Raised bed cover buying guide

Updated: 21 October 2026

A late frost and a week of carrot fly are not the same problem. This raised bed cover buying guide is the order before you trust a star line: name the job, see what is in the box, check the centimetres, then read the hole size or the gsm. The [raised bed cover comparison](/hub/raised-beds-greenhouses-and-compost/raised-bed-cover) holds the ten listings. [Fleece versus insect mesh](/hub/raised-beds-greenhouses-and-compost/raised-bed-cover/sub/raised-bed-cover-fleece-vs-mesh) separates warmth from a pest barrier, and [insect mesh sizes](/hub/raised-beds-greenhouses-and-compost/raised-bed-cover/sub/raised-bed-cover-insect-mesh) is where a millimetre matters.

What job you are buying for

Insect mesh, horticultural fleece and a low pop-up are three purchases, even when the titles all say raised bed cover. Mesh is the barrier for carrot fly, cabbage whites and smaller insects when the holes are fine enough and every edge stays shut. Fleece, as the Royal Horticultural Society describes crop covers, takes the edge off a light frost by about 2°C and breaks the wind. It is a weak stand-in for a fine net. A pop-up here is mostly a seedling tent, 38–43 cm high on the GIONAR, Windspeed and Solkraes titles, so mature kale will press the roof. If you need frost and insects, buy two fabrics and swap them.

What is actually in the box

Pictures often show a tunnel. The parcel may contain only cloth. Haxnicks, 120 × 100 × 50 cm at £19.99, draws repeated UK reviews that only the net arrived, although the pictures implied a frame. OAHAO at £16.99 is a loose 2.5 m × 10 m sheet. You bury or peg it. The bullets do not add hoops. WYRJXYB at £22.99 states a 3 m × 9 m net plus six hoop sets and 18 clips. FuBegi at £19.99 states 30 gsm fleece, rods, connectors and clips. If a photograph and the parts list disagree, follow the parts list.

Size and height you can verify

Measure the timber, then read the title in centimetres before a packed-size row. CHEOAR’s title says 9 m × 3 m, while a technical row prints 944.88 × 33.53 × 30.48 cm. That is not a second sheet to add to 9 m. GIONAR’s title says 115 cm and the technical row says 145 cm. Windspeed’s erected title is 112 × 49 × 43 cm, and 15 × 10 × 2 cm is the folded parcel. Heekcaa is 120 × 30 × 45 cm, a narrow row, not a 1.2 m bed. A 50 cm Haxnicks cover will clear low carrots. It will not clear a summer cabbage that has hearted.

Hole size or gsm in numbers

Micromesh and ultra-fine are not measurements. The Royal Horticultural Society separates a fine insect mesh around 0.8 mm from a standard mesh around 1.3–1.4 mm. OAHAO states 0.8 mm. WYRJXYB states 0.8 mm × 1 mm. Haxnicks, Heekcaa, Ghligna, Solkraes and GIONAR do not print a millimetre hole, so a carrot-fly job is a guess until you can see the cloth. Fleece here is 30 gsm on CHEOAR and FuBegi. The Society puts ordinary fleece warmth at about 2°C. Do not turn a 30 gsm bullet into −3°C.

Where the remaining risk sits

Once the job and the box are clear, the remaining risk is the edge. Bury insect mesh about 5 cm and do not stretch the net. Fleece should roll back on a mild day, and flowering crops need bees.

Common questions

Do I need mesh or fleece for my raised bed?
Match the fabric to the week you are in. Mesh is the cover when carrot fly, cabbage whites or aphids are the threat, and only if you can read a hole size or accept that the listing does not give one. Fleece is the cover when you want about 2°C of shelter from a light frost and a windbreak, which is how the Royal Horticultural Society describes it. A 30 gsm sheet does not replace a 0.8 mm net.
Will a pop-up fit mature kale?
Not the low tents in this set. Solkraes is 38 cm high, GIONAR 41 cm, Windspeed 43 cm, and Ghligna and Heekcaa 45 cm, with Heekcaa only 30 cm wide. Kale that has stood up will press those roofs. A hoop kit near 84 cm, the WYRJXYB bullet, leaves more room, and you still raise the cover once the leaves fill it.
Does micromesh stop carrot fly if no millimetre size is printed?
The word micromesh does not tell you the hole. Haxnicks uses it on a 120 × 100 × 50 cm cover and prints no millimetre, while OAHAO states 0.8 mm and WYRJXYB states 0.8 mm × 1 mm. Reviews say the Haxnicks net keeps carrot fly and cabbage whites off when the edges are sealed, and that is still not a measurement. If the pest is why you are buying, prefer a listing that states the hole, then seal it.
How do I stop the cover blowing away?
Bury the skirt or weigh it. The Royal Horticultural Society suggests about 5 cm of soil over insect mesh, and the OAHAO bullets say the same thing in shop language: bury the edges or peg them so there are no gaps. A 250 g sheet will not pin itself. Pop-ups in this set rely on stakes, which only work if the stake is long enough for your soil and the loop is actually on the corner.
What if the frame in the photo is not in the box?
Read the parts list before you rely on the picture. Haxnicks reviews in this file repeatedly say only the net arrived. That is a known pattern on that ASIN, not a one-off. If the listing itself promised a frame and the parcel has none, you can reject within the short window under the Consumer Rights Act 2015. If the listing never included a frame, the honest fix is pegs or hoops you already own.
