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
