Sunburn can brown leaves when temperatures suddenly spike
Summer gardening in the Santa Clarita Valley area can be a challenge. There is an astonishingly wide range of microclimates in and around the city. Soils, humidity, sun intensity and even rainfall can vary considerably from one place to the next – sometimes even from one part of your property to another! But being inland chaparral, there are commonalities that make gardening in this part of Los Angeles County harder in the summertime than the rest of the year. Yet, if you love gardening, you don’t have to hide indoors all summer. Just plan around summer challenges. Keeping active in the garden will be good for you, your home, your garden and the environment. Here are some things to keep in mind.
It gets hot!
The sun is intense in the inland chaparral. And we experience wide temperatures ranges that allow cooling at night. Too much sun has been proven dangerous to our skin, and overheating can cause sun stroke. That can make summer gardening less inviting than at other times of the year.
What you can do
This is one of the easier issues gardeners can handle. Simply take advantage of our nighttime temperature drops by working during the cooler hours of early morning and late afternoon. And to make working safer and more comfortable, wear protection. Add a hat, gloves and loosely fitting long-sleeved and leg-covering clothes. These will not only help protect from sun, but from scratches and insect bites. Wear a good sunscreen with a high pH. Closed-toe shoes will protect your feet from injury and absorbent socks will keep them more comfortable in the heat. Drink plenty of water to keep hydrated.
We live in the land of wildfires!*
We were again reminded of our vulnerability, how easily fires start, how much fuel there is out there despite the drought, how quickly they spread, how greedily and cruelly they will consume anything they can, and how willingly they will invade even areas we might have thought safe. We are also learning there is no reliable fire season anymore, so don’t wait around for the autumn Santa Ana winds before you consider making your home safe.
What you can do
Clear any brush surrounding your home. Keep gutters, eaves, areas around your house – especially corners where we tend to pile things up – and gardens cleaned up. Remove wood piles near your house. Design your landscape for beauty, efficiency, productivity and safety. That includes fire breaks in your design, choose your materials and their placement carefully, use low profile plants, avoid highly flammable trees and position irrigation and water sources wisely.
Temperatures have been gradually warming during the past half dozen years. Many insects that used to avoid our frosty winters have expanded their territory into our gardens. We are seeing mealy bugs, thrips, scale insects and more aphids than ever.
Snails are invading northern and eastern Santa Clarita Valley landscapes. And raccoons, not all that common twenty years ago, are now seen everywhere up through Acton. Coyotes and rabbits, mice and rats, tree and ground squirrels, gophers and more are exploding in population and feeding off of our lush gardens as their natural resources are vanishing under housing construction and drought.
Now, diseases that threaten the human and pet population are finding vectors to endanger our health. Mosquitoes are carrying an assortment of diseases rarely seen a decade ago, ticks are doing the same, and bats are bringing rabies into a city previously disease free.
What you can do
Planting, pruning and other garden work will clean your garden and take away homes where pests multiply. Using chemicals will encourage pests to build up resistance and those same chemicals can filter into our edibles, drinking water, entering our food chain and that of friendly wildlife. Whenever possible, use physical barriers to deter pests. Try sticky traps, sound and odor deterrents and if necessary, enclose your most delectable edible and decorative plants in half-inch hardware cloth. Block entry holes into your house where rodents will happily move in and multiply.
Enjoy summer gardening and using your garden
Despite summer gardening challenges, the garden still has a lot to offer. Make time to use your garden. Grow edibles, relax in the shade to reduce stress. Play with the children and pets. Use your pool if you have one. Entertain friends during balmy evenings. And keep your body active and your mind at peace working in the garden. There are plenty of jobs that can be done even during the hot summer months.
What you can do in the garden
Keeping spent flowers cut off of plants before they set seed will redirect that seed-setting energy into more flowering. Pulling weeds while they are small will make the job easy. It will also avoid the big job of brush clearance to keep your home safe if a wildfire should threaten.
New plants can be planted at this time of year, especially California natives, cacti and succulents. They will need to be regularly watered (including the drought-tolerant natives) to help roots settle in, and more delicate plants will appreciate some shading for the first few weeks. Most cacti and succulents love being planted during the dry season of summer gardening, but some may still be burnt when exposed to sudden hot sun. Keep dead leaves, sticks and branches cleaned up to discourage pests as well as eliminating fire fuel.
*An extra note regarding wildfires and fallout
If you have ash on your property from the Sand Fire (or any other), sweep or blow it from traffic areas so it won’t be inhaled or tracked into your house. You can then quickly wash the remaining soot into the soil. Areas directly impacted by high heat will experience deeper effects from fire, but landscapes with ash and soot fallout, will benefit from potassium, phosphorus and magnesium and a number of trace elements, as well as calcium (raising the already high pH of our soils).
Adding compost or soil sulfur will acidify the soil and help neutralize the effect of the calcium if your soil is already high in lime. For the most part, the rise in alkalinity will not be a problem and the rest of the additions will actually help enrich your soil. If your house or garden was directly reddened by Foscheck foam, lightly water the surface, then wash it away with a gentle spray. It is water soluble.
When it is hot outdoors, work inside. It’s a perfect opportunity to list what you want to plant when the weather cools in the autumn. You can also use the time to design/redesign your garden with tough plants, lawn replacements and non-living materials (like colored gravel, decomposed granite, or something more imaginative like shale pieces, recycled tumbled glass and more).
After all, it will be hot again next summer. If the trend keeps up, it may be even hotter and drier than this year. But rather than losing out on one of the most beneficial outdoor activities, summer gardening, adapt to the changes and turn your landscape into a comfortable, productive, fun, sustainable and just plain beautiful place to be – all year around!
