Today is the first day of October and the National Day of our country. October contains the two solar terms of cold dew and frost in the twenty-four solar terms. During this period, the temperature further dropped, the temperature difference between day and night was large, and most of the garden plants began to slowly fall leaves, and gradually entered a dormant or semi-dormant state to prepare for safe wintering; except for a few diseases and insect pests that are still harmful, most of the pests and diseases have also begun to look for a place to overwinter.
However, the garden maintenance work in October is still very heavy, in addition to daily management, it mainly includes the prevention and control of diseases and insect pests, the development of autumn planting work, and the preparation for the safe wintering of plants. The specific work content that needs to be done, I have made a simple summary for you, I hope to help you a little!
The daily basic work in October mainly includes plant pruning, green space finishing, watering, fertilization, pest control, etc., and the specific work content is as follows:
1. Pruning of garden plants

For the autumn pruning of garden plants, I have briefly summarized it in the articles of the previous two days, and the specific pruning methods of different garden plants and the pruning time can refer to my previous articles:
"Different garden plants, the pruning method of autumn pruning is different, are you pruning correctly?" 》
What needs to be emphasized here is:
For hedge plants such as red leaf heather and Golden Virgin, in addition to maintaining a better shape, there is also a purpose to promote its germination of more new shoots, so the pruning work of hedges and so on generally begins in early September and ends in early October;
For the long-term flowering plants planted in the moon season, Ziwei and other places, it is mainly to prune some residual flowers, and simply reduce the branches without pruning too much, because winter pruning will be carried out after the leaves fall;
The lawn mowing ends in October, and the last time the height of the grass can be appropriately raised, which helps the lawn to overwinter safely.
2. Clear the garden, plough and sort out
The picture shows the opening of trees and the loosening of soil
For the fallen leaves, dead branches and dead grass in the park, it is necessary to clean up in a timely manner to reduce the wintering places such as diseases and insect pests;
For root grass and flower plants such as grass, jade hairpin, caryophyllus, peony, etc., when the aboveground part dies after the frost falls, the dead branches and leaves should be removed in time to avoid the overwintering of diseases and insect eggs.
For lawns, trees, flower beds, etc., it is necessary to cut edges, open and plough in time.
3. Reasonable watering
The picture shows watering green plants
Autumn is another peak growing season for most plants, and at this time there is more wind and less water, so there is often a lack of water for open-ground plants.
In the daily management, it is necessary to check in time, when the soil is found to be dry, it is necessary to replenish the water in time, and pay attention to being watered well and thoroughly.
4. Fertilization in autumn
The picture shows the decomposed organic fertilizer
Regarding the fertilization work in autumn, I also briefly introduced it two days ago, and friends who want to know can refer to my previous article:
Why is it said that the fertilization of garden plants should be "light application of spring fertilizer, skillful application of summer fertilizer, heavy application of autumn fertilizer"? 》。
Here I would like to emphasize two main points:
The first point is that autumn fertilization must be based on organic fertilizer. Because the fertilizer effect of organic fertilizer is more durable, and organic fertilizer can improve the physiological structure of the soil, make the soil more loose and breathable, and also improve the water retention capacity of the soil, as well as the temperature of the soil, which is of great significance for the safe overwintering of plants and the alleviation of spring drought in early spring.
The second point is that if the local autumn temperature is too high, afraid that the plant will grow after fertilization, which is not conducive to the safe overwintering of garden plants, the autumn fertilizer application time can be appropriately postponed. In principle, the fertilization of autumn fertilizer in the northern region can begin after the autumn equinox, while many areas in the south do not apply autumn fertilizer.
The picture shows the green paulownia lice
In October, most of the pests and diseases begin to stop harming and preparing to overwinter, and only a few pests and diseases are still in harm. The main pests that are still endangered in October are aphids, leafhoppers, wood lice, grubs, grubs, etc.; the main diseases that are still in harm are rust, coal pollution, leaf spot disease, etc., and the specific control methods are as follows:
Pest control:
(1) Control of pests such as aphids and leafhoppers
The picture shows an aphid
In October, the harm of aphids, leafhoppers, etc. has reached another peak, and this harm is usually alleviated in November.
For the control of aphids, leafhoppers and other sucking pests, you can choose acetamiprid, imidacloprid, thiazinone, etc. for spraying, continuous spraying 2 to 3 times, the interval between each time is about one week.
