Gardening in June: 15 Essential Tips for a Thriving Summer Garden 🌸
June is one of the most rewarding months in the gardening calendar. With longer days, warmer temperatures, and gardens in full bloom, gardening in June is all about maintaining growth, encouraging flowering, and enjoying the results of your hard work.
Whether you’re tending borders, growing your own vegetables, or keeping your lawn in top shape, these expert gardening tips will help you keep your garden looking its best all summer long.
🌼 Brighten Your Garden with Summer Colour
1. Plant Up Pots & Hanging Baskets
June is the perfect time to fill containers with vibrant summer bedding plants.
Top choices include:
- Trailing geraniums, petunias, and lobelia for sunny spots
- Busy lizzies and begonias for shaded areas
👉 Expert Tip: Feed every two weeks with a high potash fertiliser to promote continuous flowering.
2. Plant Out Tender Crops
Harden off and plant out:
- Runner beans
- French beans
- Courgettes
- Squash
- Tomatoes
This ensures strong, healthy plants ready for summer growth.
3. Sow Little and Often
Keep your harvest going by sowing:
- Salad leaves
- Carrots
- Beetroot
👉 Pro Tip: Successional sowing every 2–3 weeks ensures a steady supply.
4. Check Your Potatoes
First early potatoes may be ready now. Gently lift one plant to check size before harvesting the rest.
5. Feed Fruiting Crops
Tomatoes and container-grown vegetables benefit from fortnightly feeding with a high potash fertiliser.
This encourages:
- Strong fruit development
- Better yields
- Healthier plants
6. Harvest Onions & Garlic
Once leaves turn yellow and begin to flop, your onions and garlic are ready to harvest.
👉 Allow them to dry in a warm, airy place before storing.
7. Protect Your Strawberries
As fruits ripen, cover plants with netting to keep birds from stealing your crop.
🌸Keep Flowers Blooming All Summer
8. Deadhead & Pick Regularly
- Deadhead repeat-flowering plants like roses, peonies and Alstroemeria (Peruvian lily)
- Pick sweet peas frequently
- Cut back hardy Geraniums
This encourages plants to keep producing flowers.
🌿Lawn Care & Wildlife-Friendly Mowing
9. Mow Smart in Summer
- Mow regularly in normal conditions
- During dry spells, mow less often and raise blade height
👉 Eco Tip: Leave a section uncut to support pollinators and wildlife.
🌱Weed Control Made Easy
10. Stay on Top of Weeds
Weeds grow rapidly in June.
Control them by:
- Hoeing and hand weeding on dry days
- Leaving cut weeds on the surface to dry out
This is especially effective for annual weeds.
✂️ Pruning & Garden Maintenance
11. Prune Wisteria
Cut back long, whippy shoots to around 20cm to keep plants tidy and encourage flowering.
12. Trim Evergreen Hedges
Maintain neat hedges, but always check for nesting birds before trimming.
13. Prune Summer-Flowering Shrubs
After flowering, prune:
- Philadelphus (mock orange)
- Weigela
- Forsythia
Cut back flowered stems and remove older wood to encourage fresh growth.
14. Water Efficiently
Water early morning or evening to reduce evaporation.
Improve efficiency by:
- Installing water butts
- Mulching soil to retain moisture
👉 Expert Tip: Focus watering at the base of plants to avoid waste and reduce disease risk.
🌟 15. Extra Expert Tips for Gardening in June
To go beyond the basics:
- Feed hanging baskets weekly during peak flowering
- Stake tall plants early to prevent wind damage
- Check for pests like aphids and treat quickly
- Harvest crops regularly to encourage continued production
- Group containers together to reduce water loss
