Using living trees instead of fresh-cut trees to decorate for the holidays has increased in popularity. More than half of my local Christmas tree sales are for living trees that will be planted in January.
Because of their waxy needles and high internal pitch, most conifers need surprisingly little water. This is true for the high- country natives like pine, cypress, cedar and juniper. Once these trees reach their mature sizes, they thrive in our arid climate, dry soil and extreme mountain temperatures.sing living trees instead of fresh-cut trees to decorate for the holidays has increased in popularity.

Evergreens do not like to sit in wet soggy soils; the trees’ internal metabolism will slow to an almost stasis-like state. Planted in soil that drains properly, new root hairs and next spring’s candle buds will form successfully. That is why digging the right size planting hole and adding the correct soil amendments are critical to a successful planting.
Six Steps to Plant a Living Christmas Tree
Step 1: The bowl-shaped hole should be the same depth as the root ball, but three times as wide. Plants do not need a deep hole; they thrive when able to stretch out just under the soil’s surface in search of food and water. This is why a bowl-shaped hole promotes the best root development. Rid the hole of rocks and any debris larger than a golf ball.
Step 2: Improve the planting soil by amending with Watters Premium Mulch. Good mulch will keep clay soils loose and aerated; loose granite retains water up around the root ball. The amount of mulch per plant should be equal to the size of the root ball. That is the quantity of mulch you will need to blend into the native soil used to fill in around each plant.
Step 3: Evergreen trees are so sensitive to soggy soil. It is recommended they be planted on a slight mound. Whatever you do, don’t bury the plant; keep the trunk out of the soil. The top of the root ball you see in the grower’s pot should be able to see sunlight once planted.
Step 4: Evergreens need the right plant food for a healthy start. Use my specially blended 7-4-4 All-Purpose Plant Food specifically designed for mountain plants. Just sprinkle the granules on top of the root ball and water in well. The slow-release nutrients promote a deep green color, while encouraging thicker root growth with each watering.
Step 5: Promote deeper roots with Root & Grow. Add this liquid rooting hormone to the water used to saturate the root ball. It forces new root hairs to grow, and more roots mean a more vigorous plant. Use this root tonic once per month until new candle growth emerges in spring.
Step 6: Top-dress the planting area with a 3-inch layer of shredded cedar bark. This layer of nature’s insulation retains moisture, keeps weeds out, and protects from extreme temperature swings. It is like laying a thick blanket over the roots before they are cold and shivering.
Keep the tree moist, but allow it to dry between watering. Give it a thorough soak twice a month through March. Once it begins to develop new growth, bump its water schedule up to twice a week during the first growing season, then once a week thereafter.
Evergreen of the Month
One evergreen with a starring role in the mountains of Arizona is gaining popularity. It’s the Single Blue Pinyon Pine, a local variety whose tidy appearance and unusual blue color give a bold appearance to a rustic tree. It blends well in dry mountain landscapes, with modern settings, and in Mediterranean style gardens. However, this tree is gaining popularity at farmers’ markets for its pine nuts. Even young trees produce pinecones with melt-in-your-mouth buttery nuts. Let it grow wild to 10 feet, or for that groomed Christmas tree shape, prune it right after its spring growth.
Until next month, may I wish my Christian friends a Merry Christmas, my non-Christian friends Happy Holiday, and my Jewish friends Hanukkah sameach. QCBN
