 The reason that this is so important is that I could buy a plant from abroad. It could look absolutely fine But the problem can be absolutely tiny one that I wouldn't be able to identify with my eyes Some of the pests and diseases can be microscopic So bringing them into my garden here could cause devastation or bringing them into a farm couldn't cause Untill damage to our food systems So before you order and purchase get to know the plant health requirements in your country And if you're in doubt contact your government office for more local information So let's all be mindful when we're buying plants or plant products online Things you can do are checking out the reputation of the supplier We all have a role to play in keeping our gardens and our farms and our food sources safe When we protect plants we protect our food our environment and our lives
