Beetroot
Also called: شمندر · بنجر · Shamandar · Banjar
The best root crop for Qatar’s salty soil — it takes salinity that would kill a carrot outright. The leaves are edible too, like chard.
The year at a glance
Each month is split in half. The outline marks now.
Stage by stage
Stage 1 of 7
Seed
Days 0–6
Seed
Days 0–6The 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
Soak the capsules 24 hours. Their corky shell repels water and is the main cause of patchy germination.
Germination
Days 7–15The 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
Expect several sprouts from each capsule. That is entirely normal for beetroot.
Seedling
Days 16–32The 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 at soil level, never by pulling — in sandy soil pulling takes the neighbours with it.
Top growth
Days 33–52The plant builds its leaves first. The root is still thin, but the size of the leaf canopy now decides the size of the root later.
Do now
- Thin to the recommended spacing. Crowding is the number one cause of small, deformed roots.
- Clear stones and clods from the soil around the plant. Any obstruction makes the root fork.
- Water regularly and deeply. Roots follow the water down.
Watch for
- Very lush leaves: too much nitrogen, and you will get foliage instead of a root.
- Compacted or very sandy soil stopping the root from expanding.
In Qatar
You can take some outer leaves to eat without hurting the root — two crops from one plant.
Root filling
Days 53–70The plant moves sugar from the leaves down into the root, which swells fast. You can often see the shoulder pushing above the soil.
Do now
- Keep watering perfectly steady. Swinging between dry and drenched splits the root.
- Cover any exposed shoulder with soil or mulch to stop it greening and going tough.
- Stop nitrogen completely and switch to potassium.
Watch for
- A lengthwise split in the root after a sudden heavy watering.
- Fine tunnels on the root surface, meaning root fly.
In Qatar
Beetroot handles brackish well water through this stage better than any other root here.
Harvest
Days 71–100The root has reached size. Leaving it past this window makes it woody, hot-tasting or hollow.
Do now
- Water a few hours before lifting so the root pulls cleanly out of sandy soil.
- Lever from the side with a fork rather than pulling the leaves, which just snap off.
- Cut the tops off right after lifting, or they draw moisture out of the root.
Watch for
- A cracked or hollow root from harvesting too late.
- A sharp, hot taste, which means heat stress during growth.
In Qatar
Harvest in passes — lift the big ones and leave the small ones another fortnight.
End of cycle
Days 101–125The 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
The season ends in March. Anything left through April’s heat turns woody and useless.

Soil preparation
Wants 20 cm of improved soil. Less demanding than carrot and forgiving of some stones.
Pests
Leafminer
- Sign
- Broad transparent patches in the leaves.
- What to do
- Remove affected leaves. The root is fine as long as half the tops stay healthy.
Aphids
- Sign
- Clusters under the leaves.
- What to do
- A strong water blast weekly.
Common problems
Several plants from one seed
- Cause
- A beetroot "seed" is a capsule holding two to four seeds. This is normal, not a mistake.
- Fix
- Thin to one by snipping rather than pulling, so you do not disturb the others’ roots.
White rings inside the root
- Cause
- Heat stress or stop-start growth.
- Fix
- Water steadily and harvest before April. The rings are harmless but they cost sweetness.
Picking
Lift at 5–7 cm across; bigger than that goes woody. The young leaves make an excellent salad.
Keeping
Three weeks refrigerated. Leave 3 cm of stalk on so it does not bleed colour when cooked.
