April 26, 2026 • Soshanguve, Pretoria"After weeks of preparation — clearing, turning, building, and mulching — the moment finally arrives: the first seed goes into the ground. It's not just planting. It's the culmination of every decision made so far. And watching that first garlic clove disappear into the soil, I knew the system was finally alive."
Growing Food in Soshanguve (Part 6): The Software Upload — Planting Garlic
There's a moment that every gardener waits for. It's not the day you start. It's not the day you finish the beds. It's the day you put the first seed or clove into the ground.
For me, that moment came on the morning of April 26, 2026. The sun was still low, the air was cool, and the garden was finally ready. After weeks of clearing, turning, building, and mulching, I was about to do the thing that made all the work worthwhile: I was planting.
Over the last five posts, I've documented the entire process of transforming an overgrown piece of land into a productive growing system. We cleared the invasive weeds in Part 2. We turned the soil and removed persistent roots in Part 3. We built permanent raised beds in Part 4. And we installed the mulch firewall in Part 5. Each step was preparation for this moment.
Now, the system was stable. The hardware was built. The firewall was in place. And it was time for the software upload — the first planting.
I chose garlic as the first crop for a few reasons. It's hardy and forgiving — an ideal crop for a new system. It's high-value and stores well. And perhaps most importantly, garlic is a natural pest repellent. By planting it first, I was essentially inoculating the garden against some of the pests that would otherwise attack later crops.
But choosing garlic was only the first decision. There were many more to make: where to source the cloves, how to prepare them, how to plant through the mulch, how to space them, and how to track their progress. In this post, I'll document every step of that process — the decisions, the mistakes, and the lessons learned.
1. The Source: Where I Got the Cloves
Close-up of the sprouted cloves. The green shoots and root nubs tell me they're ready to grow.
The first and most important decision was sourcing the garlic cloves. This might sound simple — just buy some garlic from the shop and plant it, right? That's what I used to think. But I learned the hard way that supermarket garlic is often treated with sprout inhibitors, making it nearly useless for planting.
Here's what I look for now:
- Firmness: The clove should be firm to the touch. Soft or spongy cloves are already rotting.
- Shoot development: I prefer cloves that have already started sprouting — a green tip emerging means the clove is alive and ready to grow. In my experience, sprouted cloves emerge 3–5 days faster than unsprouted ones.
- Variety: I use locally grown varieties like 'Cape Town Pink' or 'Transylvanian.' They're adapted to our climate and have proven reliable in Gauteng conditions.
- Source: I buy from local farmers or seed suppliers. Never from a supermarket. The imported stuff is often treated and fails to perform.
For this planting, I sourced my cloves from a local farmer in the Soshanguve area. The cloves were firm, sprouted, and free of disease. I inspected each clove individually before planting, discarding any that were soft or damaged.
I made one mistake during sourcing: I didn't ask about the mother bulb's health. After planting, I noticed some of the cloves came from bulbs that had started to separate prematurely. That doesn't necessarily mean they're bad, but it could indicate stress during storage. I'll be more careful about that next time.
By using sprouted cloves, I reduced the "initialization time." These cloves had already passed dormancy and were ready to interface with the soil biology immediately upon planting. In my side-by-side test, sprouted cloves emerged in 7 days; unsprouted cloves took 12–14 days.
2. The Planting: Through the Firewall
Pulling back the mulch to plant. The soil underneath was moist and crumbly — exactly what the garlic wanted.
As I explained in Part 5, I don't remove the mulch to plant. Instead, I "patch" it. The technique is simple but precise.
Step 1: Pull back the mulch.
I reached into the bed and pulled the dry grass and straw aside, creating a small opening in the armor layer. Underneath, the soil was moist and dark — the mulch had done its job. I could smell the earth — that rich, organic scent that tells you the biology is active.
Step 2: Make the hole.
