Divide spring-flowering plants such as iris, Shasta daisy, gaillardia, cannas, daylilies, and liriope.

Pick dead blooms frequently to encourage your annuals to flower more abundantly.

Check trees to see if any limbs need pruning.  Although NOW IS NOT the time to prune, it would be a good idea to mark the limbs to be removed with flagging tape now, while leaves are still on the tree.  This will make it easier to know which limbs to prune during the dormant season.

Fertilize with Iron, if you notice any leaf yellowing on trees, shrubs or other plants.

Check to make sure that established plants are well mulched in order to cut down on loss of irrigation water to evaporation. 

Continue to keep an eye out for spider mites, which can be devastating to plants during the summer heat.  Look for tan speckles on lower leaves and/or spider webbing.  Plants may turn brown and crisp where severe infestations occur.  Hose plants down with a strong jet of water several days in a row to wash the mites off. 

Make sure that fruit trees are getting plenty of water.  Trees that don’t get enough water this summer will have trouble bearing fruit next spring.  Pecan trees, which are developing fruit now, need ample irrigation for proper development of this year’s nuts.

Take a critical look at your landscape now, while at the height of summer development.  Make notes of how you think it can be better arranged; any plants that need to be replaced; any overgrown plants that need to be pruned in the fall; and any areas that need to be adjusted due to family or pet activities.
