This is a really simple way to keep track of the seeds you’ve started indoors without having to prepare plant tags or labels each time you plant. Instead, you label your planting tray like a spreadsheet with rows and columns and use it over and over again.
You can find all of my seed starting tips here.
Here’s a short video demonstration:
- I use 10×20″ trays. My local garden nursery gives away any trays and pots that customers return to them (and they recycle the rest), so I get what I need each spring.
- A 4-cell 2″ soil blocking tool works perfectly with this size of tray. One tray holds 50 (2″) soil blocks.
- Permanent marker.
- Using a permanent marker, label your tray in rows and columns, just like a spreadsheet.
- Each tray gets a unique number (for example: Tray #1).
- A 10×20″ tray accommodates 5 rows (named A to E) and 10 columns (named 1 to 10).
- I keep notes on everything I plant so I can monitor which seeds are most successful at harvest time.
Using this labelled tray system, I note the seed name and source, the tray number, and which cells the seeds were planted in (from A1 to E10).
For example, if I plant 5 broccoli seeds in blocks A1, B1, C1, D1, and E1, my note would look like this:
That’s it! Easy.
