Lavender Advice

I’ve had great success this year growing English lavender from seed. I grew nearly 40 plants to do exactly as you’re  looking to do. I have planted them out of modules into small pots to harden off the plants, I have since sowed more seeds but these are struggling I think there is a certain time frame in which they germinate. I know the seeds were in the modules in the poly tunnel for weeks before they started showing, but the 2nd lot germinated in about 2 weeks.
