Texas Snow - Protect Your Plants

We had snow twice in 2021 and I wasn't sure my garden would survive. I had newly tip layered blackberry plants in small pots now covered in snow. I also had new apple trees and a strawberry patch to protect. I used clear plastic containers to make some mini green houses to protect my celery and onion plants and this worked well. Check out the video above to see how it all worked out including the before and after.  

How to Protect Your Plants from Snow: Tips for Winter Plant Care

Winter can be a harsh season for your garden, especially when heavy snow, freezing temperatures, and harsh winds hit. While many plants are hardy enough to withstand winter, snow can present unique challenges, such as crushing delicate stems, damaging roots, or causing desiccation. If you want to keep your plants healthy and protected throughout the cold months, it's important to take the right steps to shield them from snow and frost. In this blog post, we’ll explore effective ways to protect your plants from snow and help them thrive during winter.

Why Snow Can Be Harmful to Plants

Before we dive into the protection methods, let’s take a quick look at how snow affects plants:

• Weight Damage: Snow can accumulate on branches and stems, causing them to bend, break, or snap. This is especially damaging to shrubs, trees, and delicate plants that aren't sturdy enough to support the weight.
• Root Damage: Prolonged freezing temperatures, combined with snow cover, can cause the ground to freeze deeply, potentially harming shallow roots. A sudden thaw, followed by refreezing, can cause "frost heaving," which dislodges roots and damages plant structure.
• Desiccation: Dry winter winds, often exacerbated by snow, can lead to dehydration in plants. This is especially common in evergreen plants that continue to lose moisture through transpiration even in winter months.
• Damping-off Disease: Snow can melt and create wet conditions that promote fungal diseases, particularly in seedlings or vulnerable plants.

Tips for Protecting Your Plants from Snow

Fortunately, there are several steps you can take to minimize snow-related damage to your plants. Here are some essential tips:

1. Mulch Your Plants

One of the best ways to protect plant roots and retain moisture during the winter months is by adding a layer of mulch around the base of your plants. Mulch acts as an insulating blanket that helps regulate soil temperature, keeping the roots warmer and more stable.

• How to Apply Mulch: Apply 2-4 inches of mulch, such as straw, wood chips, shredded leaves, or compost, around the base of the plant. Be sure to keep the mulch away from the plant stems or trunks to prevent rot.
• Benefits: Mulching helps prevent frost heaving, maintains soil moisture, and protects the roots from extreme cold.

2. Wrap Vulnerable Plants

For young trees, shrubs, or delicate perennials, protective wrapping can shield them from the snow’s weight and cold temperatures. Use materials like burlap or frost cloth to create a barrier between the plant and the elements.

• How to Wrap Plants: Gently wrap the plant or tree in burlap or garden fabric, securing it loosely with twine or string. Make sure there’s some space between the fabric and the plant to allow air circulation and prevent moisture buildup, which can lead to mold.
• Additional Tip: If you're wrapping smaller shrubs, you can build a cage around the plant using chicken wire and then cover it with burlap for extra protection.

3. Support Branches with Stakes or Guards

For plants with heavy branches or vines that might be susceptible to breaking under the weight of snow, consider adding supports to help them stand strong.

• How to Support Plants: Use bamboo stakes, wooden stakes, or plant supports to prop up branches. Alternatively, wrap trees and shrubs with snow guards—specialty netting or mesh designed to distribute snow evenly and prevent heavy accumulations on branches.
• Why It Works: Properly supporting branches prevents them from bending, snapping, or even breaking off under the weight of snow.

4. Cover Plants During Heavy Snowfall

When heavy snow is forecast, covering your plants can protect them from direct damage. Use frost cloths, tarps, or old sheets to cover plants temporarily. This is especially helpful for smaller shrubs, flowers, or tender vegetables.

• How to Cover Plants: Drape a light cloth or plastic tarp over plants before the snow starts falling. Be sure to avoid using plastic directly on plants, as it can cause condensation and lead to frost damage. Instead, create a frame with PVC pipes or stakes to hold the cover off the plant.
• Important Tip: Once the snow has passed, remove the covers so the plants can get sunlight and airflow.

5. Prune in Late Fall

While pruning should be done carefully, removing dead or damaged stems and branches before snow falls can help prevent additional stress on your plants.

• How to Prune: Remove any broken, dead, or diseased branches that might be more vulnerable to the snow’s weight. Be cautious not to prune too much, as plants need their remaining growth to stay insulated during the winter.
• Why It Helps: Pruning removes weak or damaged branches that might bend under the weight of snow, reducing the chance of breakage.

6. Consider Snow Fencing or Snow Guards

If you live in an area with frequent heavy snowfalls and wind, using snow fencing or snow guards can help reduce the amount of snow accumulation on your plants. Snow fencing is designed to divert snowdrifts and reduce wind exposure to sensitive areas of your garden.

• How to Install: Place snow fences along the perimeter of your garden or around vulnerable plants. The fencing will block the wind, reducing snow accumulation around your plants and minimizing the chance of damage.

7. Water Your Plants Before Winter Hits

While you may think winter means no more watering, it's still important to hydrate your plants before the freezing temperatures arrive. Well-watered plants are better equipped to handle the cold.

• How to Water: Water plants thoroughly in the late fall, making sure the soil is moist but not waterlogged. This gives the plants enough moisture to get through the dry winter months without becoming dehydrated.

8. Protect Potted Plants

For plants in containers, snow can pose a particular challenge, as the soil in pots freezes more easily than in the ground. To protect potted plants, move them to a sheltered location like a porch, garage, or shed. Alternatively, wrap the pots in insulating materials like burlap or bubble wrap to prevent freezing.

• How to Insulate Pots: If moving the plants indoors isn’t an option, wrap the pots with burlap, foam, or old blankets. You can also place the pots in larger containers filled with insulating materials like straw or leaves.

Additional Tips for Snowy Winters

• Plant Cold-Hardy Varieties: When planning your garden, choose plants that are naturally suited to cold climates and can tolerate heavy snowfalls.
• Snow Removal: Gently brush off snow from branches with a broom to avoid breaking them. Be sure to do this before the snow turns to ice, as it will be harder to remove.
• Avoid Salt: If you live in an area where roads and walkways are salted, be cautious about salt runoff getting on your plants. Salt can dry out and damage plant tissues. Consider using alternative deicers like sand or kitty litter near your garden.

Conclusion

Snow doesn’t have to mean the end of your garden for the season. By taking simple but effective steps, you can protect your plants from the damaging effects of snow, frost, and freezing temperatures. Whether you’re mulching, wrapping, or providing extra support, these winter care techniques will help ensure your plants stay safe and healthy through the harsh winter months. When spring arrives, your garden will thank you for the care and protection it received during the snow-covered season.
