It’s easy to have some difficulties when raising flowers in summer. It’s not a big problem when you see yellow leaves, fallen leaves, and withered flowers. Flowers have a strong survival ability. But don’t think they are going to die. You can save them in a few simple steps.
Gardenia turns out yellow, bald, but you can sprout it.
Many flower lovers like gardenias. They buy gardenia potted plants with flower buds. Few days after bringing it home, the flower buds have not opened, and the leaves are gradually yellow… Don’t panic. You can turn the situation around.
Lighting and watering of gardenia
Gardenia potted plants are usually cultivated in greenhouses. When you get home, don’t expose it to the sun immediately. It would be best to first adapt to the environment and put them in a bright astigmatism position. You can’t expose to the sun immediately and don’t be too dark. The soil should be dry and water in time. After watering, you should keep it ventilated and not be wet all the time.
After 2-3 days, gradually move the Gardenia to the position of sufficient light. Gardenia likes light. Lack of light may also drop bud, and leaves become dim and yellow. After the light is enhanced, make sure to water in a timely. When the water is short, the leaves will dry up and curl, and the flower buds will fall out.
Of course, you should also pay attention to other matters, such as too much water, no ventilation, rainy days, and other problems. If the humidity is kept too high for a long time, the edge of Gardenia leaves will fester. Also, the flower buds will rot away. At this time, we need timely ventilation. If it is serious, you need to replace the soil.
Supplement acid, fertilizer, and water
Gardenia likes acidity. It is easily growing yellow leaves if the water and soil are alkaline. If you water too much alkaline water, the leaves will turn yellow (the vein is green). You can add 1-2 drops of white vinegar to ease the problem. A more scientific way to add an acidic nutrient solution is to add ferrous sulfate once or twice a month.
Trim the gardenia plant if the leaves getting yellowish or week
If the gardenias lose their leaves or buds inexplicably, and you can not find any reason, it may also be because they cannot adapt to the environment for a while. Or maybe the plants are hormone seedlings in the greenhouse.
Once the hormone period has passed, they will not be able to support them. You can cut the withered branches, Keep healthy branches, and new shoots will emerge in places where the light is scattered.
Kalanchoe flower has changed like this; can it still be pensionable?
There are still many problems with the kalanchoe of flowers in summer. It is either dormancy or insect disease. Take care of it carefully and pass this level. After that, the autumn and winter will be wonderful.
What is dormant of a kalanchoe plant
The performance of dormancy is that the growth of kalanchoe plants is slow or even stopped. The growth of new leaves is obviously not felt, and the old leaves begin to turn yellow slowly. This is the normal metabolism. You can cut off the dense old leaves and weak branches. It will make it easy to spend the summer.
In addition to proper pruning, dormant kalanchoe should not be exposed to the sun. Otherwise, it is easy to dehydrate and dry up. You must control water, and it should be less than before. It is better to be drought and not flooded. Also, it needs more Ventilation to avoid rotten roots.
If kalanchoe is really dry, watery, and black, just slightly cut off the necrotic part. Remember to sprinkle carbendazim on the wound to prevent bacterial infection. If it is serious, You can only keep a section of healthy branches for re-cutting.
Insect diseases of Kalanchoe flower
Kalanchoe flower is a succulent plant. If insects grow in summer, they are mainly scaling insects and leaf miners. Scale insects are small white spots that stick to the leaves. When you pressed it, you can see there is a liquid. To repel these insects, you need to spray with alcohol (concentration 25- 50%) or wipe it with a cotton swab or brush dipped in alcohol.
Leaf miner moths
Leafminer moths are the most hateful. It will get into the leaves and stems, gnaw on the inside, and finally leave only the empty leaves. From the outside, you can only see small black particles, which are their feces.
If you find an empty leaf or a black insect worm, you can look at kalanchoe in the bright light. If the leaf has a transparent spot, that is basically the mark of it chewed. You can find the position of the insect, pinch it off. Other than you can spray some medicine that specifically kills soft larvae.
