A Detailed Guide to the Latest Planting Methods for Viola mandshurica

Viola mandshurica is a perennial herbaceous plant, also known as purple violet, rabbit's ear grass and violet grass. It has the effects of detoxifying, cooling the blood and reducing swelling, and clearing heat and draining dampness, and is a good medicine for treating jaundice, mastitis, red swollen and painful eyes, and venomous snake bites. In addition, its flowers are purple and have extremely high ornamental value, and it is often seen in landscaping gardens, so how should it be planted? Let's take a look together.

1. Site selection

Viola mandshurica prefers a warm and humid environment, and it is best to plant it in sandy loam with sufficient water sources, deep soil layers, loose and fertile soil texture, and good drainage. It is afraid of drought and avoids continuous cropping, and it can be interplanted with tall crops, such as sorghum, corn and similar crops.

2. Propagation

It is mainly propagated by sowing, and the seeds are collected when they are about to mature. The seeds of Viola mandshurica are relatively small, and once the fruit matures the seeds will pop out automatically, so the seeds must be harvested when they are mature and the pods have turned yellow but have not yet split, then dried and prepared for sowing. Its sowing method is extremely simple: after corn and other plants have closed their rows, dig shallow furrows between the rows, evenly scatter the seeds between the rows, then cover with soil and press lightly, and water to keep the soil moist. Seedlings will emerge after about one month.

3. Field management

Viola mandshurica is a shade-loving plant, so after the seedlings emerge it should be watered frequently, the soil should be kept moist at all times, and water depletion should be prevented. In autumn, when the crops mature and are harvested, do not bury the seedlings, so as to avoid poor permeability causing the seedlings to die. Before the winter freeze, apply freeze water and overwintering fertilizer, and it is recommended to cover around the roots with farmyard manure; after the thaw in the following spring, break up and level the farmyard manure. Then, around the Qingming and Guyu periods, apply 15 kg of urea per mu to promote the sprouting of new leaves. After fertilizing, water immediately, which can both reduce the concentration and avoid fertilizer burn to the seedlings, and also allow the fertilizer to be absorbed more quickly. After summer begins, stop watering to avoid the stems and leaves rotting.

4. Pests and diseases

Around the time of Jingzhe, when the seedlings begin to turn green again, the plants will encounter a kind of pest that feeds on the tender buds of violet grass, causing the plants to be unable to grow normally. The damage is extremely great, and in severe cases it eats the growing points clean and the plants die. At this time, Bacillus thuringiensis preparations can be sprayed for control, or bacterial powder can be mixed with fine soil to make poisonous soil and spread on the soil to poison and kill them.
