“What do plants need?” is the guiding question for this sprinkler workshop. Sprinklers, when carefully designed and operated, will help your garden thrive and use less water. This intensive workshop covers basic plant needs, sprinkler system design, and sprinkler system parts such as valves, pop ups, nozzles, and how they work, irrigation controllers and finally, sprinkler maintenance.

Cement is an ancient building material. It is found today in nearly all construction, but few homeowners have ever worked with it. It is messy but not difficult. In this class I will review how cement works, demonstrate how to work with it on a small scale, and help the class make a small stepping stone for practice. Working with bricks and broken concrete will also be demonstrated. Fee includes all materials. Please bring tough clothes and gloves.

Old stone sinks and animal troughs have been used to grow plants for many years. Today, they are scarce and very expensive. But now, we can make them from hypertufa, an artificial medium with absorbent properties similar to tufa rock. It is lighter than regular concrete, and will not be damaged by freezing after it is completely cured.  You will be making a hypertufa planting pot! Hypertufa, a mixture of cement, peat moss and pearlite molded to resemble tufa or crumbling granite, is a fun process for creating “instant antiquities” for the garden.  Beginning with a small bowl or trough, the techniques will be illustrated so you can make larger pieces at home with confidence. All materials are provided, but wear comfortable clothes, a hat and bring water.
