Growing Tips

Difficult Growing for GA

Container Friendly

1 plant per 12” container

When to Start

Spring: Start seed prep (cold-stratification) 3 months before the last spring frost. (Feb 1-20 Jefferson, GA)

Transplant: After the danger of frost has passed (May 1 for Jefferson, GA)

Fall: see explanation below*

 

How to Start

 

Lavender is difficult to grow in GA due to its dislike of humidity. It is also difficult to start from seed as it requires some preparation and it is slow to germinate.

Seed preparation: Start 3 months before the last spring frost. Surface sow, as the seeds need light to germinate, into cells filled with seed starting mix. Place the cells in a plastic bag. It might be good to place the cells on a piece of cardboard to help stabilize the cells so they won’t tip over. Keep the seeds moist but not soggy during cold stratification. Place the bag in the refrigerator for 4-5 weeks.

After the 4-5 weeks in the refrigerator, take the seeds out and let them warm up to room temperature. At this point, it’s still too early to direct sow outside. Start indoors by placing the cells under grow lights. Lavender needs light to germinate.

Lavender likes to germinate at soil temperatures from 75-80 F during the day. A heat mat may be needed to maintain these temperatures.

*Some say you can direct sow in the fall. Just be aware, the seeds will go through the natural cold stratification and should germinate in the Spring. Following the above steps will give you a better chance of getting seedlings.

 

Care

 

Transplant into well-draining soil and a full sun bed. Space plants 12-18 inches apart. Lavender dislikes humidity and overly wet conditions. Let it dry out a little between watering.

Pruning should be done before the growing season, which is late winter to early spring.

 

How to use

There is no real difference between ornamental and culinary lavender. However, some lavenders are better for cooking than others. Lavandula angustifolia is the best for culinary uses. “You want to avoid most other lavender species due to their camphor content. This includes Lavandula Stoechas and Lavandula Latifolia, and Lavandula X Intermedia. Other lavenders won’t hurt you but they will make your food taste soapy or perfumy.”

All lavender can be used in potpourri and soaps.

Lavender tea: Add 2 tablespoons of fresh flowers or 1 tablespoon of dried flowers to 2 cups of boiling water. Let steep for 5 minutes. Strain and enjoy!

My personal experience

Lavender is can be difficult to grow in GA due to it’s dislike of humidity. I was told when I got this variety, Providence, that it tolerated humidity well. And it does. It’s now something like 7 years old (in 2023). I can’t remember exactly what year I got it. I had to repot for the first time this year into a larger pot.

 

As I grow mine in a container, I water almost every day. I prune mine in late winter/early spring, right before the growing season starts.

 

This is it’s second bloom of the year. The first bloom, which was much fuller, attracted all kinds of pollinators. It wasn’t uncommon for me to find a bumble bee sleeping in my lavender in the mornings.

 

The only thing I find difficult about lavender is saving the seeds. (Which is supposed to be easy to do.) I’m going to continue to try to save seeds, but I’m also going to try cuttings. Mine is getting a little woody and I’m concerned it won’t continue to thrive even in this larger pot.

 

Transplanting it into the ground could prove tricky as lavender is very finicky about where it lives. I want to make sure I have another seedling before doing this in case it dies.

Instructions

 

Lavender is usually propagated by division or cuttings but can also be grown from seed. Choose strong, healthy plants. Mark the plants by tying a piece of yarn around the stem.

Allow the lavender blossoms to remain on the plant until they begin to turn brown & seed head develops. Don’t wait until the bloom is completely dry and brown, as the seed head may burst & scatter the seeds.

Cut the seed head and stems from the plant & gather them into small bundles & tie the stems with string. Place the bundle of lavender in a paper sack. Tie the opening of the sack around the stems, so the lavender hangs upside down in the sack. Poke a few small holes in the sides of the paper sack to provide air circulation. Don’t poke holes in the bottom of the sack as seeds will fall out.

Hang the sack in a dark, well-ventilated room. Leave the lavender in the sack until the seeds drop from the seed heads into the bottom of the bag. Discard the stems and other plant debris. Place the dry lavender seeds in paper seed bags. Store the seeds in a dark, cool, well-ventilated area.

Features

  • English: Culinary. Dried flowers and leaves repel moths and can be used in sachets.

Pruning should be done before the growing season, which is early Spring.
