Currant 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 currant in a 20 litre container at least 35 cm deep, watering about 1000 ml per 10 litres of soil every 3 days, and keep temperatures between 15 and 24 °C. First harvest comes 70–90 days after sowing.
Where to plant it
What size pot does currant need?
20 litres and 35 cm deep is the realistic minimum for a single plant. Pick a container below to see what changes.
| Container | Minimum size | Depth | Notes |
|---|---|---|---|
| Pot | 20 L | 35 cm | Ensure good drainage and adequate size for root development. |
| Grow bag | 20 L | 35 cm | Fabric bags provide good aeration and drainage, but may require more frequent watering. |
| Open ground | — | 40 cm | Plant in well-drained soil with good organic matter. Space plants adequately. |
| Raised bed | 40 L | 40 cm | Raised beds offer excellent drainage and control over soil composition. Ensure sufficient depth. |
Watering
How often should you water currant?
Every 3 days through the growing season, at about 1000 ml per 10 litres of soil — daily in hot weather, every 5 days when it turns cool. Water in the early morning. Drip irrigation or deep watering at base works best.
Too little water
- wilting leaves
- stunted growth
- small fruits
Too much water
- yellowing leaves
- root rot
- stunted growth
Avoid: water on leaves; standing water; letting soil dry out completely during fruiting.
Climate
Can you grow currant where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 15 – 24 °C |
|---|---|
| Survives | -30 – 30 °C |
| Germinates above | 10 °C — best at 18 °C, about 60 days |
| Flowers drop | above 28 °C, or below -5 °C |
| Sunlight | 6–10 hrs/day, best 8 |
| Frost | Low sensitivity |
The flower-drop thresholds matter more than the survival ones. A plant can be perfectly alive at 30 °C and still give you nothing.

Common mistakes
Why currant fails, and how to avoid it
- A container that is too small
Below 20 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. Currant wants about 1000 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Wetting the leaves
Overhead watering in the evening leaves foliage damp overnight, which is exactly the condition fungal disease needs. Water the soil, early in the day.
- Ignoring the flower-drop threshold
Above 28 °C, or below -5 °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 White Pine
Currants are an alternate host for White Pine Blister Rust, a fungal disease that is deadly to white pines. Planting them together can spread the disease.
Companions
What to plant with currant
Good neighbours
Emits a strong scent that deters aphids, spider mites, and other common pests.
Roots produce a chemical that kills root-knot nematodes, and flowers repel other harmful insects.
A dynamic accumulator, it draws up nutrients from deep in the soil, making them available to currants when used as a chop-and-drop mulch.
Repels Japanese beetles, ants, and flies, which can be problematic for currant bushes.
Acts as a living ground cover, suppressing weeds and helping to retain soil moisture around the currant bushes.
Keep apart from
Currants are an alternate host for White Pine Blister Rust, a fungal disease that is deadly to white pines. Planting them together can spread the disease.
Produces substances from its roots that inhibit the growth of many other plants, including currants.
Can share some diseases and pests, and compete for nutrients, potentially stunting currant growth.
Similar to potatoes, tomatoes can share diseases and pests, and compete for resources, negatively impacting currant health.
Members of the brassica family can inhibit the growth of many other plants due to allelopathic compounds or intense nutrient competition.
Problems
Currant 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.
White Pine Blister Rust humidity >90% · temp 10-20
Appears as yellow-orange spots on currant leaves. While not usually fatal to currants, it can severely damage nearby white pines. Remove infected leaves.
Powdery Mildew humidity 50-70% · temp 20-27
White, powdery patches on leaves, young shoots, and sometimes fruit. Can cause distortion and reduced vigor. Ensure good air circulation.
Anthracnose humidity >80% · temp 18-24
Small, dark spots with purple margins on leaves, stems, and fruit. Can lead to premature leaf drop and reduced yield. Prune infected parts.
Currant Aphids humidity any · temp 15-25
Small, soft-bodied insects that cluster on new growth and undersides of leaves, causing leaves to curl, distort, and turn reddish. Wash off with strong water spray.
Currant Borer humidity any · temp any
Larvae tunnel into the pith of stems, causing individual canes to wilt, yellow, and die back. Prune out and destroy affected canes below the entry hole.
Gooseberry Sawfly humidity any · temp 15-25
Larvae rapidly defoliate plants, often starting from the center of the bush. Inspect regularly and hand-pick or use organic insecticides.
Spider Mites humidity <50% · temp >27
Tiny pests that cause leaves to look stippled, pale, and eventually turn yellow and drop. Fine webbing may be visible on undersides of leaves. Spray with insecticidal soap.
Leaf Spot humidity >70% · temp 18-28
Various fungal diseases causing small, dark spots on leaves, often leading to yellowing and premature defoliation. Improve air circulation and remove fallen leaves.
Botrytis Gray Mold humidity >85% · temp 15-25
A fuzzy gray mold that can affect flowers and ripening fruit, especially in wet, humid conditions. Remove infected parts and ensure good air flow.
Harvest
When to harvest currant
First picking falls between day 70 and day 90, and the plant then keeps producing for about 20 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Berries are fully colored (red, black, or white depending on variety)
- Berries are plump and firm
- Easily detach from the stem with a gentle tug
- Taste test for desired sweetness
How much to expect
Storing it: Refrigerate unwashed berries in a shallow container for 1-2 weeks, or freeze for up to 6-12 months.
Questions
Currant: common questions
How long does currant take to grow?
About 365 days from sowing to the first harvest, with picking usually starting between day 70 and day 90. It then keeps producing for roughly 20 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does currant need?
At least 20 litres and 35 cm deep for one plant. A raised bed wants 40 litres of soil and 40 cm of depth.
How often should I water currant?
About 1000 ml per 10 litres of soil, every 3 days in normal weather — daily when it is hot and every 5 days when cool. Water in the early morning.
What temperature does currant need?
It does best between 15 °C and 24 °C and survives from -30 °C to 30 °C. Seed needs soil above 10 °C to germinate, ideally around 18 °C.
Can I grow currant in winter?
It tolerates cold better than most, down to about -30 °C, so a sheltered spot or a cold frame will often carry it through.
How do I know when currant is ready to harvest?
Berries are fully colored (red, black, or white depending on variety); Berries are plump and firm; Easily detach from the stem with a gentle tug; Taste test for desired sweetness. Once picked: refrigerate unwashed berries in a shallow container for 1-2 weeks, or freeze for up to 6-12 months.
How much does one currant plant produce?
Roughly 3 kg from a 20 litre container, or about 7 kg in open ground. Larger containers give proportionally more, up to a point.
