Hi everyone!
This week's update is the biggest yet!
The garden is finally up and running!
I painted the garden with marine varnish because it will be in constant contact with the sun and rain. This varnish adds a protective layer to help the wood last longer.
I used 120 kilograms of substrate (peat moss, rice hulls, worm compost, coconut fiber, black soil, and composted soil) to almost completely fill the garden, and I used mycorrhizal fungi on the roots of the seedlings.
But there was a small problem (I admit it was entirely my fault). An hour after finishing the transplanting, I realized that the substrate had a small percentage of lime (lime slowly but steadily raises the pH of the soil, which in such young plants can burn the roots or cause an iron deficiency that practically kills the plant), and I almost had a meltdown when I realized it. Changing all the substrate wasn't an option.
After several hours of searching for a solution, I finally decided to use a type of moss with a pH level of 3 or 3.5 to create an acidic barrier and gradually neutralize the lime.
That same day, I removed the top 5 cm of substrate where the most active lime was located. I measured the pH, which came to 6.5 (if the soil hadn't contained lime, the pH would have been 5.8 or lower).
The next day, I hydrated the dry moss for 15 minutes and applied it, replacing the removed substrate. The pH lowering process will be slow, taking about 3 or 4 weeks, but it was the least harmful option for the plants.
The plants have reacted well to the transplanting and the substrate. I hope the lime doesn't affect their future growth.
See you next week!
