Understand if Spreadsheets Effectively Shield Plants from Frost?
When the first warmth of spring tickles gardener's noses, they dart towards the nursery. Loaded with pots and dreams, they plant their vibrant flowers and precious vegetables. However, the sudden appearance of a chilly forecast sends those frost-susceptible plants scurrying for shelter. Unprepared, gardeners rummage around the house in search of anything to safeguard their plants against the sobering chill. Many find themselves draping their old bedsheets over their beloved plants, but does this homemade shield truly protect against the icy freeze? Believe it or not, many seasoned gardeners advocate for using bedsheets during brief cold spells, and here's why.
The Chilly Logic Behind Covering Plants
Annual flowers, tender vegetables, and frost-fragile tropical plants reveal visible damage upon their foliage freezing. Tissue degradation results in wilted or charred leaves and stems. Plants that have braved the winter in the garden might fare well in a freeze, but once they flaunt radiating new growth, they become susceptible to frost damage. Covering these fragile plants during the dark, chilly nights enables them to retain a bit of ground-radiated warmth, thus preventing the bitter chill from seeping directly through their tender leaves.
The Warmth of Bedsheets
In a pinch, sheets can provide a degree of insulation, especially those made from breathable fabric. Excessive moisture or overheating can do more harm than good, which is why sheets perform well in comparison to non-breathable and non-insulating materials like plastic. Thicker sheets offer more protection than their thinner counterparts, while pairing two sheets can provide added security.
Fabric covers, however, have their limitations. Once the temperature plunges below 28 degrees Fahrenheit, their ability to ward off frost wanes. Cold frames, hoop tunnels, and greenhouses are better suited for extreme cold during the winter months.
Your Garden's Cozy Tent
To successfully cover your garden with sheets, embrace these tips:
- Install the cover in the evening, while there's still remnants of sunlight. The extended daylight allows for better heat retention.
- Select a sheet that's large enough to drape completely over the plants and extend down to the ground, ensuring optimal insulation. Stones, bricks, or stakes can anchor the sheet in place.
- Attempt to keep the material from directly coming into contact with the fragile foliage. Stakes, hoops, tomato cages, or any other available implements can help create a tent-like structure.
- Remove the covers before midday, to prevent overheating.
The Dilemma of Bedsheets vs. Frost Cloth
If your garden consistently finds itself in the throes of winter, investing in frost cloth may be the better choice. Lightweight and breathable, the polypropylene fabric of frost cloths allows for excellent heat retention and light penetration, while also drying swiftly.
Determining the optimal weight of cloth depends on your locale's anticipated chill, with heavier cloths offering added protection. If temperatures dip below freezing during the day, frost cloths eliminate the need for constant removal and replacement.
