How often should you water hydrangeas. Our article on how hydrangeas should be looked after in the home garden has a detailed section that looks at when, and how frequently hydrangeas should be given water.
This information is relevant for both indoor and outdoor plants, but some of the details do vary depending on your location so advice on this is important to determine if it’s suitable for your climate zone.
How often should you water hydrangeas
Water at a rate of at least 1 inch per week throughout the growing season.
Make sure to deeply water once or twice a week during times of the year when rainfall is less frequent and make sure to apply mulch to offset water loss from evaporation.
Bigleaf and smooth hydrangeas require more water than others so keep an eye on them and provide additional water as needed but all varieties benefit from consistent moisture and mulching.
Plants that Grow as Perennials
Hydrangeas are not a very demanding type of plant and can take care of themselves for the most part.
They do require enough light to grow their beautiful flowers, though keep that in mind if you’re thinking about planting them somewhere indoors.
They do tend to do better outdoors where they have plenty of room to spread out (although they will find a way to grow no matter what).
Depending on which species you’re planning on growing, they may prefer soil with more organic matter and more water or less all-around.
Measures for Prevention and Corrective Action
Don’t look for a specific rule to water your hydrangeas as this would require you to factor in many variables including daytime temperatures, type of soil, amount of shade, and level of precipitation.
Instead, you should let your hydrangeas tell you when they need water. You can do this if you examine their leaves periodically, noting if they are dull or shriveled or if the edges curl or wilt.
Generally, however, you will probably have to water them 1 or 2 times a week during the summer season and not at all in winter.
The Sun’s Impact on Irrigation
Hydrangeas require partial sunlight to grow, too much sun will cause them to wilt and too little sun in their environment suppresses their natural blooming.
This could be because the shrub requires water in order to thrive and without that, it will lose its vibrancy over time.
The relationship between a shrub’s sun exposure and its water requirements is a key one, extra sun dries out the soil, causing drought stress, or lack of water, but also brings with it a whole host of other potential problems.
Giving a lot of water
If you leave a hydrangea sitting in water for more than an hour, it’ll most likely turn brown and will wilt.
If you have excess-water issues, this means that the plant is most likely being watered to death.
Make sure you are careful when watering them and take care not to let the soil stand in water for too long or else they’ll surely die.
Be sure to replenish all the lost moisture as soon as possible.
What time of day should you water hydrangeas?
Hydrangeas love slightly shady spots, so try to place them there if you can. Hydrangeas also wilt easily, which is why they need more water when they’re exposed to direct sunlight.
They prefer humid temperatures, so mist them regularly with a spray bottle filled with water to boost the humidity around your plants and flowers.
The best time of day to water your hydrangeas is either in the early morning or late evening.
How often should I water hydrangeas in hot weather?
If you don’t have a green thumb, your hydrangeas probably aren’t going to be happy. They like bright indirect light and high humidity, but they need regular water in the summertime.
You should try to water them early in the morning or later in the evening to avoid direct sun which can burn their leaves. They’re dormant in winter, so no watering is needed at this time of the year.
How long can hydrangeas go without water?
Hydrangeas are so easy to preserve. They dry in about two weeks and can last for up to a year, but the water-drying method is best for preserving their shape and color.
To water-dry hydrangeas, let them sit in a bowl of fresh water (change daily) for three or four days at room temperature, then remove the flowers; the plant material should remain pliable.
With your fingers, gently pinch off most of the stems to expose just a few inches of stem under the flower head; then arrange by pushing stems into slits cut into an absorbent material such as paper towels or old cotton tights.
Store at room temperature in a dark place with good air circulation until completely dry before sachet packaging in cellophane bags if you prefer.
