New tool: a Vegetable, Herb & Fruit Planting Calendar that actually knows which region you're in

Seventh tool in the Farming section, and this one started from something that’s bugged me for a while: almost every planting calendar you find online is either written for the Northern Hemisphere, or it’s a single national list that quietly assumes South Africa has one climate.

It doesn’t. Gauteng and the rest of the summer-rainfall interior get frosty winters and plant in spring. The Western Cape is the reverse, wet mild winters, dry summers. The Northern Cape is dry and hot most of the year. The KwaZulu-Natal coast and the Mpumalanga/Limpopo lowveld barely see frost at all. Pick your province, and where it actually matters, which part of it, plus a month, and the tool shows vegetables, herbs and fruit for your real regional pattern, with an action (sow, start in trays, or transplant seedlings), an expected harvest month, and sun, water and difficulty ratings.

That second question matters more than it sounds. A few provinces genuinely span more than one climate, KwaZulu-Natal’s Durban coast is subtropical but its Midlands and Drakensberg towns get real frost, and Mpumalanga and Limpopo are mostly cool highveld except for their lowveld pockets, Hazyview, Nelspruit, Hoedspruit. Tap whichever description actually matches where you are and you get that pattern, not the province average. (This used to be a free-text town field. I dropped it, partly because it broke on iPhones, Safari’s autocomplete suggestion could cover the input while you typed, and partly because it was never really about the town, there’s no per-town data behind it, just these same regional patterns, so a direct tap-to-choose question is more honest about what the tool actually knows.)

Honest caveat on sourcing, since I’d rather say it upfront than have someone catch it: the vegetable months come from two real South African planting charts, not something generated. One province’s chart, though, had every warm-season crop landing in the middle of winter, which isn’t right anywhere in the country, so I dropped it rather than publish it, and instead let you pick directly between the other regions’ patterns for that province, whichever actually matches where you are. Herb windows aren’t from a chart at all, since nothing at that level of regional detail exists for herbs, they’re modelled from each herb’s known cool or warm season habit, and the tool says so rather than pretending it’s sourced the same way as the vegetables.

If you garden and this gets your month or region wrong, I’d genuinely like to know, that’s exactly the kind of thing worth fixing.

This is actually lekker useful, and it’s about time somebody said it out loud, SA is not one climate. My cousin in Polokwane and my mother in Kimberley cannot be planting on the same dates as us here in Soweto, it’s just not the same weather at all. I’ve seen those generic planting calendars before and they always confused me, like why is it telling me to plant tomatoes in a month that’s basically winter here.

This is the kind of tool that actually helps ordinary people save money too, not just farmers. With food prices the way they are, more township families are trying backyard veggies to cut grocery bills. If you could add something later showing which veggies grow well in small spaces or containers for us city people without big yards, that would be next level. How are you getting the regional data accurate though, is it based on rainfall zones or actual frost data?

Quick follow-up on this one: added a second mode today.

Until now the tool only answered “what can I plant this month”. If you already know you want to grow something, tomatoes say, and just want to know when, you had to page through months to find it. There’s now a toggle at the top, “When do I plant a specific crop?”, pick your crop from the dropdown and it shows a small calendar strip for your region: which months to sow, start in trays, or transplant, plus roughly when it’ll be ready.

Same underlying regional data as the month view, just organised the other way round, so the two can’t disagree with each other. A few crops genuinely don’t have a good window in a particular region, Melon in the Northern Cape’s dry interior is one, and it says so directly rather than showing an empty result.

Good question. It’s rainfall pattern first, summer rainfall vs winter rainfall, since that’s really what drives the whole calendar, and frost gets folded in as the reason winter goes quiet in the colder zones. Data’s from two real SA planting charts, not something I made up, it’s all in the FAQ on the page if you want the detail.

Container/small-space veggies for the backyard crowd is a solid shout. No promises on timing but noted.

Ja this is a good point about SA not being one climate, I say the same thing every time someone shares one of those UK gardening calendars on Facebook. I’m in the Western Cape so we’re winter rainfall, complete opposite of Soweto and the Karoo towns, and I learned that the hard way years back trying to grow veggies on someone else’s schedule.

Bit of practical advice from an old electrician who’s done a lot of DIY around the garden too, if you’re setting up irrigation timers for whatever you plant, get a decent weatherproof enclosure for the controller and don’t skimp on the cable joins, water and cheap connectors are a nightmare combination. Rather solder and heatshrink or use proper waterproof gel connectors, I’ve fixed too many corroded irrigation valves that cost someone a fortune in wasted water.

Good that the data’s from real SA charts and not just guessed. Will have a look at the container veggie bit, we’ve got a small stand here and I’m forever fighting the wind with anything in pots.