Using a small hand trowel, I dug a hole about 5 centimeters deep. This depth is important: garlic planted deeper than 7 centimeters can rot, while shallower than 3 centimeters risks frost heaving the clove out of the ground during winter.
I made a mistake on the first few holes. I dug them too deep — nearly 8 centimeters. I had to pull the cloves back up and re-dig shallower holes. This is the kind of mistake that adds time but teaches you to pay attention to every detail.
Step 3: Insert the clove.
I placed each clove with the root end down and the shoot end up. This matters: upside-down cloves may still grow, but they waste energy turning themselves around. In my experience, that can reduce bulb size by 30% or more.
Step 4: Cover and replace.
I covered each clove with soil, then gently tucked the mulch back around the planting site, leaving just the green tip visible. The mulch acts as a thermal regulator — in Soshanguve, April nights can drop to 10°C while days hit 28°C. Bare soil fluctuates 15°C; mulched soil varies only 5°C. That stability reduces shock and gives the garlic a smoother start.
Step 5: Water in.
I gave each planted clove a gentle watering. The water settled the soil around the clove, creating good contact between the root end and the soil particles. After that, the mulch would do the rest — holding moisture, regulating temperature, and suppressing weeds.
Pro tip from the field: When planting through mulch, make sure the hole is wide enough to accommodate the clove without crushing it. I found that using my fingers to widen the hole — rather than just the trowel — gave the clove more room and reduced the risk of damage.
3. The Spacing: Why It Matters
Spacing is one of those things that seems simple but has real consequences. Plant too close, and the garlic will compete for nutrients and space. Plant too far apart, and you're wasting valuable garden area.
After researching and learning from previous seasons, I settled on this spacing:
- Plant-to-plant spacing: 10 centimeters apart.
- Row-to-row spacing: 20 centimeters apart.
- Root zone per clove: Approximately 80 square centimeters.
Why these numbers? Because garlic is a heavy feeder. If you space it too tightly, the bulbs will be smaller. I've seen spacing of 5 centimeters result in bulbs half the size of those at 10 centimeters. The trade-off is that closer spacing gives you more bulbs per square meter — but smaller bulbs. For me, the trade-off isn't worth it. I'd rather have fewer, larger bulbs.
I learned this lesson the hard way. In a previous garden, I planted garlic at 7-centimeter spacing. The bulbs that emerged were small — barely bigger than a ping-pong ball. I spent hours peeling and chopping those tiny bulbs, regretting every extra centimeter I had saved. Now I give them space.
In my previous garden, garlic spaced at 7cm produced bulbs averaging 3.5cm diameter. At 10cm spacing, bulbs averaged 5.5cm diameter. That's a 57% increase in bulb size. The extra space is worth it.
4. The 7-Day Audit
One week after planting, on May 3, 2026, I conducted a system audit. I walked through the garden, checked each clove, and recorded what I saw.
Emergence Success
Within 7 days, the green shoots had extended past the mulch layer. They were utilizing the moisture trapped by the firewall to power rapid leaf development.
Grid Consistency
The beds showed uniform emergence across the rows. This indicated that the soil architecture provided a consistent nutrient and moisture profile for every clove in the system.
What I found:
- Emergence rate: 95% (40 out of 42 cloves had emerged).
- Failures: 2 cloves failed to emerge (5%). When I checked, I found they had rotted in the ground. The cause appeared to be a small pocket of compacted clay that retained too much water after a light rain — classic "wet feet" syndrome.
- Lesson: Even a well-prepared bed has micro-variations. I marked that zone for future amendment with extra coarse sand.
I also measured soil temperature and moisture at 5 centimeters depth. The results confirmed what I had observed: the mulch was doing its job. The soil temperature at peak afternoon was 22°C, compared to 31°C on bare soil nearby. The moisture level was 18-20%, compared to 9% on the bare soil.
