Garden Parasol Cover: How to Choose, Fit and Protect Your Shade
The quick answer: A good garden parasol cover is water-repellent, UV-resistant and measured to fit your canopy with a little room to spare. Cantilever parasols need a cover with a zip or side opening and a secure drawstring hem. Fit it dry, fasten it snugly, and it can add years to your parasol's life.
Why a Garden Parasol Cover Is Worth Every Penny
A parasol works hard in a British garden. It's opened in bright sun, soaked by a surprise shower, then left standing while the weather changes again. A cover is the cheapest way to stop that wear from adding up.
It Keeps Rain and Mould Away
Damp canopy fabric that's left folded or unprotected is the perfect home for mildew. Once those dark spots appear, they're hard to shift. A waterproof cover keeps the canopy dry between uses, so it stays fresh.
It Stops UV Fading
Even on cloudy days, UV rays slowly bleach fabric. Deep reds and blues fade first, leaving your parasol looking tired after a couple of summers. The NHS explains why sun exposure matters for people, and it's just as hard on outdoor fabric. A cover takes the hit for you.
It Protects Against Wind, Dust and Bird Droppings
Covers also keep off pollen, dust and the occasional unwelcome gift from above. When you open the parasol, it's clean and ready.
The Hidden Cost of Skipping One
Replacing a large parasol is far more expensive than buying a cover. It's the classic small purchase that saves a big one.
How to Choose the Right Garden Parasol Cover
Step One: Measure Your Parasol Properly
Don't guess. A cover that's too tight tears at the seams, and one that's too loose flaps in the wind.
Height
Measure from the base of the canopy to the very top of the pole or finial, with the parasol closed.
Canopy Diameter
Measure the widest point of the folded canopy, not just the open span.
Pole or Rod Position
This matters most for a cantilever parasol, where the offset pole changes how a cover needs to open and close.
Step Two: Match the Cover to Your Parasol Type
Centre-Pole Parasols
These are the classic garden shape, often set through a table. Most standard covers fit them well.
Cantilever Parasols
The offset arm means you need a cover with a side zip or wide opening. This weatherproof cantilever parasol cover is designed for exactly that job.
Large Rectangular or Banana Parasols
These need longer covers with reinforced seams. Always check the length against your measurements, not the photo.
Fabric and Features: What to Look For
Material
Look for a tough polyester or Oxford-style fabric with a waterproof coating. It should feel firm and not thin. Thin fabric can crack or leak at the seams.
Ventilation
Small vents let trapped moisture escape. Without them, condensation can build up inside and cause the mould you were trying to avoid.
Fastenings
-
A drawstring hem keeps the cover from lifting in gusts.
-
A zip or Velcro opening makes fitting easier, especially on tall parasols.
-
Straps or toggles give extra security on exposed patios.
How to Fit Your Parasol Cover (Without the Wrestling)
-
Let the canopy dry. Covering a damp parasol is the fastest way to grow mildew.
-
Close it fully and fasten the tie or strap.
-
Slide the cover over from the top down, keeping the fabric smooth.
-
Fasten the zip or drawstring until it's snug but not straining.
-
Check the base. Make sure no gaps let rain run in.
Seasonal Care for UK Weather
Spring and Summer
Use the cover overnight and whenever you're away. Check the forecast on the Met Office website. A gusty day is a good day to take the canopy down and cover it.
Autumn and Winter
Clean the canopy with mild soap and water, let it dry completely, then cover it and store it somewhere sheltered. A garden shed is ideal if you have space. If you need one, take a look at the metal garden sheds available.
A Quick Tip for Wet Canopies
If you must cover a wet canopy, leave the hem loose so air can circulate, and dry it properly at the next chance.
Build the Whole Shady Corner
A parasol works best as part of a complete outdoor setup. A garden dining table with a parasol hole means the shade goes exactly where you need it. Add a set of garden chairs or a comfy garden sofa and you have somewhere lovely to sit all day.
If you'd like something more permanent than a parasol, a retractable awning or pergola gives generous shade and can be pulled back when the sun goes in.

FAQs About Garden Parasol Covers
1. What size garden parasol cover do I need?
Measure the closed parasol's height and its widest diameter, then choose a cover slightly larger than both.
2. Are parasol covers really waterproof?
Most are water-resistant or waterproof, but quality varies. Look for coated fabric and sealed seams.
3. Can I leave a parasol cover on all winter?
Yes, if the parasol is clean and dry first, and the cover has ventilation. Storing it under shelter is better still.
4. Will a cover fit a cantilever parasol?
Only if it's designed for one. Check for a side opening or zip that suits the offset arm.
5. How do I stop the cover blowing away?
Use the drawstring or straps, and fasten them snugly around the pole or base.
