grass turning black and long time ornamental grasses dying

Asked June 1, 2018, 3:03 PM EDT

Have people reported that their lawn is turning up with black patches of dead grass? Also, I have two long time ornamental tall grasses that are not coming back this year as they have in the past several years, plus three Wine and Roses shrubs that have died after many years. Could it be too much rain?

The black patches in your lawn may be a type of algae or slime mold but we cannot say for sure.
Send us photos so we can see what you may be dealing with.

There could be several reasons for dieback of the grasses as well as the shrub such as winter damage, too much moisture, poor drainage, etc.

Weigela 'Wine & Roses' - In general Weigela is usually extremely adaptable but prefers a well drained soil and full sun. It does not do well in the shade and likes a cooler climate. Often considerable dieback can occur. Also, too much moisture, poor drainage, etc.
