Plant fertilisers will make available essential nutrients to plants. Weedkillers will control unwanted plants. Pesticides will control aphids and other common garden pests.

Healthy plants are more resistant to pests and diseases. So alway try to use fertilisers and weedkillers sparingly. Additionally look for natural alternatives first. Careful planting and good gardening will resolve many problems before they appear.

 Plant new shrubs and perennials in the spring. Ensure the ground is well prepared and use bark mulch to suppress weeds. Feed plants with granular plant food when planting. Additionally use liquid food on established plants.
