Planting a lavender hedge
I have planted a section of lavender hedging with 5 litre hidcote plants. I now need to plant the second section but am struggling to find the right size plants to match. I can find 5l hidcotes but instead of a single plug they are made up of 3 plugs growing together. Is this a good option and equivalent to a single 5l or is it better to just buy smaller individual plants and wait for them to catch up with the first section? Help please!
