Swiss chard
Also called: سلق · سلق أحمر · Silq · Chard
The longest-cropping leaf in a Qatari season — November to May from one sowing. It takes heat and salt better than lettuce or spinach, which makes it the most forgiving leafy crop for a beginner.

Stage by stage
Stage 1 of 7
Seed
Days 0–5
Seed
Days 0–5The 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
A chard "seed" is a cluster of several seeds, like beetroot, so expect several sprouts from each. Soak overnight before sowing.
Germination
Days 6–12The 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
Up in about a week in October soil. It germinates in warmer ground than spinach, which is why you can sow it a month earlier.
Seedling
Days 13–30The 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
Thin by snipping, not pulling, so the neighbours keep their roots. The thinnings make a perfectly good baby-leaf salad.
Leaf growth
Days 31–49Leaves multiply fast and the rosette widens. All the energy goes into leaf — which is the crop itself, so speed is the goal.
Do now
- Feed nitrogen every ten days. Leafy crops want more of it than anything else you grow.
- Keep the moisture even. Any drought turns the leaves bitter and tough, permanently.
- Clear competing weeds. Leafy crops root shallowly and lose the competition easily.
Watch for
- Small, thick, dark leaves: the plant is thirsty or the soil is salty.
- Aphids gathering in the heart of the plant, where they are hard to wash out.
In Qatar
Salty well water suits chard better than most leaves, but leach the bed every second week: salt shows first as dull, thick leaves.
Harvest
Days 50–170The leaves have reached size and are at their most tender. The window is short before the plant starts running to flower.
Do now
- Pick the outer leaves and leave the heart growing — you can crop the same plant for weeks.
- Harvest early in the morning. Leaves cut at midday wilt within an hour in Qatar’s air.
- Rinse in cold water straight after cutting and refrigerate immediately.
Watch for
- A stalk starting to rise from the centre: the plant is about to bolt — harvest everything now.
- Bitterness appearing suddenly after a hot spell.
In Qatar
The longest leaf-cropping season in this guide: November to May. Take the outer leaves weekly and the heart keeps producing.
Bolting
Days 171–195Heat or lengthening days convince the plant its life is ending, so it rushes to make seed. The leaves turn bitter and tough.
Do now
- The leaves are past salad use. Cook them if the bitterness is bearable.
- Let the strongest plant finish flowering and collect its seed for another season.
- The flowers pull in beneficial insects, so leave some standing if you have another crop nearby.
Watch for
- Early bolting caused by sowing too late in the season — the commonest mistake in Qatar.
- Seed scattering itself and coming back as a weed next season.
In Qatar
It bolts with May’s heat. Cut the plant back hard and shade it, and it may regrow in September.
End of cycle
Days 196–220The plant’s cycle is over. The roots left behind break down and add organic matter if you leave them.
Do now
- Cut the plant at soil level and leave the roots in place to rot down.
- Sow a crop from a different family in the same spot to break the pest cycle.
- Add compost and cover the soil before the summer heat.
Watch for
- Planting the same family twice running in the same bed.
- Leaving the soil bare in the sun all summer.
In Qatar
Pull it in June and rest the soil, or leave one plant in full shade all summer: a chard that survives gives leaf again from September.

Soil preparation
Not fussy, but it repays nitrogen with bigger leaves. Three kilos of compost per square metre is enough, with a mulch to hold the moisture.
Pests
Leafminer
- Sign
- Wide transparent window-like patches inside the leaf.
- What to do
- Strip and destroy affected leaves. Sprays cannot reach a grub inside the leaf, but the plant replaces them quickly.
Aphids
- Sign
- Clusters on the young leaves at the heart, which curl.
- What to do
- Water blast twice a week. Chard tolerates aphids better than most leaf crops.
Common problems
Small, thick, dark leaves
- Cause
- Salt building up in the root zone from brackish well water.
- Fix
- Water at double the usual volume every second week to flush the salt, and mulch to cut evaporation.
Bolting in the heat
- Cause
- Temperatures above about 30 °C in April and May push the plant to flower and the leaves toughen.
- Fix
- Shade from April and harvest hard. Once it has flowered fully, resow rather than wait for it.
Picking
Pick the outer leaves at 20–30 cm close to the base and leave the heart. You can crop weekly for months from the same plant.
Keeping
Five days in the fridge. Stalk and leaf are cooked together, and it freezes well after blanching.
