If you’ve ever watched helplessly as a sudden storm destroyed your garden, you’re not alone. Denver’s weather can shift in minutes—one moment it’s sunny, and the next, you’re dodging hailstones. This unpredictable climate makes it especially hard for gardeners and homeowners who take pride in their outdoor spaces. Hail damage in Colorado is no joke. In fact, according to the Insurance Information Institute, Colorado ranks second in the U.S. for hail claims, with Denver being one of the hardest-hit areas each spring and summer.

Hailstorms in Denver tend to strike between May and July, catching many gardeners off guard. As someone who lost a season’s worth of tomatoes and dahlias in a brutal storm in 2021, I understand the pain. After that storm, I made it my mission to learn and apply everything I could to protect my garden. That journey, filled with trial and error, led to the tips you’ll read here—tested, reliable, and homeowner-approved.

Understand the Risks: Why Denver’s Hail Storms Are So Severe

Denver known for its beautiful landscapes and outdoor lifestyle is also notorious for violent weather swings. One minute it’s sunny, and the next, your roof and garden are taking a beating. According to a 2023 report by NOAA’s Storm Events Database, Denver experiences between 10 to 15 hail days per year on average. These aren’t just harmless little pellets either—hailstones can grow to golf-ball or even baseball size during severe storms.

Denver’s location along the Front Range exposes it to converging air masses from the mountains and plains, which often fuel intense thunderstorms. These storms can develop fast, making it difficult to prepare unless you have a system in place.

In 2017, a single hailstorm in Denver caused over $2.3 billion in damages, according to the Rocky Mountain Insurance Information Association. The bulk of this damage impacted vehicles, rooftops, and—you guessed it—home gardens.

Understanding these risks is the first step in shielding your plants. It’s not just about reacting after the storm but creating a garden strategy that’s built to last.

Use Hail Netting and Plant Covers: Your First Line of Defense

One of the simplest and most effective ways to protect your plants is with hail netting. This material acts like a shield, deflecting hail without suffocating your plants. I personally use high-density polyethylene netting, which allows light and water to pass through while stopping hail in its tracks.

Here’s how to apply hail netting correctly:

1. Frame it: Use PVC or metal piping to build a structure over your garden beds.
2. Secure it: Attach the netting with clips or zip ties to prevent it from blowing away.
3. Anchor it: Stake the corners into the ground to withstand strong winds.

You can also use floating row covers for smaller plants or seedlings. These are lightweight fabrics that protect without overheating your garden. If you’re planting sensitive veggies like lettuce or herbs, floating covers are a smart choice.

Additionally, collapsible mesh cages can be a practical solution for patio or container gardens. These fold away for easy storage when not in use.

Build or Buy a Hail-Proof Garden Structure

If you’re looking for something more permanent, consider investing in a hail-resistant garden structure. This could be a mini greenhouse, a shade pergola, or a custom hail house.

Mini greenhouses made with polycarbonate panels are especially popular in Denver. Unlike glass, polycarbonate is flexible and can absorb the shock of hail without breaking. Some even come with ventilation options to avoid overheating your plants during hot days.

I built my own 6×10 greenhouse using twin-wall polycarbonate panels and a simple aluminum frame. It not only protected my tomatoes from hail but extended my growing season by nearly two months.

Here are a few ideas:

• DIY Options: Build a lean-to greenhouse against your home’s south-facing wall.
• Prefab Structures: Consider hail-tested greenhouses from trusted brands like Palram or Rion.
• Custom Add-ons: Install retractable awnings or shade cloths that you can roll out when hail is in the forecast.

These investments can cost a few hundred dollars, but they pay for themselves by preserving hundreds in plants and produce.

Time Your Planting Around Hail Season

Timing is everything in gardening—especially in Denver. Since most severe hailstorms happen between mid-May and late July, planning your planting schedule accordingly can reduce risk.

For example:

• Start cool-season crops early: Spinach, peas, and radishes can be planted in late March or early April.
• Delay sensitive warm-season crops: Wait until late June to transplant tomatoes, peppers, and cucumbers.

You might lose a few weeks of growth, but you’ll protect your investment from the most dangerous storm period. If you use indoor seed starting or a greenhouse, you can keep your young plants safe until the worst part of the season has passed.

According to the Colorado State University Extension Office, adjusting your planting window by just two weeks can reduce your hail exposure by up to 40%.

So don’t rush it—plan smart, plant later, and your garden will thank you.

Create Windbreaks and Natural Hail Barriers

Hail often rides in on fast-moving storms, and wind is a big part of the damage. Creating windbreaks can reduce hail’s force and give your plants a better chance of survival.

Here are a few natural windbreak options:

• Plant tall, sturdy shrubs: Lilac, juniper, and viburnum can block wind while adding beauty.
• Install garden trellises: Use wood or metal to build vertical screens that double as support for climbing plants.
• Use fencing smartly: A solid wood fence or lattice fence covered in vines helps disperse wind energy.

I once used five large sunflowers planted in a row as a makeshift barrier. Not only did they block a lot of wind, but they also took the brunt of the hail, saving the smaller plants behind them.

In urban gardens, even a few strategically placed large pots or garden sculptures can redirect wind and reduce hail impact.

Monitor Weather Alerts and Act Fast

Sometimes the best defense is simply being alert and ready. Download a real-time weather alert app like MyRadar or the NOAA Weather Radar Live. These apps can warn you 10–20 minutes before a hailstorm arrives, giving you time to cover plants or move potted ones to safety.

Keep a “hail emergency kit” near your garden supplies. Include items like:

• Pre-cut hail netting
• Plant covers or buckets
• Stakes and clips
• A weather radio (for power outages)

I keep my kit in a waterproof bin near my back door. It’s saved my garden more than once.

And don’t underestimate the power of a neighbor text chain. We have one on my block, and whenever hail is on the radar, someone sends out an alert—often faster than the apps.

On average, Denver sees 10 to 15 hailstorms per year, with most occurring from May through July.

Are greenhouses totally hail-proof?

Not entirely, but polycarbonate greenhouses are highly resistant and can withstand most small to medium hailstones.