The rose is getting more and more crippled. You need to regain confidence
After the rose blooms, it’s basically hot in summer. At this time, if it’s not well raised, it’s getting thin and weak + diseases and insect pests. These two points will be very painful to you.
How to rejuvenate rose plants
After the rose blooms, the most basic operation is to cut off the residual flowers, saving some nutrients. Some roses are more frequent blooms and also blooming in hot weather. If the quality of the flowers is not good, they need to cut off and don’t let blossom. They will be well restored and beautiful in autumn.
In addition to cutting flowers, you should also cut some blind buds and branches. The characteristic of these buds is that they have no bud head and only one leaf at the top. Such buds will only consume nutrition and will not bloom again. There are also some weak branches, which you should cut too.
After pruning, remember to fertilize the rose. After the flowering, nitrogen and potassium fertilizer is the main fertilizer. Sheep manure, chicken manure (refined), and melody nutrient solution can all be used the same. Once a month, you can use organic manure for 2-3 months.
Diseases and insect pests of rose plants
Rose is easy to get sick, and insect pests in summer. On the one hand, it is due to the climate. On the other hand, the plants are too thin and weak. The strong rose seedlings are resistant to diseases and do not like insects. Therefore, it is also vital to keep the roses strong as the above mentioned.
Many rose diseases, and insect pests are caused by poor ventilation in the environment. Roses planted in the ground are not easy to get sick and grow insects. Indoor potted plants are high-incidence areas. Therefore, it is necessary to open more windows for ventilation and turn on the fan for blowing. You can have a try it.
Leaf spot on roses
In case of illness, it is mainly caused by leaf spots and powdery mildew. The leaf spot is caused by bacteria growth on the rose plant. Clean up the dead branches and leaves, keep the pot clean and sanitary. Especially care the old leaves contacting the soil at the bottom. Sprinkle carbendazim, plant ash, and mosquito repellent incense ash for sterilization.
Powdery mildew of roses
In addition to ventilation, you can use alcohol (concentration below 50%) to wipe In case of powdery mildew. Wipe it every few days until the disease is destroyed. In addition to liquor, you can also apply antibacterial plasters. If you are unsure, you can try a leaf first and then continue the operation after it is effective.
Red spider on roses
Rose worm disease is also a big problem. Most intractable is the red spider. Pure milk (without cooked) mixed with 5 times water and spray on the front and back of the leaves, Repeat the spray every half an hour. You can rinse it off after 2-3 hours. Week after week, you can see there is an improvement effect.
Thrips on roses
If the top buds of the rose are curly and black with gnawing marks, It may be due to thrips. Thrips are a kind of black flying insects. They can be dispatched in the evening. You can hang yellow sticky boards beside the rose tree. That can quickly and safely stick thrips and other flying insects.
Aphids and leaf-cutting bees in the roses
There may also be aphids and leaf-cutting bees in the roses. You can spray aphids with alcohol or a high-pressure water bottle. Leaf-cutting bees are not easy to catch. If you can move flowerpots, move them somewhere else. If they can’t, you can hang windmills and cloth strips to scare them. The harm of leaf-cutting is not very harmful.
Ultimate rescue of rose
If the rose is in a mess, you can cut it bald and let it grow again. At least you should keep 1 / 3 of the height above the ground. Start fertilizing after recovery. In the early stage, use slow-release fertilizer as the mainstay. Don’t apply concentrated fertilizer and quick-acting fertilizer.
Jasmine doesn’t grow up
Jasmine is blooming in summer. If you have a problem for a while, don’t be afraid. Just deal with it a little, and you can continue to bloom.
Pruning and top dressing after flowering of jasmine
If the jasmine blooms and the flowers do not grow, it may be due to insufficient light and nutrition. The color of the leaves will be softer if the light is insufficient. If the jasmine leaves are exposed to more sunlight and watering on time, they will recover. If you don’t have enough nutrition, you can water fertilizer or spray potassium dihydrogen phosphate to help re-flower quickly.
