I am thinking of growing the following in the pots.. any experience, idea on how, and how long., size of pots, concern (pest),etc 1. Garlic 2. Scallions 3. Onions 4. Tomatoes 5. Strawberries also, can they be mixed like (garlic and scallions)?

I planted 2 apple trees I got last fall. This one flowered beautifully this spring and has grown about 8inches so far this year. The past few days I've noticed this condition on the leaves (see pic). There is still new growth without any issue towards the top and outer branches of the trees. I spray with dormant oil over the winter and recently sprayed with Bonide Fruit Tree spray. I haven't seen any insects crawling around. Can someone tell em what disease this is and how to rid my tree of it? Like I said its still growing and the new growth looks good....its just the older leaves from the beginning of spring that looks like this. Thanks! [ATTACH]33042[/ATTACH]
