What are the planting methods and precautions for Veronica didyma

Veronica didyma, as a plant with a very peculiar name, has effects and functions such as tonifying the kidney and detoxifying, and as people's understanding of Veronica didyma continues to increase, more and more people are enjoying the benefits of Veronica didyma, so the number of people growing Veronica didyma is also constantly increasing, and as a result, the demand for Veronica didyma cultivation techniques is naturally rising as well.

How to grow Veronica didyma

Veronica didyma likes light; it is a long-day plant, and light should be kept at a relatively high level. Supplementary lighting is needed in winter and early spring. Temperature should generally be kept at a relatively good level, and in winter take care to cover the plants for overwintering. Medium fertility is sufficient.

When choosing soil for Veronica didyma, generally choose soil with good drainage.

Planting methods and precautions for Veronica didyma

1. Pot and soil selection

For potted Veronica didyma, choose a flower pot of moderate size; basically a pot with a diameter of about 18 cm is sufficient, and no repotting is needed during the growing season. For the soil, you can choose fertile, well-drained sandy soil; a mixed soil is better and can allow air circulation. Put soil in the pot, and at the same time add some fertilizer as a base fertilizer.

2. Light and temperature

Veronica didyma likes light and can tolerate partial shade. During the growing period of Veronica didyma, a relatively high level of light should be maintained. Long-day conditions help the plant bloom; if the sunshine duration is shorter, the plant is prone to leggy growth. In winter and early spring, when the sunshine duration is shorter, artificial supplementary lighting is needed. As for temperature, the suitable temperature for the growth of Veronica didyma is between 15℃——35℃. Winter temperatures are low, so attention should be paid to keeping warm.

3. Watering and fertilizing

Veronica didyma does not have high requirements for water and fertilizer, but it likes fertility, and in winter it is averse to waterlogging. During the seedling recovery stage, growing stage and flowering stage of Veronica didyma, the soil needs to be kept moist. If there is a water shortage due to drought or other reasons, then timely watering is needed. A medium amount of fertilizer is sufficient. During the vigorous growth period, timely topdressing is needed to ensure the balance of various growth elements. During the flowering period, attention should be paid to applying more phosphorus and potassium fertilizer. Entering 9 down jacket allows you to reduce fertilizing.

4. Pests and diseases

Veronica didyma has relatively few pests and diseases, but in autumn, powdery mildew sometimes occurs, and timely prevention and control are needed.

5. Pruning

One reason to prune Veronica didyma is for appearance; after Veronica didyma blooms, the flowers will not fall off on their own, so pruning is needed. Secondly, pruning can control the flowering period. By pruning according to the growing conditions of Veronica didyma, the flowering period can be controlled within the range you want.

How to grow Veronica didyma from seeds

1. Prepare the seedling-raising environment

First, we can prepare a wooden box in a greenhouse with a moderate depth, then put in the soil needed for sowing. Remember to make the soil as loose as possible, and it should also have a certain fertility. It is best to prepare it with garden soil, leaf mold, etc. After that, sterilize them at high temperature, then place them in a cool place to dry.

2. Sowing

We scatter the prepared seeds into the wooden box. Because seed germination needs light, after sowing we only need to cover them with a thin layer of vermiculite; do not cover with a very thick substrate, otherwise it will make it difficult for them to break through the soil. In addition, make sure the substrate is appropriately moist, do not expose it to strong light, provide appropriate shading, and then control the temperature between 28 and 24 degrees. Generally, in one week to half a month, they will begin to sprout.

3. Care after sowing

1. Transplanting

When the seedlings grow to a certain height, we need to transplant them separately. When transplanting, pay attention to the distance between plants so as to promote root growth and plant development. After transplanting, pay attention to care; do not just leave them unattended.

2. Temperature

After the seedlings emerge, we need to ensure the temperature is suitable. Usually the daytime temperature is best between 12 and 18, and the nighttime temperature is best between 10 and 13 degrees. If you are cultivating outdoors, in winter you also need to cover the plants in time to prevent frost damage.

3. Moisture

Usually pay attention to timely watering, and do not let the flower soil dry out.

What is Veronica didyma

Veronica didyma (Latin name: Veronica didyma Tenore): an annual to biennial herbaceous plant, with short pubescence. It has three colors: blue, white and pink. The stem branches from the base, and the lower part creeps along the ground. Triangular-round or nearly round leaves are opposite on the lower part of the stem and alternate on the upper part, with rounded teeth on the edges. In early spring it produces small purplish-red flowers, solitary in the leaf axils. Fruit period is March to May.

It likes light, tolerates partial shade, and is averse to winter waterlogging. It does not have high requirements for water and fertilizer conditions, but likes fertile, moist, deep soil. It begins to grow in early April, the flowering period is June to September, it withers at the end of October, and the suitable growth temperature is 15 to 25℃. Functions and indications: cooling blood and stopping bleeding, regulating qi and relieving pain. Used for hematemesis, hernia, orchitis, and leukorrhea. The main components are: ferulic acid, 3-O-acetyloleanolic acid, 3,4-dimethylcinnamic acid, daucosterol, β-sitosterol, mannitol, etc. It grows wild commonly throughout China; it is distributed in temperate and subtropical regions of Europe and Asia.

Veronica didyma is actually among very common plants. As stated in the article, Veronica didyma grows wild commonly in all regions of China, but it is very unrealistic to obtain a very large yield from wild Veronica didyma, so concentrated planting and production are very necessary.
