In northern areas - where the growing season is short - season extenders make a huge difference. They allow you to grow crops that require long seasons and give shorter season crops a head start with the result that your crop yields increase by up to 40%. Place row covers over garden beds and secure them with garden staples or biodegradeable pegs. Put down red film and trays to stimulate plant growth. Both strategies are invaluable to success in the garden.
Floating row covers trap heat and moisture. Spread them on your seed beds for quicker germination at the start of the season. After seeds have sprouted and the plants have grown, you can float row covers without support directly on your plants to protect against late frost, insects, critters and birds. You can also drape them over hoops and anchor them to create a mini greenhouse.
In addition to helping warm up the soil and keep moisture in, red products reflect light back onto plants to stimulate growth and increase productivity. An extra bonus is protections against cutworms. Use the red film mulch under tomatoes, strawberries, melons and other ground fruiting plants. Use anchors to keep the film in place.
