August
In The Flower Garden This August
August is a beautiful and busy time in the flower garden. Here are some top tips to keep your garden looking its best this month:
🌸 1. Deadhead Regularly
- Why: Encourages more flowers and keeps the garden tidy.
- What to deadhead: Roses, dahlias, cosmos, rudbeckias, geraniums, delphiniums.
💧 2. Water Wisely
- Early morning or evening is best.
- Use a soaker hose or water directly at the base of plants to reduce evaporation and avoid mildew.
- Focus on containers and newly planted areas which dry out fastest.
🌱 3. Keep Weeding
- Warm weather = fast weed growth.
- Regular weeding prevents them competing with your flowers for water and nutrients.
✂️ 4. Prune Summer-Flowering Shrubs
- Prune lavender once it’s finished blooming—cut back to the green growth but avoid old wood.
- Trim wisteria (summer prune): cut whippy side shoots back to 5 or 6 buds.
🍂 5. Prepare for Autumn
- Start planting spring-flowering bulbs like crocuses, daffodils, and hyacinths.
- Consider buying bulbs now while stocks are good.
🌻 6. Feed and Mulch
- Feed containers weekly with liquid feed (tomato feed works well for flowers too).
- Top up mulch to conserve moisture and suppress weeds.
🐞 7. Look After Wildlife
- Leave some seed heads (e.g. echinacea, sunflowers) for birds.
- Keep bird baths topped up and clean.
🌾 8. Divide Irises
- August is ideal for dividing bearded irises after flowering.
- Replant rhizomes so they sit just above the soil to bake in the sun.
🌿 9. Take Cuttings
- Take softwood or semi-ripe cuttings from salvias, pelargoniums, fuchsias, and penstemons to propagate for next year.
🌤️ 10. Enjoy the Garden!
- Sit and enjoy your hard work—late summer evenings are some of the best in the garden.
