Best Potting Soil for Propagation?
I need some help in purchasing potting soil for propagation of hydrangea cuttings. I have had some successes and more failures than normal with what I think is a soil deficiency from bags of soil purchased this year from the big box stores. I have had numerous yellow leaves, dieing plants, and unhealthy looking propagates. Other leaves look brownish and crispy and I have watered the pots faithfully.
Someone said it was a lack of iron, so I checked the bag and no iron was mentioned. I purchased some granular iron and worked it in the pot - but the plants died anyway. One suggested the soil of Miracle Grow. PLEASE what do you folks use? Our natural soil here is heavy in clay so it will not work. Any advice will be so greatly appreciated.
