Fungus diseases and pests to look out for this coming spring in South Africa and Namibia

When it’s time to ring in spring, you will need to ramp up your garden care routines to prepare for common fungus diseases and pests. While this seasonal shift is experienced differently for the various regions of South Africa and Namibia, there will be some common factors to look out for. We break down concerns by region and which solutions to apply to keep your garden in good stead.

Biomes of South Africa and Namibia

To better understand the region and the common traits where you live, we have organised our information by biomes.

A biome is a large naturally occurring community of flora and fauna occupying a major habitat. These groupings can be split into nine main biomes but can be further divided into about 20 biomes. The reason for this is that, for example, not all forests are the same. When comparing temperate forests to tropical forests, these are vastly different spaces that will experience different pests and fungal diseases.

To see what biome you live in, explore this interactive map. And for readers based in South Africa, read our guide on spring climate zones.

South Africa’s Biomes

Terrestrial biomes: Albany thicket, Azonal vegetation, Desert, Forests, Fynbos, Grassland, IO Coastal Belt, Nama-Karoo, Savanna, and Succulent Karoo.

Namibia’s Biomes
