Yes, tulips can benefit from regular fertilisation. During their active growth phase, typically in spring, it's advisable to fertilise tulips with a balanced, water-soluble fertiliser once a month. Follow the instructions on the fertiliser package for the appropriate application method and dosage. Fertilising tulips provide essential nutrients that promote healthy growth and vibrant blooms. Remember to discontinue fertilisation once the foliage starts to wither, as the bulbs enter their dormant phase.
