Plum is a long game. From seed it takes 3-6 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 plum 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 18 and 28 °C. First harvest comes 90–150 days after sowing.
Where to plant it
What size pot does plum 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 very large pot for dwarf varieties, regular watering is crucial. |
| Grow bag | 50 L | 45 cm | Fabric bags provide good aeration, but tend to dry out faster. |
| Open ground | — | 60 cm | Ideal for full-sized trees, allows for deep root development and stability. |
| Raised bed | 100 L | 60 cm | Good drainage and allows for specific soil mixes, suitable for dwarf varieties. |
Watering
How often should you water plum?
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. Drip irrigation or slow deep watering works best.
Too little water
- wilting leaves
- premature fruit drop
- stunted growth
Too much water
- yellowing leaves
- root rot
- poor growth
Avoid: shallow frequent watering; waterlogging.
Climate
Can you grow plum where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 18 – 28 °C |
|---|---|
| Survives | -25 – 35 °C |
| Germinates above | 10 °C — best at 20 °C, about 21 days |
| Flowers drop | above 30 °C, or below -2 °C |
| Sunlight | 6–12 hrs/day, best 8 |
| Frost | Medium sensitivity |
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 plum 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. Plum 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 -2 °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 Walnut
Releases juglone, a chemical highly toxic to plum trees and other members of the rose family, causing stunted growth and eventual death.
Companions
What to plant with plum
Good neighbours
Accumulates nutrients from deep in the soil, making them available to the plum tree. Attracts pollinators and can be used as a nutrient-rich mulch.
Acts as a trap crop for aphids, diverting them from the plum tree. Also deters borers and other pests.
Breaks up compacted soil with its deep taproot, improving aeration and water penetration. Brings up nutrients from deeper soil layers.
Emits a strong scent that deters aphids, spider mites, and other common pests from the plum tree.
Fixes nitrogen in the soil, enriching it for the plum tree. Acts as a living mulch, suppressing weeds and retaining soil moisture.
Keep apart from
Releases juglone, a chemical highly toxic to plum trees and other members of the rose family, causing stunted growth and eventual death.
Produces substances from its roots that inhibit the growth of plum trees and many other fruit trees.
Can compete heavily for water and nutrients, and may harbor diseases like Verticillium wilt that can affect plum trees.
Birch trees are aggressive growers with shallow, widespread root systems that compete intensely with plum trees for water and nutrients.
Problems
Plum 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.
Plum Curculio humidity any · temp >18
Small, dark beetles that lay eggs in developing fruit, leaving crescent-shaped scars. Larvae tunnel into the fruit, causing premature drop.
Aphids humidity any · temp 15-25
Small, soft-bodied insects that cluster on new growth and the undersides of leaves, sucking sap and secreting sticky honeydew. Can cause leaf curl and stunted growth.
Brown Rot humidity >80% · temp 15-25
Fungal disease causing blossoms to turn brown and die, cankers on twigs, and brown, soft spots on ripening fruit that quickly spread and develop gray spores.
Black Knot humidity >70% · temp 10-25
Fungal disease characterized by hard, black, warty growths (knots) on twigs and branches. Can girdle branches and kill them.
Bacterial Canker humidity any · temp cool, wet
Causes sunken cankers on branches and trunks, often with gumming (amber-colored sap oozing). Can lead to dieback of branches and buds.
Shot Hole Disease humidity >70% · temp 10-25
Fungal disease causing small, reddish-purple spots on leaves that later turn brown and fall out, leaving a 'shot-hole' appearance. Can also affect fruit and twigs.
Powdery Mildew humidity 50-70% · temp 20-27
White, powdery fungal growth on leaves, shoots, and sometimes fruit. Can distort new growth and reduce fruit quality.
Scale Insects humidity any · temp any
Small, immobile insects that attach to branches and twigs, feeding on sap. Appear as small bumps. Can cause yellowing leaves, stunted growth, and sooty mold from honeydew.
Gummosis humidity any · temp any
Excessive oozing of amber-colored gum from the trunk or branches. Often a symptom of stress, injury, or disease (like bacterial canker or borers).
Plum Pox Virus humidity any · temp any
Also known as Sharka disease. Causes yellow ringspots or line patterns on leaves and fruit. Fruit may be deformed, ripen unevenly, and drop prematurely. No cure, infected trees must be removed.
Harvest
When to harvest plum
First picking falls between day 90 and day 150, and the plant then keeps producing for about 21 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Full color for the variety
- Slightly soft to the touch
- Easily detaches from the branch with a gentle twist
How much to expect
Storing it: Store at room temperature for a few days until fully ripe, then refrigerate for up to 1-2 weeks. Can be frozen or canned.
Questions
Plum: common questions
How long does plum take to grow?
About 120 days from sowing to the first harvest, with picking usually starting between day 90 and day 150. It then keeps producing for roughly 21 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does plum 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 plum?
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.
Why is my plum flowering but not fruiting?
Almost always pollination. Plum carries separate male and female flowers and needs pollen moved between them — without insects, nothing sets. Hand-pollinate in the morning with a male flower brushed against the centre of a female one.
What temperature does plum need?
It does best between 18 °C and 28 °C and survives from -25 °C to 35 °C. Seed needs soil above 10 °C to germinate, ideally around 20 °C.
Can I grow plum in winter?
It tolerates cold better than most, down to about -25 °C, so a sheltered spot or a cold frame will often carry it through.
How do I know when plum is ready to harvest?
Full color for the variety; Slightly soft to the touch; Easily detaches from the branch with a gentle twist. Once picked: store at room temperature for a few days until fully ripe, then refrigerate for up to 1-2 weeks. can be frozen or canned.
