Well Adams County Nursery and Grandpa's Nursery both have excellent bare root fruit trees. Raintree Nursery, One Green World, Edible Landscaping have excellent products too, Trees, plants, you name it. For supplies various places.
I get most from Amazon or start there. Quality supplies at good prices. You can be fooled, prices seem a little higher, but many products have free shipping.
You have to look around. I just picked up 50 pounds of granite to make a gritty mix for under 7 dollars, free postage! One bag limit. Not at Amazon, from a tip in the container's forum.

Cooks Garden has some organic plants and seeds.Others to try are Jung,Gurneys and Territorial Seed. Brady

Thanks guys, very helpful!

Drew: i normally try not to comment on matters that are going to stray off topic, but you got my interest! What do you use the granite gritty mix for, a growing medium, or for trace nutrients, etc?

Yes a growing medium for cacti, and also for a long term potting mix. Most potting mixes break down after a couple of years. Al is famous in the container forum for his 5-1-1 mix, and his gritty mix (see link). But I have since decided to use pumice instead of grit granite. I may use the granite in my rock garden. Pumice used in bonsai mixes and other soil amendments used for bonsai seem a lot better than what Al has come up with. At least for cacti.

Here is a link that might be useful: Al's mixes

Drew51,

Pumice may be a good choice based on weight alone. I tried the gritty mix, 5-1-1 mix, and other organic mixes. I could barely move a 6.5 gallon container filled with the gritty mix. Now I use 14 gallon containers with a mix similar to the 5-1-1 mix. Those containers are too heavy for me to lift, but I can drag those 14 gallon containers easier than the 6.5 gallon gritty mix filled containers. That gritty mix is very heavy.

So, any more catalogs? What's the best catalogs you get in?
