2. Sowing time of snapdragon seeds
The snapdragon likes to grow in a warm and sunny environment. Not very heat-resistant, and the survival rate in high temperature weather is very low. Therefore, seeds are usually sown in spring and autumn. The climatic environment in these two seasons is suitable, which is conducive to seed germination and later growth. The requirement of snapdragon on soil is not very high, but it is not suitable for growing in too humid environment, otherwise it is easy to rot roots, so we should choose loose, fertile and well-drained soil for planting.
