Weekly DIY: Cold Frame

<p><img src="/files/images/coldframe-b.png" border="0" width="230" height="217" />This weekend we got the first tantalizing taste of spring as the weather was clear and bright and temperatures rose well above freezing for the first time in months. Snow melted (though not entirely yet), and started the <a href="/blog/2007/03/13/lets_talk_about_it_sustainable_gardening_tips">thoughts of summer gardens</a> in mind. But nighttime temperatures are still falling below freezing, and it's far too early to put plants in the ground, unless you provide a little assistance.<br /><br />If your garden has a spot with good access to the sun throughout the day, you can use a cold frame to start your plants earlier in the year than you would otherwise. A cold frame is a very simple item. It is really just a small greenhouse. Daytime sun will warm the air and the ground inside, making it easier for plants to start growing. Nighttime temperatures inside the cold frame may fall back close to outdoor ambient temperature, but the extra heat gained during the day and the wind protection the encosure provides will help keep the plants alive even if there is an overnight frost.<br /></p>
