How to Take Care of Pepper Trees in South Africa

Pepper trees are a familiar sight across South Africa, from driveways lined with feathery canopies to farm gardens bursting with red berries.

The two most common types are the Peruvian pepper tree (Schinus molle) and the Brazilian pepper tree (Schinus terebinthifolia).

Both are fast-growing, drought-tolerant, and beautifully ornamental, but they can quickly become messy or invasive if not cared for properly.

Here’s how to keep them healthy, safe, and well-shaped for years to come.

1. Watering Your Pepper Tree

Pepper trees are hardy once established but still need deep watering in their first few years, especially during South Africa’s hot, dry summer months.

How to water correctly:

• Water deeply once or twice a week rather than frequent light watering.

• Allow the top layer of soil to dry slightly between sessions.

• Avoid waterlogging, standing water can cause root rot.

  
  

Once mature, they can handle long dry periods, but young trees will drop leaves or thin out quickly if neglected during drought.

2. The Right Soil for Pepper Trees

Pepper trees prefer well-drained, organically rich soil. In heavy clay soils, water sits around the roots too long, a recipe for stress and disease.

To improve your soil:

• Mix compost or well-rotted manure into the top 30 cm before planting.

• Add coarse sand or bark chips for better drainage.

• Use natural soil ferments like JMS (Jadam Microorganism Solution) to boost microbial life and nutrient cycling, ideal for poor or compacted soils.

Pepper trees can adapt to most South African soils, from sandy coastal types to red inland loam, as long as water can move through easily.

3. Fertilising for Steady Growth

Feed pepper trees lightly, too much fertiliser encourages soft, weak growth and excessive berry production.

In early spring, apply a balanced fertiliser such as 10-10-10 or a slow-release organic mix around the dripline. Water well afterward. Repeat once in mid-summer if the tree looks pale or under stress.

If your soil is rich in compost, you can skip fertilising altogether, these trees are naturally resilient and don’t need constant feeding.

4. Pruning: Keep the Shape, Not the Size

Pruning pepper trees is more about guiding growth than controlling it.

These trees respond poorly to heavy topping, it ruins their natural shape and triggers messy, fast regrowth.

Best time to prune: late winter to early spring, just before new growth starts.

How to prune properly:

• Remove dead, diseased, or rubbing branches first.

• Thin out crowded interior growth to allow air and light through the canopy.

• Shorten or redirect any branches growing at awkward angles.

• Avoid topping. Instead, reduce height gradually over a few seasons if needed.

If your pepper tree is close to structures or power lines, it’s best to have a professional arborist handle the reduction.

Their root and branch systems can be unpredictable under stress.

5. Common Pepper Tree Problems

• Surface roots: These can lift paving and walls over time. Keep large trees at least 3–5 metres from structures.

• Invasiveness: Both species self-seed easily. Remove unwanted seedlings early before they take hold.

• Sap and berries: Can be messy on paving, prune low-hanging branches if needed to reduce drop zones.

In Summary

Pepper trees are tough, beautiful, and iconic across South Africa. With a little routine pruning, smart watering, and the right soil preparation, they’ll stay healthy and add character to your garden for decades.

If you’re unsure whether your pepper tree needs pruning or removal, or if roots are starting to cause damage, get professional advice before acting.
