Cannabis in Spring: What the Season Changes

Pretoria turns purple every October when the jacarandas bloom, and somewhere between the flowers dropping on every pavement and the first properly warm weekend, three things quietly shift for anyone who grows, stores or just enjoys cannabis. Here's what spring changes, and what's worth doing about it.

Spring Is Legally Planting Season Now

If you're growing at home, and since 2018 you're legally allowed to, up to four flowering plants per adult in private, spring is when outdoor cultivation starts. South Africa's growing season runs opposite to the Northern Hemisphere, seedlings go in once the last frost risk has passed, generally September into October, with harvest landing around autumn the following year.

This is also, realistically, when a lot of first time growers are giving it a go for the first time now that it's properly legal rather than a legal grey area. A few basics worth knowing before seeds go in the ground: cannabis needs a spot with strong, mostly unobstructed sun, soil that drains well rather than holding water, and protection from the kind of late season frost that can still catch the Highveld off guard into early September. Full detail on what happens after harvest in [Curing and Storing Cannabis Properly].

Your Storage Setup Needs to Catch Up Too

Whatever worked through a dry Highveld winter, covered in [Dry Weed: Why It Happens and How to Fix It], probably needs adjusting once the air starts holding more moisture again. Spring's rising humidity, especially once the coast starts feeding wetter air inland, means jars that sat perfectly fine all winter can start trending toward the too moist end of the scale instead. Full troubleshooting for both directions in [Curing and Storing Cannabis Properly].

Coastal readers have the opposite seasonal rhythm to think about. Durban's humidity doesn't really have an off season, but spring storms do tend to push it up further, worth an extra check on your humidity pack around now.

Terpenes and the Spring Feeling

There's no hard science behind "spring strains" as a category, so let's not pretend otherwise. What is fair to say is that if you're after something that matches a brighter, more energetic mood, checking a Certificate of Analysis for a limonene or pinene dominant terpene profile is a more useful place to start than reaching for anything labelled sativa and hoping for the best, covered in full in [Cannabis Terpenes: The Real Reason Strains Feel Different]. If you're after the opposite, something calmer for whatever spring throws at you, myrcene or linalool dominant profiles are the better signal.

The Spring Clean Your Stash Needs

Jacaranda season is as good an excuse as any for a real inventory. Check what's been sitting since winter for texture and smell, since anything that dried out over those Highveld months is worth fixing rather than pushing through, covered in [Dry Weed: Why It Happens and How to Fix It]. Check your humidity packs, since the two way ones do wear out and stop correcting properly after enough cycles. And if anything in the back of the cupboard doesn't have a Certificate of Analysis you can locate, that's a good prompt to check what LekkerWeed's own tested range looks like this season instead, covered in full in [Why Lab Tested Cannabis Matters].

FAQ

When does outdoor cannabis growing season start in South Africa? Generally September into October, once the risk of late frost has passed, following the Southern Hemisphere's opposite growing calendar to the Northern Hemisphere.

Does spring humidity affect stored cannabis? Yes, noticeably in most parts of the country. Storage that worked through a dry winter can start trending too moist as spring humidity rises, worth rechecking your setup rather than assuming it's still calibrated correctly.

Are there actual sativa or energising "spring strains"? Not as a real scientific category. Terpene profile, specifically limonene or pinene dominant products, is a far more reliable way to aim for an energising feel than any seasonal marketing label.

How many cannabis plants can I legally grow at home in South Africa? Up to four flowering plants per adult in a private space, or eight per household with two or more adults, under the Cannabis for Private Purposes Act. Full detail in [Cannabis Laws in South Africa: What Is and Is Not Legal].

Is spring a good time to check if my stash has gone bad? As good a prompt as any. Texture, smell and your humidity pack's condition are all worth a quick check after a full season of temperature and humidity swings.
