Hollyhock potted planting and care methods: timely root pruning is key
Hollyhock (Alcea rosea) originated in the Sichuan region of China, hence the name "Shukui" (Sichuan mallow). Its flowers are large and brilliant, and it can grow as tall as one zhang, so it is also called "Yizhanghong" (one-zhang red). Its flowering period is from June to August. Today let's take a look at how to grow hollyhock in pots~

Growth habits
Hollyhock likes a sunny environment and tolerates partial shade. The suitable growth temperature for hollyhock is 25-30°C, and the most suitable temperature for flowering is between 25-28°C. A monthly average temperature below 15°C will affect flowering, and a nighttime temperature below 13°C will cause poor plant growth.

Pot and soil selection
Hollyhock is not very fussy about soil. For potted hollyhock, loose, fertile, well-draining sandy soil rich in organic matter is most suitable for growth. Before planting hollyhock, deeply turn the soil and add base fertilizer to the soil.

Watering & fertilizing
Pay attention to watering normally and keep the soil moist, but do not overwater and cause waterlogging, as hollyhock is afraid of waterlogging. Proper watering during the vigorous growth period of hollyhock can extend the flowering period and increase the number of flowers. During the growth period, apply liquid fertilizer mainly based on nitrogen fertilizer and potassium fertilizer once or twice. After the flower buds form, apply liquid fertilizer mainly based on phosphorus and potassium fertilizer once or twice more.

Everyday care tips for hollyhock
After hollyhock blooms, the aboveground part of the root system should be cut off in time, and new shoots can still sprout. In summer, when the temperature is high and the sunlight is strong, try not to place it in direct sunlight to avoid affecting plant growth. Provide appropriate shade and let it receive diffused light. To grow hollyhock well in pots, and also to dwarf the plant for easier cultivation, the root-cutting method can be used to control height. That is, during the growth period, use a milling cutter to vertically cut the root system at 10 cm to the left and right of the root, and repeat the same cutting at the latter two places after 2-3 weeks. The more times the roots are cut, the more dwarfed the plant becomes, making potted care and management more convenient.
