Last year we built two raised gardens, each 4'X8'. We had torrential rains that spring, and we believe the 'good' stuff leached out of the carefully prepared soil. We had moderate success.
This year, I've mixed plenty of compost from a variety of sources into the soil. I also started seedlings in the greenhouse (I wouldn't even care to imagine the fun Angus the Cat would have had with the seedlings and their pots of wonderful soil had I attempted this in the house), and did my best to get everything in the ground on time.
The tomato seedlings did very well, and I planted 5 in the garden on the right, then put 3 more in pots just because I couldn't stand to toss them out. They're starting to perk up after the transplanting. The largest tomato plants have flowers and the tiniest tomatoes on them!
I added marigolds in and around the garden, as well as a cluster of sunflowers on the far end of the garden. Everything is changing so fast! I love this time of year!
