No planting window in summer

Jun – Aug
  • Nursery sowing windows: Feb–Mar, Aug–Oct

    Ministry calendar: February–March for a spring crop and August–October for an autumn crop. Use shaded trays while the days are still hot.

  • Plant out seedlings: Mar–Apr, Sep–Nov

    Ministry calendar: field planting March–April and September–November. UF/IFAS spacing is 60 cm between plants in rows 90 cm apart.

  • Cut small and often: Apr–May, Oct–Dec

    Ministry calendar: about 35 days after planting (UF/IFAS: 40–50). Frequent harvesting keeps the plant producing.

  • Mildew, aphids and leafminers: Mar–Apr, Nov–Jan

    UF/IFAS lists powdery and downy mildew, aphids, leafminers, squash bugs and cucumber beetles. Whiteflies and leafminers rank among the top insect pests on UAE vegetable farms.

  • No planting window in summer: Jun–Aug

    The Ministry's windows run February to April and August to November. Dubai's mean high is 40°C in June and 41.9°C in August.

Zucchini fits two short seasons either side of the Dubai winter. For the autumn crop, seed goes into trays from August to October and seedlings are planted out from September to November; fruit is ready about 35 days later, so cropping runs from late October into December. For the spring crop, trays are sown in February and March, planted out in March and April, and fruit arrives in April and May. Mildew, aphids and leafminers need watching through the cool months. There is no planting window between April and August, when Dubai's mean highs reach 34 to 42°C.

Meet the plant

Meet the Zucchini

Meet zucchini, the vegetable that is never behind schedule. Sown in a tray in September and planted out in October, it can be a sprawling plant covered in yellow flowers a few weeks later, and the first fruit is ready in about five weeks.

Its character is generous and a little wild. It spreads over a metre of bed, produces more than a family can eat once it gets going, and rewards a daily look. Pick the fruit small and often, and the plant carries on producing.

What it brings is quick, easy abundance in the cool months, and a way to fill a bed before spring. Two short seasons, one in autumn and one in spring, fit neatly either side of Dubai's winter.

Zucchini is one of the quickest crops in a Dubai garden. The UAE Ministry of Climate Change and Environment's calendar lists it with 35 days to harvest and two windows: nursery sowing from February to March for field planting in March to April, and nursery sowing from August to October for field planting from September to November. For the cool season the autumn window is the one to use, since plants set out in October can be cropping by late November, well ahead of the spring warm-up. UF/IFAS, writing for Florida, gives 40 to 50 days from planting to harvest.

The plant carries separate male and female flowers on the same vine, and UF/IFAS says pollination by insects or by hand is necessary for fruit to set; wrinkled fruit and fruit that drops while small are signs of poor pollination. It also asks growers to protect the bees that matter for fruit set, to avoid insecticides where they can, and to spray only in the evening when bees are less active. Zucchini leaves often carry natural pale greenish-grey splotches that are easy to mistake for powdery mildew, so check before treating. Powdery and downy mildew, aphids, leafminers and squash bugs are the real concerns.

Give it full sun, which Gulf News' UAE guide lists for zucchini, tomatoes and peppers, and a raised bed of sweet soil and compost. UF/IFAS spaces plants 2 feet (about 60 cm) apart in rows 3 feet (about 90 cm) apart, plants seed 1 to 1.5 inches (2.5 to 4 cm) deep, and says four to six plants feed a family of four. Mulch conserves moisture and keeps fruit out of the dirt. Cut the fruit with an inch or two of stem, and often, because frequent harvesting keeps the plant producing. FAO rates zucchini as moderately tolerant of salt, with a threshold near 4.9 dS/m, better than most vegetables.

Design

Where to use it

Raised-bed vegetableQuick-cropping fillerKitchen-garden stapleLarge-container crop

Plant zucchini in a sunny raised bed with room to sprawl, near enough to the house to check flowers and cut fruit daily. Fix a drip line on a timer and mulch the soil. Rotate the bed each year, since cucumbers, pumpkins and zucchini share a plant family and its pests.

Care guide

How to grow it in Dubai

Watering

Summer: Not grown in summer; the Ministry's windows end in November and restart in February.

