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.
