7 best citrus trees to grow
“Citrus is important in every cuisine. That bite of acidity brightens food,” Diane explains. But different cuisines use different types. “We wanted access to things like kaffir [aka kieffer] limes for Thai dishes and yuzu for Japanese ones.”
They started planting within days of moving in, eight years ago. Today, recipes and gardening tips go on their popular White on Rice Couple blog (whiteonricecouple.com), which they started in 2008. The two are certainly at zero risk for scurvy, with 21 vitamin C–bearing trees producing, Todd estimates, 600 pounds of citrus per year. But 600 pounds is a lot for two. So they started an informal citrus club—a way to connect with friends, using their copious yield.
“We invite a bunch of people, hand them all brown paper bags, and send them to ‘the farmyard’ to fill up,” Diane says. That’s where 15 types of citrus trees grow, from Eureka lemons to ‘Buddha’s Hand’. Next is a sit-down meal inspired by the citrus in season. Friends leave with recipes and, as long as they’re locals, a bag of fruit (parts of Southern California and Arizona are under quarantine; see sunset.com/citrus-pest). “Citrus is a crop that carries a certain aura of glamour,” Diane says. “And it cheers everyone up, especially in winter.”
1. Soil matters. With nasty clay soil in our yard, we planted a lot of our citrus in raised beds and in pots. Our garden soil is a compost mix from Larry’s Building Materials in Costa Mesa. To improve drainage, we add cactus mix.
2. Plants can get bored with the same food. We use various fertilizers, depending on when we’re buying. Often it’s Dr. Earth Fruit Tree Fertilizer but also bat guano, liquid fish fertilizer, and other stuff.
3. Leaf trimmings from a hedge have a second life. They serve as mulch for shallow-rooted citrus, which needs to be protected.
4. The assassin bugs are plant-protecting ninja. They hang out in our Algerian tangerine. When aphid infestations occur, the assassin bugs wipe them out.
5. Assemble a mostly organic arsenal. For sooty fungus, we use neem oil. And if leaf miners are really hammering new growth, a little Monterey Garden Insect Spray.
6. Exotic fruit calls for exotic wisdom. We turned to an old Japanese gardener when our yuzus didn’t flower. He told us to stress the plant by tying garden string around several of the branches to choke them. A tree often flowers as a preservation mechanism. Breaking off the ends of the branches by hand—instead of pruning them—has the same effect.
7. It cheers up the neighbors. In the winter especially, citrus works its magic.
8. Sharing is easy. A little juice goes a long way in cooking. And so do the 600 pounds grown in our yard every year.
