Growing potatoes in a Planty Garden
Can you grow potatoes in a garden box?
But I still wanted to experiment. So, I got some ideas off the internet and tried growing potatoes inside and outside of my garden boxes.
One year, I spent a week building a beautiful box for my potatoes and filled it with tons of potting soil. Then I forgot to water it.
Another time, I planted potatoes in my garden box but let their neighbors overshadow them. Others I simply forgot to harvest. Then I found them again in the spring: completely rotten.
Adding an extra level
And yes: I managed to harvest a few potatoes that way.
40 or 20 cm deep?
And guess what? The results were exactly the same.
The plants did equally well in all 4 patches. And the yield was no different either: about 1.5 kg per square patch.
So, there's no need for an extra box on top.
Harvest per m2
So, compared to that, my harvest is gigantic.
You can harvest even more from an MM-Mini: between 1.5 and 2 kg.
Almost 5x as much harvest
This soil mix gives potatoes exactly what they need: nutrients, moisture, and airy soil that drains well.
So, it pays off. And if you run out of space, you can grow more potatoes in an MM-Mini:
When should you plant potatoes?
There are early and late varieties, but I don't keep track of that. I plant whatever potatoes I have whenever I have time.
Usually, I'll just grab a few small ones from my mom's garden box. In April, they'll sprout spontaneously on their own. But you can also get special seed potatoes from your local garden center in early March.
Hoe poot je de aardappeltjes?
Plant them as deep as you can: at the very bottom of your garden box.
The plants grow about 40 to 50 cm tall, so use square patches in the middle of your garden box.
Or, use a whole garden box and fill it up:
How do you care for your potato plants?
Water regularly and make sure the plants aren't in the shade. The potatoes need a lot of sunlight.
That's all there is to it.
If you like, you can give the plants some support by placing a mini-trellis made from coarse mesh garden wire over them.
If you're aiming for larger potatoes, wait and dig them up when the stems and leaves turn yellow and die. That only happens in July or August.
Plus, it's really fun to harvest potatoes by hand. I always feel like I'm digging for buried treasure.
The entire plants turn black and the potatoes turn brown. Or sometimes the affected area is so small, you might not notice it. Either way, there are pathogens in the soil mix. They'll eventually disappear on their own, but it can take 2 to 3 years.
If you put plant potatoes in the same area within those 2 to 3 years, the disease will strike mercilessly. It won't just affect your potatoes, but your tomatoes too.
Keep your garden boxes healthy
So if you want to grow potatoes every year, you'll need at least 4 garden boxes.
But again: your extra effort will be rewarded:
