This quality grade orchid bark(approx 12-20mm fractions) can be used alone or as a base to make your own special orchid compost blend from products from our potting media range. Orchid Supplies UK will freshly hand prepare your own compost upon request to any quantity!
New & now graded to 12-20mm, used to be 15-28mm which was coarse.
Used alone will provide a very chunky airy mix that will require lots of watering.
Adding other products like sphagnum moss, small bark, GS2 Mix This-like sponge rock, P35 coarse perlite,clay pebbles will give you options to create you own mix to suit your conditions.
Cattleya Tip - like an open mix but medium grade bark may not be quite right on its own for some, concider adding some sphagnum moss and GS2 Mix This to suit.
Tip for Paphiopedlium - (1)A common ratio is four parts bark (small or medium depending on root size/Paph) (2)one part perlite(we recommend GS2 Mix This) (3)one part charcoal 10mm -optional.
Please Note - This medium bark is slightly different in size to our previous medium grade bark now approx 12-20mm fractions, it is still of the same high quality.
