When Does Lavender Grow Back (#1 Important Factors To Know)

Although lavender can be relatively hardy, it typically fades in wintertime, leading to the common question: when does lavender grow back?  

In general, after going dormant over winter, lavender will grow back in the spring months. The time of year that lavender will return depends on the type of lavender. English lavender will return in late spring, French lavender grows back in the early spring and Hybrid lavender returns in mid-summer.

While lavender may be a hardy perennial, it is vital to know everything you can about lavender growth and how to take care of it so that you may benefit from a full blooming lavender plant year after year! Read on to learn about when lavenders grow back, when to prune and how to protect your lavender in winter! 

When Does Lavender Grow Back?

In general, lavender will grow back once winter has left and spring has sprung! However, each type of lavender will come back at different times of the year, depending on its species and location.  

When Does English Lavender Grow Back?

English lavender

English lavender commonly grows back in late spring and will bloom between May and June.

English lavender is a very hardy lavender species that thrive in the USDA zones 5 to 8 and even 9. Within these zones, the English lavender is most likely to survive the winter frost and return in spring with full bloom.

If English lavender lives in colder zones, this plant may become dormant in winter, and it could struggle with regrowth in extreme winters.

Due to the hardiness of the English Lavender, it can most often be left outside for the duration of winter and will grow back once the cold season has passed. However, depending on the temperature, a layer of leaves or additional protection could be placed over the plant as added cover.

When Does French Lavender Grow Back?

French lavender

French lavender grows back in the early spring months, shortly after winter.

The French lavender grows best in zones 8 through to 11. Within these zones, the French lavender becomes an all-year-round plant but will peak in bloom between early fall and early winter.

In any zones colder than its ideal, the French lavender may struggle to grow back after winter. Therefore, it is common practice to move this lavender indoors in colder regions so that it can grow back once winter has passed.

When Does Hybrid Grow Back?

Hybrid lavender is a cross between the English lavender and the Tender Spike lavender. This Hybrid grows back around midsummer, with its peak blooms occurring between July and August to late summer.

The Hybrid Lavender thrives in zones 5 to 8. While this Hybrid does have the hardiness of the English lavender, it would be wise to bring this plant in over winter to guarantee regrowth in summer.

Does Lavender Grow Back Every Year?

The lavender plant is known as a woody perennial. This classification means that it can grow back every year, given that it is planted within the correct zone and is receiving proper care.

On average, lavender lives for about five years – this is the expected life span. However, it has the potential to live for around 15 years, and rarely even 20 years, with the correct care.

To ensure lavender grows back, it needs to be planted in well-drained soil that receives full sun.

It’s also vital for perennial growth that lavender plants are pruned after flowering. Pruning will prepare the lavender for winter and will encourage regrowth in spring.

When To Prune Lavender To Ensure Regrowth?

Pruning usually happens after the lavender has completed its flowering phase and is essential to prepare the lavender for winter. It also helps the lavender grow back in spring. However, when to prune a lavender does depend on the type of lavender.

In general, the pruning of lavender growing in warmer climates should be in August. However, in colder climates pruning should be done in spring.

The only tool needed to prune lavender is a pair of pruning shears.

When To Prune English Lavender?

English lavender commonly flowers twice a year.

The right time to prune English lavender is after the first flowering, which occurs in the late spring or early summer.  This first prune will encourage a second flowering in late summer.

In late August, after the second flowering, a full prune is necessary to prepare the English lavender for winter and allow for regrowth in spring.

When To Prune French Lavender?

The French lavender usually sees its first blooms in early spring and can have its first light prune after this. This plant is fragile, so it should only ever get a light pruning that is not too close to the base.

By late August, a more thorough pruning can be done so that the French lavender is ready for winter and can have a fuller bloom in spring.

When To Prune Hybrid Lavender?

The Hybrid Lavender has a long blooming season from the middle of summer through to the end of summer.

After this lengthy blooming period, the Hybrid Lavender will benefit from a thorough pruning. This will ensure the Hybrid lavender lives through winter and has a full bloom the following summer.

When To Plant Lavender?

Picking the best time and place to plant lavender is key for growing a healthy and robust lavender that can survive winter and bloom year after year!

The ideal time to plant lavender is in springtime once the frost has left. It is best to plant a young lavender because using a seed can be pretty tricky to grow. The young lavender should be planted when the soil temperature is around 60 degrees Fahrenheit.

If planting needs to happen during winter, larger and stronger lavender is preferable so that it is sturdy enough to survive the cold.

How To Plant Lavender?

Picking the right place will ensure that lavender has the ability to regrow in that spot for years to come.

Lavender should be planted in well-drained soil that has access to full sun. Lavender should not be planted in moist areas with moss as this could lead to rotting roots.

Lavender is a hardy plant and, therefore, is not too fussy about the soil contents. It can survive happily in soil with very little fertilizer, but making the soil fertile will only benefit the lavender’s growth. 

When planting more than one lavender, the rule is to plant them at least two or three feet apart to make room for maximum growth for each. The new plants should receive water at least once a week so they can establish themselves.

If you are planting young lavender in winter, it is crucial to add some mulch or extra covering so that it may survive the cold temperatures.

How To Protect Lavender In Winter?

Protecting lavender in winter is vital to ensure that they grow back after enduring the cold.

As mentioned previously, English lavender is relatively hardy and can stay outdoors, but an additional protective layer of mulch will help. Any other type of lavender should be brought inside, if possible so that the plant is under the least amount of stress.

Once your lavender is indoors, it is vital that it receives water only when the topsoil starts to feel dry. In winter, they need a lot less water. Be careful not to overwater as this will lead to roots rotting.

It is advised that lavender be kept indoors in temperatures averaging between 40 degrees Fahrenheit at nighttime and 65 degrees Fahrenheit during the day. Do not place them near heaters or by open drafty windows.  

Lavender always needs as much light as possible, even during wintertime. Placing the lavender where maximum light is coming through a window will make for a happy, healthy lavender.

Finally, do not add any fertilizers to the soil of a lavender plant in winter. The lavender will not use the fertilizers, as it is not growing, so it will build up and make the soil toxic.

Lavender can be placed outside again once the winter frost has left and nighttime temperatures go no lower than 50 degrees Fahrenheit.

Conclusion – When Does Lavender Grow Back?

In conclusion, lavender will generally grow back in springtime once the winter frost has left and temperatures rise again. The exact time that these plants will grow back does depend on the type of lavender. English lavender grows back in late spring, French lavender in early spring and Hybrid lavender in mid-summer.

Furthermore, lavender has the potential to grow back year after year for up to 15 years if they are pruned correctly and planted at the right time in the right place. It is vital to provide lavender with some winter protection by bringing them inside or using mulch to make regrowth is possible in the spring!
