Q.container gardens
I am trying container gardening for the first time. I took plastic 55 gallon drums, split them lengthwise, put multiple drain holes covered with screen on the bottom, sat them up off the ground on cinder blocks and filled with Kellogg outdoor potting mix. My bedding plants, tomatoes, peppers, etc, are doing fine, but seed seem to be taking a long time and are not healthy, any suggestions????

Make sure you are adequately watering your plants. Consistent moisture levels.
Avoid roots drying out or sitting in soggy soil.
