Why the harvest drops off after a few years
Most people who start with vegetable growing experience real joy in the first years. The first lettuce from your own garden with tomatoes and cucumbers, the first feeling of a real harvest, completely without additives. And finally snacking on tomatoes without washing them. And then comes the moment, usually already in the third year, where suddenly something is no longer right. The cucumber gets sick every year anew. The cabbage is eaten by pests, even though you treat it exactly the same as before. The soil seems tired, the harvests become smaller, even though you are putting in more effort than ever before.
That's not bad luck. It's a concrete, solvable problem, and almost always it has the same origin. When the same plant family comes to the same growing area year after year, it specifically draws certain nutrients from the soil. This attracts the same pests and pathogens every year, which settle in your soil because they always find the same food there. This soil fatigue is not caused by poor soil, but by wrong planning. The tricky thing about it is that you can't see the problem at first. Once nasty diseases are in your soil, they can stay there for up to 20 years. And then it is quite possible that you give up this beautiful hobby because you only have trouble.

Beds, plant species and years all at once in your head
To prevent this from happening to you, pay attention to planting breaks. Some crops need not just one year, but sometimes a rest period of up to five years before they can be planted on the same growing area again. If you observe the planting breaks, a sequence is created in which you are allowed to plant your plants in the soil. This sequence is called crop rotation, and its practical implementation is called rotation. This is not secret knowledge. It is practical gardening knowledge that has existed for decades. But it is complex and individual, and it is difficult to keep in mind when you have to oversee five beds, 20 plant species and several years all at once. You can acquire the necessary gardening knowledge through books and videos. In practice, however, it is very easy to lose track very quickly.
What GrowSimply does for you
Or you can get some help. Because GrowSimply solves this complex problem. This solution is for you if you want to grow your own vegetables sustainably and in the long term, without having to create new growing plans yourself every year. Because a sustainable growing plan is the foundation for sustainable vegetable growing. And the app makes it very easy for you to do everything right. It knows which plant families there are, which sequences work, which planting breaks are necessary and how you can implement this across all coming years on your growing areas. To do this, you only enter your growing areas once, select the plants you want to grow, and the app handles the calculations and later the management for all coming years. With GrowSimply, you avoid critical mistakes in crop rotation, planting times and planting breaks—exactly the mistakes that would otherwise cost you entire harvests. GrowSimply prevents these nasty mistakes for you fully automatically.
My motivation
Eating well and healthily
Being outdoors
My motivation is that of a gardener: saving money, eating well and healthy, and being outdoors. GrowSimply was developed by a single person: me, Thomas. I really enjoy working for you and love exchanging ideas with you. Software development is complex in itself. But I also have to handle many other tasks that don't actually have much to do with the app anymore. Developing it further is what I love doing most and how everything started.
Who Sellerina is
So that it doesn’t all become too much for me, I developed Sellerina: my digital assistant. As a cartoon character, she introduces you to vegetable plants and explains what you should pay attention to. I have invested many hundreds of hours of work in “Sellerina”. Her videos are made with the help of AI and allow me to share information with you in a charming way and to gain a little visibility in the “black hole” called “the internet”. At the same time, this is the only way my high productivity is possible. So I can offer you good content and still invest enough time in developing this app further.
From hobby to app
GrowSimply started as a hobby. I only released it when Gesa wanted to film a video with me. That was the impetus to try at all and to earn my living with it.

In conversation with Gesa:
“...with the app, I clearly have almost no downtime in the beds.”
