Common Pests and Diseases affecting Plants

At Tanby Garden Centre we stock a range of products for controlling pests and diseases, nevertheless, we are also keen to encourage you to take a cautious and sensible approach to their usage and step lightly on this earth.

Chemical intervention should always be a last resort, remembering that these products kill beneficial pests as well as the harmful ones.  Thankfully today there are some good organic products that can be used when intervention is necessary. A stressed plant is much more susceptible to pests and diseases than a healthy plant. Start with checking some of the basics such as:

  • Light levels - requires more or less sunlight

  • Watering - soil is too wet or too dry

  • Drainage - good drainage is required

  • Nutrition - requires fertilising, plants need food too.
