English Lavenders can withstand winter in pots and can withstand frigid temperatures and frosts, however, French as well as Spanish lavenders cannot be grown outdoors in winter climates where frost is common and require indoor transport to protect themselves.

Follow this article for the best practices and tips to ensure that lavenders of every species are able to survive winter and last until 15 years..

Ensure Potted Lavenders Survive Winter

All varieties of lavender require some attention and care during winter. This recommendation is applicable to all species of lavender. There are also specific steps to follow to take care of French and Spanish lavenders in winter, If you continue scrolling down.

1. One of the best ways to ensure that potted lavenders are alive through winter is to plant them in a large pot, even if it’s a smaller type of lavender.

The larger the pot the greater amount of soil it will hold. The soil acts as an insulation for roots as temperatures drop and protects plants from freezing.

If you are cultivating lavender in a climate that is colder, the minimum pot size is 16 inches in diameter with an equal depth. This will ensure that the space is adequate to establish roots when the maturation of the lavender.

A smaller pot, the more susceptible the lavender will be to the cold.

2. Another crucial step is to place the lavender in the right soil. The lavender plants require a well-draining soil which does not retain water for long because the roots prefer to dry between sessions of watering. (If you’re not sure you are, I have a guideline on the frequency of watering the lavender).

Pots of lavender are especially vulnerable to root rot during the winter months since the soil is more likely to be cold and remain wet for a longer period of time.

If you have the right preparation, root rot is quickly cured. It is suggested that you plant lavender in soil or a multi-purpose mixing that has been modified with coarse gravel or sand.

The course of sand or gravel can improve the soil’s structure to ensure adequate drainage within the pot. They also don’t hold on to water in the same way that organic compost rich could.

Lavender grows naturally throughout the Mediterranean in sandy, gravelly soil, so it is basically replicating their natural conditions for growing.

One third (33 percent) of sand or gravel to two thirds (66 percent) potted soil is a good ratio to follow when amending your soil. But too much sand or gravel is definitely better than too little when it comes to potted lavenders, so make sure you have plenty of it if you live living in an area that receives lots of rain.

This will ensure that the potted lavenders’ soil drains efficiently and that the roots are free of root rot throughout winter.

3. Another crucial step is to reduce the amount of watering you do over the winter months. If you have left the lavender outside in the pot, it is best to stop watering in the fall, and then not re-water until the beginning of spring.

The lavender is a drought-resistant plant which do not require to be watered often, even in the midst of summer. In fact, excessive water in the water can cause root decay. The lavender can get enough water throughout winter due to rainfall.

If your lavender isn’t cold-hardy and you have moved it inside to guard against frost, it will require watering every 4 to 6 weeks , so that the plant doesn’t dry out completely in the winter.

Specific Steps for French and Spanish Lavender Survival

In colder climates, it is essential for you to take French as well as Spanish lavenders inside during winter since most varieties do not like frost or cold temperatures.

But it is essential that the lavender gets some sunshine, even during winter’s darkest months, so when you take the lavender inside, place it by the most sunny window in your greenhouse, garage or any other suitable space.

The lavender plants are in a state of dormancy during winter, which is why you have be careful about where you put the lavender inside your home. When the plant is placed in the direct line of sight or is forced air or radiators, then the temperature of the lavender can fluctuate dramatically throughout the day.

In dry, hot rooms lavenders might require to be watered every three weeks during winter, but only every 4 to 6 weeks in rooms that have more stable temperatures.

Lavenders prefer some cooler temperatures in winter, as this is a reflection of their natural cycle, and is more beneficial than rooms that are heated to the extreme.

This is why putting your lavender inside a garage could be a great option as in many climates, garages tend to stay at or above freezing, which means they provide protection, but not too hot.

If this isn’t possible, then put your lavender inside a bright window inside the house, ideally free of the direct heat flow and the lavender will be content until they are ready to be taken outside once the weather is warming back up in the spring.

Bring the lavenders inside prior to the first frost, and only water them once every 4 to six weeks. Spanish lavenders are among the most cold-hardy, so you’ll have to bring them inside when temperatures drop below 10 degrees Celsius (50degF) for a prolonged time.
