distance between lavender plants for a low hedge

hello chaps
I'm planning a low hedge of white lavender to edge a lovely brick path. Currently there is nothing but damp grass there and I plan to dig it out, add plenty of well rotted manure (will that be ok for lavender?) and then plant with young lavender plants. I'd like a fairly dense low hedge and was wondering what distance I should plant them apart.
Many thanks

 

Hi Lynne,
Firstly is the type of Lavander you have in mind, fully hardy. Some white lavs aren't as hardy as their more well known purple forms.
Secondly, If you have damp grass, do you mean it is a bit boggy? Lavender needs a free draining soil. It hates it's feet to be continually wet for any length of time. You would have to put alot of drainage in a trench where you intend to plant the lavs.
Lavander has a variety of forms, some larger than others. If you have or know the lav in question, I'd measure the width, reduce by about a 1/4 and plant at that distance apart. Sorry I can't be more specific.

 

the path is going to be used to provide a walkway between two parts of my garden. On the one side it's boggy ground, and I plan to plant it up with appropriate stuff. The other side is fine, free draining, very fertile ground. It's this side where I want to grow the lavender. I had a chat with the nursery today and they suggested planting them at a foot apart.
I once planted some lemon scented lavender and they were dreadfully short lived - a couple of seasons and they all died off. Weird!

Thanks for the advice

 

You're welcome. re short lived, take cuttings this summer, to ensure enough plants to replace any losses. Good luck
