Using dull or rusty tools requires so much more effort from the gardener than properly maintained tools do. So, creating an annual schedule to care for your tools is time well invested.
Here are some Care Tips to get you started:
Shovels, pruners, hoes and similar tools need periodic sharpening and oiling of the blades.
Tools with wooden handles can deteriorate due to exposure to weather and improper use or storage.
