This post is in partnership withGilmour Garden and Watering . All thoughts and word are my own .
It ’s here — summertime summer summertiiiime . Or should I say , it’sbeenhere , as we ’ve been feelin ’ the heat for the past few weeks with seemingly no ending in sight .
My eminent desert garden is customary to the sultry conditions this time of twelvemonth , but it ’s not any easier on the plants than it is on me . We have a full south - face garden and July through August are generally the hottest months for us . grim haste this year has mean a dry , dusty summer and rationing of our local irrigation .
In this sweltering weather , keep the garden cool and well - watered is key to helping plant survive . Even with dripping irrigation installed in my yard , I find that I still require to append with hand watering during drought and hotness spell .
Disclosure : If you shop from my clause or make a leverage through one of my links , I may find commissions on some of the products I recommend .
I keep a few band of Gilmour’sFlexogen Super Duty Hosespaired with theirHeavy Duty Thumb Control Watering Nozzlesin different parts of the yard , and have been using them for the past several years to irrigate our containers and hard - to - reach corners .
Having test all eccentric of nozzles over the age , I ’ve discovered that I really care having a thumb ascendency . The pee turns on and stay on , without me need to squelch a induction — no more achy hired man after a Clarence Day in the garden !
It ’s almost life - deepen when you ’re someone who spends a considerable amount of time outside ( and I ’ve actually start replacing all my initiation squeeze nozzles with thisthumb ascendance manikin ) .
I can easy adjust the urine menses with my thumb as I move from industrial plant to establish , and I ’m always a fan of rule nozzles , which put up so much more versatility than a stock sprayer nozzle .
As forthe hosiery , well , it ’s a hosepipe — it work , it ’s relatively lightweight , and so far it ’s burly enough to take some abuse in the garden . ( I am definitely not one to be easy on my gardening geared wheel ! ) The heaviness of the material also seems to help keep the hosiery from kinking .
But the thing I like most about it is actually the impersonal gray color and sheeny covering . While this may sound superficial , the color and covering stand firm scandal very well — a immense plus in my book .
I have some light - colored hoses , and a fragile botheration with them is the fact that they seem to snaffle onto every hint of poop and face really raunchy pretty fast . ( I use and step my hoses , call back ? )
I guess some people would choose function over manikin , but put my hands on a dingy hose deflates the fun of watering a bit ( which , for me , is already more a chore than a meditation ) . So if a hose can last out clean and penetrating - lookingas well asget the problem done , I ’m all for it .
To aid your plants shift to summer survival mode — while being aware of our modified imagination — here are my top seven tips for red-hot weather watering , all gathered from personal experience .
1. Time your watering for the morning or late afternoon.
The best meter to irrigate your garden in summer is from 5 am to 9 am — before the heat of the day sets in , generate your soil plenty of clock time to booze up before the water supply vaporise and any moisture on farewell to dry off before nightfall .
If water in the morning is n’t potential , the next best time — in oecumenical — is from 5 pm to 8 pm . This will bet on your local clime , as people in warm regions will still experience somewhat hot temperatures during those tardy good afternoon minute , and can get off with watering afterward in the eventide .
But unless you endure in an arid mood , assay to ward off watering too deep at night , as cool and wet conditions could encourage fungi andslime mould , lead toincreased slug activity , and invite sow bug , earwig , and other pestilence into your garden .

But all told , do n’t worry if all you may do is a midday watering — any water is well than none at all , and the often - repeated belief that watering on a hot gay day will damage your plants is a horticulture myth that ’s beendebunked by science .
Sunburn ( which often seem as decolor areas on the foliage of young transplantation , heat - raw plants , and distressed , underwatered plants ) is because of simple overexposure to the Lord’s Day , notby water droplets that supposedly magnify the sun and sear the leaves .
Therearegood rationality for not water in the midriff of the day under a blaze hot sun , but leaf scorch is not one of them .
In the cockcrow , the air and ground are cool , which minimizes evaporation . The lack of wind think of you avoid blow water system to wind impulsion .
And most significantly , flora sop up water more readily when they ’re not under heating accent — a condition that ’s more likely to occur when the sun is at its bill .
So while it ’s utterly okay to body of water works while they ’re in full mid - Clarence Day Sunday , it ’s not the most effective direction to go about it .
2. Water well and water deeply.
Just like the great unwashed , plants want thorough hydration during times of excess heat . This is especially truthful of outdoor container plants , as well as new plantings that have n’t yet established their roots .

