Protecting Strawberry Plants From Frost
Given the sensitivity of strawberry plants to freezing temperatures, it is essential to implement effective frost protection measures. This becomes particularly critical when temperatures drop below 28 degrees Fahrenheit (-2 degrees Celsius). There are various methods to shield strawberry plants from frost.
One popular method is the use of overhead irrigation. By applying water to the plants, heat is released as the water freezes, forming a protective barrier around the plants. It is crucial to begin the irrigation process if the air temperature falls below 34 degrees Fahrenheit and flower buds have already emerged. However, it is important to ensure proper water application and continue irrigation until the temperatures rise above freezing. Not providing enough water or stopping irrigation prematurely can actually cause more damage to the plants.
Another common approach to protecting strawberry plants from frost is the use of fabric or plastic row covers. These covers can be employed in conjunction with irrigation for enhanced frost protection. The effectiveness of the row covers depends on the type and weight of the fabric used. For instance, a row cover weighing 0.6 ounces per square yard can increase the temperature underneath by 2-3 degrees. Double-layer plastic covers can even raise the inside temperature by up to 10 degrees.

Cold Damage Risks For Potted Strawberries
When it comes to potted strawberries, extra attention and care are required, as they are more susceptible to cold damage compared to ground-planted strawberries. Potted plants lack the insulation provided by the surrounding soil, making them more vulnerable to extreme temperatures. Therefore, it is crucial to implement appropriate protective measures to ensure the survival and health of these plants during cold spells.
Digging holes and placing the pots in them with compacted soil and mulch can offer some level of protection for potted strawberries. The compacted soil and mulch act as insulators, shielding the pots from the cold air. Additionally, garages can serve as effective protection for potted strawberries, as the ambient heat against the walls provides insulation against freezing temperatures.
Using Mulch To Keep Strawberries Warm
Mulching is a tried and tested method for keeping ground-planted strawberries warm during the winter months. Proper mulching with organic materials can provide insulation, helping to maintain a stable temperature around the plants. However, it is important to choose a mulch with good drainage properties to avoid smothering the plants or creating an environment that encourages fungi and disease.
When selecting mulch for strawberries, it is critical to ensure that it will not retain excess moisture around the plants. Some suitable options include:
- Straw
- Pine needles
- Wood chips
These materials not only provide insulation but also prevent direct contact between the soil and the strawberries, reducing the risk of diseases. Applying a layer of mulch around the plants helps to:
- Regulate soil temperature
- Keep weed growth under control
- Protect the roots from freezing.

Cold Protection Methods For Strawberry Plants
To protect strawberry plants from the detrimental effects of cold temperatures, growers must be proactive and employ proper cold protection methods. Monitoring the forecast and temperature in the strawberry field is crucial for determining if protection is necessary.
In addition to overhead irrigation and row covers, there are other methods that can aid in protecting strawberry plants from frost and freeze events. Floatable fabric row covers can be used alongside irrigation to further protect the plants. The effectiveness of these covers depends on various factors, such as fabric weight and type. For optimal protection, it is recommended to apply the covers the afternoon before freezing temperatures are expected, allowing them to trap heat and provide insulation throughout the night.
It is important to note that day-neutral strawberries, during their planting year, do not usually require spring frost protection. This is because the flowers are typically removed until the danger of frost has passed. However, during subsequent years, frost protection measures should be implemented to ensure the health and productivity of the plants.
Understanding the temperature tolerance of strawberry plants is crucial for successfully growing and protecting them. Strawberry plants can withstand temperatures as low as 22 degrees Fahrenheit with frost protection, but their chances of survival decrease as the temperature drops. Implementing effective frost protection methods, such as overhead irrigation and row covers, can help safeguard the plants from cold damage.