Watering and ventilation of jasmine
When Jasmine basks in the sun, you should remember to water it on time. Lack of water will cause the leaves to dry up. Quickly watering the plant will relieve it. If the water is low, cut off the dead branches and leave the branches intact, which can grow new leaves. Remember to water them in time.
Too much watering, rainy days, and poor ventilation may make Jasmine rotten leaves and flower buds fall. Remember to have more ventilation after watering. You can water less or not even if it is cloudy. It’s not too late to water when the potting soil is dry and the flower leaves drop slightly.
Insect diseases of jasmine
When the leaves are pitted, curled up, and spider silks, they are basically red spiders. Just like roses, you can spray the front and back of the leaves with pure milk. Mix it with 5 times of water, repeat once every half an hour, and wash them off after 2-3 hours (Try not to let the milk flow into the pot). After a week, you can eliminate them after several times of continuous operations.
Trim the plant
If the jasmine leaves dry, fall off, or have serious insects, you can directly trim the head and polish the damaged leaves. Leave 2-3 bud points (about 5 cm) on the green branches. Place the light on the position. When the soil is dry, water it and increase it when new buds emerge. New shoots will be re-born by increasing light.
Fortune tree (Pachira aquatica)
Don’t worry about the situation of the fortune tree. Summer is its growth period. It can be dealt with in a few simple steps. If it recovers quickly, don’t give up easily.
Sun protection and watering of fortune tree
Try not to expose the Fortune tree to the sun. Its leaves are thin and easy to be dried into the white fiber. If it is exposed after spraying water, the position of the water droplets will become hollow. Please place it in an indoor normal bright position. Make water in time when the soil is dry, or the leaves are slightly drooping. After watering, take care of more ventilation. Then you will not be afraid of rotten roots.
What to do if the fortune tree leaves turn yellow
The leaves of the fortune trees are white and hollow, which may be caused by the sun. If the leaves turn yellow, it is likely to be muggy of the soil. If the soil is stuffy and the surrounding environment is stuffy, you need to loosen the soil. Change the soil if it does not work (loose garden soil mixed with nutrient soil). Don’t put tall obstructions around. It’s good to open more windows for ventilation or put a hole for ventilation.
Yellow leaves cannot turn green anymore. Now you can remove the yellow leaves. After the ventilation problem is resolved, they won’t turn yellow. If the tip of the yellow leaf is still wet and rotten, it may be that the water is too much, and there are signs of rotten roots.
How to save rotten roots of fortune tree
Rotten roots of fortune trees are prevalent. After the roots are rotten, you must saw off the rotten parts and leave healthy stems. First, soak in carbendazim or potassium permanganate solution for half an hour. After soaking and drying, prepare clean sandy soil for replanting. Please put it in a ventilated place. When the soil is dry, then water it. You can water less, sprout at the top, and wait for 1-2 months to return to normal.
You can treat it like this for the rotten roots regardless of the size of the fortune tree. If it is difficult, you can also leave a thinner top position or leave a branch for cuttings. Or you can leave a branch for cutting. In summer, hydroponic rooting or sand cuttings are good for rooting.
Problems with a hydrangea plant
Hydrangea is more sensitive to the environment, and sometimes it wilts suddenly, which is not a big problem, and you can easily solve it by finding the cause.
Hydrangea wilted in the sun
Hydrangeas hang their heads at noon and scorch their leaves when they are hardly exposed to the sun. I suggest that shading is better, especially for potted plants. Sunburn is irreversible, so you should move them into the shade in time. Although some areas are also exposed to the sun, the overall environment is relatively ventilated, and the underground water is sufficient. Hydrangea is more resistant to the sun.
Lack of water
Hydrangea is prone to be short of water in summer, and some plants need to be watered. You can notice hydrangea is short of water when its leaves are drooping, and the soil is dry. It can restore 2-3 hours after watering. However, it is better to keep the watering frequency well and water it in the morning and evening. Otherwise, intermittent drought will cause hydrangea to scorch its leaves and flower buds.
You should also pay attention to the other extreme, that is, too much water, too often, the soil is always wet. Hydrangea root is easy to stuffy, rotten. The signs of that are the leaves are soft, and the stems are black and rot. At this time, you need more ventilation and remove moisture. In severe cases, cut out the rotten roots and cut and plant again.
