Lettuce

Lactuca sativa

خس

A cool-season crop for Dubai's best weeks: sow from October to February, pick from December to April, and expect bolting and bitterness once the days pass the high 20s.

Bolting and bitterness

  • Main sowing window: Oct–Feb

    Ministry calendar: nursery September–November, field October–December. Sow little and often every two weeks, in trays at first while the weather is still warm.

  • Plant out seedlings: Oct–Dec

    Ministry calendar: field planting October–December; thin or space plants 15–20 cm apart.

  • Aphids and snails: Nov–Mar

    UF/IFAS lists aphids, slugs and snails as the usual pests.

  • Cut leaves or heads: Dec–Apr

    Take outer leaves, or cut a head two thirds down and let it regrow; crisphead types are a single harvest.

  • Bolting and bitterness: Apr–May

    UF/IFAS: above about 29°C lettuce needs afternoon shade; too much heat makes it bolt and turn bitter.

Lettuce has the shortest season in the library. Nursery trays are sown from late September or October, with seedlings planted out from October to December and direct sowing every two weeks from October to February. Leaves are ready after 50 to 60 days, so cutting runs from December to April, with outer-leaf harvests and cut-and-come-again regrowth stretching each plant. Aphids and snails need watching from November to March. By April, rising heat pushes plants to bolt and turn bitter, and shade cloth or pulling the bed marks the end of the season until the next October.

Meet the plant

Meet the Lettuce

Meet lettuce, the crop that tells you winter has arrived. For a few months Dubai's weather gives it exactly what it wants: warm days that stay under 25°C, cool nights and sun that is bright without being fierce, and in those weeks it grows from seedling to salad in around two months.

Its character is fresh, quick and a little fragile. A bed of lettuce changes week by week, and each new cut leaf makes the next arrive faster. It dislikes heat intensely, which is why the whole crop is over by April, when plants send up a tall bitter stem and finish.

What it brings is the plainest and most delightful kind of garden pleasure: a handful of leaves cut and eaten within the hour, crisp and sweet in a way a shop-bought head rarely is. A tray of different leaf types makes a salad bed with real variety.

Lettuce is the salad crop that makes the most of Dubai's mild winter. The Ministry of Climate Change and Environment's calendar lists nursery sowing from September to November and field planting from October to December, with harvest 50 to 60 days later; garden-centre calendars say to sow October to February. Lettuce is one of the crops the Ministry named when it encouraged residents to grow food at home under the Plant the Emirates programme in October 2024.

UF/IFAS gives the technical limits: lettuce thrives at 10 to 24°C, needs afternoon shade or shade cloth once temperatures pass about 29°C, and bolts prematurely in heat, leaving bitter leaves. Dubai's average daily maximum is about 24 to 27°C from December to February and 29°C by March, so the sweet spot runs from December to March. Keep the soil consistently moist, since soggy ground promotes disease and dry spells accelerate bolting. FAO rates lettuce as moderately sensitive to salt, with a threshold of about 1.3 dS/m.

Leaf, butterhead and romaine types can be harvested cut-and-come-again: take the outer leaves, or cut the whole head two thirds of the way down and let it regrow. Crisphead types are a single harvest. In the plot, sow little and often every two weeks, thin to 15 to 20 cm, and plant where afternoon shade falls in March. Aphids, slugs and snails are the usual pests (UF/IFAS), and a quick morning check of the outer leaves is usually all the protection a small bed needs. Lettuce is also a good first crop for children and for a balcony trough, because the whole cycle from seed to salad takes only about two months.

Design

Where to use it

Raised-bed salad cropContainer or trough cropEdible edgingCool-season filler between summer crops

Plant lettuce in a bed or trough that gets morning sun and light afternoon shade, near the kitchen, so it is picked young and often. A raised bed with free-draining, compost-rich soil works well, as do shallow troughs on a terrace. In March, a trellis or taller crop can cast helpful shade over the bed. Keep it out of the lawn's sprinklers, but within reach of a drip line or hose, since even moisture matters.

