a well-known permaculture technique often used in banana circles (or banana pits). When you cut the main banana stalk after it fruits (it only fruits once), leaving the lower half in place and filling the hollowed center with nutrients provides a slow-releasing compost system for the new suckers (baby banana plants) that will emerge from the base.
Best Fertilizers to Use in the Hollowed Banana Stalk:
- Composted Manure (Cow, Chicken, or Horse)
- Amount: 1–2 shovelfuls (about 2–4 lbs)
- High in nitrogen and organic matter. A slow, natural feed.
- Banana Peels, Coffee Grounds, and Kitchen Scraps
- Amount: Fill up 1/2 to 3/4 of the hollow core over time
- These decompose and release potassium, nitrogen, and phosphorus.
- Organic Fertilizer Pellets (Slow Release)
- Type: 4-6-4 or 10-10-10 organic mix
- Amount: 1/4 to 1/2 cup in the hollow core
- Pellets are ideal here because they release nutrients over weeks.
- Granular Fertilizer (Balanced NPK like 8-10-8)
- Use if you want faster nutrient availability
- Amount: 1/4 cup, mix with compost or mulch to reduce burn risk
- Not as ideal as slow-release for this method unless diluted or layered.
- Wood Ash (Optional)
- Small handful (very little)
- Adds potassium but should be used sparingly to avoid high alkalinity.
Recommended Setup:
- Step 1: Cut the banana stalk to about 2–3 feet above ground.
- Step 2: Hollow out a portion of the center (just deep enough to hold material).
- Step 3: Layer in a mix of compost, slow-release pellets, and soft green material like banana leaves or peels.
- Step 4: Cover with mulch to retain moisture and aid breakdown.
Tips:
- Refill the hollow over time—like a compost bin.
- Avoid synthetic high-nitrogen fertilizers—they can burn the new pups.
Yes, incorporating inoculants like Hawaiian Bokashi Inoculant™ into your banana tree fertilization routine can be highly beneficial. This inoculant introduces beneficial microbes that accelerate the decomposition of organic matter, enhance nutrient availability, and improve soil health—particularly advantageous in Hawaii's tropical climate.
Benefits of Using Hawaiian Bokashi Inoculant™
- Accelerated Decomposition: The inoculant speeds up the breakdown of organic materials, enriching the soil more quickly.
- Enhanced Nutrient Availability: It increases the availability of essential nutrients like potassium and phosphorus, which are vital for banana plant growth.
- Improved Soil Health: By boosting microbial activity, it enhances soil structure and fertility, promoting healthier plant development.
How to Mix and Apply with Fertilizer
Materials Needed:
- Hawaiian Bokashi Inoculant™(Earth Trade)
- Organic materials (e.g., banana peels, coffee grounds, kitchen scraps)
- Optional: Composted manure or slow-release organic fertilizer pellets(ResearchGate)
Steps:
- Prepare the Banana Stalk: After harvesting, cut the banana stalk to about 2–3 feet above the ground and hollow out the center to create a cavity.
- Layer Organic Materials: Place a mix of organic materials into the hollowed stalk.
-
Apply Bokashi Inoculant: Sprinkle the Hawaiian Bokashi Inoculant™ over the organic materials.(HawaiianVolcanicOrg
anic ) - Optional Fertilizer Addition: If using, add composted manure or slow-release fertilizer pellets on top.
- Cover and Maintain: Seal the top with mulch to retain moisture and promote anaerobic fermentation.
- Monitor and Reapply: Check periodically and add more organic materials and inoculant as needed.
Additional Tips
- Moisture Control: Ensure the contents remain moist but not waterlogged to facilitate microbial activity.
- Avoid Overuse: While beneficial, excessive application of inoculant is unnecessary; follow the recommended amounts.
- Integration with Existing Practices: This method complements traditional fertilization techniques and can enhance their effectiveness.
