This seedling tracking system keeps track of all of your indoor seed sowing without the need for tags or markers for each plant.

Simple Way to Track Seedlings

This is a really simple way to keep track of the seeds you’ve started indoors without having to prepare plant tags or labels at sowing time.

Instead, you label your planting tray like a spreadsheet with rows and columns and use it over and over again.

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.
