If you want to get another round from your tulips, you'll want to remove them from their pots and transplant them into the soil after flowering. 'You can fertilise with a balanced, slow-release fertiliser to support the bulbs for the next year's growth,' says Christopher.
Remember: tulip bulbs tend to perform poorly if you keep them in pots for two years on the trot, so it's best to start fresh if you want pots filled with blooms again.
