Balloon flowers (Platycodon grandiflorus) are top picks for gardeners who want stunning, low-maintenance blooms.
While these plants are easy to grow, they still need some basic care. Young balloon flowers might need more attention and watering, but all balloon flowers do well with regular watering and well-draining, slightly acidic soil.
Mulching and watering in the morning can help them absorb water better, helping them thrive for many years.
Origins and Growth
Balloon flowers originate from China and Japan but are not invasive in North America. They grow well in USDA zones 4 through 9.
It takes years for balloon flowers to mature if grown from seeds, but they can reach about 2 feet tall with good soil and enough sunlight.
Unlike many other perennials, they rarely need dividing, and they produce plenty of seeds for new plants with minimal effort.
Watering Balloon Flowers
Balloon flowers can be started from seeds or bought as young plants. Their seeds need constant moisture to germinate.
Young plants may need extra care and water at first, as they establish themselves. For healthy roots, water them deeply but infrequently, ensuring each plant gets at least 30 seconds of watering.
They like moist soil but can suffer from root rot, so make sure the soil drains well and check moisture levels an inch or two below the surface before watering.
They typically need about an inch of water per week, but factors like temperature, wind, and soil type can affect this.
Morning Watering and Mulch
Watering plants early in the morning is efficient, reducing water loss to evaporation. If balloon flowers look thirsty in the afternoon, water them right away instead of waiting for the next morning.
Mulch can help keep your plants hydrated and reduce your water bill. It also limits weeds and stabilizes soil temperature, which is especially helpful for balloon flowers that need consistently moist soil.
A 2 to 3-inch layer of mulch can make a big difference during dry periods, but be sure not to cover the plant crowns.
By following these simple tips, your balloon flowers will flourish and bring beauty to your garden for years to come.
