If pests are found on plants outdoors, they can be killed by spraying dimethoate and dichlorvos.

Here is a simple and effective method, this method can greatly reduce indoor pesticide pollution, and the insecticidal effect is very good.

The specific methods are as follows: the mixture of dimethoate and dichlorvos was diluted 30 to 50 times and irrigated into the semi-dry basin soil. Because the indoor pot is planted in the pot, the root is concentrated in the pot, so the absorption effect is very good. By filling the pot, the liquid is absorbed by the root and then quickly transported to the leaves through the stem catheter, so that all the pests on the leaves die within 2 days.

How the northern potted flowers survive the winter safely indoors

Cyclamen

China Garden Network, January 5 news: many of the potted flowers cultivated in the north are tropical or temperate and like warmth, so they need to move indoors one after another in late autumn or early winter. The location after entering the room should take into account the habits of all kinds of flowers.

Flowers that usually bloom in winter and spring (crab claw orchid, cyclamen, melon and leaf chrysanthemum, poinsettia, camellia, etc.) and grass flowers sown in autumn (carnation, goldfish grass, etc.), as well as sexually light-loving and warm flowers (Milan, jasmine, Magnolia, Fusang, etc.), should be placed on or near the windowsill where there is plenty of sunshine; some flowers that prefer semi-shade in summer and light in winter (such as magnolia, inverted golden bell, etc.) should also be placed in a sunny place. Flowers that like warmth and semi-light (such as asparagus, begonia, rhododendron, etc.) can be placed far away from the windowsill; evergreen flowers and trees that like sunlight but can withstand low temperatures or dormant flowers (such as sweet-scented osmanthus and citrus) can be placed in cool places with scattered light (above 0 ℃) Other flowers that can withstand low temperature or light requirements (such as potted lotus, water lily, hairpin, etc.) can be put in a cool place without light; pomegranate, rose, figs, etc., need to be frozen outside-5 ℃ for a period of time to promote dormancy, and then moved into the cold room (about 0 ℃) for preservation, no light is needed. Indoor should pay attention to ventilation, not only flowers just in time to ventilation, in the whole winter, but also in the sunny weather at noon to open windows for ventilation, which can not only reduce the occurrence of diseases and insect pests, but also conducive to the robust growth of flowers.

After the beginning of winter, the temperature continues to drop, the metabolism of flowers is slow, or enter a dormant state, requiring very little water and fertilizer, so in addition to the flowers, melon-leaf chrysanthemum and camellias that bloom in autumn and winter or early spring, as well as some grass flowers sown in autumn, in addition to continuing to water and fertilize according to the actual needs, fertilizer and water should be strictly controlled for general potted flowers.

For dormant or semi-dormant flowers, fertilizer should be stopped.

If the potted soil is not too dry, do not water it, especially the potted flowers that are shade-resistant or placed in a colder place indoors, but also avoid rotting roots and fallen leaves caused by too much watering.

Plum blossom, kumquat, rhododendron and other woody potted flowers should also be strictly controlled in winter so as not to cause young shoots to grow, affect flower bud differentiation and weaken cold resistance. Cactus and succulent plants should stop fertilizing and watering less.

When watering flowers in winter, be sure to go through the sun so that the water temperature is close to room temperature. Watering time must be around 1000, if watered in the evening, the night is cold, the roots of flowers are vulnerable to freezing damage. The indoor air is dry in winter. for some evergreen flowers that like shade and humidity, such as asparagus, Milan, camellias, Magnolia, etc., you should often spray and wash the leaves with water close to room temperature to remove dust and keep clean to facilitate photosynthesis, but spraying water can not increase moisture in the basin to prevent rotting roots. Indoor potted flowers are prone to aphids, whitefly, shell insects and other pests in the family season. Attention should be paid to prevention and control in time.
