I just bought a couple of semi-dwarf Mexican lime trees in 5 gal.
containers. I also bought a couple of cedar planters for them. The planters
look like it wouldn't take more than a couple of years before they would
turn into compost from frequent watering. I was wondering if I could coat
the insides with something like Thompson's water repellant to make them last
longer ...... or would it poison the plants? Any comments or tips would be
appreciated. Thanks
