Gardening in Extreme Heat with UC Master Gardener Tips to Save Your Landscape

A scorching summer heat wave is bringing triple digit temperatures and excessive heat alerts to much of California. The National Weather Service is predicting temperatures upwards of 105 and 115 degrees for several days in a row. Many home gardeners are wondering how they can help their plants, trees, or shrubs survive the intense summer heat.

“We are getting a lot of questions from around the state from people worried about how the extreme temperatures are going to affect the plants or trees in their yard,” says Missy Gable, director of the UC Master Gardener Program. “With a little extra planning, you can help your garden beat the heat and survive the hot summer weather.”

 

UC Master Gardener volunteers are available to help answer gardening questions and provide advice. Here are seven quick and easy ways to help make sure your plants and trees survive the hot summer months:

1. Take care of yourself first, only garden during the cooler times of the day in the early morning or evening hours. Limit the time spent outdoors during the peak temperatures. Drink plenty of water, wear lightweight loose clothing, a brimmed hat, and work in the shade whenever possible.
   
   
2. Shade your plants. Use a shade cloth, patio umbrella or other temporary structure to protect sensitive plants from the direct sun. This can reduce the heat stress on plants and prevent scorching of leaves.
   
   
3. Water in the morning. Watering plants in the early morning helps to minimizes water loss due to evaporation, which is less prevalent during the cooler part of the day. This practice allows your plants to absorb water efficiently and become fully hydrated before the heat intensifies.
   
   
4. Water trees deeply and less frequently. Water trees deeply and less frequently—yes, that's right, less frequently! The key is to water "deeply." Deep watering, promotes a robust network of deep roots, which helps the tree access water from deeper in the soil and become more drought-tolerant.
   
   
5. Mulch, mulch, and more mulch. When temperatures get extreme, having a good layer of mulch prevents soil from heating up excessively and loosing water to evaporation. Apply 4-6 inches of a medium shred bark mulch to insulate the soil. 
   
   
6. Group container plants together: Placing container plants close to each other may help create a microclimate that retains moisture and reduces temperature fluctuations. Consider temporarily moving container plants to shadier areas.
   
   
7. Watch for radiant heat. Pay special attention to plants located near walkways, patios, and other structures that radiate heat. These plants are often the first to show signs of heat stress and may require extra water to cope with the increased temperature.
   
   
8. Don't fertilize plants or trees during hot summer months. Fertilizers aim to increase the growth of plants and trees.  When a fertilizer is applied, especially one that is high in Nitrogen, a plant is triggered to produce more green growth.  An increase in growth means an increase in water and nutrient needs.  During hot spells, it is especially hard to keep up with plant water and nutrient needs as soils dry out quickly and water may not be readily available. 
   
   

Thankfully,

we're not trying to garden on the surface of the sun. Unfortunately, sometimes it can feel like it. Stay cool, and don't forget to plan for your garden in the fall—it's the perfect excuse to stay inside with the air conditioning and an ice-cold beverage.

2,000 Climate-Ready Trees Provided to Residents of Low Shade Neighborhoods

To date, over 2,000 climate-ready shade trees and tips on their planting and long-term care have been provided by UC Master Gardeners and over 20 partners to residents of low shade neighborhoods in San Bernardino and Riverside Counties through the “Trees for Tomorrow Start Today” project. Tree species given away are identified from research projects including the joint University of California/United States Forest Service (USFS) study at UC Riverside as well as from other research, local observations, and input from the green industry and academic colleagues.

The "Trees for Tomorrow Start Today" project was implemented in 2019 by Area UC Cooperative Extension Horticulture Advisor Janet Hartin with support from Mandy Parkes, Inland Empire Resource Conservation District Manager. A "train the trainer" model provided education to Master Gardener volunteers from San Bernardino County on project elements and follow-up. Master Gardeners now manage many of the events. In 2023, the program expanded into Riverside County. Several other Master Gardener programs throughout the state have also expressed interest in implementing the "Trees for Tomorrow Start Today" project.

Why is this project so important? 95% of Californians now reside in cities and suburban environments. Resulting urban heat islands created by built environments coupled with impacts of climate change can be mitigated through nature-based solutions. Planting climate-ready shade trees now will help ensure cooler urban areas in the next several decades as trees mature and maximize their urban ecosystem benefits. Fortunately, the shade from a single well-placed tree can decrease surface temperatures of black asphalt and artificial turf by more than 70 degrees F in hot inland and desert cities. Studies show that surrounding air temperatures can also be reduced through the transpiration process.

A major goal of the"Trees for Tomorrow Start Today" project is to enhance tree canopy cover in low shade neighborhoods also plagued with much higher than average levels of air pollution and pulmonary and cardiovascular disease incidence. Events over the past month have occurred in Fontana, San Bernardino, and the Salton Sea.

Other partners include San Bernardino County, City of San Bernardino, California Climate Action Fellows, Tree People, Coachella Valley Resource Conservation District, Alianza Coachella Valley, Inland Empire Urban Conservation Corps, several water districts, and other groups.  

Thank you to all our partners and, especially, our tree recipients, for greening and cooling your yard and neighborhood! 

 

 

 

 

 

 

 

Pruning Roses and Cultivating Beauty

Pruning roses is not just a chore; it's an important practice for nurturing vibrant, healthy roses and fostering the beauty of your garden. In California, where the climate is favorable for growing roses, understanding the significance of pruning is key to achieving thriving and healthy roses.

 

Why Prune?

Pruning isn't merely about maintaining a tidy appearance; it's about promoting the overall well-being of your roses:

• Annual pruning stimulates plant and shoot growth, leading to larger blooms and a more robust structure.
• Removing dead, damaged, or diseased canes minimizes the risk of fungal infections and pest infestations, fostering plant health.
• Thinning out dense growth improves air circulation within the plant, reducing the likelihood of fungal diseases like powdery mildew and black spot.
• Shaping the plant through pruning enhances its visual appeal, creating a more attractive landscape.

When to Prune

Timing is important when it comes to pruning roses. In California, where winters are mild, the ideal time for pruning is typically between late winter and early spring. Pruning during dormancy allows the plant to focus its energy on new growth when spring arrives.

How to Prune

Pruning may seem daunting, but with the right approach, it becomes a manageable task:

• If the plant is dormant (recommended), remove all remaining leaves.
• Use sharp, clean pruning shears and loppers to make precise cuts, minimizing damage to the plant.
• Trim back old growth by about one-third to improve visibility and encourage new growth. Remove dead, diseased, or crossing canes to maintain a healthy structure.
• Make pruning cuts approximately ¼-1/2” above an outward-facing bud.  Pruning cuts should be at a 45-degree angle, sloping away from the outward-facing bud.
• Create an open, vase-like shape by removing canes from the center of the plant. This promotes airflow and sunlight penetration, which is essential for plant health.
• Clear away debris and old leaves to prevent disease spread. Consider applying insecticidal soap or horticultural oil during dormancy to control pests.

 

Conclusion

Pruning roses is a fundamental aspect of rose care that should not be overlooked. By understanding the importance of pruning and following basic pruning principles, you can nurture thriving roses that add beauty and vitality to your garden year after year. For more details on growing roses and pruning timelines for your area contact your local UC Master Gardener Program.
