Growing guide

Step-by-step instructions for growing Rosemary

  1. 01

    Take Cuttings

    17 Jan to 18 Apr

    Take non-flowering shoots and trim them just below a leaf joint. Insert them into free-draining compost around 17th January - 18th April, and keep them just moist, not wet.

  2. 02

    Pot On Rooted Cuttings

    24 Mar to 14 Apr

    Once roots fill the pot, move each cutting into its own container from 24th March. Use a gritty mix and handle the stems gently so the young roots are not damaged.

  3. 03

    Harden Off

    18 May to 2 Jun

    Set young plants outside for short periods from 18th May, then leave them out longer over about 10 days. Keep them sheltered from cold wind and bring them in if a late frost is forecast.

  4. 04

    Plant Out

    2 Jun to 2 Jul

    Plant into well-drained soil or a larger pot from 2nd June. Water in thoroughly at once, then leave the compost to dry slightly before watering again.

  5. 05

    Pinch and Water Sparingly

    17 Jun to 17 Jun

    Pinch out the soft tips from 17th June to keep plants bushy and stop them becoming leggy. Water only when the compost has dried a little, and avoid feeding heavily because that makes soft growth.

  6. 06

    Harvest Shoots

    17 Jul to 10 Dec

    Pick sprigs regularly from 17th July once plants are well established. Take small amounts at a time, and avoid cutting back into old bare wood as it may not reshoot well.

Plants to avoid

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
