Reasons Why Bowl Lotus Fails to Bloom
The bowl lotus, an elegant representative of aquatic plants, has a non-blooming issue that troubles many gardening enthusiasts. This article will delve into the four key factors behind the non-blooming of bowl lotus and provide professional solutions to help you create a blooming water fairy.
Optimizing the Growing Environment for Bowl Lotus
Essentials for Container Space Upgrade
1. Root Development Principle: The bowl lotus absorbs nutrients through rhizome division, requiring a growth space of over 30cm in diameter for each plant. Insufficient root expansion can lead to hindered nutrient absorption.
2. Guide to Potting Practice: Choose a ceramic wide-mouth container, keep the original soil when transplanting to minimize root damage, and ensure the new pot's depth is over 25cm with a water layer of 5cm.
Core Strategies for Nutrient Management
Accurate Fertilization Plan
1. Analysis of Fertilization Needs: During the blooming period, bowl lotus requires a special ratio of nitrogen, phosphorus, and potassium (2:3:2). A phosphorus deficiency directly affects flower bud differentiation.
2. Tips for Using Organic Fertilizer: Mix fermented chicken manure and bone meal in a 3:1 ratio and apply 50g around the pot edge monthly, supplemented by foliar application of potassium dihydrogen phosphate solution.
Key Steps in Substrate Maintenance
Soil Replacement Cycle and Ratio
1. Characteristics of Substrate Aging: When the pH value is >7.5 or there is a hardening and whitening of the soil, it indicates the need to replace the pond mud.
2. New Soil Preparation Plan: Use a mixed substrate of river mud (70%) + decomposed leaf soil (20%) + vermiculite (10%), with the amount of base fertilizer controlled at 15% of the total weight.
Key Points of Ecological Regulation
Weed Control System
1. Competitive Mechanism Analysis: Algae and weeds consume dissolved oxygen in the water, lowering the water temperature by 2-3°C, indirectly affecting flower bud formation.
2. Biological Control Plan: Release 5-8 mosquito-eating fish to build an ecological chain, combined with weekly manual inspections and cleanups to maintain water purity.
By systematically optimizing the cultivation environment, providing precise nutrient supply, regularly updating the substrate, and maintaining ecology, along with more than 6 hours of adequate sunlight daily, it is usually possible to witness the bud germination within 90 days. It is recommended to use a water quality tester to monitor the pH value (6.5-7.0) and EC value (1.2-1.8mS/cm) for scientific and meticulous management.
