Answer: Your plan to rotate crops is a good one. In doing so you'll allow the soil to recover, and you'll confuse the insects. Plan to use only annual flowers (no point in digging up perennials every year!) or use one of the attractive green manure cover crops instead of annual flowers. I like the lavender flowers of crown vetch, but stands of the white flowering buckwheat are beautiful in early summer, too. You can dig the plant residue in at the end of the season to help enrich your soil. The only caution I can offer is to resist the temptation to sow wildflowers. If you broadcast wildflower seeds over the plot you'll be digging weeds for ever and ever!
