Question
Hi Tom, will it bother a plant to plant it directly into a pressure-treated wood box?  Does the pressure-treating bother the plant?  I want to plant grape vines over my pergola.  My deck is 5 feet off the ground and so I need to plant in boxes - will I have trouble?

Answer
Hi Lee,
Thanx for your question.  A lot of horticulturalists don't recommend planting in pressure-treated wood boxes because there are some chemicals that could be harmful to a plant.  I've seen people plant in them though and have not seen any ill effects.  Was the box made to be a planter?  I can't tell you if you'll have problem because I haven't had the experience myself.  I can only tell you I've heard it can impair or prevent plant growth and I've also heard it does no harm.  You might give the company a call that makes the box and ask them if they have any data on that.  I hope this helps.
Tom
