Yes, you can transplant tulips outdoors after they've finished blooming indoors. Once the tulip flowers have faded and the foliage turns yellow, it indicates that the bulbs have stored enough energy for future growth. Carefully dig up the bulbs, not damaging them, and choose a suitable outdoor location. Plant the tulip bulbs in well-draining soil, ensuring they receive ample sunlight. Allow the foliage to wither completely before cutting it back, allowing the bulbs to replenish their nutrients for the next blooming season. Remember, following these guidelines on how to take care of tulips, whether indoors or in a vase, will help you enjoy their beauty for a longer duration. Proper watering, suitable environmental conditions, fertilisation, and timely transplanting will all contribute to the health and longevity of your tulips.
