Parsley keeps producing once it starts. First picking comes around day 70, and the plant then crops for roughly 120 more days — but only if you keep picking. Letting it run to flower is what ends the supply.
Short answer
Grow parsley in a 5 litre container at least 15 cm deep, watering about 600 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 parsley need?
5 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 | 5 L | 15 cm | Ensure good drainage |
| Grow bag | 5 L | 15 cm | Good for aeration |
| Open ground | — | 20 cm | Space plants 15-20cm apart |
| Raised bed | 10 L | 20 cm | Provides excellent drainage |
Watering
How often should you water parsley?
Every 3 days through the growing season, at about 600 ml per 10 litres of soil — daily in hot weather, every 4 days when it turns cool. Water in the early morning. Bottom watering or at soil level works best.
Too little water
- wilting leaves
- yellowing leaves
- stunted growth
Too much water
- yellow lower leaves
- soft stem
- root rot
Avoid: water on leaves (can promote fungal diseases); standing water; letting soil dry out completely.
Climate
Can you grow parsley where you live?
No hardiness zone needed — compare your actual temperatures against the plant's own limits.
| Ideal range | 15 – 24 °C |
|---|---|
| Survives | -5 – 30 °C |
| Germinates above | 10 °C — best at 20 °C, about 18 days |
| Flowers drop | above 28 °C, or below 5 °C |
| Sunlight | 4–8 hrs/day, best 6 |
| Frost | Medium 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 parsley fails, and how to avoid it
- A container that is too small
Below 5 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. Parsley wants about 600 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 Lettuce
Competes for soil nutrients and light, potentially stunting parsley growth.

Problems
Parsley 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. May secrete sticky honeydew.
Carrot Rust Fly humidity moderate to high · temp 10-20
Larvae tunnel into the roots, causing damage and making roots inedible. Parsley is a host plant, especially if grown near carrots.
Parsleyworm humidity any · temp warm, sunny
Large, green caterpillars with black and yellow stripes. They feed on parsley leaves, often defoliating plants quickly. Can be hand-picked.
Septoria Leaf Spot humidity >70% · temp 18-24
Small, circular spots with dark borders and light centers appear on leaves, often leading to yellowing and defoliation. Spreads in wet conditions.
Powdery Mildew humidity high · temp 20-27
White, powdery patches on leaves and stems, hindering photosynthesis and weakening the plant. Often due to poor air circulation.
Damping Off humidity high · temp cool, wet soil
Seedlings suddenly wilt and collapse at the soil line, often due to fungal pathogens in overly wet soil. Prevent with good drainage and sterile soil.
Root Rot humidity any · temp any
Roots become soft and mushy, leading to wilting and yellowing of foliage. Caused by excessive soil moisture and poor drainage.
Bolting humidity any · temp >27 or long days
Plant prematurely sends up a flower stalk, causing leaves to become bitter and tough. Often triggered by heat stress, inconsistent watering, or long daylight hours.
Harvest
When to harvest parsley
First picking falls between day 70 and day 90, and the plant then keeps producing for about 120 days. Pick often — what you leave on the plant signals it to stop making more.
How to tell it's ready
- Outer leaves are at least 6 inches (15 cm) long
- Vibrant green color
- Plant has established a good clump of foliage
How much to expect
Storing it: Place stems in a glass of water in the refrigerator, covered loosely with a plastic bag. Can also be dried or frozen.
Questions
Parsley: common questions
How long does parsley take to grow?
About 80 days from sowing to the first harvest, with picking usually starting between day 70 and day 90. It then keeps producing for roughly 120 more days. Warm weather pulls that forward; cool weather pushes it back.
What size pot does parsley need?
At least 5 litres and 15 cm deep for one plant. A raised bed wants 10 litres of soil and 20 cm of depth.
How often should I water parsley?
About 600 ml per 10 litres of soil, every 3 days in normal weather — daily when it is hot and every 4 days when cool. Water in the early morning.
What temperature does parsley need?
It does best between 15 °C and 24 °C and survives from -5 °C to 30 °C. Seed needs soil above 10 °C to germinate, ideally around 20 °C.
Can I grow parsley 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 parsley is ready to harvest?
Outer leaves are at least 6 inches (15 cm) long; Vibrant green color; Plant has established a good clump of foliage. Once picked: place stems in a glass of water in the refrigerator, covered loosely with a plastic bag. can also be dried or frozen.
How much does one parsley plant produce?
Roughly 0.4 kg from a 20 litre container, or about 1 kg in open ground. Larger containers give proportionally more, up to a point.
