As winter sets in Las Vegas, homeowners often underestimate the specific care their trees require during these cooler months. While our desert climate is milder compared to harsher regions, the winter still brings its own challenges. Knowing what your trees need during this time can ensure they flourish when spring arrives.

Trees Suitable for Limited Water
Desert Willow, African Sumac, and Oleander
The Desert Willow, African Sumac, and Oleander thrive in low water conditions. During winter, it’s crucial to monitor their water needs closely.
Reduce watering frequency, but provide enough moisture to avoid root desiccation. As temperatures dip, these trees enter a dormant phase and don’t need much water. It's also important to clear away fallen leaves and debris from around the base, as this helps prevent potential disease. For example, Oleander plants can lose about 25% of their leaves in winter; clearing these can improve airflow and health.

Drought-Resistant Trees
Olive, Blue Palo Verde, and Mesquite
The Olive, Blue Palo Verde, and Mesquite are superb options for drought-resistant landscaping. While they may require less overall care in winter, some attention can significantly contribute to their health.
Winter is an ideal time to trim and prune any dead or damaged branches. This practice improves air circulation and encourages growth. Water these trees sparingly; studies show that too much water can lead to root rot, even in resilient species. Checking moisture levels is key, as overly dry soil can stress them, with signs of stress appearing when soil moisture drops below 20%.

Native Trees and Shrubs
Chaste Tree, Cherry Plum, and Southern Magnolia
Chaste Tree, Cherry Plum, and Southern Magnolia add beauty and unique features to your yard. Though winter typically involves minimal maintenance for these trees, they still need some care.
Make sure these trees are mulched adequately to conserve moisture and regulate soil temperature. A thick layer of mulch can reduce temperature fluctuations by up to 10%. This is especially important for the Southern Magnolia, which thrives in well-drained soil. Additionally, inspect for potential pest infestations. Early detection of pests can prevent damage before spring growth starts.
Exotic and Unique Trees
Joshua Tree, Tree of Heaven, and Velvet Ash
The Joshua Tree, Tree of Heaven, and Velvet Ash offer remarkable shapes and textures to your landscape. Although they are generally low-maintenance, winter care should focus on checking for signs of stress or damage.
Pruning is essential, especially for the Velvet Ash, which may attract pests if it doesn’t have good air circulation. If any branches are damaged by wind or cold, remove them promptly. It's also wise to check moisture levels; even winter-resistant trees can benefit from occasional watering, particularly if rainfall is low.

Flowering and Fruiting Trees
Yellow Trumpetbush, Date Palm, and Japanese Privet
Yellow Trumpetbush, Date Palm, and Japanese Privet bring vibrant colors and textures to your yard. Although these trees are low-maintenance in winter, certain practices can enhance their health.
Ensure these trees are well-mulched to protect their roots from temperature changes. For instance, a depth of 2-4 inches of mulch can help maintain soil warmth. Pruning should ideally occur in late winter or early spring before growth resumes. Regularly inspect for signs of frost damage; the Date Palm can start to show stress when temperatures drop below 30°F.
Tolerant Trees for Various Conditions
Siberian Elm, Texas Ebony, and Honey Mesquite
The Siberian Elm, Texas Ebony, and Honey Mesquite excel in various conditions. Though winter means less care is needed, consistent monitoring is valuable.
Perform light pruning to remove any diseased or dead branches, promoting better growth as spring approaches. Water sparingly and check the soil for moisture levels frequently. If heavy snowfall occurs, gently shake off excess snow to avoid limb breakage, especially above 4 inches of snow.
Keeping Your Trees Healthy
Caring for your Las Vegas trees during the winter months is essential. Each tree species has unique requirements, and understanding these can prevent stress and damage when temperatures drop. Regularly monitor water levels, maintain proper mulch, and prune when necessary.
