Grower Tips
This is a large Snowmound like Spiraea. It is very important to go into the winter with a tightly pruned plant due to the amount of early new growth that it can put on. The early spring flush is bluish in color so do a hard fall prune to take advantage of the sales opportunity that this foliage presents. Plants are late to leaf in spring coming out of winter dormancy. -Be careful not to prune the new growth in Spring as you will eliminate the flowers. -Using a 3-4 month slow release fertilizer may reduce the amount of flush in early Spring
