How to overwinter figs: reduce watering, provide appropriate light, and pay attention to frost protection
The fig is a highly ornamental plant, and people grow it in many regions of our country. However, like many plants, winter is also the most difficult season for figs. So how can figs overwinter more safely? There is a detailed introduction below. Now the editor will walk you through it.
I. How do figs overwinter?
If you want to know how figs overwinter, care is very important, and the care at this time is also different from that in spring, summer, and autumn. You can hardly make a single mistake, otherwise problems can easily arise, so everyone should read the following carefully.
1. Requirements for the care location
The fig is a relatively cold-intolerant plant, so when growing it in winter, you must choose a wind-sheltered, sunny place. Generally, places with temperatures below 5°C are not suitable for its growth, so everyone needs to remember this point.
2. Frost protection treatment
Regarding how figs overwinter, frost protection management is very important. First, we need to water the soil with overwintering water for the plant, which can improve the fig's cold resistance. Then use plastic bags to wrap the fig, and let it out to breathe and receive some light at noon each day when the weather warms up.
3. Watering management
In winter, figs do not have very high water requirements. You can water according to the article on how to water figs, and the editor will not introduce it in too much detail here.
4. Sunlight management
On the question of how figs overwinter, light is also a relatively important point. The fig is a light-loving plant, so it also needs to receive light in winter. However, because the weather is relatively cold, we can choose to move it outdoors to receive light at noon when the weather warms up, and promptly move it indoors at dawn.
II. Treatment of frost damage in figs
If everyone fails to follow the above methods for care and causes the fig to suffer frost damage, be sure to promptly cut off the frost-damaged branches, so that the adventitious buds below can sprout. If not handled in time, it will cause the branches to freeze and wither, so everyone must pay attention to this point.
Cold winter arrives: "care guidelines" for various plants
As the cold winter strikes and temperatures drop, the harm to seedlings is great. To ensure that seedlings overwinter safely and avoid death caused by frost and physiological drought, the care of various plants at this time is very important.
I. Winter care of trees
Trees are the backbone tree species of urban greening. Their ecological benefits, economic benefits, social benefits, and landscape functions cannot be replaced by other plants. Therefore, strengthening the autumn and winter care and management of trees is crucial.
I. Do a good job of pruning trees: Pruning trees is one of the most important measures in tree care. In autumn and winter, tree pruning should be based on the principles of tree species habits, natural tree shape, and landscape effects, so as to achieve the goals of balancing tree vigor, promoting growth, and maintaining a beautiful tree shape.
When pruning, the following standards should be grasped:
1. Reasonable and moderate pruning should be carried out on dead branches, diseased and pest-infested branches, weak branches, damaged branches, overlapping branches, drooping branches, etc., to weaken the growth of vigorous branches, promote the growth of weak branches, and reduce pests and diseases;
2. Reasonable and moderate pruning should be carried out on trees that affect pedestrian walking, block vehicle sightlines, block street signs, traffic signal signs, and surveillance networks, etc.;
3. Reasonable and moderate pruning should be carried out on trees that pose a safety impact on power and communication overhead lines;
4. Reasonable and moderate pruning should be carried out on trees that affect residents' lives and production safety due to lush tree growth;
5. Clean up vine plants that affect the normal growth of trees.
II. Cold protection: Winters in the Tianjin area are cold, dry, and windy, and some tree species have a certain risk of overwintering, so cold protection management needs to be strengthened. Cold protection measures include: spraying anti-transpirant protective agents; wrapping tree trunks with straw rope; setting up wind barriers, etc.
III. Pest and disease control: To eliminate pests overwintering in bark crevices, trees can be whitewashed. After mixing the whitewash evenly, brush the main trunk from a height of
IV. Clean up dead branches and fallen leaves: Weeds and fallen leaves are not only overwintering sites for certain pests and diseases, but also prone to causing fires in dry and windy winters. Therefore, green production waste should be cleared as it is produced, and weeds and leaves should be cleaned up at any time, which both eliminates pest and disease sources and eliminates fire hazards.
II. Winter care of shrubs
December, January, and February are the main care and management period during the tree dormancy period. Snow on branches should be removed promptly to reduce harm. For seedlings afraid of freezing and afraid of wind drying, set up wind barriers on their northwest side. The wind barriers should be higher than the protected cold-sensitive seedlings
Before seedlings sprout, carry out one overall shaping and pruning. For shaping pruning, the tree shape should be higher inside and lower outside, forming a naturally full round-headed or semicircular tree shape. For shrub pruning, the outer contour should remain clear, and the outer edge branches and leaves should be dense. Small branches in the inner canopy of shrubs should be thinned appropriately, strong branches should be appropriately shortened, and drooping slender branches and ground-level suckers sprouting from the ground should be thoroughly removed.
