Muskmelon
Also called: شمام · بطيخ أصفر · Shammam · Cantaloupe
Two weeks quicker than watermelon and needs less room, which makes it the better choice for an average villa garden.
The year at a glance
Each month is split in half. The outline marks now.
Stage by stage
Stage 1 of 9
Seed
Days 0–4
Seed
Days 0–4The 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 after mid-January. Muskmelon is more cold-sensitive than watermelon and wants warmer soil.
Germination
Days 5–10The 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
Warm the soil under clear plastic for a week before sowing — a useful trick in a Qatari January.
Seedling
Days 11–24The 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
Shelter the seedling from February’s northerlies with a simple windbreak. Wind dries small leaves faster than sun does.
Vegetative growth
Days 25–44The trailing stems run fast and tendrils appear. The plant is hunting for something to climb, and training it now decides the shape of the whole crop.
Do now
- Put the trellis up now and train the stems onto it. Getting the vine off the ground cuts disease and pests dramatically.
- Tie the stems with soft, wide strips of cloth rather than thin twine that cuts in.
- 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
- Stems trailing on hot ground and scorching underneath.
- Lush leaves but no flowers: too much nitrogen. Stop the nitrogen feed.
In Qatar
Pinch the main runners after the fifth leaf to force side shoots — those are what carry the female flowers.
Flowering
Days 45–56Male flowers open first, then female ones with a miniature fruit already behind them. Only the female flowers bear, and pollen has to reach them.
Do now
- If nothing is setting, hand-pollinate: pick a male flower and dab it into the centre of a female one in the morning.
- 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.
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
Flowering in March is ideal. April flowers set smaller fruit because of the heat.
Fruit set
Days 57–68The 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
Keep three fruit per plant. The plant can sweeten all of them in Qatar’s sun.
Ripening
Days 69–80The 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
Qatar’s strong April sun raises the sugar noticeably. Do not shade the fruit during this stage.
Harvest
Days 81–95The 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
Check daily from day 75. The perfect-ripeness window is only about 48 hours in this weather.
End of cycle
Days 96–120Production 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
Over with June’s heat. Save seed from the sweetest fruit — locally adapted lines always do better.

Soil preparation
Prefers light, free-draining soil — Qatar’s sand suits it well once you add organic matter to the hole.
Pests
Fruit fly
- Sign
- Punctures in the rind and internal rot showing up near ripeness.
- What to do
- Bag each fruit in paper once it reaches egg size.
Powdery mildew
- Sign
- White coating on the leaves appearing as April warms up.
- What to do
- Spray a milk solution weekly from March as prevention, not cure.
Common problems
Fruit that is not sweet
- Cause
- Picking early, or heavy watering in the last fortnight.
- Fix
- Wait until the fruit slips from the stem under light thumb pressure — the only reliable sign there is.
Fruit splitting at ripeness
- Cause
- A sudden heavy watering on a ripe fruit.
- Fix
- Taper the water down over the last two weeks rather than stopping abruptly.
Picking
The decisive sign is the "slip": a ripe melon separates from its stem under thumb pressure without cutting. A sweet smell at the blossom end confirms it.
Keeping
Five days whole in the fridge. A ripe melon perfumes the whole fridge, so wrap it.
