How to Use Banana Peels as Flower Fertilizer
In the practice of home gardening, using kitchen waste to make organic fertilizers can reduce waste and cultivate healthy plants. Banana peels are rich in trace elements such as potassium, phosphorus, and calcium, which can be converted into natural flower fertilizers after scientific treatment, especially suitable for flowering plants like roses and orchids. This article systematically introduces three methods for making banana peel fertilizers to help you achieve the dual benefits of environmental protection and gardening.
Process of Making Banana Peel Fermented Liquid Fertilizer
Raw Material Preprocessing Stage
When collecting banana peels after eating, it is important to retain the fruit stem area, which contains a higher concentration of plant growth hormones. It is recommended to limit the weekly collection to 500g to avoid excessive fermentation that may produce odors. The cutting process is recommended to use a ceramic knife, as a metal knife may cause oxidation reactions that affect the efficacy of the fertilizer.
Fermentation Process Control
Use a wide-mouth glass container to fill the chopped peels to 3/5 of the volume, and adding rice washing water can accelerate the fermentation process. Adding orange peels can effectively neutralize odors; it is recommended to pair every 500g of banana peels with 2 pieces of citrus peel. Place it on an east-facing windowsill to receive morning sunlight during spring and summer, and it can be fermented in 15 days at a temperature of 25°C.
Technique for Preparing Banana Peel Dry Fertilizer
Dehydration Treatment Plan
The microwave drying method requires setting the medium fire mode for fractional heating, with each treatment not exceeding 200g. The natural drying method suggests using a bamboo winnowing tray and placing it in a well-ventilated area to dry for 3-5 days, avoiding direct sunlight to prevent nutrient loss. Dried banana peels can be ground into 0.5mm particles with a food processor for easy mixing into the growing medium.
Application Method Analysis
For potted plants, follow the layering principle: spread 5g of dry fertilizer powder at the bottom of a 20cm diameter pot, mix the middle layer with the matrix, and cover the top with 2cm of plain soil. For ground planted shrubs, apply 20g in a circular trench around each plant, and combining it with loosening the soil can enhance the persistence of the fertilizer effect.
Building a Banana Peel Composting System
The sandwich composting method suggests layering according to the ratio of banana peels: withered leaves: garden soil = 1:2:3. Spray EM bacteria solution every 10cm layer to accelerate decomposition, and cover the top with a 5cm thick layer of coconut coir to keep it warm and moist. Using a foam box container in winter can maintain the compost pile's temperature, and regularly opening the lid and stirring ensures the activity of aerobic bacteria.
By systematically processing banana peel fertilizers, it can not only improve the soil structure but also significantly enhance plant disease resistance. It is recommended to adjust the application frequency according to the plant growth cycle: apply liquid fertilizer every half month during the growing period, supplement dry fertilizer before flowering, and use compost to improve the matrix when repotting. Persisting in the utilization of kitchen waste resources can make gardening care more environmentally friendly and efficient.
