April is a brilliant month for us gardeners... tulips and daffodils are flourishing and there is new growth each and every day. However, it is also a month which can have some devastation if not careful... FROST! Please, please, please do not plant out any tender plants until after the last risk of frost has passed- this is usually in May.
But whilst we wait for the risk of frosts to pass we can certainly keep busy in the garden!
- Sow flower seeds (see 'Flower seeds to sow in April' blog post)
- Now the weather is warmer we can direct sow some flower seeds. Do this on a nice warm day.
- Protect new shoots of perennials such as Hostas, Delphiniums or Lupins from slugs and snails. (I recommend Wool pellets)
- Continue deadheading spring bulbs and bedding plants so they dont waste energy setting seed. By deadheading the bulbs, the energy will go back into the bulbs for n extra special display next year. If you have bulbs planted in grass, don't be tempted to mow the grass until the bulbs die back
-Plant out Sweet peas into their final position. Ensure you prepare the ground well and ensure you 'harden off' your Sweet peas for 10 days before you plant out.
- Prune hydrangeas, cutting back the old stems back to a healthy bud lower down
- Now is a good time to divide and move perennials before the hot weather. Dig a large area around the roots and break into smaller plants Ensure you give them a good water once you've planted them.
- Check roses for aphids and rub them off before any infestations
- If you have a garden pond, now is a good time to add aquatic plants such as water lilies
Don't forget to take time to enjoy your garden!
