March – Growing season is starting

March – Growing season is starting:

In this series I will tell you what we are doing on our balcony month by month.
The goal is that you can achieve a nice balcony garden, that provides you with food and joy.

After a long and cold winter, spring is finally around the corner.
The temperatures are rising and the little seedlings are growing. Depending on the temperature, first plants can already go outside. Spring has arrived!

Getting Started

Read below what we did this month:

  • Plant your seedling
    If you didn’t start your seedlings yet, you should start. Especially seeds that take longer for germination (tomatoes, zucchini, cucumbers).
    It is important, that the days are already longer and the plants get light. If this is not possible, please check out our tutorial on building your own growing lights: Make your own LED growing light – with Arduino and WS2812B lights
  • Moving your seedlings outside
    By the end of March, you can plant your seedlings outside. You take the little seedlings and divide them into the outside pots and boxes. You need to give every little plant enough space. Once you plant them outside, they need a lot of water and light.
    Should there be another cold-wave appearing, you can cover the little plants with dry leaves or fleece that you can buy in a garden store. This will keep the little plants warm and alive.
  • Pre-sprouting potatoes
    Potatoes should be pre-spouted before planting on the balcony. This is done very easily. You just take some potatoes that you have laying around at home for this process. It doesn´t matter if they already have green spots or started to sprout.
    You can take an egg carton and fill every spot with a potato. Leave the potatoes in the light by room temperature.
  • Directly planting outside
    End of March some seeds can be planted directly outside. Be careful, that the freezing temperatures are already over in your area.
    Plants that can be planted directly outside are: peas, beans, carrots, spinach, etc.
  • Preparing pots
    Your seedlings will go out in a few weeks. Therefore, you should already think about the space they require. Pots can already be filled with soil and fertilizer.
    Depending on how many of your seed germinated, you might need to buy or build new planting pots and boxes. This will take time and should be done already in March.


In early spring the preparations are important.
Once the seedlings can go outside, everything on the balcony should be ready for them.
