Yes, this really works: the seeds will germinate in the coffee filters, given the right conditions. This is an easy way to start plants indoors before spring planting. To start, add several seeds to a barrel-shaped coffee filter and spray it with water. Then fold the filter loosely and place it in a resealable plastic bag. Or, press the strainer into the bottom of a cup, add the seeds and pour in some water. The bag or cup can be left on the windowsill or in another place that has sufficient light and warmth.
Gardeners who use this method with paper towels find that the germinated seeds get stuck between the layers. This doesn’t happen with coffee filters, and the plant’s roots won’t get trapped either. Check the seeds for growth every few days and when the time comes, carefully remove the seedlings from the filters and plant them as usual.
