Planting
When to Plant
- Ideal planting time is during the warm, wet season for best growth conditions.
How to Plant
- Select a well-draining location with plenty of sunlight.
- Prepare the soil by digging it deeply and enriching it with compost.
- Plant banana suckers (young shoots) or rhizomes directly into the soil, spacing them 8 to 10 feet apart.
- Water thoroughly after planting.
Growth Timeline
- Establishing 1 year
- First harvest possible years 1–2
Planting Calendar
- Plant outdoors: 2–4 weeks after the last frost
- Plant out: Apr 24 – May 14
Care
Care Calendar
- Mulch · Apr 10 – May 14
Apply organic mulch to conserve moisture, keeping it away from the stem. - Repot · Apr 10 – May 14
Move container-grown plants into a larger pot if roots have filled the old one. - Feed · Apr 24 – Oct 1
Feed regularly during active growth with a balanced fertilizer. - Prune · May 8 – Oct 1
Remove excess suckers during growth and cut down each stem after it fruits. - Protect · Oct 11 – Oct 31
Before frost, move potted plants indoors or insulate outdoor stems and roots.
Watering
- Maintain consistent moisture in the soil; water regularly, especially during dry spells.
Weeding
- Regularly check for weeds and remove them by hand or with mulch to prevent competition for nutrients.
Mulching
- Apply a thick layer of organic mulch (straw, leaves) around the base to retain moisture and suppress weeds.
Fertilizing
- Use a balanced fertilizer every couple of months, focusing on potassium, nitrogen, and phosphorus.
Thinning
- Remove excess suckers to promote healthy growth of the main plant, ideally leaving 3-4 main shoots.
Pest Management
- Monitor for pests like aphids and spider mites; use neem oil or insecticidal soap as organic pest management solutions.
Harvesting
- Bananas are typically harvested when green and firm, about 3-4 weeks before they ripen.
Growing in Containers
Grows well in a pot of at least 50 litres (13 US gallons), with drainage holes. Can be grown indoors as a houseplant.
Propagation
From suckers
- Choose a healthy sword sucker with narrow, upright leaves.
- Wait until it has several leaves and is about 2–3 feet tall.
- Cut down beside it with a sharp spade, keeping a piece of corm and some roots attached.
- Separate it from the parent plant.
- Replant at the same depth in moist, well-drained soil.
- Water thoroughly and keep the soil evenly moist while it establishes.
Companion Plants
Good neighbors
- Sweet potato: Its spreading vines can cover the soil beneath bananas, helping suppress weeds and retain moisture.
- Taro: Taro is commonly intercropped with bananas because it tolerates their partial shade and similarly moist conditions.
- Comfrey: Gardeners grow comfrey near bananas and cut its leaves for mulch around the banana plants.
