Mango and guava tree care in Dubai: sun, water, feeding and pests

Mango and guava can both grow in a Dubai garden with full sun, regular deep watering and feeding, and some care in the first years. Mango is the bigger tree. Guava is more compact and suits a large pot. Neither is low-maintenance in the UAE's sandy, salty soil.

Key takeaways

• Both want full sun and shelter from strong, drying wind.
• Water deeply and regularly while young. Mulch to keep roots cooler.
• Sandy soil needs compost and regular feeding to support growth.
• Prune lightly to keep size down and open the canopy.
• Young trees can lose leaves after a move or in cold snaps. Most recover.

How much sun do mango and guava need?

Full sun for most of the day. A young tree that moves from a shaded nursery into hard summer sun can scorch, so introduce it gradually and keep the root zone well watered. Wind-shelter helps flowers and fruit set.

How often should you water mango and guava in Dubai?

Young trees need steady, deep watering. In summer, a drip ring or bubbler running a few times a week, early in the morning, helps roots go deep. Add a thick layer of mulch (not touching the trunk) to slow evaporation. In winter, reduce the frequency. Older, established trees cope with longer gaps between waterings but still benefit from deep watering in hot spells.

Guava tolerates more variation than mango, but both dislike waterlogged soil.

What soil do mango and guava need?

Soil that drains freely but holds some nutrients. UAE sand drains fast and is low in organic matter, and some soils are saline, so dig a generous hole and mix compost in. Water deeply to carry salts past the roots. In pots, use a quality potting mix with perlite and drainage holes.

How should you feed them?

Feed through the growing season with a balanced fertiliser, plus compost or manure worked into the soil surface in spring. Mango in particular benefits from regular feeding when young. Yellowing between the veins can mean a micronutrient shortage, such as iron or zinc.

Can you grow mango or guava in a pot on a terrace?

Guava can live in a large pot for years, with regular watering and feeding. A mango can start in a big container, but it is a large tree and needs the ground in the long run. Use a heavy pot with drainage holes, and check balcony weight rules.

Our outdoor plants range includes the Mango Tree, Guava and Guava Pakistan.

How and when do you prune mango and guava?

For mango, prune lightly after harvest. Remove dead and crossing branches and tip-prune to keep the size under control. For guava, prune in late winter or after fruiting to keep it bushy and manageable. Avoid heavy cuts in the hottest months. For tall trees, see tree trimming.

Why are the leaves yellow or dropping?

• Overwatering or poor drainage: yellow leaves and leaf drop. Check that water drains.
• Underwatering: wilting and brown leaf tips in summer.
• Nutrient shortage: pale leaves with green veins. Feed regularly.
• Salt build-up: brown edges. Water deeply to flush it.
• Transplant shock: new trees may drop leaves and pause for a while.
• Cold nights: young mango trees are more sensitive and can lose leaves in a cold spell.

Why is my mango not flowering or fruiting?

Young trees often take a few years. Too much nitrogen, heavy pruning, stress from irregular watering or cold or windy weather at flowering time can also reduce flowering and fruit set. Do not expect a big crop from a young tree.

Which pests attack mango and guava?

• Mealybugs: white cottony patches on stems and fruit stalks. Wipe off with a soapy cloth and repeat.
• Scale insects: small bumps on stems. Scrub off gently.
• Aphids and whitefly: clusters or tiny flying insects on new growth. Rinse and repeat.
• Mango hoppers: small jumping insects that affect flowers.
• Fruit flies: they damage ripening fruit, particularly guava. Pick fruit when ripe and clear fallen fruit.

Persistent infestations are worth showing to a garden professional.

How big do they get?

Mango can become a large tree with a wide canopy, so give it space. Guava stays smaller, usually a large shrub or small tree, and responds well to pruning.

For help with feeding schedules and pruning, see garden maintenance, or set up automatic watering with irrigation system installation.
