I plant drought-tolerant shrubs in my San Francisco backyard. And drought-tolerant bushes and drought-tolerant flowers and veggies. California by no means has a lot rain within the summers, however, in recent times, the autumn and winter rains are additionally slowing. That has induced a number of successive years the place the state is formally in a drought, making a drought-tolerant yard important.
Within the years I’ve gardened, I’ve come to consider within the energy of nature to make it via. However I discovered this yr that even nature won’t be capable to work with local weather change. And that drought-tolerant crops can’t really survive a drought.
California’s Drought
The U.S. Drought Monitor – a nationwide weekly map exhibiting components of the nation which might be in drought – started in 2000. Since then, California has repeatedly skilled drought. The longest period of California drought lasted six years, that’s, 376 weeks, beginning ultimately of 2011 and ending in March 2019.
Since 2019, the state has not “recovered” from drought. A lot of the interval between the center of 2000 and the present day in 2022 additionally have been instances of significant drought. Most people I do know with gardens have modified them by changing lawns and shrubs with drought-tolerant crops.
Drought-Tolerant Crops
As a backyard author, I fill my very own backyard with the crops I like to recommend to readers: drought tolerant native crops which have developed to outlive the intervals with out rain. As I clarify once I give excursions of the San Francisco Botanical Backyard, coastal California has all the time skilled scorching, dry summers. It is likely one of the areas with Mediterranean climates marked by dry summers and cooler, wetter winters.
So our native crops have developed to tolerate summers with out water. California poppies thrive all summer season lengthy. California buckeye bushes drop their leaves within the warmth of summer season, going into early dormancy. Succulents retailer all obtainable water of their puffy leaves to entry when there isn’t any rain. My yard is stuffed with native crops.
Drought-Tolerant Limitations
What I discovered this summer season is that drought-tolerant crops have their limitations. I spent the most popular a part of the summer season – from mid-July via August – in San Francisco. Whereas I didn’t water the crops each day, I did give them a drink each week. And once I left for France in early October, the crops have been thriving.
Quick-forward to November, once I returned from France. Sadly, the anticipated rains have been short-lived and the predictable San Francisco fog yielded middle stage to clear skies and scorching solar. The consequence was not fairly.
Crops I’ve had for a decade have been lifeless, from the tippity-top of their blossoms to the crispy foliage to the unhappy, brittle roots. Succulents have been burned, brown, shriveled. Poppies have been lots of lifeless, ferny leaves. Even the ever-blooming salvia crops had misplaced their flowers and could possibly be yanked out, roots and all, with one hand.
So what’s the largest lesson the backyard taught me this yr? That every little thing might be damaged, and that we people can’t rely on nature to restore all of our errors.
