Keep your eyes on the nightly lows starting at the end of this month, if you plant to protect your warm season tomatoes, peppers, and basil.
There are zero concerns about your cool season crops, aside from continuously planting and getting them all in the ground so you can start eating leafy greens again!

Weeding
Weeds to Pull
Needle Grama
Watch out for needle grama (bouteloua aristidoides) this month. It's easy to pull, scythe, or weed-wack but it goes to seed rapidly.
![needle grama grass in sonoran desert after monsoon considered a weed](/media/photos/needle-grama-grass-in-sonoran-desert-after-monsoon-considered-a-weed_820w.webp)
thrives on monsoon rain the Sonoran Desert lowlands.
Needle grama is at its worst as a Tucson weed after a heavy monsoon, but won't tolerate winter frosts. For this reason, it will race to go to seed before November.
Just keep it pulled or chopped back until November if you don't want this in your garden, and you're fine. Remember that while chopping back grama may be work, it's also adding carbon to your soil.
Chop it before it goes to seed, and it makes a great mulch of addition to your compost. If nature wants to grow grama, utilize those nutrients to help you grow more of what you like.
Spurge
Spurge will be creeping in October, doing as its namesake "sandmat" suggests and... matting the sand, of course!
![spurge sandmat common weed growing in tucson sonoran desert in autumn](/media/photos/spurge-sandmat-common-weed-growing-in-tucson-sonoran-desert-in-autumn_820w.webp)
The local spurges tend to produce some sticky sap that can gunk up your hands a little if you decide to pull it without gloves. It won't harm you and washes off easily, but your hands will be a little gross until you find a sink.
I really like the spurges and don't usually pull them up. Afterall, there really are no such things as weeds.
Sandmat has a great low growth habit which makes it a perfect living mulch. It's also incredibly easy to smother out with literally any other plant since it grows on the ground. This is why I don't waste any time pulling this stuff.
If you forget to properly mulch and cover you soil, spurge is nature's way of doing the job for you. Mulch or grow plants and you won't have much spurge.
I really embrace this stuff as the natural August living mulch and never fight it. Get roots in the soil and the spurge will just fade away.
