'Tis the season to get your green thumb on.

Take Advantage of the Fog
Don’t let SF’s epic fog get your green thumb down. Flora Grubb Gardens offers classes where you can learn to design a vertical garden with fog-friendly air plants—hundreds of small, fuzzy varieties adapt well to any surface—and epiphytes such as Spanish moss, ferns, and orchids, which soak in nutrients through their leaves when attached to host plants.

Grow Your Vegetables
Wondering why your lettuce keeps wilting or whether your puny tomato plant will ever bear fruit? Get help at Garden for the Environment, where a class in organic vegetable gardening will guide you on plants that thrive in your neighborhood’s microclimate. After all, your shade-seeking Western sword fern that relishes the haze of the Outer Richmond won’t fare as well in sunny Bernal Heights. You’ll also learn how to rid your garden of pests the natural way. ($25)

Meet the Farmers
Find out where 
Bi-Rite’s succulent berries came from with a day trip to a farm in Watsonville, hosted by 
18 Reasons, the nonprofit community center in the Mission. The Mid-Summer Sweetness excursion takes you to two organic farms where you can amble through berry patches on a tour with the farmers. After, enjoy a boxed lunch from Bi-Rite Market. ($50) July 21;
