Hello everyone.
Hoping to get a little advice regarding spacing for Sweet Viburnum please.
We have a long fence line approx 90m and have previously planted Sweet
Viburnum to approx a quarter of this with spacing of 1m.
The plants are approx 400mm-500mm in height and planted about a year and a half ago.
We are looking at planting the remaining area and now have a better understanding of spacing and that 1.5-2m may have been a more suited distance for the growth and health of the plant.
•Would please love some guidance on what distance you would recommend between future plantings? (We are hoping to have them at full height which is advised at 3-5m and 2-4m wide.
Also,
• In your opinion will our previously planted Viburnum be ok with the smaller spacing of 1M or when they develop will this hinder their health and growth?
We are wondering if we go to the effort of transplanting them to a greater distance between now to achieve a better future outcome or if we just leave them & I’m worrying over nothing?
We are also aware of the potential risks associated with moving plants and what would be the better option for our existing plants.
Thank you all so very much. We are rather new to gardening and everything we looked up on the internet gave mixed advice.

When planting shrubs as a hedge the general rule is a ratio of height to spacing of 3:1. This will depend on the natural width of plant, and how dense you want the hedge to be. If you want the final height to be 5m then you are looking a spacing of 1.6 m apart you could possibly go to 2m apart give the width of the Viburnum. Personally, I would not be removing any of the plants that are already there as you are a likely to disturb/damage the roots of the ones you are wanting to save.