The audit also revealed something unexpected: garlic is already releasing low levels of allicin into the surrounding soil. Allicin is a natural biofumigant — it suppresses soil-borne fungi like fusarium and rhizoctonia. In other words, the garlic wasn't just growing; it was improving the soil for the next crop.
The garlic is already releasing low levels of allicin into the surrounding soil — a natural biofumigant. This suppresses soil-borne fungi and nematodes. Garlic isn't just a crop; it's a soil sanitizer for the next rotation. This is one reason I planted it first — to clean the soil before planting more sensitive crops.
5. Mistakes I Made
No planting is perfect. Here are the mistakes I made and what I learned from them:
Mistake #1: I planted on a windy day.
April 26 was windy. By the time I finished planting, the mulch had shifted on a few beds, and the soil had started to dry out. I had to go back and re-water those sections. Next time, I'll plant on a calm day, or water immediately after planting to settle everything.
Mistake #2: I didn't label the rows clearly.
I marked the rows with sticks, but the wind blew some of them over. By the end of the week, I wasn't entirely sure which rows I had planted and which were still bare. I had to walk through the beds and check each one manually. Next time, I'll use permanent markers or metal tags.
Mistake #3: I left a few cloves exposed.
In my haste, I didn't cover a few cloves properly. When I checked the audit, I noticed their tips were drying out. I tucked them back in, but it was a reminder to be thorough. Planting is not a race.
Mistake #4: I didn't check the cloves for disease.
Some of the cloves I planted had small brown spots on them. I didn't think much of it at the time, but after the audit, one of those cloves failed to emerge. I suspect it was diseased. Next time, I'll be more thorough in my selection.
6. The Long View: Garlic Takes Time
Garlic is not a quick crop. It takes 8–9 months to mature here in Pretoria. I won't harvest until December. That means this bed must survive the dry winter (June–August) with almost no rain, plus the spring winds that can desiccate leaves.
The mulch will be critical during that time. But around September, I'll add another layer of straw as a thermal blanket to reflect heat and retain soil moisture through the windiest months. Think of it as a firmware update to the firewall.
Here's what I expect to happen over the next 8 months:
This timeline reminds me that gardening is not about instant gratification. It's about patience, observation, and trust in the system. The clove I planted on April 26 won't become a bulb until December. That's 8 months of waiting. But when I harvest that bulb, it will be the product of everything I've built — the clearing, the turning, the beds, the mulch, the planting, and the waiting.

7. What's Next: The Staging Environment
With the garlic in the ground, the system is now alive. But I'm not stopping there. The goal is to build a diverse, resilient system that produces multiple crops throughout the year.
The next step is planting Swiss chard seedlings. Chard is a perfect companion for garlic — it grows in the spaces between the garlic rows, makes use of the available space, and provides a continuous harvest of leaves while the garlic matures underground.
In Part 7 — The Staging Environment: Planting Swiss Chard, I'll cover:
- Seedling preparation: Hardening off chard seedlings for transplant.
- Planting through mulch: The same "patch" technique I used for garlic.
- Spacing and depth: Chard needs 30cm between plants and 45cm between rows.
- Integration with garlic: Planting chard in the gaps between garlic rows to maximize space.
- First irrigation: Settling the seedlings with room-temperature water.
The goal is to create a system where every plant serves a purpose — and where the whole is greater than the sum of its parts.
8. Final Thoughts
Standing in the garden on the evening of April 26, I looked at the beds. The mulch was in place. The cloves were in the ground. The water had soaked in. And for the first time, the garden felt like more than a project — it felt like a living system.
The garlic won't be ready until December. That's a long time to wait. But that's the nature of growing food — it happens on its own timeline, not yours. The best you can do is prepare the environment, put the seeds in the ground, and trust the process.
I've been documenting this journey from the beginning — the clearing, the turning, the beds, the mulch, and now the planting. It's been a lot of work. But every step has brought me closer to the goal: a productive, resilient, self-sustaining food system.
The garlic is in the ground. The system is alive. And the next chapter is just beginning.
