Need as much help with wood help and building raised beds ASAP
I need some help with making raised beds. I'm from Toronto, Canada. I think I'm in zone 6a.
Ok, I'm looking to make raised beds in the backyard. I'm looking for a total of 4 with the aquaponic greenhouse in the middle. Right now because some neighbours long ago imported some wood (or salvage wood) which had termites the neighbourhood was under termite control a long time ago and involved the University of Toronto and I think the City of Toronto to go around doing termite testing. Because of this I can not use salvage wood as I'll have neighbour/hood down pressure because of the termite thing which everyone is already bitter over having to have called for inspections and such.
I'm looking to use cedar as man made wood is uber expensive. I need some wood experts here as I spoke with a CSR at Home Depot @ St. Clair and he recommended me use 'deck board' cedar as the cheaper option to 2" x X" x 8'.
Because of the threat of termites my options are limited to man made wood, cedar, or brick/stone/concrete.
With 5/4 x 6 x 6 it is already ~$16
I'm looking to make 4 raised beds at 3' x 8' with probably 10-16" deep as that would give me the most planting options as I've got root and above ground crops. Could some one help me out if I went with the deck board what size posts would I need to screw those deck boards into and what length screws will I need to get a secure screw into the board? Also longest lasting screws or mid grade ones.
How long does untreated cedar last? I don't want comments on this from those without experience with cedar making suggestions. I'd like real world stats if you could. Yes I know some years it's more wet then others so a ballpark from experience would be nice. I'm thinking I may use linseed oil to coat the cedar which on the flip side may give me 1-2 yrs longer on the other end of the line.
Thank you kindly in advance.
I do need help on this ASAP as I've got ~4cu. yard of compost in the backyard which I think rabbits borrowed into over the winter when the trap flipped over I saw holes in it. I'm going to get another 3-4 cu yard of compost this year from the city so I can complete this project. Without the raised beds built first I can't move the compost pile.
Oh yes..will 3-4cu yard of compost be enough to fill 2 3' x 8' grow beds at the depths I asked for? What if I added 2 x 3.8cu yard of peat moss to each bed?
Thanks and sorry for the long post. Had to spit everything out quickly which I had the questions fresh.
I need to get at least 2 beds done before May 4/2010 so I can ready the area to recieve more compost from the city to fill the other 2 beds. The compost from the city is well broken down already.