(2) Control of pests such as wood lice and tick shell insects that secrete wax layers
The picture shows the purple velvet beetle
Wood lice in the garden mainly harm the green tree, pear tree, camphor tree, acacia, etc., in October is generally the last harm of the wood lice, mainly gathered on the young shoots of autumn shoots to suck the harm; and in October there are many insect shell insects are still harmful, such as purple weed velvet beetle, persimmon sponge bug, etc., they are mainly distributed in the branches of plants, or on the fruit of the harm.
The two pests of wood lice and tick shell insects have a common feature that they secrete a waxy layer, which has a certain impact on their control work; and the secretions of the insect shell insects often induce the occurrence of coal pollution disease, affecting the normal photosynthesis of plants.
In the control of pyllids and ticks, you can choose acetamiprid, thiazide, thiamethoxazine, ethyl spirant, etc., together with silicone or orange peel essential oil and other infiltrators, can make the drug better penetrate the wax layer, so as to achieve a better control effect.
(3) Prevention and control of underground pests such as grubs
The picture shows the underground pest grub
In October, the grubs enter a period of overeating, which is very harmful to the root system of garden plants. At this time, granular insecticides such as diazinphos, octyl thion, and chlorpyrifos can be selected for application, and then irrigated for control. For specific prevention and control, you can refer to my previous article:
"Control of underground pests, when to use drugs, how to use drugs, in order to better play the effect of medicine?" 》。
disease control:
The main diseases that occur in October are rust, powdery mildew, coal pollution, leaf spot disease, etc., and the specific prevention and control methods are as follows:
(1) Prevention and control of rust
The picture shows the lawn grass where rust occurs
The rust in October mainly occurred on cold-season lawns, with the most severe diseases being ryegrass, tall fescue and grass early maturing grass. Specific prevention and control methods can refer to my previous article:
"After entering the autumn, beware of large-scale outbreaks of lawn rust and avoid rust on the lawn".
(2) Prevention and treatment of powdery mildew
The picture shows the ten credits for the narrow leaves where powdery mildew occurs
Powdery mildew in October mainly occurs on garden plants such as large-leaved boxwood, moon season, yellow oak, and narrow-leaved ten merits.
Specific prevention and control methods can refer to my previous article:
"Powdery mildew is coming, don't wait until the plant is covered with white powder to prevent it, early prevention is the key!" 》
3. Prevention and treatment of coal pollution disease
The picture shows the heather leaves where coal pollution occurs
The main cause of coal pollution disease is generally caused by the secretions of aphids or aphids.
Therefore, for the prevention and control of coal pollution disease, the most important thing is to prevent insects first, and then prevent diseases, and the specific prevention and control methods can be referred to:
"Garden plant coal pollution prevention and control, spray fungicide is not effective? Try these tricks! 》。
The picture shows the transplanted trees
In autumn, the temperature is cool, the trees begin to fall leaves, and the evaporation of some parts of the trees becomes smaller, which is very suitable for the transplanting of trees. For seedlings with relatively early leaf fall, such as tung, national locust, green tung, etc., they can generally be transplanted in late October; for seedlings with late leaf fall, they generally start in November, and can be transplanted to the soil.
For the knowledge of autumn transplantation, you can check out my previous article:
Why is the survival rate of transplanted trees higher in autumn? What else needs to be paid attention to to improve the survival rate.
In October, in the northern region, preparations for the safe wintering of garden plants, especially the seedlings that have just been transplanted that year, can begin.
The wintering preparations that need to be done in October are as follows:
1. Spray plant antifreeze
This work can generally be carried out in October of the plant, it is best to complete before the plant leaves fall and yellow leaves, and after the leaves fall, you need to irrigate the roots. The effect of spraying plant antifreeze on the landscape is that it may cause premature defoliation of trees.
2. Paint the trunk white
The picture shows the trunk of a tree being whitened
The whitening of the trunk generally begins in October, and its main purpose is to eliminate the trunk and the eggs of overwintering insects in the crevices of the tree, as well as to reflect the sunlight on the trunk during the day, reduce the temperature difference between day and night, and avoid frost damage to the tree.
3. Wrap grass rope, insulation cotton, etc
The picture shows the tree wrapped in a straw rope and a film
The trees are wrapped with grass rope, thermal insulation cotton, and the base of the tree is covered with plastic sheeting and soil, mainly the antifreeze method of newly transplanted seedlings, or seedlings with poor frost resistance such as magnolia, camphor, and simple trees.
The work is generally carried out in mid-to-late October, or early November, in the cold area cold work is generally done as soon as possible, the specific cold protection measures, I will continue to introduce to you in future articles.
Well, about the garden maintenance work in October, I will briefly introduce it to you here today.
I am the headline garden lang, you can pay attention to me, every day for everyone to update the garden maintenance technology knowledge, as well as about the little secrets of plants!
