White) was an editor at the New Yorker and made the magazine what it is today.  After she moved to Maine she wrote about gardens and gardening and garden catalogs.  Elizabeth Lawrence was the first woman to receive a landscape architecture degree at the University of North Carolina.  Elizabeth wrote A Southern Garden, other volumes,  as well as a garden column for the Charlotte Observer for 20 years.  Her garden in Charlotte is in the historic register.  These two women corresponded for twenty years about gardening.  Susan will share pictures of their gardens and their love of gardening.

Consulting Rosarian Tips for August:

It is important to monitor the moisture level in your soil to ensure the soil around your roses doesn’t dry out. Deep water your roses at least twice a week depending on rain conditions and temperatures. Make sure your roses are surrounded with 2" to 4" of mulch to keep the soil cool and moist.

Now is the time to be thinking of your last application of fertilizer. The last application needs to be done by August 15th. Deep water your roses before and after applying fertilizer. The last application is very important as it will help your roses withstand the unpredictable Colorado winters.

Be on the lookout for powdery mildew. Identifying this problem early can save your roses from serious damage. Remove and destroy infected vegetation. 

Aphids can also be a problem as the season progresses. Remove by hand or apply a strong spray of water. Once the aphid has been knocked off the plant, it cannot get back on. Insecticidal soap spray can also be very effective.

For rose questions, contact a Consulting Rosarian in your area.
