I have recently repotted a group of areca plants. Since i killed a group areca plant last year for having repotted in with just a peat moss (leaves turned dry in just one night).
So for the first time this year, i tried to experiment what went wrong and t learn from mistakes.
4 days ago, i started to experiment repotting a new group of arecas with a mix of:
3 part peat moss
1 part river sand
0,5 part of potting mix (w/ compost material)
0,5 part of wormcasting
but the day after, same thing is happening with 3 out of 10.
For avoiding to lose all of them. Today i tried a new composition and risked to repot them again for the second time.
3,5 part peat moss
2 part river sand (1mm - 3mm)
0,6 part Worm casting
1 part potting soil
so im here to ask for a tip from people who has more experience.
I expected to see a good drainage adding river sand, but it actually took minutes to flush the excess water. Why leaves turn dry? I added sand to increase aeration. Do you think, i should've used coco coir?
Why these things occur? Is low draining mix bad? What is the ideal mix?
