10 months have past, since I planted my blueberries from the nursery in 20 liter black bags.

I planted 5 plants of each variety in:
50% Compost
20% Perlite
20% Woodchips
10% Sphagnum moss

I planted 4 plants of each variety in:
30% Compost
30% Perlite
30% Woodchips
10% Sphagnum moss

Finally, I added one teaspoon of Aluminium Sulphate to keep the soil Ph between 4.5 and 5.5.

It is too early to draw any conclusions on the viability of a blueberry project in the Port Elizabeth region. It is impossible to see which varieties will do better in our climate, as none of the plants are bearing fruit.

So far, I have come across a concern. Blueberries are very thirty. 
I have to water my plants every second day or they show leaf loss.
This makes me wonder if a water needy project like this will ever be a good idea for a water scarce country.

Dixi seems to be most affected by the drought, with Misty being a close runner up. The other varieties are all very similar in water neediness.  

Happy New Year to all blueberry enthusiasts. May 2016 bring lots of growth and many berries.
