Mulberry is a long game. From seed it takes 5-10 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 mulberry in a 50 litre container at least 50 cm deep, watering about 1500 ml per 10 litres of soil every 4 days, and keep temperatures between 18 and 30 °C. First harvest comes 30–45 days after sowing.
Where to plant it
What size pot does mulberry need?
50 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 | 50 L | 50 cm | Requires a very large pot with excellent drainage. Best for dwarf varieties. |
| Grow bag | 75 L | 60 cm | Fabric bags promote air pruning and prevent root circling. Best for dwarf varieties. |
| Open ground | — | 100 cm | Mulberries thrive in the ground with ample space for root development. |
| Raised bed | 100 L | 80 cm | Ensure the raised bed is deep and wide enough to accommodate the tree's root system. |
Watering
How often should you water mulberry?
Every 4 days through the growing season, at about 1500 ml per 10 litres of soil — every 2 days in hot weather, every 7 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
Avoid: shallow frequent watering; standing water around trunk.
Climate
Can you grow mulberry where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 18 – 30 °C |
|---|---|
| Survives | -20 – 40 °C |
| Germinates above | 15 °C — best at 25 °C, about 20 days |
| Flowers drop | above 35 °C |
| Sunlight | 6–14 hrs/day, best 8 |
| Frost | Medium sensitivity |
The flower-drop thresholds matter more than the survival ones. A plant can be perfectly alive at 40 °C and still give you nothing.

Common mistakes
Why mulberry 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. Mulberry wants about 1500 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Ignoring the flower-drop threshold
Above 35 °C flowers fall before setting. The plant can look perfectly healthy and still give you nothing — shade it through the hottest hours.
- Planting it beside Black Walnut
Black walnut trees produce juglone, a chemical that is toxic to many plants, including mulberries, potentially stunting growth or causing decline.
Companions
What to plant with mulberry
Good neighbours
Acts as a dynamic accumulator, drawing up nutrients from deep in the soil and making them available to the mulberry tree when used as a chop-and-drop mulch.
Fixes nitrogen in the soil, improving fertility for the mulberry tree. Also acts as a living mulch, suppressing weeds and retaining soil moisture.
Roots release compounds that deter root-knot nematodes, and their strong scent can repel other harmful insects from the mulberry tree.
Can act as a trap crop for aphids, drawing them away from the mulberry tree. Also deters other pests and adds beauty to the understory.
Keep apart from
Black walnut trees produce juglone, a chemical that is toxic to many plants, including mulberries, potentially stunting growth or causing decline.
Other large, established trees (e.g., oak, maple) will intensely compete with mulberries for light, water, and soil nutrients, especially if planted too close.
Plants like raspberries and blackberries can become invasive, competing for resources and making access and harvesting of mulberries difficult due to their thorny nature.
Problems
Mulberry 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.
Leaf Spot humidity >70% · temp 20-30
Appears as small, dark spots, often with purple margins, on mulberry leaves. Severe infections can lead to premature defoliation and reduced vigor.
Powdery Mildew humidity 50-70% · temp 20-27
White, powdery patches develop on the surface of mulberry leaves, young shoots, and sometimes fruit. Can cause distortion and reduced photosynthesis.
Bacterial Blight humidity >80% · temp 10-20
Causes water-soaked spots on leaves, cankers on twigs, and dieback of young mulberry shoots, especially in cool, wet conditions.
Cankers humidity any · temp any
Sunken, discolored areas on mulberry branches or trunk, often oozing sap. Can girdle and kill branches, especially after pruning wounds.
Scale Insects humidity <60% · temp >25
Small, immobile, shell-like bumps on mulberry stems and leaves. They suck sap, causing yellowing, stunted growth, and sometimes sooty mold from honeydew.
Mealybugs humidity >60% · temp >20
White, cottony masses found in leaf axils and on the undersides of mulberry leaves. These sap-suckers weaken the plant and excrete sticky honeydew.
Japanese Beetles humidity any · temp >20
Adult beetles (metallic green head, copper wings) skeletonize mulberry leaves, leaving only the veins. Can cause significant defoliation.
Root Rot humidity any · temp any
Caused by overwatering or poor drainage, leading to yellowing leaves, wilting, stunted growth, and eventual death of the mulberry tree. Roots become soft and black.
Harvest
When to harvest mulberry
First picking falls between day 30 and day 45, and the plant then keeps producing for about 25 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Full color (black, red, or white depending on variety)
- Soft to the touch
- Easily detaches from the stem with a gentle tug
How much to expect
Storing it: Refrigerate fresh mulberries for 2-3 days. For longer storage, freeze them or process into jams, pies, or dried fruit.
Questions
Mulberry: common questions
How long does mulberry take to grow?
About 1095 days from sowing to the first harvest, with picking usually starting between day 30 and day 45. It then keeps producing for roughly 25 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does mulberry need?
At least 50 litres and 50 cm deep for one plant. A raised bed wants 100 litres of soil and 80 cm of depth.
How often should I water mulberry?
About 1500 ml per 10 litres of soil, every 4 days in normal weather — every 2 days when it is hot and every 7 days when cool. Water in the early morning.
What temperature does mulberry need?
It does best between 18 °C and 30 °C and survives from -20 °C to 40 °C. Seed needs soil above 15 °C to germinate, ideally around 25 °C.
Can I grow mulberry in winter?
It tolerates cold better than most, down to about -20 °C, so a sheltered spot or a cold frame will often carry it through.
How do I know when mulberry is ready to harvest?
Full color (black, red, or white depending on variety); Soft to the touch; Easily detaches from the stem with a gentle tug. Once picked: refrigerate fresh mulberries for 2-3 days. for longer storage, freeze them or process into jams, pies, or dried fruit.
How much does one mulberry plant produce?
Roughly 4 kg from a 20 litre container, or about 30 kg in open ground. Larger containers give proportionally more, up to a point.
