Lagerstroemia indica old pile will not bloom for three years.

The most explosive rose seedlings are 3-5 years old. If you plant them in flowerpots, they will get better in 2-3 years. Of course, roses will also age. You don't have to pursue "ten-year-old piles" or anything like that when you buy them. It's more economical from the small seedling belt.

The aging of Chinese roses is mainly manifested in lignification of main stems, few flowers, scattered patterns and light colors ... Especially grafted Chinese roses have a life span of 3-5 years.

How to slow down the aging of Chinese rose;

1, timely pruning

In the coldest season of winter, you can cut the roses again and cut the aging branches short. If you don't want to, you can cut it to a position 10 cm above the ground, and new bamboo shoots and branches will grow in spring.

Step 2 apply fertilizer

Ross likes fat. If there is always a lack of fertilizer, the new branches will not give force, and the old branches will slowly dry up and lignify. It is best to bury winter fertilizer before germination in spring, and fish intestines-chicken manure-cow dung can be used. Growing roses can be replaced by compound fertilizer.

Step 3 cut

Roses are more suitable for cutting. It is suggested that you use a cleaner substrate, such as perlite and vermiculite, and cutting at 20-25 degrees is the most suitable. You can also try the high-pressure method, find a piece to peel, expose the white pole, wrap it in wet soil, spray water on time, and cut it off after taking root.

Hydrangea old pile

Some flower friends think that buying old piles can directly create the effect of flower wall and flower tree. For example, Huayou "Zhong Li Fung Cham" spent a lot of money to buy four old hydrangea piles for more than ten years, hoping to improve the effect of blooming.

Good health, good maintenance, leaves are ok, just don't bloom, in vain.

The so-called old hydrangea piles are mostly old plants eliminated from flower beds. Although they are strong, they are seriously aging, or they do not bloom, and even if they do, they are sparse. The best flowering period of hydrangea is 1-5 years, and it is better to buy seedlings.

How to slow down the aging of hydrangea;

1, acid soil cultivation

Hydrangea likes acid, so it is best to raise it in acidic soil to keep its active vitality. Generally, the soil in the south is acidic. Flower friends can also make acid humus soil, pine needle soil, peel retting soil and so on. Or buy peat soil and peat soil.

The soil and water in the north are very alkaline, even if acidic soil is used, it will become alkaline after watering for half a year. Remember to pour ferrous sulfate/magnesium sulfate/aluminum sulfate every 1.5-35 degrees during the growth period of hydrangea.

2. Water supply on time

Hydrangea is afraid of water shortage, and it is always dry and easy to accelerate aging. It is best to water it in time. If it is too troublesome, you can plant it slowly and rely on heaven and earth for water supply. Hydrangea will sleep in winter, so watering should be reduced, but it can't stop completely. Water it when the weather is fine and the temperature is high.

3. Frequent cutting

Hydrangea is also suitable for cutting. Usually, pruned branches can be cut off. The stem of hydrangea is sensitive and fragile, and it is suitable for cutting with fine sand, coconut bran soil and red jade soil. When cutting, it should be disinfected and sterilized, and the temperature is between 20 and 28 degrees, which is the easiest to survive.

Longevity flower old pile

The performance of long-lived old piles is that the bottom branches are lignified (brown-gray) and the leaves are reddish and sparse.

Even if the longevity flower lasts for 3 years, it is difficult to obviously feel the aging longevity flower and it is easy to raise it to death. When cutting in the same year, 0.5-2-year-old seedlings are more suitable for novices or impatient people.

Even the experienced great god thinks that the longevity and growth of the old pile are too weak, and it takes a lot of effort. The flowering is not as good as the newly cut seedlings this year. I feel very tired and don't like it. Cut the flowers after you finish them.

How to alleviate longevity and aging;

1, timely pruning

After long-lived flowering, the residual flowers should be cut off in time, and the long branches should be cut short by the way to prevent the branches from being too long and it is difficult to transport nutrients after lignification is accelerated. This is why the thick old pile loves to blossom more than the old one that bares its teeth.

2. Change the soil in time

Although immortality does not pay much attention to soil, it is best to change the soil once a year, both in spring and autumn. It is best to change it after the flowers bloom and before the buds come out. It is more suitable to use loose and breathable granular soil and saprophytic soil.

3. More cuttings

Life is easy to cut, and everyone can practice with it. Cut off branches, big or small, and put them in the soil. Spraying the soil surface every 3-5 days without watering can ensure that the branches will not die and take root quickly.

jasmine

Some people love the old pile of jasmine, but in fact, a plant like jasmine, which likes temperature and humidity, has the best cultivation in 1-3 years, and can go to heaven after 5 years with proper pruning and maintenance. The older you get, the greater the risk and the less flowers you have.

Of course, carrots and vegetables have their own tastes, and some people like the old pile of jasmine. Even if there are few flowers and bare trees in winter, they can enjoy the pile. That's understandable. As long as you have good maintenance technology, you can still raise fine products.

How to alleviate jasmine aging

1, frequent pruning

Molly is very resistant to pruning. From the end of March in spring (the temperature is higher than 15℃) to the end of autumn (lower than 15℃), the green branches should keep the length of 2-3 pairs of leaves during continuous pruning to prevent the aging branches from being too long and slow in nutrient delivery.

