11.   Mulch to preserve soil moisture, moderate soil temperature and keep the weeds down.

12.   Mulch will help preserve soil moisture and help moderate soil temperature in summer and winter.

13.   The mulch will keep soil temperatures down during warm weather and enrich the soil as it breaks down.

14.   The soil temperature is more important than air temperature when it comes to coaxing plants to perform.

15.   They lower the soil temperature and, in the case of organic mulches, such as bark and compost, build the soil.

16.   This is one reason we always encourage a good layer of mulch to help retain moisture and modify soil temperature.

17.   It also conserves moisture and maintains soil temperature conducive to the growth of soil building micro-organisms.

18.   The latter is often preferred because of its homogenous appearance and moisture-retention qualities and ability to keep down weed growth and maintain an even soil temperature.
