Gardening tips For August 2017

Harvest summer crops regularly to promote more production. 

Pinch off Basil flowers as they form to prevent the plant from becoming woody.  

Pick green beans every three to five days while the pods are still tender; if the pods dry on the vine the plant will stop bearing. 

Stone fruit such as apricots, nectarines and peaches are ready to pick when they pull off with a gentle twist; make sure to pick up and discard fallen fruit.

Pull up spent summer vegetables and compost them; if they are diseased, put them in green waste or on your next burn pile.

Occasionally deep water any ornamental and fruit trees during long periods of hot dry weather.

As Master Gardeners we get many questions regarding our native Oak trees; unfortunately many are regarding trees that seem to be dying or are not healthy.

There are many species in our area of the Sierra foothills. The most common are Blue Oaks, Black Oaks, Interior live Oaks, Canyon Oaks and Valley Oaks. These trees are a very important part of the foothill environment and should be treated with great respect.

An important consideration when building or landscaping in an area with native Oaks is to protect the root system and drip line from any construction around them. Avoid changing the grade around the tree.  Most feeder roots of Oaks are very near the surface and can be easily damaged. It is important not to disturb the area within the “drip line” of the tree, meaning anything within the leaf canopy. Oak roots need adequate oxygen and a light cover of decomposing leaves in the drip line area.

Eliminate plantings within 3 to 4 feet of the trunk of the tree.

Most importantly, no summer watering since Oaks survive best with winter rains only.
