When do lotus flowers bloom
Walking by the lotus pond at dawn, watching the morning dew roll between the green leaves, and the pink and white petals unfold with the morning sun is the most poetic scene of summer. Many flower enthusiasts often encounter problems such as the flowering period not meeting expectations or the plants not blooming when cultivating lotus flowers. Today, we will start from the plant growth规律 (growth规律) and guide you to master the natural rhythm and key points of lotus flower care.
Analysis of the natural flowering period of lotus flowers
Standard flowering period and observation time
As a typical aquatic plant, the lotus follows a strict phenological rhythm. In the Yangtze River Valley, flower buds appear at the beginning of June, enter the peak flowering period from July to August, and a single flower can continue to bloom for 3-9 days. It is recommended to observe at 6-8 a.m., when the flowers are fully open and the fragrance is most intense.
Three variables affecting the flowering period
Different varieties have significant differences: the early-flowering variety of bowl lotus can bloom in late May, while large pond lotus may delay until July. The influence of regional climate is more obvious, with the Lingnan area blooming 15-20 days earlier than North China. Meteorological records in 2019 show that continuous high temperatures of 35℃ can advance the flowering period by 5-7 days.

Light enhancement measures
Lotus plants require 6 hours of direct sunlight per day, and planting in the shade or on the inner side of a balcony can easily lead to insufficient photosynthesis. Measures such as moving the pot orientation or pruning surrounding obstructions can be taken to ensure the plants receive adequate light.
Scientific fertilization strategy
It is recommended to use slow-release fertilizer with an N-P-K ratio of 5-10-10, and add 200-300 grams per cubic meter of water. Add phosphorus-potassium fertilizer solution when changing water, and be careful to avoid excessive nitrogen fertilizer, which can cause leafy growth.
Substrate improvement plan
Use a mixture of river mud and humus soil in a 3:1 ratio, maintaining a substrate thickness of 15-20 cm. New soil needs to be replaced every two years, and bone meal should be added regularly to supplement trace elements, avoiding soil compaction that affects root development.
By observing leaf color and the speed of flower bud formation, the care plan can be adjusted in a timely manner. Keeping the water temperature between 20-30℃ and managing the water level appropriately, you will surely harvest a pool full of clear lotus flowers. When the first lotus flower blooms, all the waiting and nurturing will turn into the most beautiful summer gift.
