Roses and mulch - Knowledgebase Question

Las Vegas, Ne
Question by stpaczosa

Just got email from Susan. She says make sure mulch does not touch main trunks. I have just planted a rose and mulched it with shredded Mesquite tree mulch. What will happen because the mulch touches trunks. It actually seems like the rose has quit growing. I have just moved the mulch away from the trunk. Is it only roses that we should keep mulch from the trunk or other plants/trees as well?

Mulch is good in the fact that it suppresses weeds, slows evaporation and helps moderate soil temperatures, but it can also hold too much moisture against the bark of the stems of your plants and trees. Excessive moisture can cause rot so the best approach is to keep the mulch about an inch away from the main stems or trunks of your plants. This way air can circulate around and keep the stems dry. Hope this clarifies things for you.
