April
In The Flower Garden This April
April is a fantastic month for flower gardening — everything’s waking up, and what you do now really sets the tone for the whole season. Here are the most useful, practical tips to focus on:
🌱 1. Get Planting (Hardy Flowers First)
April is perfect for sowing hardy annuals directly outdoors, such as:
- Nigella
- Calendula
- Cornflowers
- Larkspur
These cope well with cooler temperatures and will give you early summer colour.
You can also plant:
- Summer-flowering bulbs (like lilies and gladioli)
- Bare-root or potted perennials
🌸 2. Make the Most of Spring Bloomers
Your spring stars like daffodils and tulips will be shining now.
- Deadhead faded blooms to keep things tidy
- Leave the foliage—it feeds next year’s flowers
- Feed with a general-purpose fertiliser to strengthen bulbs for next year
✂️ 3. Prune Carefully
Now’s the time to:
- Cut back penstemons and lavender lightly (don’t go too hard)
- Prune roses if you haven’t already—early April is still okay
- Trim winter-flowering shrubs after they finish blooming
🌿 4. Weed Early, Weed Often
Weeds start racing ahead in April.
- Hoe them off on dry days
- Mulch beds (compost or bark) to suppress future weeds and retain moisture
🌼 5. Feed Your Soil
Healthy soil = better flowers.
- Add compost or well-rotted manure to beds
- Use a balanced fertiliser for borders
- Top-dress containers with fresh compost
🌦️ 6. Watch the Weather (Frost Still Happens!)
Even in April, late frosts are common.
- Protect tender plants with fleece overnight
- Delay planting out half-hardy plants (like cosmos or zinnias) until May
- Harden off seedlings gradually before moving them outside
🪴 7. Start Seeds Indoors or in a Greenhouse
For a head start, sow tender flowers indoors:
- Cosmos
- Zinnias
- Marigolds
A sunny windowsill or greenhouse works perfectly.
🐌 8. Keep an Eye on Pests
As temperatures rise, so do pests.
- Watch for slugs and snails on young shoots
- Check for aphids on new growth
- Encourage natural predators like ladybirds
🌷 9. Divide Perennials
If your clumps are overcrowded:
- Lift and divide plants like hostas or daylilies
- Replant to improve vigour and spread your plants for free
🌞 10. Plan for Continuous Colour
Think ahead now:
- Mix early, mid, and late-season bloomers
- Combine bulbs, perennials, and annuals for a long display
- Fill gaps with fast-growing annuals
This Month's Key Tips
- Keep weeds at bay
- Tie in climbing plants for extra support
- Plant out new strawberry beds
- Sow hardy annual seeds directly into the ground
