Loquat 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 loquat in a 50 litre container at least 45 cm deep, watering about 1000 ml per 10 litres of soil every 7 days, and keep temperatures between 15 and 25 °C.
Where to plant it
What size pot does loquat need?
50 litres and 45 cm deep is the realistic minimum for a single plant. Pick a container below to see what changes.
| Container | Minimum size | Depth | Notes |
|---|---|---|---|
| Pot | 50 L | 45 cm | Requires large pot with excellent drainage. Repot as it grows. |
| Grow bag | 50 L | 45 cm | Fabric bags promote air pruning and good drainage. |
| Open ground | — | 90 cm | Requires well-drained soil and ample space for root development. |
| Raised bed | 100 L | 60 cm | Ensure sufficient depth for root system. Good for drainage. |
Watering
How often should you water loquat?
Every 7 days through the growing season, at about 1000 ml per 10 litres of soil — every 3 days in hot weather, every 14 days when it turns cool. Water in the early morning. Deep root watering works best.
Too little water
- wilting leaves
- leaf scorch
- fruit drop
- stunted growth
Too much water
- yellowing leaves
- leaf drop
- root rot
- stunted growth
Avoid: shallow frequent watering; standing water around trunk.
Climate
Can you grow loquat where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 15 – 25 °C |
|---|---|
| Survives | -10 – 35 °C |
| Germinates above | 15 °C — best at 20 °C, about 60 days |
| Flowers drop | above 30 °C, or below -3 °C |
| Sunlight | 6–12 hrs/day, best 8 |
| 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 loquat fails, and how to avoid it
- A container that is too small
Below 50 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. Loquat wants about 1000 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Ignoring the flower-drop threshold
Above 30 °C, or below -3 °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 Walnut
Releases juglone, a chemical highly toxic to many plants, including loquats, causing wilting and eventual death.
- Leaving it out through a cold snap
Loquat 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 loquat
Good neighbours
Roots produce a chemical that kills root-knot nematodes, which can affect loquat trees, and flowers repel other harmful insects.
Acts as a dynamic accumulator, drawing up nutrients from deep in the soil and making them available to the loquat tree when used as mulch.
Fixes nitrogen in the soil, enriching it for the loquat tree, and acts as a living mulch to suppress weeds and retain moisture.
Can act as a trap crop for aphids, diverting them from the loquat tree, and its flowers attract beneficial pollinators.
Its strong scent can deter various pests that might affect loquat trees, and it attracts beneficial insects.
Keep apart from
Releases juglone, a chemical highly toxic to many plants, including loquats, causing wilting and eventual death.
Produces substances from its roots that can inhibit the growth of many nearby plants, including fruit trees like loquat.
Highly competitive for water and nutrients, and its allelopathic compounds can inhibit the growth of other plants nearby.
Problems
Loquat 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.
Fire Blight humidity >70% · temp 18-29
A bacterial disease causing blossoms, shoots, and young fruit to blacken and shrivel as if scorched by fire. Can spread rapidly in warm, humid conditions.
Loquat Scab humidity >80% · temp 10-20
A fungal disease appearing as dark, velvety spots on leaves, twigs, and fruit. On fruit, spots become raised and corky, affecting appearance and quality.
Aphids humidity any · temp 15-25
Small, soft-bodied insects clustering on new growth and undersides of leaves, sucking sap and causing distorted leaves. May excrete sticky honeydew.
Fruit Flies humidity >60% · temp 20-30
Females lay eggs in ripening fruit, leading to maggots inside and premature fruit drop. Causes significant crop loss, especially in warm climates.
Scale Insects humidity any · temp any
Small, immobile pests that attach to stems and leaves, sucking sap. Appear as bumps or waxy coverings. Can cause yellowing, stunted growth, and defoliation.
Powdery Mildew humidity 50-70% · temp 20-27
White, powdery patches appear mainly on the upper surface of leaves, especially new growth. Can stunt growth and reduce fruit quality if severe.
Root Rot humidity any · temp any
Caused by waterlogged soil and poor drainage, leading to root decay, yellowing leaves, wilting, and eventual plant death. Ensure well-draining soil.
Chlorosis humidity any · temp any
Leaves turn yellow while veins remain green, especially on new growth. Often indicates iron deficiency due to high soil pH or poor nutrient uptake.
Harvest
When to harvest loquat
First picking falls between day 90 and day 120, and the plant then keeps producing for about 45 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Skin turns yellow to orange
- Fruit softens slightly
- Easily detaches from stem
- Sweet aroma
How much to expect
Storing it: Room temperature for a few days, or refrigerate for up to 2 weeks.
Questions
Loquat: common questions
What size pot does loquat need?
At least 50 litres and 45 cm deep for one plant. A raised bed wants 100 litres of soil and 60 cm of depth.
How often should I water loquat?
About 1000 ml per 10 litres of soil, every 7 days in normal weather — every 3 days when it is hot and every 14 days when cool. Water in the early morning.
What temperature does loquat need?
It does best between 15 °C and 25 °C and survives from -10 °C to 35 °C. Seed needs soil above 15 °C to germinate, ideally around 20 °C.
Can I grow loquat 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 loquat is ready to harvest?
Skin turns yellow to orange; Fruit softens slightly; Easily detaches from stem; Sweet aroma. Once picked: room temperature for a few days, or refrigerate for up to 2 weeks.
How much does one loquat plant produce?
Roughly 4 kg from a 20 litre container, or about 25 kg in open ground. Larger containers give proportionally more, up to a point.