Clustered shrubs planted for many years should be renewed year by year by replacing aging branches, thinning dense branches in the inner canopy, and cultivating new branches. For shrubs with a main trunk planted for many years, an alternating renewal pruning method of cutting back the main branches should be adopted each year to control the crown, preventing the tree vigor from being strong at the top and weak at the bottom.
Controlling pests in winter often yields twice the result with half the effort. Winter is a favorable season for eliminating garden pests. You can dig out the pupae and cocoons of nettle grubs in the loose soil under trees and burn them in a concentrated way.
III. Winter care of flowers
Winter is a special period for flower care. At this time, sudden cold waves can make flowers very fragile. Subzero low temperatures are also fatal damage to plants. However, excessively high indoor temperatures and overly dry air can also cause flowers to die for many reasons. So how should flowers be cared for in winter? Remember these six points and your beloved flowers will surely pass through winter smoothly.
1. Do not water too much. In winter, the amount of water evaporation is small, and flower plants stop growing under low temperatures, especially as root activity declines. Too much water makes root respiration poor and can easily cause root disease, or even root rot and death. One of my pots of cyclamen developed yellow leaves, stem rot, and other symptoms precisely because of too much watering.
2. Fertilize less. When flowers reach the dormant period, all physiological activities basically stop, and they need very little fertilizer and water; being able to maintain life is enough. For all flowers that go dormant in winter, no fertilization is needed in winter. Fertilizing not only causes waste, but also harms the root system of the flowers.
3. The light intensity in winter is not high, but flowers need more light to facilitate photosynthesis and produce organic nutrients, thereby improving the plant's cold resistance; for some flowers that bloom in winter, it is also conducive to lush branches and leaves and larger, more beautiful blooms.
4. Diseases that easily occur in winter are all fungal diseases, such as gray mold, root rot, and phytophthora blight. The causes are none other than low temperature and decreased cold resistance of the plants, so the key is to work on reducing humidity, making the plants grow robustly, and improving cold resistance, with chemical control as a supplement. For pests, the main focus is preventing scale insects and aphids.
5. Because the winter air is dry. Especially indoors in the north, it is even drier because of heating. When the relative air humidity is too low, it will affect the growth of flowers. Flowers that require relative air humidity of no less than 80% include camellia, rhododendron, anthurium, orchid, spider plant, asparagus fern, Acorus gramineus, and Saxifraga stolonifera, etc. Flowers that need relative air humidity to reach 60% include Michelia alba, hibiscus, fuchsia, cyclamen, jasmine, rubber tree, Monstera deliciosa, Aglaia odorata, banana shrub, Pittosporum tobira, and cacti, etc. When humidity is insufficient, spraying water can be used to solve it.
6. Indoor temperature cannot be too high. Many flowers enter dormancy and semi-dormancy in winter and need quiet rest and full rest. Whether in a residence or on a balcony, the temperature should be controlled between 4
IV. Winter care of ground cover plants
When winter arrives, most ground cover plants begin to enter dormancy or semi-dormancy. It is necessary to do a good job of collecting ground cover plant seeds, clearing dead plant communities, and applying winter fertilizer.
This month, the East China region enters deep winter. Before severe cold arrives, for some evergreen ground cover plants that overwinter in the open field but are susceptible to frost damage, do frost protection work in advance. Generally, spread wood chips on the ground, or cover low dead plants with a layer of rice, or water appropriately to prevent freezing.
For perennial flowers whose branches and leaves have already been removed, apply fully decomposed organic fertilizer in the soil around the root crown to promote robust sprouting the next year. Between plants of woody ground covers planted at low density, deep tillage and concentrated fertilizer application can be carried out. Do a good job of summarizing the year's ground cover care, analyze experience and lessons, and formulate plans for improvement, renewal, and care for the next year.
In January, the East China region of our country is in the period with the lowest temperatures of the year, and the vast majority of perennial ground covers are in a dormant or semi-dormant state. For semi-evergreen species with a longer green leaf period, such as Chrysanthemum nankingense, after the seeds mature and are harvested in December, cut off the already yellowed aboveground parts in early January.
