Let’s get one thing straight: gardening in Phoenix, Arizona is not for the faint of heart. It’s not like those dreamy garden tours you see online where basil grows effortlessly in raised beds and tomatoes ripen in mild summer sun. No—here, we garden in a furnace.
But after three years of trial and error, some successes, many failures, and more dirt under my nails than I ever thought possible, I’ve finally started to figure out what works in the desert. Whether you’re just starting out or looking for that “aha” moment, I hope my journey gives you something helpful to hold onto.
First Things First: Know Your Zone
Phoenix sits in USDA Zone 9b and some parts border into 10a, which basically means: our summers are brutal and our winters are mild. That may sound like good news—and it is!—but it also means that traditional gardening calendars don’t really apply here.
You don’t wait until April to plant. That’s already pushing it. In Phoenix, fall and winter are prime gardening seasons. Spring is short-lived, and summer? Well… it tests your soul.
Timing is Everything: When to Grow What
One of the biggest mistakes I made my first year was planting things when the seed packet said to. Bad move. Those packets are written for places that don’t reach 115°F by June.
Here’s what’s actually worked for me:
🌱 Fall & Winter (September – March):
Best Growing Season!
- Leafy greens: Lettuce, kale, chard, spinach, arugula
- Root veggies: Carrots, radishes, beets, turnips
- Brassicas: Broccoli, cauliflower, cabbage
- Herbs: Cilantro, dill, parsley
- Peas (sugar snap, snow) and fava beans
These crops thrive in the cooler months, and I’ve had my most bountiful harvests from November through February. Lettuce absolutely thrives when the nights are chilly and days are sunny.
Spring (March – early May):
Short Window
- Tomatoes: Start early from seed or buy starts
- Peppers: Same as tomatoes—get them in early
- Cucumbers, squash, green beans
By the time June hits, most of these will bolt, struggle, or just give up—unless you’ve babied them with shade and water like I try (and often fail) to do.
Summer (May – August):
My Worst Season (So Far)
Summer gardening here is like playing defense against the sun. I’ve tried growing:
- Armenian cucumbers
- Sweet potatoes
- Roselle hibiscus
- Okra
- Black-eyed peas
- Malabar spinach
These are some of the heat-tolerant champs, but even they can struggle if you miss a watering or forget the shade cloth. This is my first real attempt at summer gardening, and honestly—it’s hard. I’ve lost plants to heat stress, pests, and plain burnout (the plants and me).
My Three Biggest Lessons
1. Watering Is Crucial—But Smart Watering
Overwatering and underwatering are both easy mistakes here. I’ve found that:
- Deep, infrequent watering works best for most crops.
- Early morning is the best time to water (before the sun scorches everything).
- Drip irrigation or soaker hoses make life easier, especially in summer.
If you can see the soil crusting or leaves wilting by noon, you either need more mulch or more consistent watering. I mulch heavily with straw, dried leaves, or pine shavings to retain moisture.
2. Shade Cloth = Life Saver
A few years ago I thought shade cloths were overkill. Now I think of them as essential armor. I use:
- 30–40% shade cloth in the spring and summer
- A-frame or hoop-style PVC structures over raised beds
- Shade to protect tender plants from the 2pm-6pm sun blast
Even just strategically placing taller plants to shade smaller ones can help.
3. Garden Positioning Makes a Difference
Where you put your garden matters—a lot. I learned this the hard way. My first bed was in full sun with zero afternoon shade. Nothing survived past April.
Now, I position my garden beds:
- On the east side of the yard, where they get morning sun and afternoon shade
- Near a fence or wall that can reflect light early and block heat later
- In rows that allow airflow—this helps prevent mildew and overheating
Pests in the Desert: Still a Thing 🐛
Just because it’s hot doesn’t mean you’re pest-free. Here’s what I battle regularly and what I’ve tried:
- Aphids: I blast them with water or use a neem oil spray. Ladybugs help too.
- Squash bugs: These things are relentless. I hand-pick, squish eggs, and rotate crops.
- Leaf miners: Especially bad in chard and beets. I cover beds with insect netting or sacrifice outer leaves.
- Grasshoppers and caterpillars: I’ve used BT (Bacillus thuringiensis) and row covers.
Keeping plants healthy is the best defense—stress weakens plants and invites pests. I also rotate crops every season and try not to plant the same family in the same bed twice in a row.
Final Thoughts: Gardening in Phoenix is Possible—Just Different
Three years ago, I thought I had to grow tomatoes in June, and I wondered why they fried on the vine. Now I grow lettuce in December, start seeds indoors in July, and save the easiest crops for winter.
If you’re new to gardening in Phoenix, here’s my honest advice:
- Lower your expectations the first year.
- Start in fall. Don’t wait for spring.
- Shade, water, and timing are everything.
- Expect to fail, but every failed plant teaches you something.
There’s nothing like harvesting your own carrots or watching bees pollinate your squash blossoms, even if you’re sweating through your shirt while doing it.
Whether you’re container gardening on a patio or starting raised beds in your yard, you can grow food in the desert. You just have to play by the desert’s rules.

FAQs
What crops grow well in Phoenix in the summer?
Try heat-loving plants like Armenian cucumbers, sweet potatoes, okra, Malabar spinach, roselle, and black-eyed peas. Even then, expect to use shade cloth and mulch.
What shade cloth percentage is best for desert gardens?
30–40% shade cloth works well for most veggies. Avoid going too high (70%+), or you may block needed light.
When should I plant tomatoes in Phoenix?
Start seeds indoors in January or buy starts and transplant by early March. If you wait too long, the heat will shut them down.
Do I need to amend my soil in Arizona?
Yes! Native soil is usually compact and alkaline. I use raised beds with compost, native soil, and coconut coir or peat for moisture retention.
