The Fourth Annual Encinitas Garden Festival & Tour is set to take place in Cardiff on Saturday, April 25, from 10am-4pm. This celebration of gardening and horticultural heritage features a self-guided walking tour of more than 20 exceptional private gardens in addition to a marketplace of vendors, artists, boutique plant growers, and educational opportunities. Guest speakers will offer seminars on topics such as starting a vegetable garden, getting rid of your lawn, installing a low water landscape, and gardening alongside natural spaces. A portion of the proceeds will go towards the Encinitas Garden Festival & Tour Fund at the Coastal Community Foundation. While the marketplace is free, garden admission is by ticket only. Tickets purchased in advance cost $21 for adults and $7 for children ten and under. The event is expected to sell out. (760/753-8615, www.encinitasgardenfestival.org)    JANE SHIOMI
