Banana is a long game. From seed it takes 3-5 years before you see a harvest, which is why most growers start from a nursery plant. Container growing is entirely possible, but the container has to be sized for a plant that will live in it for years.
Short answer
Grow banana in a 60 litre container at least 50 cm deep, watering about 1500 ml per 10 litres of soil every day, and keep temperatures between 20 and 30 °C. First harvest comes 270–540 days after sowing.
Where to plant it
What size pot does banana need?
60 litres and 50 cm deep is the realistic minimum for a single plant. Pick a container below to see what changes.
| Container | Minimum size | Depth | Notes |
|---|---|---|---|
| Pot | 60 L | 50 cm | Requires very large pots with excellent drainage. Dwarf varieties are best for containers. |
| Grow bag | 60 L | 50 cm | Fabric bags promote air pruning and good drainage, but dry out faster. |
| Open ground | — | 60 cm | Requires rich, well-draining soil and ample space. Protect from strong winds. |
| Raised bed | 100 L | 60 cm | Excellent for controlling soil conditions and drainage. Ensure sufficient depth for root spread. |
Watering
How often should you water banana?
Every day through the growing season, at about 1500 ml per 10 litres of soil — daily in hot weather, every 2 days when it turns cool. Water in the early morning. Deep and consistent watering works best.
Too little water
- wilting leaves
- yellowing leaves
- stunted growth
- small fruits
Too much water
- yellow lower leaves
- soft stem base
- root rot
- stunted growth
Avoid: dry spells; standing water; shallow watering.
Climate
Can you grow banana where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 20 – 30 °C |
|---|---|
| Survives | 10 – 35 °C |
| Germinates above | 25 °C — best at 30 °C, about 90 days |
| Flowers drop | above 38 °C, or below 15 °C |
| Sunlight | 8–14 hrs/day, best 10 |
| Frost | Highly sensitive — will not survive it |
The flower-drop thresholds matter more than the survival ones. A plant can be perfectly alive at 35 °C and still give you nothing.

Common mistakes
Why banana fails, and how to avoid it
- A container that is too small
Below 60 litres the root run is too shallow. The plant grows, flowers late, and drops whatever it sets because it cannot support the crop.
- Watering too lightly
A daily splash wets the top few centimetres and nothing else. Banana wants about 1500 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Ignoring the flower-drop threshold
Above 38 °C, or below 15 °C, flowers fall before setting. The plant can look perfectly healthy and still give you nothing — shade it through the hottest hours.
- Harvesting too late
Left too long the colour changes, seeds harden and the flavour sharpens. Pick on the signs listed below, not on the calendar.
- Planting it beside Cabbage Family
Brassicas (cabbage, broccoli, kale) can inhibit the growth of banana plants due to allelopathic compounds or nutrient competition.
- Leaving it out through a cold snap
Banana is highly frost-sensitive. One night below 10 °C can end the plant outright — bring containers in or cover them.
Companions
What to plant with banana
Good neighbours
Nitrogen-fixing plants like beans and peas enrich the soil, benefiting the heavy-feeding banana.
A dynamic accumulator, comfrey draws up nutrients from deep in the soil and can be used as a nutrient-rich mulch.
Acts as a living ground cover, suppressing weeds and conserving soil moisture around the banana plant.
Its strong scent can deter some pests, and it helps to create a beneficial microclimate.
Tolerates partial shade from banana plants and thrives in similar moist, rich soil conditions.
Keep apart from
Brassicas (cabbage, broccoli, kale) can inhibit the growth of banana plants due to allelopathic compounds or nutrient competition.
Corn is a heavy feeder and will compete intensely with bananas for water and nutrients, especially nitrogen.
Potatoes are also heavy feeders and can compete with bananas for essential nutrients, potentially stunting growth.
Fennel is known to release compounds that inhibit the growth of many nearby plants, including bananas.
Large trees with extensive root systems will aggressively compete with bananas for water and nutrients, severely impacting their growth.
Problems
Banana pests and diseases
Each lists the weather that brings it on, so you know when to start checking rather than reacting once it's established.
Panama Disease humidity any · temp 20-30
Also known as Fusarium Wilt. Causes yellowing and wilting of leaves, starting from older ones. The pseudostem may split, and internal tissues show discoloration. Highly destructive.
Black Sigatoka humidity >90% · temp 25-30
Fungal leaf spot disease. Starts as tiny, reddish-brown streaks on leaves, evolving into large, black necrotic spots with yellow halos. Reduces photosynthetic area and fruit yield.
Banana Bunchy Top Virus humidity any · temp any
Viral disease transmitted by banana aphids. Causes stunted growth, dark green streaks on petioles, and leaves that are stiff, upright, and 'bunchy' at the top. Infected plants rarely produce fruit.
Banana Weevil humidity any · temp any
Adult weevils lay eggs in the corm (underground stem). Larvae tunnel through the corm, weakening the plant, causing it to fall over, and reducing yield. Look for holes at the base.
Nematodes humidity any · temp 20-30
Microscopic worms that attack banana roots, causing lesions, galls, and root rot. Leads to poor nutrient uptake, stunted growth, and increased susceptibility to other diseases.
Moko Disease humidity any · temp 25-35
Bacterial wilt disease. Causes rapid wilting and yellowing of leaves, often with a distinct yellow band at the margin. Fruits may rot internally, and a creamy bacterial ooze can be seen when the pseudostem is cut.
Cold Damage humidity any · temp <10
Bananas are tropical plants. Cold temperatures can cause leaves to turn yellow or black, growth to stop, and severe damage to fruit or even death of the plant.
Nutrient Deficiency Potassium humidity any · temp any
Potassium deficiency is common in bananas due to their high demand. Symptoms include yellowing of leaf margins, scorched leaf tips, and poor fruit development.
Harvest
When to harvest banana
First picking falls between day 270 and day 540, and the plant then keeps producing for about 14 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Fruits are plump and rounded, losing their angularity.
- The 'bell' (male flower) has dried and fallen off, or is very small.
- A few individual bananas on the bunch may start to show a slight yellow tinge.
How much to expect
Storing it: Hang the green bunch in a cool, dark, well-ventilated area to ripen. Once ripe, store at room temperature for a few days or refrigerate to slow further ripening (peel may blacken but fruit remains good).
Questions
Banana: common questions
How long does banana take to grow?
About 365 days from sowing to the first harvest, with picking usually starting between day 270 and day 540. It then keeps producing for roughly 14 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does banana need?
At least 60 litres and 50 cm deep for one plant. A raised bed wants 100 litres of soil and 60 cm of depth.
How often should I water banana?
About 1500 ml per 10 litres of soil, every day in normal weather — daily when it is hot and every 2 days when cool. Water in the early morning.
What temperature does banana need?
It does best between 20 °C and 30 °C and survives from 10 °C to 35 °C. Seed needs soil above 25 °C to germinate, ideally around 30 °C.
Can I grow banana in winter?
Not outdoors anywhere that frosts — it is highly frost-sensitive and will not survive it. In a frost-free winter it grows slowly; anywhere colder, treat it as a warm-season crop.
How do I know when banana is ready to harvest?
Fruits are plump and rounded, losing their angularity.; The 'bell' (male flower) has dried and fallen off, or is very small.; A few individual bananas on the bunch may start to show a slight yellow tinge.. Once picked: hang the green bunch in a cool, dark, well-ventilated area to ripen. once ripe, store at room temperature for a few days or refrigerate to slow further ripening (peel may blacken but fruit remains good).
How much does one banana plant produce?
Roughly 15 kg from a 20 litre container, or about 40 kg in open ground. Larger containers give proportionally more, up to a point.