Lack of fertilizer and hypertrophy
When hydrangea lacks fertilizer, the leaves will be slender, light green-yellow. It causes due to usually lack of iron or magnesium. It is recommended to use hydrangea nutrient solution, ferrous sulfate, or magnesium sulfate. Choose a one you can use 1-2 times a month. Please do not use it during the flowering period. You can use it before and after flowering.
Start all over again.
If you feel that the hydrangea is not raised well, you can cut it and start again. Especially if the hydrangea does not come back after wilting, you can cut all the soft and collapsed branches at the top and leave 1/3 above the soil surface. Then dry and wet the soil. You can sprinkle slow-release fertilizer after sprouting and unfolding of leaves and re-bring again.
Bougainvillea not blooming, don’t worry, let’s fix
Bougainvillea is also in the growth period in summer. If problems are solved in time, they will soon return to normal and continue to bloom.
Why the leaves are sparse
Bougainvillea leaves are sometimes sparse. It happens because of lack of light, too much water, and not enough nutrition. Bougainvillea loves light. It would be best if you gave it more sunlight. Normally leave the soil dry. Do not water too much. It is wise to apply regular fertilizer during the growing season. Generally, You should select the same type of nutrient solution.
Bougainvillea not blooming
There are two reasons why bougainvillea does not bloom. It may be due to insufficient sunlight and insufficient phosphorus. You can spray potassium dihydrogen phosphate solution on the front and back of its leaves. Spray once every 10 days, stop after flower bud emerge. Also, make sure to supply good enough sunlight.
Bougainvillea leaves are wilting
If your bougainvillea always lacks energy, which may be caused by water shortage and soil hardening. Although bougainvillea is relatively drought-tolerant, when the soil is dry and the leaves droop downward, it is already a signal of water shortage. So keep water it in time.
If the soil is tough and cannot pour the water well, the bougainvillea will be bitter. You can water the bougainvillea by using the sitting pot method. After the flowerpot sits in the water basin for 20-30 minutes, take it out and let the bougainvillea drink full. If it doesn’t work, you can also replace the loose garden soil or leaf mulch.
Cut and reshape when bad growth of bougainvillea
Bougainvillea tree elongation is not ideal. If so, you can trim the tree. The bougainvillea is woody and centered on the main pole. You can trim it according to the shape of the big tree and make bonsai. Shorten long branches and cut unwanted branches. Once the pruning is complete, the new leaves return to normal. After that, you can start applying fertilizer. Then the tree will be fresh.
Elephant bush (Portulacaria afra)
Summer is the most difficult time for succulents. Take elephant bush as an example. Don’t worry if the following problems occur. They can all be saved.
Falling leaves of elephant bush
The hot drop on the leaves of elephant bush may be caused by nutrient deficiency after dormancy. If a small part of the leaves is normal, pay attention to shading and ventilation. When the leaves are wrinkled, supply water immediately.
Dry of elephant bush
If the elephant bush leaves are dry, which may be due to severe sun exposure or lack of water. It is good to have more sun in spring and autumn. When the sun is hot in summer, pay attention to shade. Otherwise, the branches and leaves will quickly become dehydrated and dry.
Succulents such as elephant bush are dormant in summer. Dormancy is a process, but not 100% dormancy. Here you should reduce the water. When the soil is dry, or the leaves are soft and wrinkled, pour water on time. Then be sure to strengthen the ventilation.
Use chemical water for black rot
When water stays in the elephant bush, the stems turn black and rot. The leaves of the elephant bush fester and turn water, and the stems are black and rot. Here you can slightly remove the neurosis leaves. Then clean the wound. You can use carbendazim powder or daphnetin for sterilization. If the root system at the bottom is also rotten, it should be dug up and cut off. Leave the healthy branches and cut off the other branches.
Succulents in summer are easy to die. But as long as you keep a leaf, you can reproduce another one after summer, so don’t give up. Plants have very strong in life. Give them another chance
