Care through the season
Watch soil moisture during establishment and adjust watering to the weather rather than to a fixed schedule. Remove damaged growth and use species-appropriate pruning, staking or division only when it supports healthy long-term development.
Harvest, use or garden role
Plan the plant for structure, flowering period and long-term space. Cultivar, exposure and local winter conditions can make a noticeable difference to height, flowering and hardiness, especially in containers or exposed sites.
Calendar dates are orientation only. Local temperature, rainfall, soil condition and cultivar should always take priority over a fixed month.
