April indicates that Spring has obviously arrived, evidenced by daffodils and flowering trees being in full bloom. Everything else is starting to grow, including the lawn, which means that seeding of bare areas can now be undertaken. If you are confident that frosts are over, then you can start sowing outdoors, but don’t forget to monitor the local weather forecast just in case a rogue late frost puts in an appearance.
- Keep on top of general garden maintenance, i.e. weeding.
- If a late frost is forecast, ensure that vulnerable plants and blossoms are protected.
- To maintain structure, tie in climbing and rambling roses.
- Sow seeds for hardy annuals and herbs.
- Fertilise hungry plants such as shrubs and roses.
- Sow grass seed to create new lawns or repair bare patches.
- Divide bamboos and water lilies to ensure that the plants do not become too congested.
