I’ve decided (on the spur of the moment, as most of my decisions are made) to try to make my vegetable garden low maintenance for while we are away. By their very nature, vege patches require regular attention, but I thought if I plonked in lots of non-annual herbs and let the strawberries and rhubarb go wild, it might pretty much cover up the whole patch and keep the weeds down till we get back. You see, I’m not convinced we’ll get tenants who are avid gardeners and it would be a pity to come back to a prairie patch!
So this afternoon we’ll be out there dividing the rhubarb and redirecting the strawberries that are spreading out over paths and edges.
What other crop could we put in that takes 18 months to grow? 
asparagus! in fact it might even take longer than that
we had some growing wild at my old house & once established it didn’t even mind being mowed! so it can’t require all that much attention surely?!
tho i’d much prefer more strawberries to asparagus personally..
