First of all, plant your vegetable garden
Before you start sowing vegetable seeds, it is important to plant the vegetable garden. Ask yourself these simple questions:
"What vegetables do I want to sow and eat?"
"Do I have enough space for these vegetables?"
"How are the weather conditions like on my balcony/ in my garden?"
I always make a list of the vegetables I want to sow and then measure out the space in my garden. You can also create extra space in your garden with flower pots.
Altogether you can divide the vegetables into three different categories: low feeders, medium feeders and heavy feeders.
Heavy feeder vegetables are cucumbers, zucchinis, tomatoes, peppers, potatoes, eggplants etc.
These vegetables require more space in the bed and more nutrients than medium and low feeder vegetables.
A list of the categories can be seen below:
You can then start planning your vegetables, with for example a planting calendar. If you google it, you can find free calendars on the internet. It's also important to know which vegetables can coexist on the raised beds and which ones don't get along - otherwise they'll grow poorly or get lots of plant diseases.
I have created my list using an Excel spreadsheet. The link to my spreadsheet is just below.
