Why Don't Calla Lilies Bloom
Are you familiar with this? The knowledge about why calla lilies don't bloom in the field of green plants and flowers, please see the detailed introduction below.
Why Don't Calla Lilies Bloom
Calla lilies may fail to bloom if overwatered; they need to be placed in a well-ventilated area to accelerate the evaporation of excess water in the pot, and watering should be reduced during later maintenance. If blooming is affected by improper fertilization, the amount of fertilizer can be increased, but not just nitrogen fertilizer. Phosphorus and potassium fertilizers should be added before flowering. Insufficient lighting can also affect blooming, so they need to be moved to a well-lit area, but avoid direct sunlight.
Reasons Why Calla Lilies Don't Bloom
1. Overwatering: If calla lilies are overwatered, the roots may accumulate water, leading to root rot and poor growth in the underground parts, which can also affect normal blooming.
2. Insufficient nutrients: Calla lilies are fertilization-loving plants. If not fertilized promptly during growth or if excessive nitrogen fertilizer is applied, blooming will be impossible, and even if there are flower buds, they won't bloom normally.
3. Insufficient lighting: Calla lilies prefer a sunny environment and thrive in sunny locations. If they lack sunlight, the plants cannot perform photosynthesis, which will also affect normal blooming.
Methods to Deal with Non-Blooming Calla Lilies
1. If calla lilies don't bloom due to overwatering, stop watering and place the pot in a well-ventilated area to accelerate the evaporation of excess water in the pot, and reduce watering during later maintenance.
2. If improper fertilization affects blooming, increase the amount of fertilizer, but do not just add nitrogen fertilizer. Phosphorus and potassium fertilizers should be added before flowering to promote blooming.
3. If calla lilies don't bloom due to insufficient lighting, move them outside, ensuring they receive more than three hours of sunlight daily. During the flowering period, you can also extend the lighting time. Move them to a well-lit area, but avoid direct sunlight to prevent leaves and petals from getting burned.
Calla Lily Blooming Time
Calla lilies typically bloom between February and March each year. However, in tropical or subtropical climates, they do not go dormant throughout the year, and their natural flowering period can start from November and last until June of the following year. March and April are also their peak blooming period. Different varieties have different blooming periods, with the 'Silver Star' variety blooming from July to August.
