There are a lot of plants for beginners, too. For example, perennial flowers will return year after year and can be a good low-maintenance option. If you like to have a one-and-done experience, consider some annuals so you can change the look of your yard each year when you replace them.
Disinfect any tools that touch plants in order to prevent the spread of bacteria, fungi, and soil pathogens. Submerge all you lawn tools – lawnmower blades, shovels, trowels, rakes, pruners, etc. – for 30 minutes in a solution of 10% bleach and 90% water.
