I would like to know what to do when Buxus hedge turns brown. Do we need to add something to the soil?
Buxus leaves turning brown often occurs during the winter months or when plants are seriously nutrient deficient. Unfortunately, there is no point applying fertiliser in winter months so you must be patient until the warmer weather arrives in mid-October. Fertilise your Buxus plants regularly with Daltons Premium Tree & Shrub Fertiliser through until mid-December. Recommence applications in the New Year (around mid-Feb), fertilising right through until mid-April.
Remember, Buxus plants can be considered a gross feeder (a plant that requires more fertiliser and nutrients to grow successfully) and therefore generous amounts of fertiliser should be applied. Make sure after any fertiliser application that you water it in well.
