These handy dandy Crew Stem Soil Pins are available in green and original red > from as little as 15 cents each. Grab a 10 pack for $1.70 or save with a 20 pack for $3 :)

Use these to pin down stems and cuttings, keeping nodes in contact with soil to get those roots growing. I love these for pushing stems in contact with moss poles too, both to secure them and to encourage aerial roots to get growing. Also called soil pins, soil clips, stem forks, soil forks or stem clips. These come in packs of 10 and the green are slightly smaller than the original red stem clips (size below and in the photos).

The pull tab sticks up just enough above the soil surface to easily grab and pull out once the stem has rooted, ready to re-use, again and again. Made of sturdy plastic with a little bit of flex. The pull tab also means you don't damage delicate stems or new roots when removing the pin later.

Size:

These come in packs of 10 or 20. Each pin measures just under 4.5cms long, by 1cms wide. The tab on top measures 1cm and it goes up to 3.4cms deep into the soil to hold even stubborn stems securely in place. 

Lots of uses:

Curl stems back on top and pin down your 'String of....' and 'Chain of...' so the nodes stay in touch with the soil on top and start growing again. Great method when stems are green and growing at the ends but the roots are bare or stringy. 

Pin down stems of vining epiphytes with aerial roots, filling in bare patches to create a fuller, more lush plant. Popular method with vining plants like Pothos, Epipremnum and Philodendron (Neon Pothos shown in the photos).

Pin down cut stems for soil propagation, encouraging root growth where nodes touch the soil. Especially popular with longer stems with closely-spaced nodes, such as String of Turtles and String of Pearls. Also popular when propagating using the butterfly method for Chain of Hearts.

As a form of air layering to propagate without cutting. Pin down a node onto the soil surface without cutting it off the mother plant. Wait for roots to grow, then trim off the already rooted plant. A faster, more successful method than soil propagation for many epiphytic plants with aerial roots. 

Use with moss poles to keep nodes in touch with substrate, encouraging aerial roots to grow into your new support pole and securing stems to the pole until they hold on themselves.
