Mature seedling
Generally mature seedlings, that is, artificially cultivated ash, are generally better to feed. Or it is easier to feed by buying a potted plant with ash for more than 2 years. This bonsai should pay attention to the following three points:
1, big water does not accumulate.
Duijie Fraxinus is a precious root carving and bonsai, which originated in Hubei. The climate in Hubei is hot and humid, so we should keep the potted soil moist all the summer, and don't let the potted soil dry. In other words, it is different from the "watering principle of seeing dry and seeing wet" of other flowers. Watering once in the summer morning or after sunset, be careful not to accumulate water, which will easily lead to poor breathing, unfavorable nutrient absorption and even yellow leaves. This also depends on the specific gravity of soil and the treatment of basin leakage when the basin is released in autumn and winter.
2. Big fertilizer promotes crazy growth
Ash bonsai is a kind of plant that likes to be thick and fat, with abundant nutrition, and some plants can grow to 30-40 cm. This crazy growth is conducive to plastic surgery, shaping, binding, topping and other treatments. Suggestion: Fertilization should be mainly based on nitrogen fertilizer, such as urea, generally once a week, and it is appropriate to spray 0.2% potassium dihydrogen phosphate every10g according to the size and area of the basin soil. At the same time, in order to enhance disease resistance and avoid yellow leaves, it is recommended to spray once every 15 days.
3. Plenty of light
In summer, potted plants can be placed in sunny places, which is more conducive to the crazy growth of plants, with thick branches and red buds.

For mature bonsai, topping can be carried out purposefully in the vigorous period, and twigs should not be cut off.
5. There are no mountain piles or bonsai with serving pots.
Be careful not to apply fertilizer, as long as it is kept moist, it can be maintained normally after being put into the pot or after the growth is fully restored. Special reminder: it will take at least 1.5-2 years for the pile to go downhill.
