I know many customers, like myself, LOVE Oregon for its distinct seasons; we are fortunate enough to truly experience a difference between all four! However, with distinct seasons that means one of which is winter; mostly soggy, sometimes frozen winters–which creates a problem if you like to grow plants that prefer a hot, dryer climate. Despite popular belief, there are quite a few “tropical” plants that you can actually grow here in the valley and enjoy all year round! They may just require a little extra special care during our chilly times, you know like hot cocoa, ear muffs, and a warm blanket…
But, in all seriousness, you CAN grow TROPICALS in Oregon! No, cocoa and a blanket are not the answer, but citrus care is still very manageable. This last Sunday we had the pleasure of hosting John Neeway of WeHoP who gave us the low-down on how to grow citrus! Yes, I said citrus… you know, the pride of warm sunny areas like southern California and Florida… we can do that too!
First thing that you need to know, don’t plant citrus trees in the ground here–unfortunately we can’t just plant, water, and walk away.. BUT we can plant in a large pot and enjoy it outside from May-September! You’ll want to use a fairly large pot and probably place it on a rolling, or another easily moveable, plant stand so that transitioning is easy every year. Obviously citrus love the sunshine, so outdoors for as long as possible is the way to go, but during our chilly times a bright window does just fine. Plus, one of the perks of having your citrus as a houseplant is that when it blooms, you get that fresh delicious citrusy scent without the use of candles or cleaners.
Next thing to make sure of, is that you treat this plant as it would be treated in nature, which means adapt to its year round sunshine schedule as best you can.. Think cactus or succulent care; very well draining soil (NOT POTTING SOIL) and infrequent watering. John recommends using a coarse bark and sand mixture so that little to no moisture is retained around the roots of the tree. If your tree starts to drop it’s leaves rapidly, chances are you’re over watering–definitely err on the side of borderline dehydrating it to death than trying to water on a weekly schedule. *Outdoor planting mediums are preferable to potting soils, and amend with sand, perlite, or coco fiber as needed. Avoid any mix that contains wetting agents or fertilizers!
When fertilizing your citrus, the key is to use a high nitrogen slow release granular formula quarterly, and NOT a water soluble variety; as the soluble kinds tend to burn the roots of your tree. Feel free to supplement with minerals such as iron & manganese as needed. If you start to notice the leaves of your citrus yellowing, this is an indicator of not enough food.
The only other trick to happy healthy Oregon grown citrus is to watch for bug problems. During the times that your citrus is nestled in the house for the winter it becomes especially susceptible to insects. Often times with these pests you don’t notice them until the damage is already being done so don’t hesitate to take preventative action. Horticultural oil or good ‘ol soapy water are the perfect treatment, applied every few weeks or as needed to keep ants, scale, and fungus gnats at bay.
So for those of you who may have missed out on our care class, that’s the basics of Citrus care here in the pacific northwest. Feel free to stop by the nursery and chat with our staff about your care questions or come and pick out the newest fruit in your life! We’ve got multiple varieties of lemons, limes and more, to choose from.
