I have a large Lelandaii hedge (my neighbours) running down the length on my front garden. My frontage is approx 80ft long and is gravelled as we use it for parking. My question is 'What can I plant under the hedge to fill the large expanse of space between the ground and the bottom of the trees' I did buy 144 lavender plants to put in, now some body has told me that they wont grow there. HELP Tmj

The leylandii will take moisture and nutrients from the soil, so plants have to struggle. If you have bought lavender then try some at different distances as an experiment. The others you can plant elsewhere, to be moved in next year if the trials survive. If your ground is to the south of the hedge the new plants will get proper light.

Thank-you for your reply I will certainly try the trial. I do have somewhere else I can put the rest of the lavenders. The area under the leylandaii does get a lot of sun on my side so fingers crossed.
