November is a great month for planting cold-hardy plants and winter annuals… and for enjoying your garden! Here’s a look at what you can plant this month, how to cut back on watering, and more.
When I first moved to Tucson, new friends told me that November was their favorite month and I can see why! The weather is typically delightful, and a lot of gardening tasks (pruning, taking care of summer damage, watering, fertilizing) are largely over. It’s time to relax and enjoy your garden.
November Weather Outlook
It finally starts to feel like fall! November’s average highs and lows in Tucson and Phoenix are at least 10 degrees cooler than October’s. Additionally, the sun is less intense as the UV index continues to drop. And those nighttime lows are getting downright chilly!
Here’s a look at November weather averages in both Tucson and Phoenix.

What To Do in the Garden in November
Planting is many gardeners’ favorite part of gardening, and for some of us, planting in containers is our favorite kind of planting. It’s so easy (no hardpan, rocks, or caliche!) and you get instant gratification.
What to Plant in November
November is a great time to add plants to your garden that aren’t frost-sensitive.
- aloes
- cold-weather annuals
- native and cold-hardy shrubs and trees
- ornamental grasses
- spring flowering bulbs
- cold-weather herbs and vegetables
While you can plant citrus trees this month, be prepared to cover them if there is a freeze since newly planted trees are more prone to frost damage.
It’s also time to:
- Sow spring wildflower seeds.
- Move shrubs, perennials, ground covers, vines, ornamental grasses.
- Divide perennials.
Planting Winter Annuals
A visit to most nurseries this time of year will wow you with eye-popping spreads of colorful annuals including pansies, snapdragons, alyssum, lobelia, stock, and petunias.
According to Marylee Pangman, Tucson’s leading authority on potted plants and author of Getting Potted in the Desert, winter annuals should be planted once the nighttime lows are consistently in the mid-fifties, which should occur sometime this month. She’s found that waiting for cool nights will help ensure your annuals are robust and beautiful.
Watering New Plants
Even though it’s cooler, you still need to water new plants more frequently than established ones. Water new perennials every two to three days for the first two weeks.
The University of Arizona recommends watering newly planted shrubs and trees according to this schedule.
| Weeks 1 & 2 | Every 3 – 4 days |
| Weeks 3 & 4 | Every 5 – 7 days |
| Weeks 5 & 6 | Every 7 – 10 days |
| Weeks 7 & 8 | Every 10 – 14 days |
Cut Back on Watering Established Plants
It’s time to harden off your established landscape plants for winter. Cut back on watering frequency but continue to give your plants the same amount of water with each watering. If you have an irrigation system, adjust it to water less frequently.
By the end of November, you can stop watering native succulents such as hesperaloe, desert spoon, prickly pear, barrel cactus, and other cactus. Winter rains normally provide adequate water between fall and spring. Too much water makes succulents more susceptible to winter freeze injury and can cause root rot.

What to Fertilize
Don’t fertilize your landscape plants in November. Feeding them now can encourage new frost-sensitive growth. The exceptions are flowering annuals in containers and potted succulents.
What to Prune
This is not the best time of year to do major pruning since it encourages new growth. But you can prune any dead, diseased, or broken branches on shrubs or trees.
And you can deadhead flowers and snip back annuals to encourage bushiness and flowering.
Check Your Fruit Trees
If you’re growing tangelos and mandarins, check them this month — they may be ripe. But for most other citrus you’ll have to wait a while. Color is not the best way to determine if citrus is ripe. When ripe, fruits should have a pleasant citrusy smell and have some heft when you hold them.
Pomegranates may be ready to eat this month. A ripe pomegranate should have smooth skin, but be lumpy rather than perfectly round. It should feel weighty and make a metallic sound when you tap on it.
Stock Up on Frost Cloth Now
I always find myself surprised by November. I feel like I’ve spent forever trying to keep my plants happy in the heat and now suddenly I’m thinking about protecting them from frost!
The average first frost date in Tucson is December 3, but it can happen earlier. (The earliest freeze on record was October 16th!) According to the weather data on Garden.org, there’s a 20% chance that there will be a frost by the end of November.
You can find your first frost date by zip code here.
So don’t get caught short. Have what you need to protect your plants before the first freeze warning or you may find all the stores have run out.
You don’t have to use frost cloth. Many gardeners improvise with towels, sheets, or burlap but frost cloth has some advantages. It lets in air and light, can be left up for days, and if there’s rain, it dries fast.
Fun Fall Gardening Events in November
While Tucson’s major plant sales are over, there are still loads of gardening classes and events in November. You’ll find an up-to-date list of gardening-related events in our Tucson Gardening Events Calendar.
Don’t live in Tucson? Look for Zoom classes. You can participate in these no matter where you live.
