How You Should Be Watering Lavenders in Pots

Last Updated on August 15, 2022 by Stephanie

Potted lavenders require watering only once a week throughout the growing season for the first two years after planting. Once established, potted lavenders require watering only once every two weeks, if there isnt any rain.

Lavenders are native to the Mediterranean where they flourish in sandy, nutrient-poor soils in full sun with only a less water.

The most frequent reason that for the loss of potted lavenders is that they have been overwatered. One of the most obvious signs of a lavender that has been overwatered is a general appearance of wilting and the leaves turning brown.

At this point, that gardeners often make the mistake that their lavender isnt getting enough water, and end up aggravated by re-watering the area.

Water lavender regularly in the morning , which gives the soil time to dry throughout the day, so that moist conditions dont last for long.

Continue reading to learn the exact frequency you should to water your potted lavenders during the initial year after planting and how often you should water your established lavenders, and how to ensure that you dont over-water lavenders, and which pots are best to grow lavender in…

How Often to Water Lavenders in Pots

When watering lavender, it is important to keep in mind that the plant is indigenous to the Mediterranean and thrives in the suns rays and only a less water in draining, nutrient-poor, sandy soils.

So, Lavenders are more risk of over-watering than under watering when they are cultivated by gardeners.

Established lavenders that are in the soil (at at least two year old) generally do not require irrigation in the majority of temperate climates , and they only occasionally require water in dry conditions.

Potted lavenders require some extra attention and care than lavenders that are planted in the ground because pots are more prone to completely drying out as pots heat up in sunlight which speeds up the drying process of the soil.

Potted lavenders should be watered every two weeks throughout the growing season, using approximately 35oz of water (1 litre) in the event of no rain and constant sunshine.

In the morning, water near the base of the plant, and try to keep the foliage from getting damp.

If the weather is partly overcast and there has been some rain, then the lavender plants in pots wont require any extra irrigation.

It may seem like a lack of gardening, but lavenders thrive in dry conditions and soils that are poor in areas where other plants would die due to their Mediterranean tradition!

The same advice for watering applies to every variety of lavender, as well as their numerous varieties of hybrids.

The only difference that is significant in the care of the potted English lavenders and french or Spanish lavenders is that the English varieties are more resistant to frigid winters, frosty days and freezing temperatures, whereas the less fragile Spanish or french varieties will require an unfrozen environment during the winter.

All kinds are drought-tolerant can are able to thrive in pots and create beautiful scents and beautiful flowers when properly cared for.

Lavenders just moved into a pot will require more attention and care during the first year of they settle into their new surroundings.

Lavenders may suffer from transplant shock when you relocate them to a completely different location such as the garden store to your garden in a different pot. It usually happens about within a week or two after you plant.

Transplant shock can manifest in the form of drooping stems and leaves that appear to be overwatered plant, but it is merely an emotional reaction to the new surroundings and is likely to last for a week or more.

The soil should be watered prior to planting, and then water the bottom of the lavender once youve planted it in the pot. Place it in a sun-lit location.

Dont be enticed to water it more often in the first week after planting. Give it time to adapt to the new surroundings and the signs of shock will fade.

While the roots are growing on the newly planted pot of lavender, its a good idea to water it every each week during the initial 4 weeks following the planting.

After four weeks , you can cut back on watering to once every two weeks during the scorching temperatures of summer. However, when its been raining heavily then you wont need to be watering as often. A lot of water can do more harm than good.

New lavenders are watered in their initial season each 2 months (depending on the amount of rainfall) from September until temperatures drop and the soil isnt drying out as fast. The lavenders are getting ready for a time that will be dormant in winter.

In winter, if you own in your garden an English Lavender variety you can place the lavender pot outside and it will get enough water to allow it to grow in a comfortable manner.

French lavenders, also known as Spanish lavenders however, need to be kept in during the winter months as they cannot take frosts well. They dont require a lot of water during winter, but theyll need it to drink, so make sure they get an adequate drink every six weeks until the spring comes back.

Remember…Lavenders always display their most beautiful display after the very first season of bloom, therefore it is important to wait!

How to Avoid Over Watering Lavenders in Pots

Overwatering is the most serious danger for your flowering lavender. The lavender that is in a damp soil can develop root rot, and eventually will die. But there are ways to reduce the risk of this happening:

  1. Lavenders must be potted in a medium that drains well which contains 1/3 compost and 2/3 Sand or Grit. This mimics the drainage conditions in the Mediterranean which is where they thrive in their natural habitat.
  2. It is essential to ensure that the pot has drainage holes at the base and an area of gravel on the bottom to make sure that they dont get blocked by compacted soil. The ideal is to have the pot elevated so that water doesnt collect beneath.
  3. Lavenders require full sun (preferably at least 6 hours per day in the summer). This helps to remove significant amounts of soil moisture and ensure the conditions are perfect for the plant.
  4. Do not water your lavender more than twice each week. You can also skip watering when there is significant rain and cloudy days.

If you adhere to these steps, you will put up a beautiful display of flowers and emit its unique summer scent.

Choosing the Right Pot for Watering Lavenders

The choice of the best pot for lavenders is essential in terms of watering. The perfect lavender pot should have numerous holes in the base that allow the drainage of water as easily as it can.

The lavender roots will gain when you cover on the base of your pot approximately 1 inch of dirt to create air pockets, to ensure that the soil doesnt get compacted in the bottom, which slows down the draining of water from the pot.

If the roots of your lavender are exposed to moist soil for any period of time, youre at risk of developing root rot that could cause the plant to die.

The pot must have adequate drainage, and it should be at least 16 inches wide and have a minimum depth of 12 inches to hold a mature lavender.

If you are able to keep the pot from the ground by using the help of pot feet (available at garden stores) or supported by stones, this will ensure that the water is able to drain away without accumulating beneath.

Beware of this error!

One common error with potted lavenders, especially if the plant is in a shaded area, is to place plates or saucers at on the base of the pot to prevent the water from spilling out. The accumulation of water in the pot could result in a waterlogged soil and root rot can occur and destroy the lavender.


Key Takeaways:

  • Potted lavenders that are water established should be watered every week for the duration of the summer months if it is dry. do not water if there has been days of overcast with substantial rain in the season of spring or summer.
  • The newly planted lavender plants will require to be watered twice a week for the initial four weeks after planting. After that, it will be once a week during the first year of the pot. Once established, water them twice a week during this growing period.
  • If its an English lavender that you leave outside, you wont need to water it at all in the winter months as they can withstand frost and receive sufficient water to be able to survive.
  • Over-watering lavender is more problematic than under watering since lavenders are drought tolerant and dont like soils that are moist.
  • Spanish as well as French varieties must be brought in during the winter months to avoid frost. They will require a small amount of water every six weeks.
  • It is important to ensure that your lavender is in a sandy soil that has good drainage and is in a sun-drenched location.