Step 2 keep out the cold

Molly is very afraid of cold. If it is an old pile, basically all the leaves are lost, and it is difficult to feed jasmine without photosynthesis. Novices should not challenge the old pile. Jasmine is best placed in an environment above 8 degrees, with water and light controlled to ensure a smooth winter.

Step 3 cut

Jasmine is also suitable for cutting. Usually in spring and summer, the cut branches can be inserted. Each branch has a pair of leaves (half of the big leaves are cut off), which are directly inserted into the pot soil of the mother plant and watered together with the mother plant.

cast

Although mint is a perennial plant, it is enough to keep it in a pot for half a year. It's really annoying to keep it for a long time. The branches are a little messy after lignification.

Mint is the most beautiful when it is green, and its tender taste is very fragrant. If the branches age, the leaves at the bottom will fall out, leaving only a few leaves at the top of the branches, which look a bit messy, and people will not like it over time.

How to alleviate mint aging

1, water supply on time

Peppermint likes water very much during its growing period (air temperature 15-35 degrees), so it should be watered once every 1-3 days. If it is always short of water, it will soon age, fall off and dry up.

2, more pruning

As long as the temperature is right, mint grows quickly, so it should be pruned in time to recover quickly. New branches and leaves keep popping up, and its vitality is constantly stimulated.

Even the old mint, if you can't bear to throw it away, you can cut it off like a flat head and let it grow new leaves and buds again. The pruning temperature should be above 10 degree, and it can be pruned after spring in cold weather.

3, cutting layering

In winter, mint may be dormant in cold weather. It is not recommended to plant mint below MINUS 5 degrees. In the north, you can move the mint indoors first, and then press the branches in the soil in spring, and soon there will be a large area of crawling.

pelargonium

Geranium also blooms most vigorously in 1-3 years. After the lignification became more and more serious, the growth slowed down and the flowering became less and less. It is difficult to raise geranium in hot and humid weather, and it basically depends on leaves.

The aged geranium has sparse leaves and leaves, so it is unnecessary to pursue old piles. It is more appropriate to enjoy flowers or raise new seedlings. Unless you like the shape of the old pile, you can try to keep it for a long time.

How to alleviate the aging of geranium

1, learn to trim

Prune geranium constantly, for example, from seedling to flowering, it is best to top it 2-3 times to make it stand out in a ball shape, so that there will be more flowers. Remember to trim the residual flowers and cut off the branches that are too slender after flowering. It can also be pruned before winter and spring.

2. Get more sunshine to avoid too long.

Geranium loves the light, except for shading in summer, it should be basked in other seasons to ensure sufficient photosynthesis and prevent excessive growth, and keep the branches short and fat, so that even if they are aging, there is no problem in short-distance nutrition transportation, and it is not good for the old branches to be too long.

3. Multiple cutting

Geranium should also be cut from time to time. Some flower friends said that if the old branches are left for a long time, the new branches on them will fall directly, just because the old branches are not nutritious enough and the fault is broken. Try to cut more green branches with perlite scissors, 10-25 degrees.

Margarita/Margaret

Margaret has always been famous for her ability to blossom into a flower ball, and she is basically 1-2 years old. After more than three years, Ma Xiao became an old man, which slowed down her growth and reduced her flowering, making it difficult to improve.

If the old pile can be cultivated, it means that the technology is no problem, and it is not necessary to force it to bloom. It's not bad to have feelings and enjoy it.

But if we pursue flowering effect, we should raise some new seedlings with strong vitality.

How to alleviate Margaret's aging;

1, multiple pruning

Margaret should also keep topping and pruning, sow seedlings in autumn, topping 2-3 times in winter and early spring to promote branching, and shave her head more after flowering to keep it round. If the branches are too long, it is difficult to fully supply nutrients after aging.

2. Multiple cutting

Margaret can also be cut. Every time the branches are pruned, they can be inserted into the soil, and they can be cut with nutrient soil and coconut brick soil. The effect is also good, and the seedlings will continue to top when they grow up. ...

catharanthus roseus

Catharanthus roseus looks like a woody plant, but it is actually a herb. It's good to keep 1-2 years. It likes to blossom on new branches. If raised too old, it will gradually decline.

However, there are also great gods who cultivate Catharanthus roseus into old piles. Huayou spent 2-3 years "dreaming of backwater" and carefully cultivated several pots of old lollipops. Success requires a lot of effort and energy. Interested Huayou can also challenge it.

How to alleviate the aging of Catharanthus roseus;

1, get more sunshine to prevent wasted growth.

Catharanthus roseus grows faster, and it can bloom all year round if the temperature is right, so it needs sufficient light, so it is best to put it on Nanyang terrace, windowsill or directly expose it to the sun. If it grows in vain (slender branches), it will wither day by day once the nutrient supply is slow.

2, timely pruning

After each flowering, the residual flowers should be cut off, and the long branches should be shortened to stimulate the new branches to continue to bloom. The pruning temperature is preferably between 15-30 degrees.

3. Reproduction

Catharanthus roseus can be cut or sown, seeds can be harvested without cutting after flowering, and seeds harvested at home can also be sown, usually in spring and autumn.
