6 Best Hot Climate Netting Patches For Fruit Trees That Stop Sun Scorch

You’ve seen it happen. One week your young apple tree is thriving, and the next, its leaves are crispy, and the fruit on the sun-facing side has ugly, bleached-out patches. That’s sun scorch, a common plague for fruit growers in hot, intense climates. It stresses the tree, ruins the fruit, and can leave permanent damage on the trunk and limbs. The solution isn’t more water; it’s providing a bit of well-placed shade with the right netting.

Understanding Shade Density for Sun Scorch Prevention

The first thing to get straight is that "shade cloth" is a bit of a misnomer. You aren’t trying to create total shade, which would halt photosynthesis and fruit development. You’re filtering the light, and the key metric here is the shade density percentage, which tells you how much light the fabric blocks.

For most fruit trees, including apples, pears, and stone fruits, a density of 30% to 50% is the sweet spot. This range cuts the intensity of the harshest midday and afternoon sun without starving the tree of the energy it needs to produce sugar and ripen fruit. Going over 50% can lead to reduced fruit color, lower yields, and weaker growth. It’s a balancing act.

Think about your specific situation. A young, newly planted tree with a vulnerable trunk might benefit from a 50% cloth for its first year to get established. However, a mature citrus grove that just needs relief during a brutal two-month heatwave might do perfectly with a 30% cloth. The goal is to reduce stress, not eliminate sunlight.

Agfabric Sunblock Shade Cloth for Versatile Use

When you’re starting out, Agfabric is one of the most common and accessible names you’ll find. It’s a solid, all-around choice that gets the job done without breaking the bank. This is the workhorse netting for a hobbyist with a mixed collection of trees.

Made from high-density polyethylene (HDPE), Agfabric is UV-stabilized to prevent it from disintegrating after one season in the sun. It typically comes with brass grommets along the edges, which makes securing it with zip ties or rope incredibly simple. You can find it in a huge variety of pre-cut sizes and shade densities, making it easy to find exactly what you need for a few dwarf trees or a longer row.

The tradeoff is that it’s not the most heavy-duty option on the market. In regions with exceptionally high winds or intense, year-round sun, you might only get a few seasons out of it before it starts to become brittle. But for its price and versatility, it’s an excellent starting point for protecting your trees from summer stress.

Coolaroo Shade Fabric for High UV Protection

Coolaroo is a brand many people associate with patio shades and pergolas, but their fabric is fantastic for horticultural use. Its primary advantage is its unique knitted construction. Unlike woven fabrics, this lock-stitch knit resists tearing and won’t unravel when you cut it. This is a huge practical benefit when you need to create custom sizes or cut holes for branches.

This fabric also boasts a very high UV block rating, often blocking up to 90% of harmful UV rays even at lower shade densities. This is crucial because it’s the UV intensity, not just the visible light, that does much of the damage. The material is also highly breathable, which is essential for maintaining good airflow around your trees and preventing heat buildup.

The main consideration here is cost. Coolaroo is a premium product, and you’ll pay more for it. However, if you live in a high-altitude area or a place like Arizona or Texas where the sun is relentless, the investment pays off in longevity. A Coolaroo panel will likely outlast cheaper alternatives by several years, saving you replacement costs and labor down the road.

VIVOSUN Sunblock Shade Cloth for Durability

If your primary concern is durability, especially against wind, VIVOSUN is a brand to look at. Known for their robust indoor growing equipment, their outdoor shade cloth is built with the same focus on toughness. The key feature is the heavily taped edges and reinforced grommet stitching.

Where other shade cloths might have a grommet rip out in a strong gust of wind, VIVOSUN’s construction is designed to hold fast. This makes it an ideal choice for exposed, windy sites or for larger, unsupported spans where the fabric will be under constant tension. A torn shade cloth halfway through a heatwave is a disaster, and this brand provides peace of mind.

