This post is in partnership with Gilmour Garden and also Watering. All thoughts and also words room my own.

It’s here—the dog days of summer. Or have to I say, it’s beenhere, together we’ve to be feelin’ the heat for the past couple of weeks through seemingly no end in sight.

My high desert garden is accustomed come the sultry weather this time the year, yet it’s not any type of easier on the plants than it is top top me. We have actually a complete south-facing garden and also July v August are normally the sexty months because that us. Short precipitation this year has meant a dry, dusty summer and rationing that our regional irrigation.

In this sweltering weather, keeping the garden cool and also well-watered is vital to helping tree survive. Even with drip irrigation mounted in mine yard, I discover that ns still should supplement through hand watering throughout drought and also heat spells.

I save a few sets the Gilmour’s Flexogen supervisor Duty Hoses paired through their hefty Duty Thumb manage Watering Nozzles in different parts the the yard, and have been making use of them for the previous several years to water our containers and hard-to-reach corners.

Having tested all types of nozzles end the years, I’ve uncovered that ns really like having actually a thumb control. The water turns on and also stays on, there is no me needing to squeeze a create — no an ext achy hand after ~ a day in the garden!

It’s nearly life-changing once you’re someone that spends a significant amount that time outside (and I’ve actually began replacing all my cause squeeze nozzles v this thumb manage model).

I deserve to easily change the water circulation with my ignorance as I relocate from plant to plant, and also I’m constantly a fan of pattern nozzles, which market so much an ext versatility than a conventional spray nozzle.

As because that the hose, well, it’s a hose—it works, it’s relatively lightweight, and also so far it’s burly sufficient to take some abuse in the garden. (I am certainly not one to it is in gentle on my gardening gear!) The thickness of the material also seems to assist keep the water tap from kinking.

But the thing I prefer most about it is in reality the neutral gray color and also glossy coating. If this might sound superficial, the color and coating resists dirt very well—a vast plus in my book.

I have actually some lighter-colored hoses, and a slim annoyance with them is the truth that they seem come grab ~ above every speck of dirt and look really grubby pretty fast. (I use and also abuse mine hoses, remember?)

I guess: v some people would prefer role over form, yet putting my hand on a grimy hose deflates the funny of watering a little (which, for me, is already much more a chore than a meditation). For this reason if a hose deserve to stay clean and also sharp-looking as fine asget the task done, I’m every for it.

To assist your plants switch come summer survive mode—while gift mindful the our restricted resources—I’ve partnered through Gilmour to bring you my optimal six advice for warm weather watering.


1. Time your watering for the morning or so late afternoon.

The finest time come water her garden in summer is native 6 to be to 10 am—before the heat of the work sets in, offering your plants plenty that time come drink up and also any humidity on the leaves to dry off prior to nightfall.

If watering in the morning no possible, the next finest time is native 4 pm to 7 pm.

Unless friend live in one arid climate, shot to prevent watering in ~ night, as cool and also wet conditions could encourage fungi and also bacteria, slugs and also snails, sow bugs, earwigs, and also other pests into your garden.

But all told, don’t issue if every you can do is a midday watering—any water is much better than none in ~ all, and the oft-repeated belief that watering top top a hot sunny job will damages your plants is a gardening legend that’s to be debunked through science.



Sunburn (which often show up as bleached areas on the foliage of young transplants, heat-sensitive plants, and also distressed, underwatered plants) is caused by basic overexposure to the sun, not through water droplets the supposedly magnify the sun and scorch the leaves.

There aregood factors for no watering in the middle of the day under a blazing hot sun, yet leaf scorch is not one of them.

In the morning, the air and also soil are cooler, i m sorry minimizes evaporation. The lack of wind way you prevent wasting water to wind drift. And most importantly, plants absorb water more readily once they’re not under warmth stress—a problem that’s much more likely to occur when the sun is in ~ its peak.

So when it’s perfectly it s okay to water plants while they’re in complete mid-day sun, it’s no the most efficient method to go about it.

2. Water well and water deeply.

Just like people, plants need thorough hydration throughout times of overfill heat. This is particularly true of the end container plants, also as brand-new plantings that haven’t yet developed their roots.

Container plants—particularly those in smaller sized pots, clay pots, and baskets lined with cacao fibers or sphagnum peat moss—are much more susceptible to drying out than their in-ground counterparts.

In the height of summer, this potted plants require special attention and also may call for watering every day or even up to 3 times a day.

A good rule of ignorance is come water when the an initial 2 inches of potting soil feels dry. The smaller or more porous her container, the more you’ll have to water it.


