I just built a nice planter in my garden,
and would like to plant some flowers and edible vegetables (i.e. corn, tomatoes and more). Should I treat the wood and how?
Let me add a few details:
- It's made of heart redwood
- I live in San Gabriel, CA. Not very rainy or cold all year through.
I've been talking to different people and finding info on the internet but none seem to converge to a standard and recognized practice.
Some say that redwood does not rot and the only reason to treat it is to prevent it from freezing and cracking once it absorbs water.
Others say that you should treat it otherwise it will rot and stain.
Another option I was suggested was to use a plastic liner, especially if I want to plant edibles I shouldn't treat it and the plastic liner will prevent it from rot and stain. (But I feel that putting a liner inside would defeat purpose...)
Can anybody please help me figure out which, between all these options (or others if you have any), is the most reasonable thing to do? Considering I would like it to last at least 2/3 yrs and have vegetables growing in it.
Thanks for your assistance!