A quick salad partner; a trellis in March can give light afternoon shade to lettuce finishing its season.

A cool-season companion with a longer season; plant lettuce in the gaps while the tomatoes are small.

Care guide

How to grow it in Dubai

Watering

Summer: Not grown in summer in Dubai; the season ends in April as temperatures rise.

Winter: Every one to two days in light, fast-draining soil, keeping the surface consistently moist but not soggy (UF/IFAS).

Establishment: Keep the seed bed or tray evenly moist until seedlings are established; shade lightly in the warm weeks of October.

Soil
Well-drained soil enriched with compost. UF/IFAS notes soggy conditions promote disease; raised beds and containers drain well.
Feeding
Compost at sowing and a light liquid feed every two weeks; lettuce needs steady, gentle nutrition rather than heavy nitrogen.
Pruning
Harvest outer leaves first, or cut a leaf-type head two thirds of the way down to let it regrow (UF/IFAS).
Planting
Sow October–February in trays or direct, plant out October–December 15–20 cm apart (about 25 cm for crisphead), and sow every two weeks for a steady supply.

Avoid these

Common mistakes

  • Sowing everything at once. Lettuce bolts as the weather warms, so sow little and often every two weeks to avoid a single glut.
  • Planting too early in October. The weather can still be hot, so start seed in trays in shade or wait until nights ease.
  • Letting the soil dry out. Lettuce has shallow roots and bolts sooner when stressed; keep the surface evenly moist.
  • Leaving it past March. Above about 29°C it needs afternoon shade, and in April it bolts and turns bitter.
  • Using salty water. FAO rates lettuce as moderately sensitive to salinity, with a threshold of about 1.3 dS/m.

Extra notes

Good to know

  • UF/IFAS says lettuce does best between 10 and 24°C, needs afternoon shade or shade cloth when temperatures exceed about 29°C, and needs frost protection below about 4°C, which Dubai rarely sees.
  • Leaf, butterhead and romaine types can be harvested cut-and-come-again; crisphead (iceberg) is harvested once.
  • Lettuce is one of the crops named by MoCCAE when it launched the Plant the Emirates home-growing drive in October 2024, alongside okra, rocket and radish.
  • Dubai's average daily maximum rises from 24°C in January to 29°C in March and 34°C in April, which is the clock that ends the lettuce season.

Toxicity: Not known to be toxic; lettuce is a normal food.

Pros

  • Ministry calendar gives 50–60 days to harvest; leaf types allow repeated pickings
  • Thrives in Dubai's mild winter, with December to March the best months
  • Tolerates part shade, and afternoon shade helps as days warm
  • Small and shallow-rooted: ideal for troughs, window boxes and raised beds

Cons

  • Bolts and turns bitter in heat (UF/IFAS), so the crop ends by about April
  • Moderately salt-sensitive (FAO threshold about 1.3 dS/m); needs clean water
  • Shallow roots dry out fast, so it needs steady moisture
  • Aphids, slugs and snails are the usual pests (UF/IFAS)

FAQ

Common questions

When should I sow lettuce in Dubai?
From October to February. The Ministry's calendar gives nursery sowing from September to November and field planting from October to December; garden centres say October to February.
How long does lettuce take to grow?
The Ministry's calendar gives 50 to 60 days to harvest; UF/IFAS says four to six weeks from planting for transplants.
Why does my lettuce taste bitter?
Heat. UF/IFAS says too much heat makes lettuce bolt and turn bitter. Provide afternoon shade as temperatures climb and harvest before April.
Can I harvest lettuce more than once?
Leaf, butterhead and romaine types, yes: pick outer leaves, or cut the head two thirds down and let it regrow (UF/IFAS). Crisphead is a single harvest.
Can I grow lettuce on a balcony?
Yes, in shallow troughs or pots with compost-rich soil and morning sun. Water often, since shallow roots dry quickly.
What pests should I look for?
Aphids, slugs and snails (UF/IFAS). Check leaf undersides and keep the bed tidy.
