Viola keeps producing once it starts. First picking comes around day 60, and the plant then crops for roughly 90 more days — but only if you keep picking. Blooms left on the plant is a signal to stop making more.
Short answer
Grow viola in a 2 litre container at least 15 cm deep, watering about 500 ml per 10 litres of soil every 2 days, and keep temperatures between 10 and 18 °C. First harvest comes 60–75 days after sowing.
Where to plant it
What size pot does viola need?
2 litres and 15 cm deep is the realistic minimum for a single plant. Pick a container below to see what changes.
| Container | Minimum size | Depth | Notes |
|---|---|---|---|
| Pot | 2 L | 15 cm | Good drainage is essential. |
| Grow bag | 3 L | 15 cm | Fabric bags provide good aeration. |
| Open ground | — | 15 cm | Ensure well-drained soil. |
| Raised bed | 5 L | 20 cm | Excellent for soil control and drainage. |
Watering
How often should you water viola?
Every 2 days through the growing season, at about 500 ml per 10 litres of soil — daily in hot weather, every 3 days when it turns cool. Water in the early morning. Bottom watering or at soil level works best.
Too little water
- wilting leaves
- stunted growth
- fewer flowers
Too much water
- yellowing leaves
- soft stems
- root rot
Avoid: overhead watering (can cause fungal issues); soggy soil.
Climate
Can you grow viola where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 10 – 18 °C |
|---|---|
| Survives | -5 – 25 °C |
| Germinates above | 15 °C — best at 18 °C, about 10 days |
| Flowers drop | above 25 °C |
| Sunlight | 4–8 hrs/day, best 6 |
| Frost | Low sensitivity |
The flower-drop thresholds matter more than the survival ones. A plant can be perfectly alive at 25 °C and still give you nothing.

Common mistakes
Why viola fails, and how to avoid it
- A container that is too small
Below 2 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. Viola wants about 500 ml per 10 litres of soil — one deep soak beats three shallow ones.
- Ignoring the flower-drop threshold
Above 25 °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 Tall Vigorous Plants
Plants that grow very tall and dense (e.g., sunflowers, corn) can heavily shade out violas, inhibiting their growth and flowering.
Companions
What to plant with viola
Good neighbours
Violas act as a living mulch, suppressing weeds, keeping the soil cool and moist, and adding a charming underplanting.
Violas provide continuous color and ground cover before and after spring bulbs (like tulips and daffodils) bloom, hiding fading foliage.
Violas help keep the soil cool and moist for cool-season vegetables like lettuce, potentially extending their harvest.
Pansies and violas are closely related and thrive in similar conditions, making them excellent companions for a vibrant display.
Keep apart from
Plants that grow very tall and dense (e.g., sunflowers, corn) can heavily shade out violas, inhibiting their growth and flowering.
Violas prefer consistently moist soil, which is incompatible with plants that require very dry conditions, leading to watering conflicts.
Problems
Viola 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.
Aphids humidity any · temp 15-25
Small, soft-bodied insects that cluster on new growth and the undersides of leaves, sucking sap and causing distorted growth. Can transmit viruses.
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 the undersides of leaves.
Slugs Snails humidity >80% · temp 10-20
Leave irregular holes in leaves and flowers, often with a silvery slime trail. Most active in cool, moist conditions, especially at night.
Powdery Mildew humidity 50-70% · temp 20-27
White, powdery fungal spots appear mainly on the upper surface of leaves. Causes leaves to yellow and die off prematurely, reducing vigor.
Downy Mildew humidity >80% · temp 10-20
Causes purplish-brown spots on the undersides of leaves, often with yellowing on the upper surface. Can lead to leaf distortion and death.
Leaf Spot Fungus humidity >70% · temp 18-28
Various fungi cause small, circular to irregular dark spots on leaves, sometimes with a yellow halo. Severe infections can lead to defoliation.
Root Rot humidity any · temp any
Caused by overwatering or poor drainage, leading to wilting, yellowing leaves, and a soft, mushy stem base. Roots appear dark and soft.
Pansy Scab humidity >75% · temp 15-25
Small, raised, scab-like lesions appear on leaves, stems, and flowers. Can cause distortion and reduce aesthetic value.
Botrytis Blight humidity >85% · temp 10-20
Also known as gray mold. Causes fuzzy gray fungal growth on flowers, buds, and leaves, leading to rot. Prevalent in cool, wet, poorly ventilated conditions.
Pansy Yellows humidity any · temp any
A phytoplasma disease spread by leafhoppers. Causes stunted growth, yellowing of leaves, and distorted, often greenish flowers. Infected plants rarely recover.
Harvest
When to harvest viola
First picking falls between day 60 and day 75, and the plant then keeps producing for about 90 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Fully open, vibrant flowers
How much to expect
Storing it: Use fresh immediately or store in a sealed container in the refrigerator for a few days.
Questions
Viola: common questions
How long does viola take to grow?
About 60 days from sowing to the first harvest, with picking usually starting between day 60 and day 75. It then keeps producing for roughly 90 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does viola need?
At least 2 litres and 15 cm deep for one plant. A raised bed wants 5 litres of soil and 20 cm of depth.
How often should I water viola?
About 500 ml per 10 litres of soil, every 2 days in normal weather — daily when it is hot and every 3 days when cool. Water in the early morning.
What temperature does viola need?
It does best between 10 °C and 18 °C and survives from -5 °C to 25 °C. Seed needs soil above 15 °C to germinate, ideally around 18 °C.
Can I grow viola in winter?
It tolerates cold better than most, down to about -5 °C, so a sheltered spot or a cold frame will often carry it through.
How do I know when viola is ready to harvest?
Fully open, vibrant flowers. Once picked: use fresh immediately or store in a sealed container in the refrigerator for a few days.
How much does one viola plant produce?
Roughly 0.1 kg from a 20 litre container, or about 0.2 kg in open ground. Larger containers give proportionally more, up to a point.
