Growing methods and precautions for the Dracaena deremensis 'Janet Craig'

I. Growing methods

1. Prepare the substrate for planting the Dracaena deremensis 'Janet Craig'. You can use loose, well-drained, well-aerated imported Pindstrup peat in the 5-40mm specification. Add water to the peat and mix well, then wait to plant it in cups. For a 14cm pot, the peat used per pot is about 400 milliliters, and one 300-liter bag of imported peat can fill about 750 cups.

2. Choose high-quality seedlings from professional production, with a seedling height of 11cm, a crown width of 7-8cm, and no pests or diseases, no dead leaves, yellow leaves, etc. When potting, generally use a pot with a caliber of 14cm. When planting, first place about 2cm of substrate at the bottom of the cup, then move the screened seedlings into the cup. Small seedlings should not be planted too deep; it is best to keep them level with the base of the plant. The substrate should be moderately firm, filled to 9/10 of the cup.

Add water to the peat and mix well (standard for adding water: after adding water and mixing well, squeeze a handful of peat tightly in your hand and water seeps out between your fingers). Wait to plant it in cups. For a 14cm pot, the peat used per pot is about 400 milliliters, and one 300-liter bag of imported peat can fill about 750 cups.

3. Requirements for potting seedlings: choose high-quality seedlings from professional production, with a seedling height of 11cm, a crown width of 7-8cm, and no pests or diseases, no dead leaves, yellow leaves

4. Potting: for old pots that are reused, they must be soaked in a 1000-fold potassium permanganate solution for more than half an hour, then rinsed with clean water, and dried for later use. Generally use a pot with a caliber of 14cm. When planting, first place about 2cm of substrate at the bottom of the cup, then move the screened seedlings into the cup. Small seedlings should not be planted too deep; it is best to keep them level with the base of the plant. The substrate should be moderately firm, filled to 9/10 of the cup.
