Growing guide

Step-by-step instructions for growing Rosemary

  1. 01

    Take Cuttings

    21 Apr to 21 Jul

    Take non-flowering shoots and trim them just below a leaf joint. Insert them into free-draining compost around 21st April - 21st July, and keep them just moist, not wet.

  2. 02

    Pot On Rooted Cuttings

    26 Jun to 17 Jul

    Once roots fill the pot, move each cutting into its own container from 26th June. Use a gritty mix and handle the stems gently so the young roots are not damaged.

  3. 03

    Harden Off

    20 Aug to 4 Sept

    Set young plants outside for short periods from 20th August, 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

    4 Sept to 4 Oct

    Plant into well-drained soil or a larger pot from 4th September. Water in thoroughly at once, then leave the compost to dry slightly before watering again.

  5. 05

    Pinch and Water Sparingly

    19 Sept to 19 Sept

    Pinch out the soft tips from 19th September 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

    28 Sept to 19 Oct

    Pick sprigs regularly from 28th September 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.
