For the first time ever, the Pima County Master Gardeners are putting their combined wisdom into a calendar and guide for Sonoran Desert gardeners.
The group has just published its 2016 calendar with basic garden advice, plus short features on topics such as amending soil, shade gardening and using stock tanks as raised beds.
You can also use it as a daily journal to record planting and harvest dates, weather conditions, pruning of trees and shrubs, arrival of insects and changing of irrigation frequency.
In the $10 calendar, you’ll get a sneak peek at new citrus tree recommendations from the University of Arizona and based on the latest research.
For years we’ve been told to fertilize our citrus around 3 major holidays: Valentine’s Day, Memorial Day and Labor Day. But that advice is changing.
Under the revised guidelines, sweet citrus (oranges, grapefruit and tangerines) should receive their third and final dose of fertilizer in May or June, while sour citrus (lemons and limes) should receive their third and final feeding in August or September.
You can buy the calendar at the extension office, 4210 N. Campbell Ave., for $10; or click here for a list of vendors. (Store prices might vary.)
