Watering any plant is always tricky, and lavender plants aren’t different. Common questions I get from readers are; how often should you water lavender plants?
How much water does a lavender need? And how do I water my lavender properly?
I will go into details about watering lavender plants in this article. By the end, you should have the key takeaways on how to fulfill the watering requirements for your lavender plant.
Lavender is a perennial herb that can grow as high as 4 feet tall and as wide.
It has small purple flowers and narrow, gray-green leaves.
Lavender is hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9, and it thrives in full sun or partial shade.
Lavender is a favorite plant to grow in the landscape. The plant has many uses, including as an ornamental garden plant or ground cover.
The plant also has medicinal properties, which make it useful in aromatherapy.
Lavender plants have small, purple flowers that bloom in the summer and fall months. If you want to attract bees and butterflies, lavender is a must-have plant.
There are two types of lavender: English and French.
The French lavender has a much stronger scent than the English variety, but both are easy to grow if you keep them watered properly.
Lavender plants are hardy and generally require minimal care or maintenance.
However, they do require regular watering during the growing season and should be kept away from direct sunlight.
Lavender requires little very little water.
Watering lavender too often will cause the plant to become susceptible to fungal diseases and root rot, so know when to water your plants and how much to give them.
How often should you water lavender plants?
Depending on how old your lavender plant is; newly planted or aged? Where they’re planted; the water requirements is slightly different if they’re planted in pots.
Let’s talk about why they need watering in the first place. Lavender plants are drought-tolerant, but that doesn’t mean they don’t need water.
It’s important to water them on a regular basis when they’re first planted.
Watering lavender plants also will help promote their growth until they become established. In fact, they’re happiest when they have a steady supply of water.
You can tell if your plant is thirsty by looking at its leaves and stems.
If they look droopy or wilted, then you should give it some water.
If the stems are green and healthy looking, then you’re probably good for another week or so without watering it.
You should also keep an eye on the soil around your plant.
If you see any signs of yellowing or browning as far down as one inch below ground level, then you need to give it some water!
How Often to water lavender?
The amount of water needed is dependent upon the type of soil in which the lavender is planted, how much sun the plant receives and the temperature range during the growing season.
When planting new lavenders, give them plenty of water until they become established – at least two weeks or up to three months depending on how warm it has been during this period.
The soil conditions
If your soil is dry, water your lavender plant every seven days.
If it’s not dry, but getting close, give it a drink every six days.
If the soil is moist or damp, wait until seven days have passed before watering again.
Once established, most types of lavender plants only need watering 1-2 times per month for long periods of time without rain or irrigation (depending on how hot/dry it gets).
This usually means watering once every 10 to 14 days or so during hot weather (summer).
If your area gets colder winters and you don’t get enough precipitation, then you’ll need to increase your watering frequency accordingly (more frequent).
Lavender Water Requirments Based On Season (Spring, Winter, and Summer)
Watering Your Lavender Plants in the Spring:
In springtime (or early summer), your garden may be filled with new growth and blooming flowers.
This is also when you should start watering your lavender plants well so they develop healthy roots and leaves before they start growing again in late summer or fall.
Watering Your lavender in Summer:
Lavender plants prefer cool temperatures during the day and warm temperatures at night — or at least 70 degrees Fahrenheit during the day and 60 degrees Fahrenheit at night — so if it’s hot outside for long periods of time (more than one week).
Lavenders are drought tolerant plants that prefer well-drained soil and full sun exposure.
To ensure that your lavender thrives in your garden, water it regularly during the growing season — from April through September — but avoid overwatering the plant at all costs.
As with most plants, overwatering can kill a lavender plant because excess moisture causes root rot, which prevents nutrients and oxygen from traveling up through the roots of the plant and reaching its leaves.
Too much water can also lead to fungal growth on leaves and stems as well as root rot, so make sure you don’t overdo it when watering your lavender plants!
Lavender is a plant that requires very little attention.
They are very easy to care for and can be a great addition to your garden.
They can grow in almost any type of soil and survive in low temperatures, so they make great additions to your garden even if you live in a colder climate.
The most important thing you need to do when growing lavender is water it regularly, but not too much!
That said, you’ll want to keep an eye on your lavender plants to make sure they’re getting enough water.
Lavender Care Instructions
To prevent ending up with an underwatered or overwatered lavender, here are some TLC tips to keep in mind.
After sowing, water once or twice a week until the plants are developed.
Water matured plants once or twice a week until buds form, then every two or three weeks until harvest.
Water lavender in the morning or evening when temperatures are cooler, but never during the heat of the day when temperatures are above 90 degrees Fahrenheit (32 degrees Celsius).
Watering lavender too often will cause it to become susceptible to root rot and fungal diseases such as botrytis blight and powdery mildew. (Overwatering is sometimes indicated by yellowing foliage.)
Apply at least 1 inch (2.5 cm) of water once every 10 days or so, depending on the weather conditions where you live — for example, if it’s hot out and there’s no rain in sight for several days then you may need to apply more frequent watering than once every 10 days.
Lavender plants should be watered every 10-14 days in most regions of the United States.
In extremely dry climates, you may need to water them more frequently—every 7 days or so—and in extremely wet climates, less often—every 14 days or so.
Lavender plants need to be watered frequently, especially when they’re in the ground.
If you’re growing them in a container, you’ll want to water your lavender every few days or so.
If you’re growing your lavender in a container, it’s important to keep the soil moist, but not too wet.
Watering too much can cause the roots to rot and kill your plant. It’s better to water less frequently than more often, but try not to let the soil dry out completely between waterings.
If you’re growing lavender in a pot outdoors, make sure that you do not over-water or let it get too dry between watering sessions.
If you notice that your lavender plants are wilting, it’s likely that they need some water.
If they go two weeks without any water and do not recover after a good watering, then you may want to consider transplanting them into new soil or taking cuttings from them and starting new plants in new pots.
