What grows on a south-facing balcony

A south-facing balcony gets 6 or more hours of direct sun a day, so sun lovers do best there: rosemary, lavender, thyme, olive, sedum and succulents. Shade plants burn, and on the hottest summer days a few leafy crops can't take the heat. That's what Balcony Plants (balconyplants.co) picks for a south-facing balcony in a typical temperate city.

Watch the hot days

A sunny balcony can run up to about 12°C (22°F) above the forecast on a hot, still afternoon, by our model, and small pots heat up fastest. When a heatwave is coming, shade the pots before the sun hits them, not after.

Tomorrow your SW-facing balcony in Riyadh hits around 42–45°C between 12:00 and 17:00.

In danger: Basil, Tomato

Do this tonight

  1. 1Move behind the railing line for afternoon shade.
  2. 2Drape light cloth over the fruit side after 12:00. Flowers abort above ~32°C.
  3. 3Water at dawn, then again at dusk if the soil is dry a knuckle down.

Tomorrow's watering plan

Basil: Check a knuckle down and water deeply only if the top of the soil is dry. It wants water about every day.

Tomato: Check a knuckle down and water deeply only if the top of the soil is dry. It wants water about every day.

Peak heat lands around 14:00.

FAQ

What plants grow on a south-facing balcony?

Sun lovers do best: rosemary, lavender, thyme, oregano, olive, sedum and succulents. A south-facing balcony gets 6 or more hours of direct sun, which also suits geraniums, chili and, on a lower floor, tomatoes. Shade plants like hostas, ferns and fuchsias burn there.

What are the best plants for a hot, sunny balcony?

On a south or south-west balcony that bakes all afternoon, heat-tolerant plants in pots do best: rosemary, thyme, sage, olive, geraniums, and chili once it's warm. The trap is the pot, not the plant. Small containers on a hot floor overheat fast, so pick sun lovers and keep them off the hottest surface.

What potted plants like full sun and heat?

Mediterranean herbs (rosemary, thyme, sage, oregano, lavender), olive, succulents, sedum and aloe all thrive in full sun. For flowers, geraniums, portulaca, verbena, marigolds and petunias handle it well, and chili and eggplant crop best with this much sun. Use the biggest pot you can and water at the edges of the day.

Can I grow tomatoes on a south-facing balcony?

Yes, and it's one of the best places for them: they need 6 or more hours of direct sun to ripen, and a south-facing balcony gives that. The catch is height. From about the 4th floor up, the wind shreds tall tomato plants unless they're sheltered, so higher up, grow a compact variety in the middle of the floor or pick chili instead.

What shouldn't I grow on a south-facing balcony?

Shade plants (hostas, ivy, ferns, fuchsias, begonias, impatiens), which burn in all-day sun, and heat-sensitive leafy crops like spinach, rocket and pansies, which give up when summer peaks. Lettuce is a stretch here too.