For land prepared for planting ground covers, on the basis of autumn plowing, use this time to apply organic fertilizers such as river mud. For woody low shrub ground covers, concentrated fertilizer can be applied in winter. If January is excessively dry, ground covers that bloom in spring and sprout in early spring are prone to freezing, so appropriate watering should be chosen at noon on sunny days. Combined with the winter slack season, operations such as adding soil or clearing ditches can be carried out on ground cover planting sites with poor drainage.
Five key points and four taboos for growing flowers in winter
Five key points and four taboos for growing flowers in winter
Because winter temperatures are low and humidity is small, rooms with heating are extremely dry, and rooms without heating are very cold and dim, which is very unfavorable for the growth of flowers and plants. Key points for growing flowers in winter:
1. Pay attention to frost protection and insulation
Now that residents' housing conditions have improved, enclosed balconies are very favorable for potted flowers to overwinter. If there is no enclosed balcony, potted flowers should be brought indoors at night. For some potted flowers that are especially afraid of cold, such as tropical orchids, bromeliads, poinsettias, and anthuriums, the nighttime room temperature should preferably not be lower than 10°C.
2. Pay attention not to water too much
In winter, the amount of water evaporation is small, and flower plants stop growing under low temperatures, especially as root activity declines. Too much water makes root respiration poor and can easily cause root disease, or even root rot and death.
3. Pay attention not to apply too much nitrogen fertilizer. In winter, the absorption capacity of flowers is not strong. Applying too much nitrogen fertilizer will increase the electrical conductivity in the pot soil and damage the root system. At the same time, applying more nitrogen fertilizer makes branches and leaves tender and reduces cold resistance and disease resistance, which is unfavorable for overwintering.
4. Pay attention to getting more sun
The light intensity in winter is not high, but flowers need more light to facilitate photosynthesis and produce organic nutrients, thereby improving the plant's resistance. For some flowers that bloom in winter, it is also conducive to lush branches and leaves and larger, more beautiful blooms.
5. Pay attention to disease prevention and pest control
Diseases that easily occur in winter are all fungal diseases, such as gray mold, root rot, and phytophthora blight. The causes are none other than low temperature, high temperature, and decreased plant resistance, so the key is to work on reducing humidity, making the plants grow robustly, and improving resistance, with chemical control as a supplement. For pests, the main focus is preventing scale insects and aphids.
Four taboos for growing flowers in winter:
First taboo: indoor temperature too high.
Many flower plants enter dormancy and semi-dormancy in winter and need quiet rest and full rest. Whether in a residence or on a balcony, the temperature should be controlled between 4-8°C (for flowers that need dormancy), and preferably not exceed 10°C. Once the temperature is high, flowers will have physiological activity, and may even sprout, wasting the stored energy, which is extremely unfavorable for growth the next year. This type of flower plants includes: Aglaia odorata, gardenia, jasmine, orange, plum blossom, fig, pomegranate, grape, hawthorn, papaya, Chaenomeles speciosa, apricot, peach, apple, honeysuckle, winter jasmine, Cymbidium goeringii, and Cymbidium faberi, etc.
Second taboo: excessive fertilizer and water.
When flower plants reach the dormant period, all physiological activities basically stop, and they need very little fertilizer and water; being able to maintain life is enough. For all flowers that go dormant in winter, no fertilization is needed in winter. Fertilizing not only causes waste, but also harms the root system of the flower plants.
Third taboo: dry air.
The environment in the north is already very dry, and when the relative air humidity is too low, it will affect the growth of flower plants.
Flower plants that require relative air humidity of no less than 80% include: camellia, rhododendron, anthurium, orchid, spider plant, asparagus fern, Acorus gramineus, and Saxifraga stolonifera, etc.; flower plants that need relative air humidity to reach 60% include: Michelia alba, hibiscus, fuchsia, cyclamen, jasmine, rubber tree, Monstera deliciosa, Aglaia odorata, banana shrub, Pittosporum tobira, and cacti, etc. When humidity is insufficient, spraying water can be used to solve it.
Fourth taboo: no sunlight.
Place flower plants in a place with good light, or put them in the sun for a period of time every day. It is best to ensure at least 3 hours of light per day, so that the flowers can grow robustly the next year. Even woody flowers that lose their leaves in winter and have no leaves must see sunlight. Leaving them in a dark place for a long time is absolutely undesirable.
