Few things can break a gardener’s heart as much as damping off. Caused by a fungus, damping off will destroy a seed’s tissue, sometimes before it has a chance to germinate. Wet, cool soil is usually the culprit. Soilless mixtures, such as peat moss, perlite and rockwool cubes, can help gardeners avoid fungal problems. Rockwool is made from molten rock and pressed into pallets that can then be planted with seeds. When the seeds germinate, and roots begin to grow from the bottom of the cube, it’s time to plant the seedlings into the soil.
Fill the planting pots, to within 1/4 inch of the rim, with potting soil or the soil recommended for your seedlings.
Cut the rockwool cubes apart with scissors. Be careful not to cut into the seedlings' roots.
Dig a hole in the soil that is the same depth as the rockwool cube and twice the diameter, using your hand.
Remove any rockwool from the outside of the cube that you can gently tug away.
Place the cube into the prepared planting hole and pack the soil around the base of the seedling.
Water the seedling until the water runs out of the bottom of the pot and allow the pot to drain completely before placing it in its permanent location.
