Choosing the right tree for your garden is mostly a matter of honest questions: how much room you really have, what your soil and wind are like, and what job the tree has to do. Get those answers right and a tree becomes the best feature of the property. Get them wrong and you inherit decades of pruning, lifted paving and thirsty beds.
We are a tree felling company, so we do not plant trees or run a nursery. What we do see, again and again, is what happens when a tree was planted in the wrong spot. This guide shares what that work teaches. For the final species choice, a good local nursery or an arborist is the right person to ask.
Choosing the right tree for your garden starts with the job
Decide what the tree is for before you look at a single sapling. Shade over a north-facing patio calls for a broad deciduous canopy that lets the winter sun through. Privacy from a double-storey neighbour needs dense evergreen growth. A windbreak against the southeaster has to be flexible, and salt-tolerant if you are near the coast. Fruit, birdlife and autumn colour each point to different species.
Write the job down in one sentence. When a nursery assistant shows you something lovely that does not do that job, the sentence keeps you honest.
Think about the tree you will have in twenty years
The sapling in the bag is not the tree you will live with. Ask for the mature height and the spread of the canopy, then compare it with your plot. A tree that finishes at 15 metres does not belong on a small suburban erf, however charming it looks at the nursery.
As a rough guide, we think of small trees as under 5 m, medium trees as 5 to 10 m and large trees as over 10 m. Keep large trees at least 4 to 5 metres from walls, pools, paving and sewer lines, and give small trees a little less. Roots follow water and soft ground, so a pool or a leaking pipe is a magnet. Our article on tree roots damaging walls and paving shows what that looks like once it has gone wrong.
Indigenous trees that suit Cape Town gardens
Trees that grew up with the Cape’s wet winters and long dry summers establish quickly, need modest watering once settled, and cope with storms that snap brittle exotics. Most also feed local birds and insects. These are five that nurseries commonly stock and that we rarely have to remove:
| Tree | Mature height | Good for |
|---|---|---|
| Tree fuchsia (Halleria lucida) | 3 to 6 m | Small gardens, sunbirds, screening |
| Wild olive (Olea europaea subsp. africana) | 5 to 10 m | Tough evergreen shade, wind hardy, good for birds |
| Keurboom (Virgilia oroboides) | 6 to 10 m | Fast screening and spring blossom, but short-lived |
| Water berry (Syzygium cordatum) | 8 to 12 m | Damp spots and pond edges |
| Cape ash (Ekebergia capensis) | 10 to 15 m | Large shade tree for bigger plots |
Fruit trees are worth considering too. Figs, citrus and olives cope well with our climate if they get sun, shelter from the southeaster and decent summer watering.
Trees that tend to become problems
A large share of our tree removal work involves the same few species, usually planted too close to something. Gums drop heavy limbs in the southeaster. Pines grow far bigger than people expect and become a fire concern. Poplars send suckering roots into drains. Rubber trees and ficus planted a metre from a wall lift paving and crack foundations.
Several gum, pine and poplar species are also declared invasive aliens in South Africa, so there can be rules on planting and controlling them. Ask the nursery directly whether a species is listed before you buy it.
Palms deserve a mention. They look tidy and take little space, but they are not maintenance-free: old fronds and seed heads build up and need clearing. If you want one, plan for periodic palm cleaning, which is done by climbing, not from a ladder.
Check the rules before you plant or cut
Planting a milkwood or a real yellowwood is a lovely choice, but plant it where it can stay. Both are nationally protected, so if one ever has to come out or be cut back hard, you will need a licence first. The tree on the pavement outside is a different case again: it belongs to the municipality, so it is not yours to plant over, prune or remove.
If you are buying a house with a mature tree, find out which category it falls into before you plan around it.
Get it planted well
This is where a nursery earns its fee. In general, they will tell you to plant in autumn or early winter so the rains establish the roots before the first hot, windy summer. They will suggest a hole two to three times the width of the root ball rather than a deep narrow pit, loose stakes with soft ties against the wind, and a thick ring of mulch.
Deep watering through the first two summers builds drought resilience, and light formative pruning early on prevents the weak forks that fail in storms decades later.
If the tree is valuable or the site is awkward, an arborist can advise on species and placement before you commit.
When the wrong tree is already there
Sometimes the honest answer is that the existing tree will never suit the site. Replacing it is not a defeat, it is how gardens improve. Our team climbs and takes big trees down in sections, which is how we work near houses, pools and boundary walls in older gardens such as Constantia. We then grind the stump, so the ground is ready for whatever you choose next, and we take the waste away as part of the job.
Removal is far easier to deal with while a tree is still small, so do not wait for it to grow into the problem. We are fully insured, and the site visit and written quote are free. To get one, WhatsApp a photo to 071 799 1993 or use our contact page.
