How to grow dahlia seeds? A detailed guide to the planting method

Dahlia is also called dahlia, tree dahlia, Japanese chrysanthemum, dahlia pinnata, sweet potato flower, etc. It originated in Mexico, and it is one of the species with the most flower varieties in the world, with a wide range of flower colors and flower shapes. So, how do you grow dahlias? Below is an introduction to the method of growing dahlia seeds.

1. Soil: Dahlia is suitable for planting in loose, fertile, well-drained sandy soil. You can directly buy ready-made potting soil, or mix the materials yourself, and then sow the seeds directly into the soil.

2. Environment: Dahlia likes semi-shaded, cool places. After planting, it should be placed in a semi-shaded, cool place; it can grow normally at temperatures of 5-35 degrees, and when the temperature is above or below this range, appropriate cooling or warming measures should be taken.

3. Fertilizer and water: The root system of dahlia is relatively delicate, so when watering and fertilizing, do not pour directly onto the root system, and it is best to dilute the fertilizer. The amount of watering should be determined according to the dryness and moisture of the potting soil. Generally, water more in summer and less in winter.

4. Pests and diseases: During the growth of dahlia, it is prone to attack by root nodule disease, brown spot disease, powdery mildew, fruit borers, aphids, and other pests and diseases, so preventive work should be done in advance. After diseases occur, spray pesticides promptly, and branches and leaves with more serious conditions can be directly removed.
