I had to google to find out why my radishes were not forming any bulbs. This is what I found.

Strawberries, onions and lettuces are doing great in the pallets. My chives didn't come up and the radishes bolted. The two kinds of parsley are growing slowly.
The plants in the straw bales are looking a little sickly. I'm not sure I conditioned my bales properly. I used organic nitrogen and maybe I didn't add enough?? I'm going to use some miracle grow on the plants and see what happens. And the robins ate all but one of my bean plants.
Planting in these different containers has but fun and educational. The ideas I have given here are quick and easy. The most involved container was the pallet planter. If you choose to plant in tires be sure to put cardboard, thick newspaper or landscape paper underneath them to prevent grass and weeds.
