How to Grow Lavender from Seed

Posted on March 17 2019

Spring is just around the corner, even if the weather has been a little dodgy over the last few weeks, it will be here before we know it. In previous TreatBoxes we added some lavender seeds and thought it would be great timing to get these planted ready for summer, I put some straightforward tips on the packaging but promised a blog post with full details for anyone unsure, so let's get started.


March TreatBox


After planting some last year and they worked, I could share my steps with you! I know there are lots of ways to germinate the seeds, but this is how I did it... 


  • To begin, you will need a tray or pot. I used a biodegradable modular plate. I filled the tray with compost and moistened with water until nice and damp but not soaking wet. 

  • Next, carefully and taking my time, I separated the seeds and put a couple of seeds in each compartment of the tray then covered each compartment with a very light dusting of compost making sure each grain is covered, do not push down.

  • If you have a propagator, then pop the tray in there, but I didn't have one so a zip lock bag would be great or a plastic bag where you can tightly wrap around the plate. Now keep the plate in a warm sunny position but out of direct sunlight. 

  • It essential to keep the compost/seeds moist but never soaking them! It can take 12-21 days approximately for germination to occur,  not all of my seeds worked, but over half of them did within a couple of weeks.  After doing some research if nothing happens to any of the seeds, you can pop the tray into a refrigerator for 3-6 weeks make sure you keep your eye on them and if any sign of germination starts happening remove immediately. After the six weeks, you can try the process again place them back in a warm and sunny, but not direct sunlight position, keeping moist etc., all over again!   

  • Once seedlings are large enough to handle, you can transfer them into a pot, or I planted them into my flower bed last year inside the modular tray as I used a biodegradable one, so you can plant the whole plate, meaning no fiddly business trying to remove them.

If you do give it ago and plant your seeds, I would love to see so tag me or send me your photos. I will also share the process of my seeds over in our Facebook group or on Instagram stories too so we can compare and see how it goes together, can't wait to see what happens!
