Product Details

These thick plastic Seedling Heat Mats have an embedded heating wire inside. Because the thermostat is outside the mat, the heat given off by the mat is related to the temperature of the surrounding air. So, when the room is cool, the mat is 5-11°C (10-20°F) warmer than that. And when the room or cold frame is warm, the mat is much warmer. In late spring when the surrounding temperature (not soil temperature) is over 24°C (75°F), it is best to unplug the mat so that the seedlings do not become too hot. Direct sunlight will overheat the air surrounding your flats and cause overheating as well.

How To Grow Seedling Heat Mats

Growing

This blend of Micro-clover and Tall Fescue seeds takes a two-pronged approach at defeating the chafer beetle. This blend is meant for use with new, bare topsoil, and not for over-seeding existing lawns. Keep the newly seeded area well-watered as the seedlings take root. Onceestablished, this lawn will require regular maintenance, but it will stay greener for longer in the summer, and it will stand up to foot (and pet) traffic in areas of full sun to partial shade. Clover may go dormant over winter, and may appear to die back, so the fescue in this blend will keep lawns looking healthy and vibrant. This blendcontains95% Tall Fescue and 5% Micro-clover.

Starting

Spread the seed on bare soil, with no turf present, at a rate of 3.6kg (8 lb) per 1000 square feet. Seeding over existing thatch is rarely successful. Because lawn spaces tend to be large, we recommend erring on the side of caution.It’sa good ideato withhold 15-20% of seeds for filling in any bald areas later. All new plantings should be kept damp until the plants areestablished.

Timing

Sow in the period two weeks before, to eight weeks after, the last frost date. Or, in areas with mild winters, sow in early autumn, approximately eight weeks before the first frost date.
