    Very pretty by the way. I would wait till everything is dormant then replace the timbers on at a time starting with the one at the bottom. This may be tricky but my neighbor did it. If its just the color you don't like wait till they have gone dormant and power wash.

    Check Home Depot or Lowes for PVC outdoor trim pieces.
    Maybe replace or cover with the above.
    Comes in white, used on outside of houses, doors, weatherproof.

    To begin, explain why you want to replace them. ie: damage, color, etc. There may be a far easier solution.

      Deteriorating so they need to be replaced. The bottom row runs along a drainage ditch. My area is blessed with a lot of ground water. I’m interested in your ideas. Thank you for asking.

    You might want to replace pressure treated lumber with blocks or some other stone product because the chemicals in the pressure-treated wood probably leach into your garden. Which in turn go into your plants. You might be eating poison. Check into it

      I worked in the lumber industry before my gardens and kept edibles out of these beds. These have been strictly flowers and shrubs.
      Good point to make for those who might not know. Thank you

    Actually PT lumber in residential use has not contained arsenic for at least a decade. It's only used in commercial lumber (like for bridges, etc.). Regardless, you'll see tons of Yay & Nay articles on the internet. I hope these help.

    Thank you. I’ve had them in my gardens since 2004 so they’ve started to deteriorat.
