3.Examine plants carefully before buying
The best way to stop the diseases in your garden is to avoid introducing it in the first place. Getting a disease with a new plant is not the kind of bonus that any of us wants.
One of the toughest things to learn is what a healthy plant should look like, making it hard to know if the one you want is sick.
It is an excellent idea to collect a few books, magazines, and catalogs that show what a healthy specimen looks like.
stop taking home a plant with dead spots, rotted stems, or insects. These problems can easily stretch to your plants and are sometimes hard to get rid of once settled.
