WaterThe common Hollyhock (Alcea rosea Chater's Double Group white-flowered) requires regular watering, especially when the weather is dry. In general, water these biennials to a depth of about 2 inches once a week, providing about 1.5 gallons of water per plant during this watering session. During the hotter summer months, the frequency may need to increase to twice a week to maintain moist but not waterlogged soil. It's vital not to overwater, as Hollyhocks are susceptible to root rot. Always water at the base of the plant to avoid wetting the foliage, which can contribute to rust and other fungal diseases.
LightHollyhocks thrive in full sunlight, so Alcea rosea Chater's Double Group white-flowered should be placed in a spot where it can receive at least 6 hours of direct sunlight daily. An ideal location would be an open area away from larger structures or trees that might create shade. These plants do well in bright and sunny gardens and can tolerate some light shade, but they will produce the strongest growth and best flowers in full sun.
TemperatureHollyhocks prefer a temperate climate with temperatures ranging between 60°F and 90°F. The Alcea rosea Chater's Double Group white-flowered can tolerate a minimum temperature of 40°F, but growth will be stunted if temperatures consistently fall below this threshold. They can survive in high temperatures up to approximately 100°F, but prolonged heat can stress the plant. The ideal temperature range for optimal growth is between 70°F and 85°F.
PruningPrune Hollyhocks to promote healthy growth, improve air circulation, and encourage more blooms. Alcea rosea Chater's Double Group white-flowered should be deadheaded regularly by removing spent flowers. Additionally, in late winter or early spring, prune out any dead or damaged stalks to make way for new growth. Pruning after blooming can also help to prevent rust disease, a common issue with Hollyhocks. The best time for major pruning is after the plant finishes flowering in the summer or fall.
CleaningAs needed
SoilHollyhocks prefer well-draining, fertile soil with a neutral to slightly alkaline pH, around 6.0 to 8.0. A mix of loamy soil, compost, and a bit of sand for improved drainage is ideal.
RepottingHollyhocks are biennial or short-lived perennials and do not typically require repotting; they are usually sown directly outdoors.
Humidity & MistingHollyhocks tolerate a wide range of humidity levels but prefer drier conditions to prevent rust disease.

Life cycleAlcea rosea, commonly known as Hollyhock, begins its life cycle when its seeds germinate in the spring after the last frost has passed. The seedlings grow into rosettes of leaves at the soil surface, where they develop a deep taproot and prepare for future growth. In the first year, Hollyhocks focus on vegetative growth, producing large, lobed leaves. The second year, they send up tall flower stalks, which can reach up to 6 to 8 feet tall, and the white double flowers of the Chater's Double Group bloom, attracting pollinators. After flowering, the plant sets seeds, which disperse to start new plants. Hollyhocks are short-lived perennials and biennials, and after seeding, they often die, completing their life cycle, though some may survive to bloom another season.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating Hollyhock (Alcea rosea Chater's Double Group white-flowered) is through seed sowing. Seeds can be started indoors about 6-8 weeks before the last expected frost. Plant seeds at a shallow depth of 1/4 inch (about 0.64 cm) into a well-draining seed starting mix. Keep the soil consistently moist but not waterlogged, and provide ample light. Seeds typically germinate within 2-3 weeks. Seedlings can be transplanted outdoors once the risk of frost has passed and they have developed several true leaves. Hollyhocks are biennials or short-lived perennials, so seeds planted in year one will typically flower in the following year.
