Here in RI the rain has been outright unbelievable. For July we've gone way beyond any record for water and yet the plants growing in the raised bed are doing fine. Great drainage with generous amounts of compost to feed the soil. Mulched too. Half whiskey barrels (mini raised beds) are doing just as well. Other gardeners around here are unhappy with flooded soggy gardens where the roots are starved for oxygen, unfortunately. Learned all this great stuff from this forum - priceless.
