Pine needle soil is loose, breathable and fertile, and the soil is acidic, which is most suitable for planting plants that like acid and are afraid of waterlogging.For example, clivia, orchid, azalea, gardenia, jasmine, rubber tree, chlorophytum, amaryllis, camellia, coleus, Dieffenbachia, Anthurium, Hongyun dangtou, phlox, calceolaria, bellflower, inverted fuchsia, ball orchid, Strelitzia, impatiens, pansy, primrose, fuchsia crabapple and so on.
1. Collecting pine needles: Every year, there are a lot of pine needles piled up under the pine forest. We find a super-large plastic bag to sweep all the fallen pine needles home as the raw material for retting the pine needle soil.
2. Add soil to pile and retting: Find a plastic bucket with a lid, fill a layer of garden soil at the bottom of the bucket, lay a layer of pine needles, fill another layer of garden soil, lay a layer of pine needles until the bucket is full, ensure that the top layer is soil, water the soil to wet it, and put the lid on a place where the temperature is high.
3. Judging the maturity: The pine needle soil ferments the fastest under the condition of high temperature. It can be decomposed in three months in summer and almost half a year in winter. You can observe the pine needles in the soil. If they are almost rotten and become dark fine soil, it shows that they are well decomposed.
4. Insolation and disinfection: Before planting flowers, the retted pine needle soil should be exposed to the hot sun for three days, during which the soil should be often turned over to eliminate the insect eggs and pathogens, and then mixed with other substrates for use.
