Friend just gave me 3 plants!!!!

So my buddy just gave me 3, 3 month old plants so he says, they look healthy about 1 1/2- 2 feet tall and in 2 - 1 gallon bowl, 2 are in one of the bowls and one has its own, i know these are not big enough pots but i plan on transplanting outdoors and am going to gertens after work to get some soil, i just need some recommendations on cheap but good soil, from what i've read is just dig a big hole and mix the soil and dirt 50/50? theres no preflowers as far i can see and they have just been on his deck... thanks for the help!

I was considering making my own with pro-mix but need something simple as this is my first grow! And is chicken wire neccesary for rabbits and such?

See if your local grow/garden shop has any FoxFarm products. Otherwise I would just get something organic like MiracleGrow Organic. It doesnt have any of the MiracleGrow Chemical Ferts. Like it says "Organic" Also if you can find some kind of organic ferts, like some bat or seabird guano, or earthworm castings, bone or blood meal. Somethin like that to help. You dont really need it, But if you can get it Try it.

Dig the hole about 12-15" in length and about the same depth. Mix your ferts then Fill the hole about 1/4 the way full till the base of the stem is about 3" from top of hole. Place your plant in the hole to measure 3", then finish filling around the rest of the plant til you have about 1" from the top of the hole from the base of the plant. Water, then fill the rest in.

Good Luck
