Making Plant Markers
I don't want to lie to you- this 'how-to' can only just count as so. It's primarily born from an excuse for me to play with my knife and be in the greenhouse, but I reckon that's as good a reason as any.
Better looking than a lollipop stick and free to boot, you can stick this stick in your seed trays and plant pots to identify what exactly is growing in there. We are partial round our house to planting unknown seeds and so have 'miscellaneous' plant markers as well as a 'perhaps peach?' stick or two (not one to discriminate, every plant qualifies for the handmade identifier...).
You'll need a small carving knife, a stick which is about a cm or so thick (X a whole bunch), a hand saw/shears and a biro (a sharpie, due to the greenwood, just won't do the job).
First off you'll need to forage for your sticks- if you can't find enough on the ground use your shears to pluck a suitably sized stick from your garden tree and the saw to cut them to size (make sure you are careful of fingers and thumbs doing this). Somewhere near one end of your stick and using your knife peel off an inch or so of bark. Keep going over this area till you have a space wide enough to write on (you could even get little people to help you out here using a peeler). At the other end you want to make a spike to go in to the soil- striking away from you, use you knife at an angle to get that sharp diagonal cut.
It's pretty simple. Just write on what you need and wahey- genuinely useful and handsome plant markers and a somewhat legitimate excuse to while away time in your greenhouse with a cuppa as Radio 4 hums in the background...
