half shade must be moved to the shade to prevent the sun from damaging the plants. Such as Hosta, purple calyx, asparagus, camellia, tea plum, Rhododendron, Magnolia, orchid, palm bamboo, rubber tree, fern, Xilin taro, fruit taro, Fendai leaf, spring feather, green rose, green bean petal, Hulk, red (green) GEM, green emperor, red queen, dandelion, Daphne odora, monophyllum, Chlorophytum, etc

Light loving flowers

For the types of flowers that like light, sufficient light must be given, such as pomegranate, wisteria, Pyracantha, crape myrtle, jasmine, June snow, cycas, juniper, peach blossom, plum blossom, wax plum, Langyu, Fujian tea, triangular maple, sparme, Chinese wolfberry, holly, bayberry, oak, black pine, brocade pine, brandy, Milan, rose, ten meridians, grapes, etc; Luohan pine, tiger thorn, Tianzhu, fobelly bamboo, Guanyin bamboo, five needle pine, bamboo cypress, etc. can be given appropriate shade

June maintenance of flowers: pest control

① Cypress, cypress, elm, papaya, Pyracantha, Pinus grosvenorii and Begonia are vulnerable to the harm of dry eating longicorn beetles, which should be stopped with poison sticks in time

② Season, rose, rose, etc. are prone to powdery mildew and brown spot in plum rain season. It is necessary to spray Bordeaux liquid as soon as possible for prevention and control

③ Orchid, plum blossom and wax plum are vulnerable to aphids, so appropriate pesticides should be selected and sprayed as soon as possible

④ Flowers and leaves are easy to be infected with anthrax, so fungicides such as carbendazim should be sprayed as soon as possible

⑤ Hawks, lemons, kumquats, bergamot, etc. the young leaves are easy to be eaten by citrus Phoenix butterfly larvae, and can be killed by spraying contact insecticides, stomach poisons and other pesticides
