Like most plants Lilacs will benefit from compost and humus worked into the soil, this helps maintain moisture during dry spells and provides additional nutrients. Regular fertilisation is not necessary. Use a general purpose fertilizer in early spring or alternatively one that is high in Phosphorus is the perfect choice. Food with a high nitrogen content should be avoided as this will have a negative effect on the flowers. This should only be repeated once more after the flowers have died back
