Can you spray foliar fertilizer on unrooted plants? Why?

Cuttings belong to asexual reproduction, is one of the commonly used propagation means of potted plants, simple operation, high survival rate, such as triangular plum, pothos, gardenia, crab claw orchid, longevity flower, tiger tail orchid, sunflower, watercress green, moon season and so on can be propagated by cuttings. Learn to propagate many flowers and plants by cuttings without repeated purchases, and you can achieve one pot into many pots by yourself!

After the cuttings are potted, it is only necessary to maintain the appropriate humidity and keep the breeding environment well ventilated, and there is no need for fertilization for the time being.

After the cuttings are potted, it generally takes about half a month to take root smoothly, and the nutrients of the cuttings themselves are mainly consumed before rooting.

If there is no rooting, it means that the normal growth and metabolism has not begun, so there is no need to fertilize or spray foliar fertilizer, but only need to be placed in a well-ventilated astigmatism environment to maintain the potting soil slightly damp.

If the substrate of cuttings is loose and fertile enough, it does not need to be fertilized even for a long time after survival.

Do the following points well, which is conducive to improving the survival rate of cuttings:

1. The quality of cuttings is the premise of success

The quality of cuttings directly determines whether the cuttings can survive smoothly, the cuttings should neither be too old nor too tender, the branches that have been completely lignified are often not easy to take root, and the branches that are too tender are easy to wilt; 1-2-year-old shoots are the best, and those with bud points or aerial roots are required to retain intact bud points or aerial roots as much as possible.

2. The cuttings soil should be loose and breathable

Cuttings propagation requires good drainage and air permeability of cuttings substrate, such as sandy loam, peat, vermiculite, maifan stone, etc. are good cuttings substrate, with good water retention and air permeability, which is more conducive to rapid rooting.

3. Cuttings need a suitable ambient temperature and humidity

Cuttings should be carried out at an ambient temperature of 15-30 °C, and too high and too low ambient temperature is not conducive to rooting. After the branches are potted, it is necessary to keep the potting soil slightly damp to avoid direct sunlight, and scattered sunlight is the most conducive to rooting.

4. Whether the cuttings can survive or not is inseparable from the correct maintenance

Although different potted plants have different rooting rates, the most important thing is that they are inseparable from proper maintenance, especially humidity control, and about half of all cuttings failures are due to rotten roots and stems caused by frequent watering.

With the smooth rooting of cuttings, we must gradually reduce watering and increase light, so that the potted plants from cuttings will be healthy and full, especially succulent plants such as tiger tail orchid, longevity flower, crab claw orchid, etc., if water accumulates in the pot for a long time, even if it takes root smoothly, there will still be rotten stems and rotten leaves in the later stage.

Summary: Cuttings belong to low-cost propagation, mainly using the reproduction and regeneration ability of plant vegetative organs to reproduce, and it does not have the role of nutrient absorption before rooting, so we don't have to rush to fertilize. Even if it has been successfully rooted, the root system is not developed at first, so it is better to maintain it for a period of time and wait for the branches and leaves to flourish before fertilizing!

Foliar fertilizer should not be sprayed, because the roots of the plant are not formed at the time of cuttings, the leaves are all pruned, and the absorption capacity is very poor. Cuttings mainly rely on the nutrients accumulated in the cuttings** to grow new branches and leaves at the plant growth point and differentiate new roots from the cambium layer.

There are many ways to plant planting, and the common methods mainly include sowing, cuttings, striping, branching, grafting, etc. Among them, the cuttings method is more widely used. This is because by planting by cuttings, the cost of seeds can be saved, the growth rate can be accelerated, and the survival rate after cuttings is also high.

Cuttings do not require fertilization. After the plant has taken root, it is necessary to consider the proper application of some fertilizer. At this time, the main thing is to apply some thin fertilizer, and it is best to use liquid fertilizer.

In addition to fertilization, watering, sunbathing, and weeding should be done well after rooting. After the cuttings are planted, they should be watered in time, and they will take root after about 15 to 20 days, such as cosmos and zinnia. Most plants prefer full sun, so be sure to plant in an area where the sun is not obstructed.

After the plant takes root, there are often some weeds around it, and it is best to use manual weeding, if you spray herbicides rashly, the seedlings may also be harmed.

1. Liquid fertilizer is mainly used for fertilization after rooting

When making plant cuttings, it is best to use plain soil, i.e. soil without any fertilizer. When fifteen to twenty days have passed, the plant has taken root and in order to promote growth, fertilization is carried out. It is best to use thin liquid fertilizer, that is, dilute the liquid fertilizer with water and sprinkle it in the soil.

