I'll need a truckload worth of soil this year but I don't want to sacrifice quality.  Do the landscape stores sell quality soil or is it better to just buy bags of branded soil from Lowe's?  When I say landscape store, I'm talking about mountain piles of soil that requires a backhoe to scoop into the bed of the truck.  I've done this with mulch and rocks, but not knowledgeable enough about their soil quality.  Thanks

I would get half a truck load from the landscape place. if you have farms or a sale barn near you try to get some manure to mix with it. that way you know ther is some quality there. then all you need is small pebbles, corse sand, or alot of perlite.

I should add that i do alot of composting as well. i make my own potting mix through the growing season that works alot better than store bought in my opinion.

My soil mix.
5 gal of sifted compost
5 gal of sifted decayed wood chips
8 quart bag of perlite
mix well

Hey Frank does this help.

A truckload will be much cheaper, but may be a pain to work with (moving it around etc).  Making sure that it is weed seed free (if it is possible) is a good start too, sometimes you can find topsoil for sale by new houses being constructed when they are doing the leveling.

You will have much more control over the soil mix if you buy it in bulk.  Many plces will let you specify the proportion of ingredients.

I use my mix for generaly everything with no problems

Thank you all very much!  I'll be using this for potted fig trees.

I'm sure we will get martin liking a light fig. I can sell ice to an eskimo.

This is great.  I'm excited to make this concoction!

I'm going to be making my own this year. I plan on mixing some good screened top soil, peat moss, perlite, pinebark fines, and some horse manure and aged chicken manure.