Container plant — particularly those in smaller pots , framework pots , clay mickle , and basketful lined with coco fibers or bog moss peat moss — are more susceptible to dry out than their in - ground counterpart .
In the height of summertime , these potted plants need extra attention and may require watering every 24-hour interval or even up to three times a day .
A good rule of thumb is to water when the first 2 inches of potting dirt feels dry . The smaller or more porous your container , the more you ’ll have to water it .
Both annual and perennial plants in the ground benefit from a in force deep gazump up to three times a week . appropriate the water to permeate slowly and amply into the soil ( to a depth of at least 6 inch ) encourages roots to grow deeper and strong and protects them from the baked filth surface .
commend : Infrequent mystifying soak are better than frequent light sprinklings . Aim the water decent where it ’s needed — at the rootage geographical zone of your plant life — to boil down the chances of runoff and evaporation .
How do you know when to water ?
constitute an “ indicator ” plant in your garden — one with large , succulent leaves that are prostrate to drooping when the soil is wry .
squash rackets and melon are good indicator plant life , as their leave lose a lot of wet fast . When you see your squash racquets leave-taking start to droop , it ’s a foretoken that your garden could use a adept soaking .
Quick Tip
If your flora look sad and droopy , firstfeel the top couple inches of soil around the source zone . Does it palpate prissy and moist ? If so , more water is not what your plants need ! They are merely coping with the rut and will perk up again once temperatures cool down down .
During periods of passing dry , raging atmospheric condition , I also care to give my plants ( especially the more thin or heat - sore ones ) a gentle overhead rain shower using the “ garden ” arrange on Gilmour’sthumb restraint water nozzle(a full , reproducible spray similar to a soft pelting ) , or scat a sprinkler over my garden bed .
From a conservation viewpoint , it ’s not the most economical role of H2O , but there are times when it ’s called for to upgrade a sizable garden .
In dry , windy conditions , a hunky-dory level of detritus can build up on your plants and cut their ability to photosynthesize expeditiously .
Heat - punctuate plants are also more prone to pests likeaphids , which can naturally be command by a sharp blast of water . ( I wish the “ cat valium ” set on the nozzle for this purpose . )
And finally , a immediate , cooling shower can offer assuagement to a drooping plant , as it helps lower leafage temperature and prevent passion stress .

3. Use drip irrigation or soaker hoses.
Do n’t get me wrong , there ’s always a place for garden hoses and manual lachrymation in the yard ( specially for newly seed layer , youthful seedling , and tempering the event of mad heat wave ) .
But to check that all your flora receive consistent moisture throughout the class , the skilful elbow room to irrigate them is withdrip irrigationor soaker hoses . I put mine on an automatic timer with a rain sensing element , so on days I draw a blank or do n’t have time to body of water , I ’m not worrying about my plant wilting .
If you ’re still hand - irrigate everything , it ’s worth it toinstall a dribble irrigation systemto take some of the workload off in high season .
I like to expend a compounding of dripping lines and alcoholic hoses — they both urine at the stem zone , but emit the moisture differently . Soaker hose are n’t as configurable as drip systems , but are much easier to correct up if you desire to start small first ( or have simple needs ) .

4. Promote high humidity.
Plants that like it humid , such asbananas , fern , peppiness , hibiscus , and elephant ears , should be haze over ofttimes during periods of dry , spicy weather condition .
The “ flush ” or “ soft backwash ” setting on the nozzle are perfect for delivering a touchy , uniform spray of water to these moisture - loving plants .
If it ’s particularly breezy , you may take to mist them a duet time a sidereal day and give the garden a second tearing in the late good afternoon to increase humidity .
Container flora should be grouped together to increase humidity , and they specially gain from being placed under the canopy of enceinte plants or trees .
5. Shield heat-sensitive plants from excessive sun.
A oestrus waving is heavy on new transplants that have n’t had time to develop a strong root system ( including drought - tolerant transplants , which — contrary to popular belief — still require unconstipated watering for the first class while they get established ) .

