Bell pepper
Also called: فلفل رومي · فلفل حلو · Filfil Roumi · Capsicum
The hardest of this family in Qatar — it wants mild warmth, unwavering water and shelter from midday sun. Try it after you have succeeded with tomato.
The year at a glance
Each month is split in half. The outline marks now.
Stage by stage
Stage 1 of 9
Seed
Days 0–7
Seed
Days 0–7The seed sits in the soil taking up water and swelling. Nothing shows above the surface — everything is happening underground.
Do now
- Water lightly and often so the soil stays damp but never soaked. Letting it dry out between waterings kills the seed before it sprouts.
- Cover the surface with a thin layer of straw or compost to slow evaporation and steady the temperature.
- Label what you sowed and when. You will need the date to work out the harvest.
Watch for
- A hard crust forming on sandy soil after watering, which traps the sprout underneath. Break it gently.
- Ants carrying small seeds away — a very common problem in Qatari gardens.
In Qatar
Sow in August despite the heat. Pepper needs 140 days, and any delay pushes fruiting into the April heat.
Germination
Days 8–16The seed coat splits: a root pushes down and a shoot pushes up. The two seed leaves that appear are not true leaves — they are the seed’s own food store.
Do now
- Keep moisture constant. The first root is very fine and a single dry day can end the seedling.
- Remove any covering as soon as the first sprout shows, or it will stretch thin looking for light.
- Give bright, indirect light. Direct midday sun will scorch a new seedling within hours.
Watch for
- A long, thin, pale stem: the seedling is not getting enough light and will collapse.
- Sudden wilting with a pinched stem at soil level — damping off, caused by overwatering.
In Qatar
A week slower than tomato. Do not give up and re-sow before day 16.
Seedling
Days 17–40The first true leaves appear, shaped differently from the seed leaves. The plant is now feeding itself and the roots are branching fast.
Do now
- Thin crowded seedlings and keep the strongest. Crowding gives you many weak plants instead of one good one.
- Start watering less often but more deeply, to drive the roots downwards.
- Harden the seedling off — build up its sun exposure over a week before transplanting.
Watch for
- Yellowing lower leaves: nitrogen shortage, very common in Qatar’s poor sandy soil.
- Small holes or chewed edges, meaning snails or young grasshoppers.
In Qatar
The most fragile seedling of this family. Keep it under 50% shade until at least mid-October.
Vegetative growth
Days 41–68The plant is building its frame — stem, leaves, branches. Every leaf added now means more fruit later, because leaves are the sugar factory.
Do now
- Stake the plant now while it is small — staking late damages the roots.
- Feed with a nitrogen-rich fertiliser every two weeks to push leafy growth.
- Water deeply in the early morning. Evening watering plus high humidity invites fungal disease.
- Check the undersides of leaves weekly for whitefly and aphids.
Watch for
- Lush leaves but no flowers: too much nitrogen. Stop the nitrogen feed.
- Midday wilting even though the soil is moist: heat stress — the plant needs shade.
In Qatar
Plant peppers slightly closer together in Qatar than the books say — they shade each other and protect the fruit from scald.
Flowering
Days 69–84The plant switches from building a body to making offspring. Flowers open, and every one that is successfully pollinated becomes a fruit.
Do now
- Cut back nitrogen and raise potassium and phosphorus to support fruit set.
- Never let the soil dry out completely between waterings. Drought now makes the flowers drop.
- Shake the plant gently in the morning, or use a small brush, to help pollination if bees are scarce.
Watch for
- Flowers dropping without setting fruit: above about 35 °C the pollen goes sterile. Get shade over it now.
- No pollinating insects at all — common on enclosed roofs and balconies.
In Qatar
Pepper flowers drop above 32 °C and below 15 °C. Cold Murabbaniya nights may pause fruit set — that is normal.
Fruit set
Days 85–104The petals wither and the ovary behind them swells. Small, hard green fruits appear and grow day by day.
Do now
- Make watering perfectly regular. Swinging between dry and drenched causes most fruit cracking and rot.
- Support the fruiting branches before the weight breaks them.
- Add calcium if your irrigation water is brackish, to head off blossom-end rot.
Watch for
- A sunken brown patch at the base of the fruit: calcium shortage from irregular watering or salinity.
- Small fruits yellowing and dropping: the plant is carrying more than it can feed, or it is thirsty.
In Qatar
Pinch off the first flower to open (the crown bud). It delays harvest by a week but roughly doubles the total crop.
Ripening
Days 105–125The fruit stops growing and starts changing colour, turning its starch into sugar. Heat speeds this stage up.
Do now
- Ease off the water slightly to concentrate the flavour — but never to the point of wilting.
- Shade exposed fruit with the plant’s own leaves to prevent sunscald.
- Pick as things ripen. Leaving fruit on the plant stops it setting new ones.
Watch for
- White or leathery brown patches on the sun-facing side: sunscald.
- A small hole with rot inside, meaning fruit worm.
In Qatar
The green-to-red turn speeds up in March’s warmth, which is the best time to leave fruit on the plant.
Harvest
Days 126–175The fruit is ready. The plant is at peak production and will keep bearing as long as you keep picking and the weather holds.
Do now
- Pick in the early morning when the fruit is full of water and will keep longest.
- Use scissors rather than pulling by hand, so you do not tear the branch.
- Keep feeding potassium every two weeks to stretch the picking season out.
Watch for
- New fruit coming smaller: the plant is exhausted and needs feeding.
- The seasonal heat rising, which will shut production down within weeks.
In Qatar
Always cut with scissors. Pepper stems are brittle and pulling by hand snaps off the whole fruiting branch.
End of cycle
Days 176–210Production tails off and the leaves yellow. As the heat builds the plant stops setting fruit altogether.
Do now
- Bring in the last of the fruit, even the ones not fully ripe.
- Save seed from the best fruit on the strongest plant if you want to grow it again.
- Pull the plant and compost the healthy remains; bin or burn anything diseased.
- Work compost into the soil now, ready for the next Al-Wasm.
Watch for
- Leaving diseased plants in the ground carries pests over to next season’s crop.
- Bare soil under the sun goes dead. Cover it or sow a green manure.
In Qatar
The season ends in April, a month before eggplant. Do not try to carry it through summer.

Soil preparation
Very salt-sensitive. Flush the bed with fresh water before planting if you irrigate from a well, and add plenty of compost.
Pests
Thrips
- Sign
- Silvery scarring on leaves and fruit, and distorted new growth.
- What to do
- Blue sticky traps and neem oil. Thrips carry incurable viruses, so prevention is the only real answer.
Aphids
- Sign
- Curling tender leaves and sticky clusters on the tips.
- What to do
- Water blast then potassium soap. Check weekly through the mild winter.
Common problems
Sunscald
- Cause
- Fruit exposed to direct midday sun — very common here because the plant is short and does not shade its own crop.
- Fix
- Fit 30% shade netting from February, and never prune off the leaves that shade the fruit.
Small, thin-walled fruit
- Cause
- Salty irrigation water, or not enough potassium.
- Fix
- Over-water every second week to leach the salts, and feed potassium weekly once fruit sets.
Picking
Pick green, or leave it to turn red. Red is sweeter and higher in vitamin C but takes three extra weeks and reduces total yield.
Keeping
Two weeks in the fridge drawer. Only freeze it sliced.