2. It is important to maintain moisture

Plant growth is inseparable from a moist environment, which should be watered promptly after the cuttings are planted and kept moist for several days in a row to promote rapid rooting. Most cuttings are planted in the summer months of May and June, when temperatures begin to rise and the amount of watering is increased in hotter weather, preferably twice a day.

3. Ensure sufficient sunlight and timely weeding

Most plants prefer a sunny growing environment, so be sure to choose a sunny and unobstructed area when cuttings. After the plant takes root, there will also be a lot of weeds around, so it is necessary to weed it in time. But because the cuttings are still very weak, it is not recommended to spray the drug directly to control the weed, but should be weeded by hand.

Generally speaking, the seedlings that are cut into the living, if they are cuttings in the hole tray, can be transplanted after rooting, but the water and fertilizer management can also be temporarily strengthened, so that the root system grows slightly more vigorously in the hole tray and then transplants the survival rate is higher, because the root system holds the soil in the hole tray into a soil ball, and the transplanted soil ball is not easy to scatter and not easy to hurt the roots. So I cuttings of the month, from the bottom of the hole disc to see that after rooting, I will do three points, first, watering will add water-soluble fertilizer, so that can meet the root system's demand for nutrients, but because the root system is weak, the concentration should be controlled, the second strengthens the light, reduce the humidity, many cuttings of the environment light is weak, which is not conducive to photosynthesis, strengthen the light can quickly make the seedlings strong, reduce the humidity can improve the resistance of the seedlings, but also reduce the occurrence of diseases, the third spraying drugs, Generally, it is sprayed with broad-spectrum fungicides, especially the seedlings that have just been cut into life, the new leaves are very tender, especially easy to get sick, and for small seedlings, once sick, it is almost fatal. No matter what kind of flowers are cuttings, it is basically such a management routine.

Generally speaking, there is no need to fertilize after rooting, but if the growth is not very good, it can also be moderate, but use some slow-release fertilizer, not too much.

After the cuttings of the plant take root, it is necessary to fertilize, at this time fertilization can allow the plant to fully absorb nutrients, help the plant to grow strongly, and the roots will rise stronger.

Is it a spray of foliar fertilizer? If yes, then it is definitely not allowed to be watered in the roots. If it's not foliar fertilizer, you can.

Plants absorb nutrients, mainly through the root system, and generally fertilization is done in the developed part of the root system. Leaves are responsible for photosynthesis, and foliar fertilizer is a foliar fertilizer that directly applies the nutrients required by crops for the purpose of foliar absorption, which is called foliar fertilizer.

Foliar fertilizer is a type of fertilizer that is applied to the surface of crop leaves with nutrients, and plays its function through the absorption of leaves, the leaves of plants have two layers of epidermis, composed of epidermal cells, and the outer side of the cells on the surface has cuticle and wax, which can protect the mesophyll cells under the epidermal tissue to exercise photosynthesis, respiration and other functions, and is not affected by changes in external adverse conditions. Studies have shown that the cuticle is composed of a long carbon chain fatty acid polymer with hydroxyl and carboxyl groups, and the molecular interstitial space of this polymer and the hydrophilic groups of hydroxyl and carboxyl groups on the molecule can allow the aqueous solution to penetrate into the leaves.

Urea substances in chemical fertilizers have a softening effect on the stratum corneum of epidermal cells, which can accelerate the penetration of other nutrients, so urea has become an important component of foliar fertilizer.

Not because it pollutes the leaves of this tree, and some fertilizers can only do their job in the soil. If sprayed on his pages, it will cause its leaves to rot, which will make a dead plant unable to regenerate.

No. Fertilizer sprinkled on the surface of the leaves causes the breathing holes on the surface of the leaves to not breathe smoothly, and yellow leaves are likely to appear, so the correct way is to put the fertilizer into the soil.

This is not recommended for the following reasons:

1. When cuttings, because the roots of the plant have not yet formed, all the leaves are cut off, and the ability to absorb nutrients is very poor.

2. Cuttings mainly rely on the nutrients accumulated in the cuttings**Plant growth points to grow new bark branches and leaves, and the cambium layer differentiates new roots. Therefore, it is not possible to absorb foliar fertilizer when cuttings.

3. If the concentration of foliar fertilizer is large, it will play a bad role in changing the group, because the water potential outside the cuttings is low after spraying, and the water in the cuttings will flow outward, affecting the absorption of water.

It is recommended to soak the branches with rooting agent to promote rooting, and then spray appropriately to promote growth after the roots and new leaf cover grow.