This durability does mean the fabric can be a bit heavier and stiffer than other options. It’s less about delicate draping and more about creating a sturdy, semi-permanent shade structure. For anyone who has had to replace their netting mid-season after a summer thunderstorm, the extra reinforcement is well worth it.

FarmTek Knitted Shade Cloth for Orchard Rows

Once you move beyond protecting just one or two trees and start thinking about a whole row, buying small pre-cut patches becomes inefficient. This is where suppliers like FarmTek come in. They sell knitted shade cloth in large, continuous rolls, which is far more economical for covering multiple trees.

By running a high-tensile wire between two sturdy end posts, you can unroll and stretch this cloth over an entire row of trees, creating a protective tunnel. Because it’s a knitted fabric, you can cut it to the exact length you need without worrying about the whole thing fraying apart. This is the most practical way to scale up your sun protection efforts.

This approach requires more upfront planning and a bit of construction for the support structure. However, the result is a clean, effective, and long-lasting system. It’s the logical next step for the serious hobby farmer looking to protect a dozen or more trees efficiently.

Sunpro Plant Cover for Individual Tree Protection

Sometimes, you don’t need to cover an entire orchard. You just need to protect one specific, vulnerable tree—perhaps a prized Japanese maple or a newly grafted avocado sapling. For these targeted jobs, pre-made covers like those from Sunpro are an incredibly convenient solution.

These covers are often designed like a sleeve or a small, fitted tarp. You simply slip them over the young tree and secure them at the base. There’s no measuring, cutting, or building required. It’s a quick, five-minute job that provides instant protection.

The clear limitation is scale. This is not a cost-effective or practical solution for more than a few individual plants. But for giving a special tree the extra help it needs to survive its first brutal summer, the convenience can’t be beaten. It’s about applying the right tool for a very specific job.

Agtec Woven Shade Cloth for Extreme Heat Zones

For the most challenging environments—think the low desert or other areas with extreme heat and sun intensity—a standard knitted cloth might not be enough. Agtec’s woven shade cloth is the heavy-duty solution for these conditions. Woven fabric is generally denser and stronger than its knitted counterpart.

This material excels at blocking a tremendous amount of solar radiation, offering shade densities up to 95%. The tight weave provides superior heat blockage, which can lower the ambient temperature under the cloth significantly. This is the top-tier choice for protecting sensitive trees like avocados or citrus in climates where summer temperatures routinely soar past 105°F (40°C).

However, there’s a critical tradeoff: reduced airflow. The same tight weave that blocks heat can also trap it if not installed with plenty of ventilation. Woven fabric is also prone to unraveling when cut, so edges must be taped or sealed. It’s a specialized material that is incredibly effective when used correctly but can cause problems if installed poorly.

Proper Netting Installation to Maximize Airflow

Buying the right netting is only half the battle. How you install it is just as important as what you buy. The single biggest mistake is draping the shade cloth directly onto the tree’s foliage. This traps humid, stagnant air, blocks what little breeze there is, and can create a perfect environment for fungal diseases.

The correct method is to build a simple support structure around the tree or row. This doesn’t have to be complicated; a few T-posts or a basic frame made of PVC pipe or lumber will do. The goal is to suspend the netting at least 12-18 inches above and around the foliage. This air gap is non-negotiable. It allows heat to rise and escape while letting air circulate freely through the canopy.

Also, consider that you may not need to cover the entire tree. The most intense sun comes from the south and west during the afternoon. Often, a "lean-to" style cover that only protects those two sides is sufficient. This approach saves on material and maximizes airflow from the north and east, giving you the best of both worlds: protection where it’s needed and ventilation everywhere else.

Ultimately, choosing the right netting comes down to your specific climate, the number of trees you have, and your budget. Whether you opt for a versatile roll of Agfabric or a durable panel of Coolaroo, remember that proper installation with good airflow is the key to success. A little bit of shade, correctly applied, can be the difference between a lost harvest and a bounty of perfect, sun-kissed fruit.
