How long does it take to grow Davallia from planting to harvest?

Davallia is a fern and a traditional Chinese medicinal herb. Its roots have the effect of strengthening bones and tonifying the kidney. It is distributed in Shandong, Jiangsu, Taiwan, China and Liaoning in our country. In the past, it all grew wild in mountain valleys, woodlands and rock crevices. Now it can also be planted artificially. So how long until it can be harvested after artificial cultivation, and how long is the planting time. Friends who want to know can continue reading.

1. Planting and harvesting

Ferns grow very quickly. Generally, after sowing spores for 2 months, the sporophyte can grow out, but because the main harvest is the rhizome, the growth of the roots may generally be slower. Usually around May the spores mature and can be sown, in July the sporophyte grows out, and in August the root system is not yet complete. It can be harvested in April of the following year, about one year in total.

2. Propagation methods

Generally it is spore propagation, which is very fast. Under natural conditions, very few spores germinate, so spores can be collected artificially, air-dried, made into a sporangium suspension, sprayed onto sterilized cinder soil, and exposed to light. Gradually gametophytes will form, and after fertilization they become sporophytes that are then transplanted onto trees for growing. For division propagation, use rhizomes cut into sections, keep the bud points and spore-bearing leaves, and place them in rock crevices. Spray water frequently to keep them moist, and they will grow.

3. Moisture management

Cultivating Davallia has very strict humidity requirements. After seedlings grow, they must be watered or sprayed every day. If any wither, take them down and soak them in water. After the leaves recover, plant them back. If they do not recover, cut off the withered leaves to encourage new leaves. If they first turn yellow and then wither, do not water; there may be water accumulation and root rot, so take them out, trim the roots and replant. It is best to water in the morning, not at night, and keep good ventilation.

4. Nutrient management

The planting soil should be loose, fertile and slightly acidic. It can be mixed yourself using humus soil, peat soil and coarse sand, with the most humus soil and less of the others. Fermented compost can also be used. The root system is weak, so fertilization should be light and frequent. Use dissolved fertilizer and nitrogen fertilizer, but do not overdo it, or they will grow leggy and compete with the roots for nutrients. Phosphorus fertilizer must not be lacking, as it promotes root growth; spray potassium dihydrogen phosphate. Apply potassium fertilizer to avoid yellowing.

Davallia can generally be harvested after about one year of planting, but if you want the roots to be larger, you can also delay the harvest. It can be dug up throughout the year. The spore propagation method of planting should be noted, as it is different from ordinary plants. The most important things in cultivation management are moisture retention and fertilization.
