How to accelerate the germination of old elm piles?

Elm is a beautiful bonsai material. Its stem is simple and vigorous, its bark is cracked, and it has a vicissitudes of life. It will be more beautiful if you trim it with piping. In the beautiful spring, people always like to choose some beautiful old piles, hoping to cultivate them and make them into beautiful bonsai.

However, if the old elm stump wants to germinate smoothly, it will take some effort to survive. Let's briefly talk about the method of accelerating germination.

First, in order to germinate the old elm stump smoothly, it is best to treat the root system during cultivation.

If the old elm pile can bear the original soil and the original soil ball can remain intact, so much the better. If the diameter of the soil ball is four to five times that of the rhizome, it can survive and germinate with a little care.

However, most of the old elm piles we get are bare roots, which should be treated according to the freshness of the old piles. If the excavation takes a long time, the roots are not fresh enough and slightly rotten, it should be treated in time to expose the fresh parts, and erythromycin should be used to disinfect and seal the wound in time to avoid juice outflow and bacterial infection.

Be sure to touch some rooting powder when cultivating. It is best to use sterilized wet river sand for high-level culture and cultivate embryos on the ground. Don't water for the time being, so as not to water too much and rot the roots.

Second, maintain and germinate correctly

After planting, it will enter the critical germination stage. If you want elm to sprout smoothly on time, you must first wrap the old pile in a big plastic bag. In order to have a little ventilation, holes can be made in large plastic bags. After wrapping, you only need to see astigmatism and weak light, so you must avoid exposure to the sun to avoid excessive evaporation affecting germination.

When piling, if the soil is dry, you can pour a little carbendazim solution, which can not only keep the water content, but also prevent the root system from rotting.

In the meantime, if the old elm stump has sprouted, don't feel lucky, because at this time, it may have sprouted by the original accumulated nutrients. At this time, there is no need to withdraw the bag in a hurry, but it is still necessary to shade the nursing, but you can make the eyes of the plastic bag bigger and exercise the buds.

If you want elm to sprout where you want, you can apply gibberellin to stimulate new buds.

Third, summary.

Don't be impatient to plant bare old piles. Sometimes it won't germinate for a long time, but as long as the bark is green, it may germinate. I suggest you wait.

Buds have completely sprouted, branches have been semi-lignified, and bags can be completely removed. You can consider pots in autumn. As for the shape of the flat strip, let's do it next year!
