What to pay attention to when growing flowers in high summer temperatures
If you want to know what to pay attention to when growing flowers in high summer temperatures and detailed introductions to the precautions for growing flowers in hot climates, let's take a look together.
In the hot season, plants are particularly susceptible to various diseases and pests, including common pests such as whitefly, small black flies, scale insects, aphids, and thrips. There are also many common diseases in summer, including powdery mildew, root rot, and black spot disease.
The above is purple leaf oxalis, which needs to be properly shaded in summer, otherwise the leaves will be sunburned.
In summer, potted plants on the balcony at home are prone to withered and yellowed leaves, and for potted vegetables and fruits, such as tomatoes and cucumbers, it is easy to have僵果.
If you grow flowers on a closed balcony, indoor potted plants are prone to breed small black flies, which will fly around everywhere, and these pests can even bite people. Indoor flower cultivation is also prone to red spider infestation, which can easily break out in summer.
Now I will teach you the simplest handling skills, which you can refer to appropriately.
1. Pruning and cleaning
Never expect the withered and yellow leaves of the plant to stay on the soil surface to slowly turn into nutrients absorbed by the plant.
These dry fallen leaves will not become fertilizer but will become a breeding ground for diseases and pests.
Especially some diseased leaves and branches, after falling on the soil surface, can carry pathogens. Common small black flies especially like decayed leaves and roots.
Hydrangea should be kept in a semi-shaded place in high summer temperatures, with proper shading in the afternoon (remove spent flowers after blooming).
If leaves turn yellow and wither, withered leaves, diseased branches, and dry branches should be pruned clean. After the flowers have finished blooming, the spent flowers should also be cut off to prevent excessive water loss and allow the plant to grow new buds as soon as possible. Be careful not to cut too hard at once, and avoid rainy weather or getting the wounds wet.
2. Enhancing ventilation and shading
In the season of high summer temperatures, most plants cannot tolerate the intense afternoon sunlight, especially for plants that have been kept indoors for a long time. Of course, for plants that are accustomed to outdoor cultivation, especially those that are heat and sun-resistant, that's another story.
For various potted plants on the balcony, if it rains during the rainy season, especially in hot and humid weather, be sure to avoid rain appropriately.
In other sunny high-temperature seasons, pay attention to opening windows for ventilation, which can not only release heat but also prevent stuffiness, leading to diseases like powdery mildew and red spider infestation.
In environments with poor ventilation, red spiders are particularly prone to outbreaks, and plants are also prone to powdery mildew, so early prevention is necessary.
Flower friends with conditions can hang a small fan next to the potted plants, but not directly facing the plants.
3. Reasonable watering and stopping fertilization
In excessively hot weather, the soil in potted plants dries up quickly, so it is necessary to supplement water in time and not let the soil dry out too much. Similarly, if it is rainy, avoid keeping the soil continuously moist.
In the season of high temperatures, avoid excessive fertilization or too concentrated fertilizers. For heat and sun-resistant plants that are still growing in summer, you can apply a lower concentration of fertilizer, reducing the fertility by half or more, and also reduce the frequency of fertilization.

The above is the medicinal golden枝玉叶
If plants have entered dormancy in summer, including various succulents and geraniums, which have stopped growing new leaves and roots, it is necessary to temporarily stop fertilizing. For plants that have stopped growing, fertilizing will not promote growth but can cause the plant to absorb excess nutrients, leading to root burns and causing fertilizer damage.
4. Controlling small black flies
If your potted plants have been infected with small black flies, it is necessary to control them in time. You can hang yellow sticky traps nearby to prevent the soil from staying moist (dry the potting soil as soon as possible). You can cover the soil surface with a layer of dry pearl rock or fine sand and then supplement water through the method of soaking the pot. Do not let the soil surface stay moist, which can prevent small black flies from laying eggs in the soil.
The above is rock core, which basically stops growing in summer.
5. Preventing diseases and pests in advance
When growing flowers, it is necessary to prevent diseases and pests in advance, rather than waiting for the plants to be infected before applying pesticides, which will be less effective and difficult to kill the pests, especially when the infestation is severe.
The above is Catharanthus roseus
The simplest method is to bury systemic insecticides and fungicides, such as common small white and small pink medicines, around the edge of the potting soil in advance. If you don't want to buy these systemic insecticides and fungicides, you can choose organic ones, such as plant essential oils (such as orange peel oil) or neem oil.
The above-mentioned sharing on what to pay attention to when growing flowers in high summer temperatures and detailed precautions for growing flowers in hot climates is for everyone's reference and operation.
