    Does anyone know how to promote growth in a very old Boxwood hedge? Some call it an English Hedge also.



    Todd, boxwoods are extremely slow-growing and yours may have maxed out in size, depending on the cultivar. If it’s “very old” and looking unwell it may just be done for. Aside from good soil, compost, sun, and water there’s not much else you can do. A light shearing will promote temporary new growth, but only on the surface. If you want something larger, there are other options out there for replacement.


    It still is very dense and healthy. I have composted and a little steer manure along the base for the last couple years. I have been smart about pruning it so the roots still get enough rain water.

    It has grown about 8 inches in height over 5 years, with some pruning on the top to keep things even.

    I guess that is all I can do.




    You might also try “plant growth activators.” McLendons should be able to help you with this as should West Seattle Nursery. Its fairly new technology and can give your boxwood a little “oomph!”
