This is a mix i have used for years which works very well with olives grown outdoors or under glass. 

Contains a proven mixture of sustainably sourced orchid bark in fine to medium grade (5-10mm), horticultural sand and peat free potting medium 

The bark is from FSC mixed sources at a minimum of 50% and is Soil Association approved
Naturally durable and stable with a long lasting structural strength
Provides high and resilient air-filled porosity
Prevents water logging in the lower layers of the pot
Promotes vigorous healthy root growth

The sand is organic and sustainably sourced and of horticultural grade and the potting medium is fully organic and peat free.

All my potting mixes are made to order, Organic and sterilised. They are always fresh the day they are shipped.

Comes in simple bags ready to use. ideal for home use. Each order receives a 1 litre volume. Enough to fill a 1litre (13cm diameter) pot when empty. I mix these to order so can complete others volumes upon request and do offer discounts on higher volumes.

I do my best to keep postage charges as low as possible, asking enough to cover the stamp and box only.

I always combine shipping on multiple orders. And offer discounts off the items themselves so the more you buy the more you save. 

If discounts arent automatically combined when making payment please contact me for a refund of the excess charge.