Winter: Water deeply from a drip line finishing before 8 am (DEWA), keeping the soil evenly moist. Water at the base rather than over the leaves.

Establishment: Water seedlings daily and shade them lightly at first in September and October. Mulch to hold moisture and keep fruit off the soil (UF/IFAS).

Soil
A raised bed of sweet soil blended with compost, 30 to 45 cm deep, in full sun. Gulf News suggests compost or manure and perlite or sweet sand for drainage.
Feeding
Work compost or well-rotted manure into the bed before planting (Gulf News) and top up with a balanced liquid feed if growth slows while the plant is cropping.
Pruning
No pruning is needed. Harvest by cutting the stem so an inch or two stays on the fruit, and wear gloves because the stems can have sharp spines (UF/IFAS).
Planting
Sow in shaded trays from August to October (or February to March), plant out from September to November (or March to April), 60 cm apart. A single plant in a large pot is the balcony scale.

Avoid these

Common mistakes

  • Planting out in summer. The Ministry gives no window between April and August, and zucchini sown in the heat struggles.
  • Spraying insecticide in the daytime. UF/IFAS asks growers to protect bees, which matter for fruit set, and to spray only in the evening if they must.
  • Treating natural leaf splotches as mildew. UF/IFAS notes that zucchini leaves carry pale greenish-grey markings; check before you spray.
  • Leaving fruit to grow huge. UF/IFAS says frequent harvesting keeps the plant producing, so cut small and often.
  • Crowding plants. UF/IFAS spaces them 60 cm apart in rows 90 cm apart, which leaves room to inspect leaves for mildew and pests.

Extra notes

Good to know

  • UF/IFAS: wrinkled fruit and early fruit drop are signs of poor pollination, since the plant needs insects or hand pollination for fruit to set.
  • The male flowers can be eaten; UF/IFAS says to pick them with the stamens complete, the day before or the morning of opening.
  • Zucchini is called courgette in Britain and France (Wikipedia). Both names are used in UAE shops.
  • The Ministry lists a separate Armenian cucumber and cucumber with similar windows, but zucchini fruit sooner, at 35 days.

Toxicity: Zucchini is non-toxic to dogs, cats and horses according to the ASPCA, and its vegetable-garden guide lists zucchini among garden crops that can be fed as snacks in moderation. It is a normal food for people.

Pros

  • Ready about 35 days after planting, one of the fastest vegetables (Ministry calendar)
  • Two windows a year: autumn and spring (Ministry calendar)
  • Moderately salt tolerant, with an FAO threshold near 4.9 dS/m
  • Four to six plants feed a family of four (UF/IFAS)
  • Non-toxic to dogs, cats and horses (ASPCA)

Cons

  • Not a summer crop: the Ministry gives no window between April and August
  • Needs bees or hand pollination to set fruit (UF/IFAS)
  • Powdery and downy mildew, aphids and squash bugs are common (UF/IFAS)
  • Sprawling plants need about 60 cm between them and a sunny bed

FAQ

Common questions

When should I plant zucchini in Dubai?
The Ministry's calendar gives nursery sowing from August to October for field planting from September to November, and a spring window of February to March for planting in March to April. For the cool season, plant out in October.
How long does zucchini take to fruit?
The Ministry gives 35 days to harvest. UF/IFAS gives 40 to 50 days for Florida. Pick fruit small and often.
Why do my zucchini flowers fall without fruit?
Pollination. UF/IFAS says pollination by insects or by hand is needed, and wrinkled or prematurely dropping fruit signals poor pollination. Check that female flowers, the ones with a small fruit behind the bloom, are being visited.
Are the grey patches on the leaves mildew?
Often not. UF/IFAS says zucchini leaves have natural light greenish-grey splotches that are mistaken for mildew. Powdery mildew is a white, dusty coating.
Can I grow zucchini on a balcony?
One plant in a large pot with a drip line or daily watering is realistic, in full sun, though it will spread. The Ministry's two windows, autumn and spring, apply to pots as well.
Is zucchini safe for pets?
The ASPCA lists zucchini squash as non-toxic to dogs, cats and horses, and its garden guide lists it among crops that can be fed as snacks in moderation.
