Newlands Spring Garden Guide

Newlands has one of the best gardening climates in Cape Town.
Thanks to its position on the eastern slopes of Table Mountain, it receives significantly more rainfall than many other suburbs, making spring (September–November) an ideal time for vigorous plant growth.

Gardening tips specifically for Newlands:

Refresh your soil
 Add a generous layer of compost to vegetable beds and ornamental borders.
 Mulch around plants to conserve moisture before the dry summer arrives.
 If you’re growing indigenous fynbos, avoid rich fertilisers—they thrive in nutrient-poor, acidic soils. (Cape Town Resources)

Plant for colour
Spring is an excellent time to plant:
 Agapanthus
 Pelargoniums (geraniums)
 African daisies (Osteospermum)
 Salvias
 Clivias (in shadier spots)
 Indigenous bulbs and vygies

TIP: These perform well in the Southern Suburbs and attract bees, butterflies, and sunbirds.

Take advantage of Newlands climate
Because Newlands is cooler and wetter than many parts of Cape Town:
 Ferns and hydrangeas thrive in shaded gardens.
 Camellias and azaleas enjoy the acidic soils common in the area.
 Woodland plants can often be grown successfully beneath mature trees.

Start your vegetable garden
September is a great time to sow or plant:
 Tomatoes
 Beans
 Cucumbers
 Pumpkin and squash
 Beetroot
 Carrots
 Lettuce
 Basil

TIP: Wait until nights are consistently mild before planting heat-loving crops like tomatoes outdoors.

Prune and tidy
 Remove frost- or wind-damaged growth.
 Lightly prune spring-flowering shrubs after flowering.
 Deadhead flowering plants to encourage more blooms.

Prepare for summer
Although spring is relatively moist in Newlands, Cape Town’s dry summer is approaching:
 Install or check drip irrigation.
 Water deeply but less frequently to encourage strong root systems.
 Mulch 5–8 cm deep to reduce evaporation.

Support local wildlife
Consider planting indigenous species such as:
 Proteas
 Leucadendrons
 Ericas
 Restios
 Buchu

TIP: These are well adapted to Cape Town’s climate and provide food and habitat for nectar-feeding birds and pollinators. Spring is one of the best times to establish them. 

Watch for pests
As temperatures rise, keep an eye out for:
 Aphids on roses and vegetables
 Snails and slugs after rain
 Caterpillars on brassicas

Inspect plants regularly so problems can be managed before they become severe.
With Newland’s fertile, well-watered environment, spring is also an ideal time to experiment with a mix of indigenous fynbos, woodland plants, and an edible garden—giving you colour, biodiversity, and fresh produce through the warmer months.

Newlands has a unique climate compared with much of Cape Town: cooler summers, higher rainfall, fertile soils, and many shaded gardens beneath mature trees. That means you can successfully grow both indigenous Cape plants and a wide range of vegetables, herbs, fruit, and ornamentals.

Bush beans – Reliable and productive full sun
Basil – Perfect companion for tomatoes full sun
Lemon tree – Performs very well in Newlands full sun
Blueberries – Thrive in acidic soil with irrigation morning sun

These plants are widely recommended for Cape Town gardens, and many indigenous species such as proteas, ericas, restios, agapanthus, pelargoniums, plumbago, and osteospermums are particularly well adapted to the local climate while supporting biodiversity.
