It got cooler the day before yesterday, and the lilies planted in autumn just started to sprout flower buds, but they got frostbitten. So, the question arises, how should we deal with them now?
How to care for lilies planted in autumn during winter?
Lilies are actually most suitable for planting in spring. With modern refrigeration technology, lilies can be induced to sprout, and ornamental lilies are also planted in autumn. Usually, they are planted after the beginning of autumn and can bloom in winter. However, the growth state of lilies varies greatly in different regions, and winter management is also different.
1. Southern warm regionsIn the southern regions, it is very warm in winter, and the lilies planted there can bloom normally with flower buds without worrying about frostbite.
However, for lilies planted in autumn that want to rebloom in spring, vernalization is needed after flowering. Since there is no dormancy period in winter, the growth time of the lily bulbs is relatively short. Therefore, when planting lilies in the southern region, it is necessary to frequently apply phosphorus and potassium fertilizers after sprouting to maintain sufficient nutrients and avoid excessive consumption of the bulbs by flowering.
When the flower buds show color, it's best to cut them down for arrangement in a vase, leaving a bit of stem and leaves, apply phosphorus and potassium fertilizers for about two weeks, and then dig up the bulbs.
Dig up the bulbs, remove the soil, and then soak them in an 800-fold solution of carbendazim for 30 minutes. After taking them out and drying the surface moisture, put them in a plastic bag with some slightly moist peat soil, and store them in the refrigerator for vernalization, usually for 35 days to complete the process.
After vernalization, they can be replanted to bloom again in spring. In the southern regions, not only do the lilies planted in autumn need to be vernalized after flowering, but the ones planted in spring also need to be refrigerated to rebloom.
2. Frost regionsIn regions with frost, if the lilies have already withered in winter, no special treatment is needed, because when the weather gets cold, the stems of the lilies will naturally wither, and the bulbs can naturally vernalize in winter and will sprout and bloom again in spring.
However, if the temperature has dropped to below 5 degrees Celsius in winter and the lilies are still in the state of growing flower buds, the potted lilies must be moved indoors and placed on a south-facing balcony for care. If the lilies are planted in the ground, they can be covered with insulating cloth or old clothes at night to protect them. If the temperature does not drop quickly, there is still a chance to bloom.
If the flower buds are very small, it will be difficult to survive until blooming, so it's better to let them wither naturally. After withering, they will enter winter dormancy, experience low temperatures in spring, and can bloom again in the new season.
Lilies cared for indoors in winter should be placed outdoors after flowering to let the bulbs freeze and complete vernalization. If they are kept in a warm room all the time and cannot vernalize, they will not be able to rebloom in spring.
Lilies are very easy to plant and rebloom. The key to reblooming is sufficient nutrients in the bulbs plus low-temperature vernalization. Therefore, it is recommended to keep the lilies planted in autumn well-fed and watered to maintain sufficient nutrients in the bulbs. With low-temperature vernalization, they can bloom in both spring and autumn.
