Quick answer: There is no final statutory plant-count limit in force that readers should treat as settled law. The February 2026 draft regulations propose five cannabis plants per adult in a private place, but the Ministry says the limits still require finalisation and parliamentary approval.
The questions “How many cannabis plants can I grow in South Africa?” and “How many weed plants can you grow in SA?” are often answered with “four plants”. That figure should not be presented as current law.
The current private-cultivation position
The Constitutional Court protects cultivation by an adult in a private place for personal consumption in private. The Cannabis for Private Purposes Act 7 of 2024 creates a future statutory framework, but commencement is still listed as “to be proclaimed”.
The Constitutional Court did not set a fixed number of plants. That is why a widely repeated “four plants” answer is not a safe summary of the current position.
What the 2026 draft proposes
The February 2026 draft regulations propose a maximum of five cannabis plants per adult at any given time in a private place, regardless of plant size, shape or strain.
The Justice Ministry's statement is equally important: the limits are proposals and will be submitted to Parliament for approval only after the regulations are finalised.
| Claim | Status as of 30 July 2026 |
|---|---|
| Four plants per adult | Do not present as settled current law. |
| Five plants per adult | Proposed in the 2026 draft; not yet final. |
| Private adult cultivation | Protected when genuinely private and for personal consumption. |
| Commercial cultivation or sale | Not authorised by the private-use judgment. |
Why a plant count is not the same as a legal harvest amount
Plant size, genetics, training, season and indoor conditions can produce very different harvests from the same number of plants. The draft therefore separates the proposed plant limit from proposed possession and transport limits. A plant count should never be treated as permission to sell the harvest.
Per adult, per household or per property?
The draft wording says five plants per adult at any given time. Shared homes can create practical questions about ownership, control, access and total possession. Until the final regulations are published, do not assume that multiplying five by the number of adults resolves every shared-household scenario.
