What to Plant in October: A Fall Desert Garden Guide for Summerlin
October is the desert gardener's favorite month, and if you live in Summerlin it is the best time all year to put new plants in the ground. The punishing heat of July and August has backed off, the soil is warm but not scorching, and cool-season crops planted now grow right through winter. Whether you want a vegetable bed that feeds your family or a water-smart yard that saves money and water, here is what to plant in October and how to do it right.
1. Cool-Season Vegetables Go In Now
Southern Nevada's fall growing season is a gift. Broccoli, cauliflower, cabbage, kale, Brussels sprouts, and Swiss chard all love the cool months, and fast growers like lettuce, spinach, carrots, radishes, and peas will be ready to harvest all winter. Garlic and onions go in the ground now too, and herbs like rosemary, sage, thyme, oregano, and chives settle in beautifully. Use starts for most of these and get them in early in the month, because roots need time to establish before the first freeze, which usually arrives around Thanksgiving in Las Vegas.
2. Trees, Shrubs, and Spring Wildflowers
October is also the ideal month to plant trees and shrubs here. Planted now, a young tree spends the entire fall and winter anchoring its roots before summer heat ever arrives, which is a huge head start for a desert landscape. For flowers, sow native wildflowers now for a spring show, think desert marigold, penstemon, California poppies, and lupine. They bloom when the weather warms and bring the bees and birds right back to your garden.
3. The Water-Smart Opportunity
If you have been thinking about replacing a thirsty lawn, fall is the season to plan for it. The Southern Nevada Water Authority's Water Smart Landscapes rebate pays $5 per square foot of grass you remove and replace with water-smart desert landscaping, up to 10,000 square feet, and the Tree Enhancement Program adds $100 for each qualifying new tree. Two practical notes: you must apply and get approval before pulling out turf, and the finished landscape needs at least 50 percent living plant coverage from the SNWA Regional Plant List. Many Summerlin villages also have design guidelines for front yards, so check your HOA's rules before you convert a lawn.
4. Water Deep, Not Often
New plants in the desert need deep, infrequent watering to push roots downward, not shallow sprinkles that leave them thirsty at the surface. Through the end of October, SNWA's fall schedule allows watering up to three assigned days a week, never on Sunday, then drops to one assigned day a week starting November 1. After you plant, add three to four inches of mulch around trees and shrubs to hold moisture in and keep roots cool.
“A yard planted in October is a yard that rewards you every single season after. It is the one gardening task that pays off while you simply wait.”
Whether you are gardening in a newer village like The Paseos or a mature one like The Trails, the October planting rules are the same.
