I really think there should be some kind of app that allows you to input each plant (and position etc if known)
And it should have a Callander that tells you what to do each week in really simple terms. Maybe suggestions of other things you could do to keep your garden healthy.
An app for people (like me) who are vaguely interested in gardening but has lots of other crap going on so that gardening efforts tend to happen in massive spurts every 12 weeks
Is there something like this already?
