IOWA CITY– Wow. What a spring– or is it summer? Either way, gardens are going gangbusters and it’s a challenge to keep up.
The last average frost date is almost here. It’s May 10 for southern Iowa and May 15 for northern Iowa, though this year, you’re probably safe sneaking things in a few days early. So tuck in those tomato plants, peppers, basil, marigolds, impatiens and others after this date.
Plant gladiolus corms, canna rhizomes, and tuberous begonia tubers now the soil is adequately warm.
