Why Plant in the Fall?

Glad you asked! It’s the prime time to plant trees, shrubs, and spring wildflowers in southern Arizona. From late September through early December soil temperatures are still warm, encouraging root growth and development. Planting now allows plants to become established before next summer’s heat sets in. Also, with cooler temperatures, plants need less water and it is a much more forgiving time of year to put new plants in the ground. If you forget to water just one day in the summer, your new plants can be toast. From the fall season through spring, water newly planted plants once every 3-4 days and gradually increase the number of days between watering as plants get established. Wondering how to plant? How deep to dig the hole? How to use mulch? Be sure to visit our Water – Plant It Wisely site for plant selection tips, and proper planting instructions.

Always Plan Before You Plant

After planting your desert plants, top with organic mulch before applying granite or rock.

Planning is essential if you want an attractive, easy to maintain, and functional home landscape. Make sure to look at mature plant size and characteristics to determine if their fit and function will work well in your yard.

Water – Use It Wisely Arizona partners have put together great information on saving water outdoors that includes  interactive watering guides, landscaping ideas, low-water-use plants and more.  Also, be sure to explore the event calendar on the Water – Use It Wisely home page and find out the fall landscape workshops we have going on this season!

When you purchase plants for your home landscape, be sure to look for healthy, well-grown plants. Don’t forget to add 2-3 inches of compost or mulch to the surface of the soil after planting and before covering with granite or rock (keep the mulch a few inches away from the stem or tree trunk). Check with your local plant nursery for the best results. Don’t forget to look for local fall plant sales put on by botanical gardens or others. We’ve including a listing of dates and locations below.

What are the Benefits of Low-Water-Use Plants?

This fall, replace your high-water-use plants with water-thrifty ones! Desert flora doesn’t require much water to thrive and adds a variety of colors, sizes, and functions that will spruce up your garden. You will love how your yard looks, how much easier it is to maintain, and how your water bills look. With each low-water-use plant you place in your landscape, you can save up to 550 gallons a year. Considering up to 70% of water use is outdoors, you can brag to your neighbors that your beautiful landscape is not only conserving water but is easy to take care of, too.

Benefits of Low-Water-Use Landscapes

  • Save water, a precious resource in the desert
  • Provide many functions (shade, attracting birds, add color)
  • Easier to maintain requiring less fertilizer, pesticides, and care

Don’t Forget to Plant Seeds

Consider Forgoing the Winter Grass

Are you thinking of overseeding your bermudagrass? While sustaining a lush, green lawn throughout the year is appealing to many home and business owners, the additional water needed for cool-season grasses is difficult to justify when water is such a precious resource. Now more than ever, saving every drop we can is critical as we experience extraordinary drought conditions as well as climate pressures that have triggered water shortages to our Colorado River water supplies.

Need more help to decide whether or not to forgo the winter lawn? First, see the Top Ten Reasons Not to Overseed with Winter Rye. If you decide you still want to overseed, keep it as efficient as you can with the timing, watering, and limiting the areas.

Mexican poppy, lupine seeds, and other wildflowers should be planted in the fall for spring bloom.

Plant Wildflowers

Are you looking for carpets of golden poppies or spikes of violet lupines? Even though they bloom in the spring, fall is the time to sow many of the wildflower seeds in your landscape. If possible try to sow shortly before one of our October or November rains. For good details on wildflower gardening, request our free booklet, “Landscape Plants for the Arizona Desert” or read our blog, “Plant of the Month: Wildflowers!” for more information.

Avoid wildflower or ‘meadow’ mixes from other parts of the country or world. For example, African Daisies are… well, from Africa. Look for quality, locally grown, or collected seed that includes beauties such as Mexican Gold Poppies, Arizona Lupines and Desert Bluebells. The Native Seed Company out of Tucson provides high quality, locally collected native seeds. Seeds are not available for online ordering but can be found at most local nurseries or specialty plant sales.
