The supplies that matter most for growing vegetables in the low desert, sorted by job.
Gardening in Phoenix, Mesa, Gilbert, and Chandler isn't like gardening back east. We have two growing seasons, alkaline soil, caliche, 110°F summers, and frost nights each winter (rare in central Phoenix, about 10 a year in the East Valley). Every pick below is here for one of those reasons. Where a specific product didn't stand out, the link opens an Amazon search so you can compare options.
Water is the whole game in the low desert. Get it to the roots, on a schedule, and check before you add more.
Drip puts water at the root zone instead of the dry air, which matters when summer evaporation can empty a bed by afternoon.
View on Amazon →Lets you run drip at dawn, when evaporation is lowest, and change the schedule fast between our 110°F Junes and cool Januaries.
View on Amazon →Phoenix soil can look bone-dry on top and still be wet at root depth, so probe before you water and you'll avoid both wilting and root rot.
View on Amazon →From May through September, afternoon sun scorches leaves and fruit. Shade buys you weeks of extra harvest.
Light 30% shade cuts sunscald on tomatoes and peppers but still lets in enough light for fruit to keep setting into early summer.
View on Amazon →Aluminet reflects heat instead of soaking it up, so the air under it stays cooler during 110°F afternoons than it does under black cloth.
Search on Amazon →Rust-free hoops hold shade cloth up in summer and frost cloth in winter, so one frame covers both of our extreme seasons.
View on Amazon →Native Valley soil is alkaline (pH 7.5–8.5), low in organic matter, and often sits on caliche. Feed it every season.
Native desert soil has almost no organic matter, and working in a few inches of compost each season is the biggest single improvement you can make.
Search on Amazon →A balanced, gentle organic feed suits fast-draining amended beds where nutrients wash out quickly under daily summer watering.
View on Amazon →EDDHA iron stays available at pH 7 and above, so it fixes the yellow-leaf iron chlorosis that alkaline Phoenix soil causes.
View on Amazon →A thick layer of straw keeps summer soil cooler and wetter and evens out soil temperature on our occasional frosty winter nights.
Search on Amazon →Building up beats digging down when you're fighting caliche. Containers work well for patios and small yards.
Building up into a filled bed gets you around caliche and compacted native soil, and cedar holds up well in our dry climate.
View on Amazon →Fabric breathes and the tan color soaks up less sun than black plastic, which keeps roots from cooking on a hot patio.
View on Amazon →Use a real potting mix for herb pots and small containers, because yard soil packs hard and drains poorly in a pot.
View on Amazon →Start fall brassicas in late summer and tomatoes and peppers in late December to mid-January, so you're ready for our short windows.
A fine, sterile mix gives fall broccoli and cabbage starts and winter tomato starts a clean start without damping-off.
View on Amazon →Tomato and pepper seeds started in late December germinate faster with bottom heat, so transplants are ready by the February 15 window.
View on Amazon →Growing your own transplants in cell trays lets you hit Phoenix's tight planting windows with the varieties you want, not just what the nursery has.
Search on Amazon →A few good hand tools, plus one heavy-duty bar for the Valley's notorious caliche.
A trowel, transplanter, and cultivator are all you need for the twice-a-year transplanting rush in raised beds.
View on Amazon →The serrated blade cuts through dry, crusted soil and pops out Bermuda grass runners that creep into beds.
View on Amazon →When you hit a caliche layer, a heavy digging bar breaks it up so roots and water can get through.
Search on Amazon →Gentle, targeted options that leave the lady beetles and lacewings working for you.
Cabbage loopers chew through fall broccoli, cabbage, and kale, and B.t. targets caterpillars without harming bees or lady beetles.
View on Amazon →Covering brassicas and greens right after transplanting blocks loopers, whiteflies, and birds, so you have less to spray.
View on Amazon →Insecticidal soap knocks back the aphid flare-ups that hit Valley greens and brassicas in late winter and spring.
View on Amazon →Our best growing season. Plan for frost nights (central Phoenix rarely freezes, but East Valley areas like Mesa and Chandler average about 10 a year) and a few trellised crops. When to use frost cloth: Phoenix frost dates.
Central Phoenix rarely freezes, but the East Valley averages about 10 freezing nights a year, mostly in December and January, and frost cloth over hoops protects young transplants.
View on Amazon →Snap and snow peas sown October 15–31 need something to climb to produce well through January and February.
Search on Amazon →Start seeds indoors late December to mid-January so you can trial several varieties in the short February–May spring tomato window.
