Getting Your Garden Ready for Cold Weather

Cold snaps in North Florida and South Georgia can catch even seasoned gardeners off guard. While we may not deal with long stretches of freezing temperatures, sudden drops into the 20s and 30s can cause real damage to plants, trees, lawns, and even your home’s plumbing. A little preparation goes a long way in protecting your landscape investment.

Understanding Bark Splitting on Azaleas and Trees

One of the most alarming sights after a hard freeze is bark splitting, especially on azaleas. This usually happens when cold temperatures follow a warm spell. The outer bark cools and contracts faster than the inner wood, causing vertical cracks along the trunk or branches.

What to do if you notice a split:

• Don’t panic, many bark splits look worse than they are.
• Leave the damaged area alone and allow it to dry naturally.
• Do not seal the split with paint or tar.
• Keep the plant well-watered (but not soggy) so it can heal.

The good news is that most trees and shrubs will heal themselves over time. As long as the split doesn’t completely girdle the trunk, the plant can recover with proper care and patience.

Cold-Weather Protection Products We Carry

At Esposito’s, we stock practical, proven products to help protect your plants and home during freezes.

Frost Cloth (Freeze Fabric)

Frost cloth is one of the most effective tools for protecting plants from cold damage.

How to use it correctly:

• Cover plants all the way to the ground to trap warmth rising from the soil.
• Secure the cloth with stakes, bricks, or landscape pins so cold air can’t blow underneath.
• Remove the cloth once temperatures rise to prevent overheating.

C9 Lights

Traditional C9 incandescent lights give off gentle, consistent warmth and are highly recommended for protecting palm trees during cold weather.

• Wrap the lights around the trunk, starting at the base and working upward toward the crown.
• On smaller palms, lights can also be lightly woven into the fronds.
• Always use outdoor-rated lights and extension cords.

C9 lights are also effective for tender shrubs, citrus, and young trees, but they are one of the best tools for keeping palms warm during freezes.

Using C9 Lights on Citrus Trees

C9 lights are an excellent option for protecting citrus trees, especially young or recently planted trees that are more vulnerable to cold damage.

• Wrap lights around the trunk and main scaffold branches, starting near the soil line.
• Focus on protecting the trunk, as trunk damage can permanently affect citrus health.
• Use incandescent C9 bulbs only, LED lights do not produce heat.
• Avoid tightly wrapping bulbs against leaves or fruit; the goal is gentle ambient warmth.
• Combine lights with frost cloth over the canopy for added protection during hard freezes.

When used properly, C9 lights can help citrus trees safely ride out freezing nights and rebound quickly once temperatures warm.

Faucet Covers

Freezing temperatures can burst outdoor pipes.

• Faucet covers are an inexpensive way to prevent costly plumbing repairs.
• Install them before temperatures drop below freezing and remove once the danger passes.

Why You Shouldn’t Use Plastic on Plants

It may seem logical, but plastic sheeting can actually cause more harm than good.

• Plastic traps moisture, which can freeze and damage plant tissue.
• When plastic touches leaves, it can cause burn spots during freezing conditions.
• Plastic prevents proper air circulation.

If you must use plastic in an emergency, always place a barrier (like stakes or hoops) so it never touches the plant, and remove it as soon as temperatures rise. Frost cloth is always the better option.

What Not to Do After a Freeze

It’s tempting to act quickly after cold damage, but some common responses can make things worse.

• Don’t prune damaged plants right away.
  Pruning too soon can expose plants to further cold damage. Wait until spring when new growth shows you what’s truly alive.
• Don’t apply fertilizer or weed control products.

Fertilizing during cold stress can push weak, tender growth at the wrong time. Weed control products can also stress already damaged lawns and plants.

Helping Your Lawn Survive Winter: The Role of 5-0-20

Applying a 5-0-20 winterizer fertilizer in the fall can make a big difference in how your lawn handles cold weather.

• The high potassium strengthens roots and improves cold tolerance.
• It helps turf recover faster from winter stress.
• Stronger roots mean a healthier, greener lawn come spring.

Fall is the time to build resilience, winter is when your lawn uses it.
