Besgrow's tagline is 'At the root of healthier plants' and it certainly is. This is for a super-compact brick of Besgrow Dry Spagmoss that measures about 23cm x 12cm x 9cm. Besgrow naturally air dries their moss for maximum water holding capacity. One brick makes up to 12 litres once hydrated. Easy to prep (see below). Very compact so you get way more than you think.

How do you prep dry sphagnum moss?

Give it a good soak in water and you're ready to go. Soak in warm water for best results. The moss will expand as it absorbs water. Gently squeeze out excess water before use. When ready to use it should be lightly, evenly damp, not wet or dripping.

Best to only hydrate what you need, as you need it, as it will keep much longer stored dry not wet. How much water you add determines how long you need to soak it for. I find I tend to add too much water, and find 30 minutes soaking is plenty.

Spag moss has little to no nutrient value, so I create a yummy nutrient solution when I soak my spag moss. My usual go-to is seaweed and fertiliser. I use the Biopower organic seaweed flakes. About 2 grams per litre of water. Add some fertiliser. Give it a good stir, then soak my spag moss in that mixture. Since I most often use spag moss for propagation, my fertiliser go-to is GT CCS which is a specialist rooting fertiliser. For use in moss poles, I'll usually soak only in seaweed and add fertiliser when I water the plant.

When using spag moss by itself, pack it lightly in the pot, leaving lots of airy spaces between. This both increases oxygen for roots, but also means water is more evenly distributed. Most spag moss includes the occasional twig or leaf debris which you can pick out before use. Besgrow has very low debris compared to other brands I've used.

Why choose NZ sphagnum moss?

Home-grown and sustainably harvested from the Southern West Coast. Compared to lower quality spag moss that starts to breakdown and decompose in just months, NZ spag moss takes years to break down. The spag moss Besgrow uses is a long-strand spag moss which is nice and fluffy, making it more resistant to compacting, leaving roots plenty of air space for oxygen to help avoid root rot.

NZ spag moss is also known for lower salt accumulation to help avoid fertiliser burn. Since spag moss has little to no nutrient value, you will need to use fertiliser. If you get yourself fertiliser formulated for indoor plants you're on to a winning combo. For propagating I'm loving the GT CCS rooting fertiliser.

What is spag moss used for?

For propagation used by itself, and as an additive to your potting mix to increase water retention and aeration. Popular for cuttings and delicate baby plants, orchids, kokedama, hanging baskets, bare-root shipping to wrap roots and keep them moist during transport, and for retaining moisture for potted plants that dry out too fast. Very popular used to make moss poles also, especially used with the Grow Vertical mesh-front support poles.
