Michael Perry

Michael Perry Advice

"Our 'garden-ready' plant range is a much larger plug plant than usual and, if the weather allows, can be planted directly into their final containers and into beds and borders from the end of May. Please keep an eye on the weather forecast though, and never plant outside if a frost is forecasted. If you have planted and then news of frost comes, then make sure you cover plants with fleece or some old net curtains temporarily."
