Curious what you should plant in Tucson in January?

January in the low desert is a great time. While the rest of the country is months away from being able to garden, ours are absolutely thriving.

Planting

Cover Crops & Forage

I list cover crops first because I believe they're the most important thing to grow in a regenerative garden.

Without first building great soil, how can we hope to grow anything that's healthy or nutritious?

Cover crops help to add nitrogen and organic matter to soils, break up compaction, increase moisture retention and infiltration, suppress weeds, prevent erosion, and build dang good dirt.

January is a great time to consider fitting in a cover crop cycle before spring comes. By planting cover crops such as oats and hairy vetch in January, you can grow plenty of biomass to chop & drop before spring planting.

Weeding

Weeds to Pull

Mallow

Mallow has a way of taking over Sonoran desert gardens in January, and can quickly become a big plant.

Mallow has some edible value as well as some medicinal value and food for pollinators.

That said, it's not a native plant and can take over your garden pretty dang quick. I find the raw leaf texture to be that of chalk - a lot of calcium probably, and fairly gross.

It's easy to pull, though, and can be chopped and dropped for organic matter.

Spiny Sowthistle

Spiny sowthistle usually starts showing up with a little more force in Tucson gardens by mid-January, though it's likely been around all winter.



You may choose to leave a few around to flower for the pollinators, but this is generally considered a nuisance plant.

While most thistles are edible and spiny sowthistle is no exception, it's frankly way too prickly and angry for me to want to try and cook.

I simply leave these to grow if they're out of the way, and pull them with a pair of leather gloves on when they show up in my garden spaces.