If your works are in container , move them to an area of the M that ’s partially fill in in the afternoon . Transplants that need to go in the ground earlier than later should behardened offfirst , then planted in the garden where they get only dappled light or afternoon nuance .
develop new transplants next to marvellous annuals or deciduous perennial that offer some screen . By the time the new plants make roots and require full sun , those taller plants will have died back .
Other plant life in the footing can be protect by shade cloth or row cover charge , which still lets in light and water but lug a specific amount of sunlight ( called a “ shade agent ” ) from 25 pct to 90 percentage , depending on its configuration .
recommend shade material covers :
pass a bit of good afternoon shade is a good idea even forheat - loving leafy greensorheat - tolerant loot , as it extends their season and keeps them frombolting too early .
In a pinch , even a white ( or light - colour ) seam mainsheet string across your garden bottom or draped over your plant cages will work . The sheet lets in all the warmth and light of the day while shading your plants and reflecting light off of them at the same time . ( If you do n’t have any erstwhile seam sheets position around , tick off your local thrift shops . )
6. Don’t fertilize during a heat wave.
Very gamy dirt temperature ( above 85 ° farad ) can cause plants to go semi - dormant , so they expend very few nutrient while they ’re in survival modal value and are n’t prepared to make use of them .
If you fertilise your plant while they ’re stressed , it may even damage them . Sounds counterintuitive , right ? Butfertilizing emphasise plants just stresses them even more .
That ’s because fertilizers fuel new increase , and a oestrus - try plant plainly can not keep up with the pressure of putting out new leave . An increase in the amount of weewee needed to move nutrients through a works can also take its cost if a plant is already suffering from ironic or inconsistently damp grunge .
Withhold the fertilizers ( or hold a unaccented diluted solution ) until the weather condition cools off a chip and your works have a chance to recuperate .
When I need to give my works a nimble nutritionary boost in high summertime , I verify the dirt is equally moist first ( to repress heating system stress and meliorate preoccupancy ) and use a half - strength constitutional liquid fertilizer right at the tooth root zone .
My go - to smooth feed isthis fish and seaweed emulsion , which I ’ve used all over my vegetable garden for year .
7. Keep as much moisture in the ground as possible.
This really should be the number - one tip , but I trust that sum it last ensures you wo n’t forget it !
Anorganic mulch like shred barque , arborist wood flake , or straw(not run - of - the - mill hay — you do n’t want to preface all those weed seeds to your garden ) conserves moisture , welter weed , regulate ground temperature to keep plant roots coolheaded in summertime , and adds little total of nutrient to the soil as it breaks down .
It also prevent grime ( and whatever fungi and bacteria are footle in the land ) from splashing up on the farewell while watering , which reduce the spread of disease .
impart a 2- to 3 - inch level of mulch on top of the ground , being careful not to throng it up around the base of your plants ( as it can hold too much wet against the stems and moderate to rotting ) .
An initial covering of mulch should take you through one full time of year , but you should replenish the mulch as necessitate throughout the year .
During intensely hot weather , do n’t be afraid to layer it on thicker — up to 4 column inch , if needed , to shade off the stain from heat and Sunday .
Common questions about watering in hot weather
Is it bad to water plants with hot water?
It ’s probably happened to all of us at some point : You left the garden hose out in the sun all day , then turned on the water and unwittingly showered your industrial plant with hot piss . Are they doomed ?
Well , it depends . Boiling hot water is a very in force remedy for controlling weeds and pest when poured instantly on them .
But … If the hot water merely splashed on your flora or landed on the leave-taking for just a couple seconds , your plant will likely hold out . If the live water ended up on the soil only , then it ’s even less of a concern .
As long as the soil was mulch to protect the crown and beginning of the plant life from overheat , and the foliage stay dry , it ’s okay if you ( unintentionally or not ) irrigate your plant with hot water supply .
How hot is too hot for plants?
In temperature that are systematically above 85 ° F , most industrial plant set out to lose wet tight , a condition that ’s manifested by a flag leaf .
This is also the tipping full stop for vegetable crops like tomatoes , squelch , and Cucumis sativus , which may not blossom or fruit in excessively hot weather .
What do overwatered plants look like?
When a plant is overwatered , the color of the leaves starts to change . You might see splotches of chicken appearance on the surface , or vivacious green leaves turning pallid green or yellow .
This happen because the plant ca n’t photosynthesize the right way when the grime is too wet . Plants need oxygen and overwatering in effect suffocate them .
How much water do vegetables need in hot weather?
A general rule of thumb is to give your vegetablesat least1 inch of water per week , either by rainfall or irrigation . In ironic climates or juiceless sandy territory , double that number ( up to 2 inch per week ) .
And in blistering atmospheric condition , vegetables need even more water , up to a 1/2 column inch extra per week for every 10 degrees that the ordinary temperature is above 60 ° degree Fahrenheit .
you could calculate the median temperature by adding the daytime high school plus the nighttime low , then fraction by 2 . So if your daytime high is 95 and nighttime Sir David Low is 70 , the norm is 82.5 . In this case , your garden would need at least another column inch of weewee in crown summertime .
Does watering grass in the sun burn it?
Even if you water your grass on the red-hot , sunniest day , your supergrass will not burn up . In fact , it will only make it salubrious .
Just like the myth about watering leave of absence on a hot day , H2O droplets on grass will not overstate the sun and scorch the blades . You ’re more likely to burn your gage bynotwatering during utmost heat , or by utilise too much plant food .
