If it is ramet and cutting should be carried out in spring, but the general production is mainly sowing, so the following mainly introduces the methods of sowing hollyhock and the main points of watering and fertilization.

1. Hollyhock can be used for sowing after the seeds are ripe and picked in August and September of that year, and can blossom the following year. If the bought seeds are sown in spring, they will blossom the following year, and they will almost emerge a week or so after the seeds are planted. In the south, if you sow seeds in autumn, you should pay attention to adding mulch to the seedlings to keep out the cold after winter.

two。 Hollyhocks like cool climate and light, are not resistant to heat and frost, and slightly resistant to shade; they are most suitable for planting in deep, fertile, well-drained soil. When sowing, you can directly sow seedlings in the open field and then transplant, or direct seeding without transplanting; transplanting should be properly combined with rainy days, which can help the seedlings.

In this way, to ensure the moisture in the flowering period, not only the plant growth is better, but also the flowering period may be prolonged.

(3) plants begin to go dormant in autumn and winter, and hollyhock is no exception. At this time to reduce the amount of water and watering times, into the cold winter to stop watering to keep warm.

In addition, we should remind you that summer watering should be carried out in the morning and evening, and if the soil is relatively dry, it should be watered thoroughly.

4. The nutrients needed for plant growth are not only from the soil and photosynthesis, but also from the fertilizers we use:
