Polokwane in January is 32 degrees and dropping. Tzaneen is humid. Musina is dry hot. The Lowveld bakes. The Bushveld glows. A traditional English garden in Limpopo is a war you're losing. A properly planted indigenous garden is one you barely have to fight.
Limpopo is the easiest province in South Africa to garden in, if you accept what the province is. Hot summers, mild winters (except the Highveld edge), and a long list of trees, shrubs, and grasses that evolved here. The traditional suburban garden of lawn and roses is a constant struggle. Indigenous is what stays tidy without you.
Indigenous Trees That Stay Tidy
The number one thing that drives Limpopo homeowners crazy is a tree that drops leaves, fruit, sticks, or seed pods all over the lawn. The traditional coral tree, the syringa, the wild fig: all beautiful, all messy. The replacement is a tree that holds its shape, doesn't drop much, and tolerates the climate.
A few good options:
- Dombeya rotundifolia. The wild pear. Evergreen, compact, white flower clusters in spring. The bees love it. The leaves stay on the tree.
- Combretum erythrophyllum. The bushveld willow. Semi-deciduous, but the leaf drop is brief. Lovely yellow autumn colour.
- Searsia (Rhus) species. The karee and the wild currant. Tough, evergreen, small. Perfect for the suburban garden.
- Olea europaea subsp. africana. The wild olive. Slow-growing, evergreen, eventually a beautiful shade tree.
- Bolusanthus speciosus. The tree wisteria. Magnificent purple flowers in spring. Deciduous but tidy.
- Erythrina abyssinica. The coral tree for small gardens. Brighter flowers than the common coral, less aggressive.
These trees do most of the work for you. Once they're established (a year of decent rain or supplementary watering), they don't need much. Prune lightly after flowering, water through the worst droughts, and stand back.
Native Shrubs That Hold Their Shape
The English garden shrubbery needs constant pinching. Indigenous shrubs generally don't. They're bred by the climate to grow to a natural shape, and they stop there.
A few to consider:
- Tephrosia. The silvery leaves, the pink flowers. A medium shrub that doesn't need much.
- Bauhinia. The pride of the Lowveld. Big, shrubby, with orchid-like flowers. Tidy.
- Dombeya. Smaller cultivars. Round, evergreen, low maintenance.
- Grewia. The raisin bush. Small, dense, with yellow flowers and edible berries.
- Plumbago. The Cape leadwort, but it grows well in Limpopo too. Blue or white flowers, evergreen, takes pruning.
- Hibiscus. The wild hibiscus species. Less showy than the tropical ones, far less work.
For a screen or a hedge, consider the wild seringa (Burkea africana), the silver cluster leaf (Terminalia sericea), or a row of spekboom (Portulacaria afra). All are evergreen, dense, and slow-growing. The slow growth is the point. Less to trim.
Reducing the Lawn
Lawn is the most water-hungry, labour-intensive part of any garden. In Limpopo, the cost of a lawn is measured in irrigation, mowing, edging, and fertilising. Reduce the lawn, reduce the work.
The replacement options:
- Ground covers. Dymondia, a hardy indigenous carpet, survives drought and walking. The lawn look without the mowing.
- Wild grass. The "no-mow" lawn mixes (Buchu dactylon and similar) grow to a set height and stop. A trim once a season.
- Mulched beds. The simplest. Bark, stone, or compost. Plants in groups, mulch between.
- Paving. For entertainment areas. Practical, low maintenance, integrates with the garden.
- Indigenous meadow. Spekboom, vygies, gazanias. Planted thickly, they cover the ground. A weeding session twice a year is enough.
The Low-Maintenance Calendar
A properly planted indigenous garden in Limpopo needs very little, but the little it needs is scheduled:
- January-March. Water deeply once a week if it hasn't rained. Watch for new weeds.
- April-May. Light pruning after the summer growth flush. Top up the mulch.
- June-July. The dry winter. Water young trees. Otherwise, leave the garden alone.
- August-September. Spring growth. A general feed (compost or slow-release organic). First mow of the no-mow lawn.
- October-November. Watch for pests. The aphid and scale explosions happen in early summer. A preventative spray on the roses.
- December. Mostly enjoy. The garden is doing its thing.
Plant Choices for the Toughest Spots
Limpopo gardens have a few impossible zones: the north-facing wall, the paving next to the pool, the strip between the driveway and the fence. Indigenous plants that handle these:
- Spekboom. The champion. Handles full sun, drought, frost (mild), and bad soil. Edible, fire-resistant.
- Agave. The century plant. Architectural, drought-resistant, evergreen. Watch the spines.
- Aloe. The tree aloe (Aloe ferox, Aloe marlothii) is huge and tough. The smaller aloes (Aloe arborescens) make a good screen.
- Vygies. The pigface. Ground cover, brilliant flowers, salt-tolerant.
- Bauhinia. The dwarf orchid tree. Smaller than the full-size version, great for a tough spot.
- Wild fig (Ficus). Slow-growing, evergreen, drought-tolerant. Don't plant it near the foundations.
Final Word
Limpopo is a generous province. The light is bright, the rain comes when it's needed, and the soil (in most areas) is good. The trick to a tidy garden is to plant what the province offers you, not what a garden centre in Johannesburg thinks you should have. Slow-growing trees, native shrubs, and as little lawn as you can get away with. The result is a garden that looks like it belongs here. Which, of course, it does.
