Use Propagation Mats to Start Your Seeds

Many gardeners rely on propagation mats (also referred to as heat mats) to provide an essential source of heat for seed germination. They report faster germination time, fewer unsprouted seeds, and healthier seedlings. The heat that radiates into the root area also helps to produce a stronger root structure for a hardier plant. In cooler climates, seedlings need to be started early, and spend a greater amount of time growing in the protection of your home or greenhouse. Propagation mats can make the germination process go more smoothly and yield hardier seedlings that are more likely to survive until transplanting time and beyond. Here are some simple steps to follow:

• Plant your seeds at the appropriate depth for the seed type, this depth can be found on the back of the seed packet. Make sure that the planting medium is moist, and then cover the seeds with 1/8’’ perlite, or any light and loose material to make it easy for sprouting seedlings to emerge.

• Water planted seeds gently to avoid disturbing the cover medium and dislodge the seeds.

• Loosely lay plastic over the top of the tray, or use the clear plastic covers that come with some trays.

• Place the tray on the propagation mat and then set the thermostat to the required temperature.

• It is a good idea to use a thermometer placed on top of your planted seeds to make sure that temperature remains at the desired level.

• Be sure to check moisture daily and water as needed – heat can dry out the root area and it is especially important for your sprouting seeds to stay warm.

• When seedlings emerge, move the trays to a spot where they will receive appropriate light. Place as close to the light source as possible—many seedlings become ‘leggy’ when forced to reach for a distant light source.

• Remove from the heated propagation mat, unless you are growing warm weather crops such as tomatoes or peppers— many varieties benefit from the root warmth.

As for the propagation mats, you’ll find a wide variety of sizes and thicknesses from which to choose. It is advisable to use a thermostat so that you can control the temperature relative to the type of seedlings you are starting. You can find desired germination temperatures listed on seed packets or in some seed catalogs.
