Lance Walheim might be just about the smartest guy around when it comes to growing citrus in gardens.
Lance is a professional citrus grower, co-founder of California Citrus Specialties, a commercial grower of dozens of citrus, including many lesser-known varieties. He is a UC Berkeley graduate with a degree in botany and the author of over 30 gardening books, including the definitive book "Citrus, A Complete Guide to Selecting and Growing Over 100 Varieties." Lance was staff editor at Sunset magazine for several years and served as contributing editor to the 10th, 11th, 12th and 13th editions of the "Sunset Western Garden Book," as well as the 14th edition, now in process.
For several years I've listened to Lance patiently instruct countless home gardeners on everything citrus, from the best varieties, to methods of planting, fertilizing, pest control, pruning, soil and so on.
Perhaps the two points that I hear Lance emphasizing the most are the importance of the correct variety for each person's unique climate and the importance of choosing citrus varieties that will provide the owner with fruit over a long period, not all at once.