Thumb control Watering Nozzle
Both annual and also perennial plants in the ground advantage from a good deep soaking increase to three times a week. Permitting the water come penetrate slowly and totally into the floor (to a depth that at the very least 6 inches) encourages roots to grow deeper and also stronger and also protects them native the parched soil surface.

Remember: Infrequent deep soakings are far better than constant light sprinklings. Aim the water ideal where it’s needed—at the source zone of her plants—to minimize the possibilities of runoff and also evaporation.

How do you know when to water? create an “indicator” tree in your garden—one with large, succulent pipeline that space prone to drooping as soon as the soil is dry.

Squash and melons are great indicator plants, as their leaves lose a many moisture fast. As soon as you see your squash leaves begin to wilt, it’s a authorize that her garden could use a good soak.

During periods of extremely dry, hot weather, I likewise like to provide my tree (especially the an ext fragile or heat-sensitive ones) a gentle overhead shower using the “garden” setup on Gilmour’s thumb regulate watering nozzle (a full, consistent spray comparable to a soft rain).

From a conservation standpoint, it’s not the most economical usage of water, however there are times when it’s dubbed for to encourage a healthy garden.

In dry, windy weather, a well layer that dust can construct up on her plants and also reduce their capacity to photoyynthesize efficiently.

Heat-stressed plants space also an ext prone to pests choose aphids, which deserve to naturally be controlled by a sharp blast that water. (I prefer the “jet” setting on the nozzle for this purpose.)

And finally, a quick, cooling shower can offer relief to a drooping plant, as it helps lower leaf temperature and also prevent warm stress.

3. Promote high humidity.

Plants that like it humid, such as ferns, ginger, hibiscus, and elephant ears, have to be misted commonly during periods of dry, hot weather. The “flower” or “soft wash” settings on the nozzle are perfect for moving a delicate, uniform spray of water to this moisture-loving plants.

If it’s specifically breezy, you might need come mist lock a couple times a day and also give the garden a second watering in the late afternoon to increase humidity.

Container plants need to be grouped together to rise humidity, and also they especially advantage from being inserted under the canopy of larger plants or trees.

4. Shield heat-sensitive plants from excessive sun.

A warmth wave is hardest on new transplants the haven’t had actually time to construct a strong root system (including drought-tolerant transplants, which—contrary to renowned belief—still need constant watering because that the an initial year or two while they obtain established).

If her plants are in containers, relocate them to an area of the garden that’s partially shaded in the afternoon. Transplants that must go in the ground sooner than later on should it is in hardened off first, then planted in the garden wherein they acquire only dappled irradiate or afternoon shade.

(Quick tip: flourish them alongside taller annuals or deciduous perennials that offer some cover. By the time the brand-new plants establish roots and require full sun, those taller plants will certainly have passed away back.)



Otherplants in the ground can be defended by shade cloth or heat cover, which still allows in light and water but blocks a details amount of sun (called a “shade factor”) from 25 percent come 90 percent, depending upon its configuration.

In a pinch, even a white (or light-colored) bed paper strung throughout your garden bed or draped over your plant cages will certainly work. The sheet lets in every the warmth and also light the the work while shading your plants and reflecting light turn off of them in ~ the very same time.

5. Don’t fertilize throughout a warm wave.

Very high soil temperatures (above 85°F) can reason plants to walk semi-dormant, for this reason they usage very few nutrients while they’re in survival mode and aren’t ready to manipulate them.

Withhold the fertilizers (or use a weaker diluted solution) until the weather cools off a bit and your plants have a opportunity to recover.


Easy to water Watering Can
When I need to give my plants a fast nutritional rise in high summer, ns make sure the floor is evenly moist an initial (to reduce warm stress and also improve absorption) and also use a half-strength organic liquid fertilizer ideal at the root zone. Mine go-to liquid feed is this fish and seaweed emulsion, which I’ve used anywhere my vegetable gardens because that years.

6. Keep as much moisture in the ground as possible.

This really must be the number-one tip, yet I hope that including it critical ensures you won’t forget it!

An essential mulch like shredded bark, arborist wood chips, or straw (not hay—you don’t desire to present all those weed seeds to her garden) conserves moisture, smothers weeds, regulates soil temperature to store plant roots cool in summer, and also adds little amounts of nutrients to the soil together it breaks down.

It additionally prevents soil (and every little thing fungi and also bacteria space lingering in the ground) from splashing up on the pipeline while watering, i m sorry reduces the spread out of disease.



Add a minimum 2- to 3-inch class of mulch on peak of the soil, being cautious not to heap it up about the basic of your plants (as it can hold too lot moisture versus the stems and also lead come rotting).

An initial application of mulch must take you v one complete season, however you must replenish the mulch as necessary throughout the year.
