The easiest way to enhance your gardening capabilities is to get an electric cultivator.
For jobs such as aerating, weeding and cultivating between rows, nothing will help you get the job done faster than an electric cultivator.
What once took hours with a shovel, can now be accomplished in a matter of minutes.
Some cultivators are capable of utilizing many attachments to turn them into more multi-purpose tools.
You're already going to be aerating and weeding your garden, but if you want to edge too, then get an attachment-adaptable cultivator.
