What to do in the garden in April

Sow sweet peas

Transplant the sweet peas sown in autumn into their final positions. Place several sweet peas seedlings at the base of supports and sow extra seeds to extend the growing season.

When plants are 10cm tall, pinch out the tips to encourage bushy growth. Most varieties have tendrils that will ‘self-cling’ to supports, but some sweet peas will need tying in.

Top Tip

Sweet peas love a rich, moist soil so dig a couple of buckets of compost into the planting area beforehand to enrich the soil and hold moisture during dry weather.

Sow small batches of rocket and other easy salad leaves

Sow direct outdoors by scattering the seeds thinly along a drill, 0.5–1cm (¼–½in) deep. If sowing several rows, space them 15cm (6in) apart. For a continuous supply of leaves, sow small batches every two to three weeks.

Top Tip

If your soil is rich enough in compost then you probably won't need to feed your rocket or salad leaves at all. But if you're growing them continuously within a growing season, then you could consider applying small amounts of liquid fertiliser.

Start feeding houseplants

Now is a good time to start feeding your houseplants. In general, most houseplants should be fed every second watering during the growing season, which is probably every 10 to 14 days.

Top Tip

Continuing through to autumn feeding house plants once a week with Tend, houseplant feed.

Sow tender vegetables

  • Sweetcorn needs somewhere frost free at night to germinate
  • Runner and French beans need good light
  • Courgettes, marrows and squashes all need a bit of warmth to germinate.

To start the seeds off you can use plastic cell trays, plastic or terracotta plant or fibre pots.

Top Tip

To avoid any root disturbance when planting out, sow seeds individually in small pots or cell trays of multi-purpose compost.

Remove moss and weeds in turf

The lawn is now actively growing and how you look after it depends on what you want to achieve. To encourage wildflowers for pollinating insects, it’s time to stop mowing and enjoy the visits to the flowers that appear. For a short cut lawn, now is the time to sprinkle grass seed.

Top Tip

Boost growth by adding Green lawn feed.
