Thanks, Fruitnut! Yes, I have been following your posts. They're always very encouraging; especially to a newbie-gardener. It's exciting to know that I can get that Green Gage Plum tree and possibly grow it a container. Yay!
You've also brought up another valid point, the tree isn't too pricey ($25) but the potting media certainly is. That's one reason why I prefer potting up every year - less media. But my main reason for not wanting to go directly to 15 gal is fear possible diseases. I read that its not a good idea to use too large of a container on a small tree because the roots doesn't use all the media and the soil ends up stagnant? I tend to over-water so having lots of wet soil isn't good.
Hopefully this isn't going to be too dumb of a question - but when I re-pot, can I use some of the same potting media? Or use that same used potting media for another pot/plant? I'd save a lot of money if I could re-use potting media but not sure how healthy that is for the plant.
I made the really dumb mistake of removing an over-watered diseased tomato plant that had fungus and used the same soil on my new tomato plant. DOH! But what if the plant is healthy, can I re-use the potting-mix then?
