Now I'm re-working my garden beds to make things more efficient and hopefully easier to care for. Will post and update when it's done (hopefully in a couple weeks). Need to haul in a few truckloads of manure to fill them and top up the old beds.
I can't believe I actually got this done, but here is the photographic evidence!
I took a 4x12' bed out of the front left and replaced with these 3, 3x5' galvanized side beds. I should have been more careful with the math and made them a little longer and narrower - there is only 14" between them, but it should be fine.
Towards the back on that side, I took out a trellis structure that was interfering with my cherry tree, and reduced the size of the bed it was in, added 2, 4x12' beds there. On the right side of the path, I had 4x16' beds, but one half would get watered from overspray from the lawn, so they were difficult to manage. They are now gone and the beds are reconfigured so the two on the far right will get the lawn overspray, and the two near the paver path will get watered with soaker hoses.
Lastly, I built a little "tool kiosk" mostly with scrap, including 4x4s from the trellis structure I took down. I still need to add some hooks and things on the inside, but I love this little shed. Hopefully I'll be much less prone to leaving my tools out in the rain to rust, and my wheelbarrow finally has a home.
Overall, I think this will make everything more productive and easier to manage, so I'm looking forward to the 2019 growing season now!
