The best month to plant Oriental Lily bulbs depends on the climate and growing conditions in your area. Generally, it is recommended to plant lily bulbs in the fall, between September and November, when soil temperatures are cool and the bulbs can establish roots before the winter freeze.
But another great option to plant your Oriental Lily bulbs is in the spring, as soon as the ground is workable. Although your lilies will blooms this summer, be aware that they may not have enough time to establish roots before the summer heat and they wonβt grow to their full potential. It's important to avoid planting lily bulbs during periods of extreme heat or drought, as this can stress the plants and reduce their chances of survival.
Overall, the key is to choose a time when the soil is cool and moist, but not waterlogged, and to plant the bulbs at a depth of three times their diameter, with the pointed end facing up. With proper planting and care, Oriental lilies can thrive and produce beautiful blooms in the summer months.
