Gardening in Portsmouth
Use this forecast to time jobs in the garden. Sow and plant out tender crops only once frost risk has passed, water in the cool of the morning or evening, and take shelter from strong winds into account. See our frost dates by region, month-by-month calendar and growing guides to plan the season.
