In The Flower Garden This June

Here are the top flower garden tips for June, when your garden is bursting into full summer colour and needs regular care to stay at its best: 

 🌸 1. Deadhead Regularly 

• Remove spent blooms from roses, lupins, delphiniums, and annuals to encourage more flowers and keep borders tidy. 

• Cut back early-flowering perennials like geraniums and alchemilla to promote a second flush. 

🌿 2. Water Wisely 

• Water deeply and less frequently to encourage strong roots. 

• Focus on newly planted flowers and containers, especially during dry spells. 

• Water in the early morning or evening to reduce evaporation. 

🌺 3. Feed for More Flowers 

• Use a high-potash liquid feed (like tomato fertiliser) every 1–2 weeks on:

• Containers and hanging baskets 

• Dahlias, roses, and bedding plants 

• Mulch with compost or manure to boost soil fertility and retain moisture. 

🌞 4. Support Tall Perennials 

• Stake or tie in tall flowers like delphiniums, foxgloves, and peonies before wind or rain causes them to flop. 

🌼 5. Fill Gaps for Summer Colour 

• Plant summer bedding, dahlias, and annuals (cosmos, zinnias, marigolds) in any bare spots. 

• Add potted perennials for instant impact if needed. 

🌱 6. Sow Biennials for Next Year 

• Sow foxgloves, wallflowers, honesty, and sweet William in trays or seed beds for flowering next spring. 

🐛 7. Watch for Pests and Diseases 

     Check for: 

• Aphids on new growth 

• Black spot and mildew on roses 

• Slugs and snails on young plants 

• Use organic treatments or natural deterrents where possible. 

🌳 8. Prune Spring-Flowering Shrubs 

• Prune lilac, forsythia, and weigela after flowering to maintain shape and encourage new growth for next year’s blooms. 

🐝 9. Plant for Pollinators 

• Include nectar-rich flowers like lavender, scabious, salvia, and echinacea.

• Let some herbs like thyme and oregano flower for bees. 

✂️ 10. Enjoy and Cut Flowers 

• Pick sweet peas, roses, and cosmos regularly to encourage more blooms and enjoy fresh arrangements indoors.
