Why Bio Leaf?

I really disliked repotting. Until now. This mix is a joy to work with. Less mess. Easier clean-up. Also seriously good for my plants. Lucky things. Talk about spoiled. I love it. My plants love it. Win win.

The same 'recipe' as the Bio Leaf Aroid and Hoya Medium / Chunky Mix, but a Fine / Medium blend with smaller grade ingredients. The ideal all-rounder for a 'mixed jungle' of indoor house plants. This is for the 5 litre size, enough to pot around 8 to 15 medium size plants depending on pot size, and whether filling pots completely, or retaining soil from the previous pot.

Which plants is it best for?

This is a superb, all-purpose, indoor houseplant mix. The best choice when you want 'one for everyone'. Especially suited to younger, less established plants. Plants in smaller pots with shallower root systems. And for plants you don't want to water constantly, as although still light and free-draining, this finer mix retains a little more moisture than medium or chunkier grades. This is also my go to for shifting water propagated cuttings to soil when ready to pot-up. My peace lily, syngonium, ZZ and many more are loving life in this blend.  

What's in the bag?

A fine, airy, free-draining mix of fine Orchid Bark, fine Pumice, Fern Fibre, Crushed Horticulture Charcoal and the Bio Leaf Bioactive Blend. NO slow-release fertiliser. You can safely use fertiliser, rooting hormones or growth boosters as normal.

Orchid bark

An obvious inclusion if you consider what epiphytes like to attach to and grow on. A premium, export-quality, fine grade orchid bark. Very clean and sterile. Minimal soil or dust. You can pre-soak, but it's not required at this level. Some barks break down fast. This harder, slow-to-decompose premium grade lasts years. Keeps soil aerated for oxygen to reach roots, resists compacting and provides drainage while also holding on to water for roots to take up as needed. 

Pumice

A natural, volcanic rock that keeps its shape even when soaked in water, keeping soil loose. Adds aeration and improves drainage. Keeps water moving to prevent substrate and plants becoming waterlogged. Naturally porous. Pumice holds water roughly twice as long as bark, releasing it slowly and steadily for the roots.

Fern fibre

Superb growing medium for many indoor plants. Great results reported for aroids, hoya, orchids, ferns and other epiphytes. A natural, soft, airy, fibrous, long lasting material containing a lot of air. Can retain a lot of water. As it holds water for longer than many free-draining substrates, you won't have to water as often. Ideal for indoor plants that prefer moist to lightly moist conditions, who don't like to fully dry out. Fibrous nature distributes more even moisture throughout the pot due to natural capillary action.

Horticultural charcoal

Horticultural charcoal for plants is different from activated charcoal that you might be familiar with for human health. This is the over-waterers and worried-plant-parent's best friend. Horticultural charcoal helps increase aeration and adds drainage to soil mixes for potted plants. Its natural porosity helps charcoal hold on to necessary nutrients for roots to access. Horticultural charcoal also helps create a more favourable environment for good bacteria and beneficial microbes for healthier soil, and helps balance soil pH.
