Starting Chater's Double Mix from seed
How to grow Chater's Double Mix Hollyhock
Botanical identity: Alcea rosea. Life cycle: Biennial.
Sow 1/4 in and use a seed-zone temperature near 65–80 °F. Expected emergence: 10-21 Days. Use clean seed-starting conditions, the listed depth and temperature, and steady moisture without saturation.
Plant during Spring/Fall. Space plants 18 in apart with 30 in between rows or planting bands.
Provide Full sun, moderate water, and loamy near pH 6.5–7.0. Support: Stake.
Garden performance and care
For a longer display of Chater's Double Mix, remove spent blooms unless seed is being saved. Give the plant its listed spacing, cut flowers with clean tools, and leave selected heads to mature fully for seed. Expected emergence is 10-21 Days; the listed maturity or bloom timing is 365+ Days.
Harvest, bloom, and uses
Chater's Double Mix is suited to borders, cut flowers, containers or meadow-style planting, pollinator value, and seed saving. Its mixed flowers and 73–96 in stature help determine whether it belongs in a border, cutting row, container, meadow edge, or restoration-style planting. Grown for ornamental or habitat use rather than as a food crop.
Saving seed
Choose several healthy, true-to-type plants rather than saving from one unusually early or large individual. Allow seed structures to mature fully beyond the ornamental stage, harvest in dry weather, and finish drying under cover. Clean out chaff and damaged seed, keep the lot labeled through every step, record isolation and selection, and store fully dry seed in a cool, dark, low-humidity place. Confirm the species pollination system before promising varietal purity.
Common problems
Common concerns: damping-off from saturated media; poor emergence from wrong temperature or depth; leggy seedlings from weak light; crowding and weak airflow; lodging in wind or rain; feeding damage from slugs, caterpillars, beetles, or mammals; foliar disease under prolonged leaf wetness; hollyhock rust. Management: use clean media, the sowing depth and temperature, strong light, appropriate thinning, and morning irrigation at soil level. Match support to plant height before wind becomes a problem. Inspect regularly and use the least disruptive control appropriate to the pest, plant, and pollinator setting. Remove diseased debris and rotate annual flower beds where recurring disease is severe.
