These should be pruned off. Remember, now is the time to have this taken care of, not when a hurricane threatens. Despite the intense heat, gardening activities continue through the summer. Make a point to work in the cooler morning or late afternoon hours whenever possible, or in areas of your landscape that are in the shade. Drink plenty of liquids before, during and after working in the garden.
Cold water is best.
Avoid beverages containing caffeine or alcohol as they can contribute to dehydration. Keep up with jobs such as weeding, mulching and staking plants. It is far easier to do these jobs a little at a time as needed rather than getting behind and having to make a major effort. Do not forget to water regularly as needed. This has been an unusually dry spring and early summer, and our gardens, lawns and even trees will need our help if the dry weather continues.
