Browning spiraea #261988

Asked July 14, 2015, 6:53 PM EDT

I got a goldflame spiraea and a gold mound about a month ago. They looked good but are now starting to have leaves turn brown. It had been a drought year but I water them a lot I see they have grown and keep flowering. It seems the inside of the plant is dying on me. Any advice? I have never had these plants before


Expert Response

Spireas grow well is relatively warm and dry conditions.  They do not want wet leaves all the time or soggy soil all the  time.  That leads to root rots or fungal leaf diseases. 

We suspect that your spirea may be getting too much moisture from rain and watering.  

Never water overhead, i.e. sprinkling or hosing from above.  Apply water to the soil at the base of the plant.  

Most plants grow well with about 1" of water a week.  Supplement rainfall by watering your spirea only when at least the top 1/2 to 1 inch of soil has dried out.

Also, brush off loose leaves and remove dead leaves.
