BACKYARD TIP: Whether your water is coming from the sky or from your hose, preserve that precious moisture

by using mulch. A 2-inch layer of organic mulch will go a long way toward keeping the moisture in the soil.

How’s the weather?

That might seem like simple chitchat to most people, but to a gardener it’s the start of a serious discussion. After

all, our beloved flowers are at the mercy of the skies. And every summer, we seem to be faced with extra-hot,

extra-dry conditions that can wreak havoc on our plants. Luckily, though, we have a wonderful range of adaptable

plants to try.

What Is Drought?

Page 2: 40piante Resist Siccità

Before we get to the plants, let’s first look at drought. Usually dry spells are normal, because weather is variable.

But when they continue week after week, month after month or even year after year, it depletes every bit of

moisture in the soil. In short, you’re dealing with a drought.

At this point, watering becomes an endless and expensive chore. Even worse, you might not be able to water at all

if you live in a municipality that has drought restrictions. So what’s a gardener to do?

Add plants! Well, this isn’t quite as simple as it sounds. Sure, a drought mimics desert conditions, but in this case

it’s a temporary desert. Most of us need plants that can thrive in both drought conditions and wetter environments,

too.

This is why you can’t just plant a bunch of cacti or agave. When the rain returns, their roots won’t be able to draw

up the extra water fast enough, and they may literally drown. The key is to have plants that can handle both: They

can shrug off drought, yet they appreciate ample rainfall.

The Time Is Now

When’s the best time to start drought-proofing your garden? Right now! Ideally, you want to get plants in the

ground well before a dry spell hits. So there’s no time like the present to hit the garden center and start adding

drought-resilient perennials to your garden.

Don’t expect them to work magic right away, though. Even the least thirsty plants in the world need moisture to get

their roots established. Expect to water your new perennials for a full year, while they grow the roots they need to

weather a drought without skipping a beat.

What’s Normal?

You probably have a good idea of what a normal amount of annual precipitation is like in your area. But many

years aren’t exactly normal. Besides, the precipitation report doesn’t begin to tell the full story.

In my neck of the woods, on the dry side of the Rockies, annual precipitation is almost entirely snow. Come the

growing season, the sky shuts off like a faucet. Week after week can go by with nary a drizzle, or at most a tease

that barely wets the soil. It’s a similar story in the Pacific Northwest, where winter is the infamous rainy season,

followed by a long, lovely and usually dry summer.

Other parts of the country have a more balanced picture, with water falling year round as winter snow and summer

rain. Still, no matter what the usual cycle of precipitation is where you live, Mother Nature has a habit of throwing a

monkey wrench into the works. So it’s best to act like a Boy Scout and be prepared.

Leaves Tell the Truth

Belowground, it’s roots that help a plant get through dry times. Taproots go deep, as do the fibrous roots of many

prairie plants, so they’re able to draw up moisture even when the top foot of soil is bone dry.

Still, if a plant has big leaves or lots of smaller ones, even a very deep root will have trouble supporting the needs

of the top growth. Hollyhocks, for instance, wilt very quickly in a drought, as do tomatoes.

So instead of examining the roots, take a look at the leaves, which are the main source of water loss. Sun and

wind, plus the normal process of transpiration through which plants breathe, cause water to evaporate. Roots are

constantly working to pull moisture from the soil to replenish that supply.

Drought-tolerant plants have all sorts of defenses to prevent water from being lost through their leaves. That’s why

leaves are the No. 1 clue to how well plants will survive a scarcity of water.

Big green leaves, lush foliage? Times will probably be tough when drought sets in. Small leaves and fewer of

them? There’s much less water needed overall. What about leaves with a coating of fuzz or a waxy layer? These

are great adaptations to prevent water loss.

Start Planting

Both the garden center and a local native-plants group are good places to find drought-resistant flowers and plants

for your area. Be sure to check out our picks (at right), too.

It can take time to switch your plants over to drought-resilient varieties, but it’s a good thing to keep in mind when

adding new perennials to your garden. And it’s a good goal to have in general. After all, if you get the right plants

in place now, your garden will look glorious no matter how stingy nature is with water.
