The best Flower boxes with trellis, compared.
Top pick: GiantexUK (300 L) Best value: CHEOAR (2-pack) – Highest value part among the listings that are not the top pick, at about £19.79 for a two-pack, with drainage unstated and flimsy-stick reviews. Updated October 2026.
A flower box with trellis is one planter and one climbing frame, bought for a UK patio, balcony, fence or small garden where the soil bed is already taken. You use it when a cordon tomato, cucumber, sweet pea or another climber needs a support you can tie into. Judge the soil box before the headline height. Listings often lead with 140–180 cm while the box is nearer 25–40 cm across. Drainage holes let water leave the base. A reservoir is an extra well, not a substitute for those holes. A sealed tray on a balcony holds water and adds weight. The frame should stay seated once the box is full. Choose a freestanding unit, or one fixed to a wall. A rented flat usually needs permission before you drill into the building. Thin timber can warp after watering. Plastic does not rot, and it can still crack. Count the rods before you add compost. How to match box, plant and drainage is set out in the [flower box with trellis buying guide](/hub/plant-accessories/flower-box-with-trellis/sub/flower-box-with-trellis-buying-guide).

Question 1 of 2
What do you need the frame for?
The GiantexUK long planter is about £44.99, measuring 235 × 63 × 102 cm and weighing 9 kg, stated as 300 litres or 0.3 cubic metres, with an open bottom and one trellis you can place in the middle or at either side. The bullets say 14 mm fir side panels and dovetail joints, and the finish field says painted. The star line is 4.7 from five reviews. Two written reviews, both from the United Kingdom, call it firm, easy and suitable for tomatoes, and neither states a complaint. A listing field says 220 to 240 volts and 50 hertz, and the bullets describe wood and a trellis, not a powered part. Five ratings is a thin sample for a 2.35 m bed. The open base means it is not a sealed trough you can stand on a balcony deck and expect to hold water in.
Pros
Cons
Best for: You want a long fir bed on soil or a prepared base, and you can live with five ratings.
Less suitable: You need a sealed box for a balcony, or a sample larger than five.
Specifications
Common questions
How does this planter drain?
The bullets describe an open bottom so water does not sit in the box. Has Drainage is Yes.
Can the trellis move?
The bullets say the trellis can sit in the middle or at either side.
Is it an electrical product?
A listing field says 220 to 240 volts and 50 hertz. The bullets describe fir wood and a trellis, not a powered part.
The Crevyteg seven-piece set is listed at about £122.88, 2.9 m wide by 1.6 m high and 25 kg, with three boxes the listing prints as about 16 × 16 inches. The material field says metal and polypropylene, while the bullets say a plastic trellis and plastic planters with weighted bottoms. The star line is 4.4 from three reviews. One UK review built a corner, liked the drainage options and said the box held a large volume of compost without bowing, then lost two clip-on trellis pieces to wind within three weeks. The other found the instructions in tiny print and still finished the build. A bullet also says 3, 4 or 7 screens in the same sentence, so the pack count is not settled on the page. The 300 litre compost figure is that reviewer’s remark, not a specification field. Empty, the kit is already 25 kg.
Pros
Cons
Best for: You want a patio screen, you have checked the wind, and you can accept plastic panels.
Less suitable: You need a metal lattice, a settled screen count, or more than three reviews.
Specifications
Common questions
What are the screens made of?
The bullets say a plastic trellis and plastic planters. The material field also lists metal and polypropylene.
Can you change the layout?
The bullets say two separate planter-and-trellis units or one continuous run.
How many screens are included?
Number of Items is 7. One bullet says 3, 4 or 7 privacy screens. The listing does not pick one figure.
MYMULIKE (2-pack) is the top pick in this set. The MYMULIKE HEI-1.65 is a two-pack at about £29.99, in reinforced PP and alloy steel, listed at 25 × 25 × 120 cm and 2.46 kg, with a 5 gallon claim in the bullets, a reservoir, drainage and a 48 inch trellis. A size line also says 145 cm for the two-pack. The star line is 4.2 from 184 reviews, and the first 40 written reviews on the listing are from the United Kingdom. Praise clusters on easy assembly, the reservoir for tomatoes, passion flowers, kiwi and sweet peas, and the chance to take the kit apart at the end of the season. Complaints cluster on flimsiness, a missing water tray in the second unit, a top that comes apart when the tower is moved, a warped base and missing pieces. The shape field says round while the dimensions are square, and the title says two while the pieces field says 1. It has the largest set of UK reviews in this comparison, and it still shows the joint weakness the cheaper towers show. The food-grade line on the PP is a bullet point, not a certificate on the listing.
Pros
Cons
Best for: You want two patio tomato towers and the largest set of UK reviews in this comparison.
Less suitable: You will move the tower once it is full of compost, or you need a wide wooden trough.
Specifications
Common questions
Does assembly need tools?
The bullets say no screws and no special tools, and that setup takes minutes.
Is the box round?
The shape field says round. The dimension lines are 25 × 25 × 120 cm.
What capacity is stated?
The bullets say a 5 gallon planter box with a 48 inch trellis on top.
The Outsunny 845-796V00ND is a wall-mounted fir rack at about £36, measuring 16 × 60 × 80 cm and weighing 4.5 kg, with three boxes, a back trellis, inner bags and drainage holes. The listing states a 3 gallon capacity and a clear varnish, plus a six-month line against manufacturer defects. The star line is 4.2 from 79 reviews, and the first 36 written texts are from the United Kingdom. Reviewers like the liners, the assembly and the look on a fence, including for strawberries. They also report wood that splits or buckles after watering, a broken piece on arrival, and paint that came away with the stickers. The page asks whether it can hold heavy plants and does not answer. At 16 cm deep it is a herb and strawberry rack, not a trough for a cordon tomato.
Pros
Cons
Best for: You can fix a rack to a fence or wall and you want shallow boxes for herbs or strawberries.
Less suitable: You need a freestanding trough, or a 30 cm depth for a cordon tomato.
Specifications
Common questions
Is this freestanding?
The mounting type is wall mount. The bullets say to attach it to a wall.
Does it include liners?
The bullets say inner bags with drainage holes. Included components list planters and a trellis.
Can it hold heavy plants?
The page asks that question and does not answer it. No maximum load is listed. The depth is 16 cm.
The GiantexUK 392GTX3OANR is a fir and metal planter at about £99.59, 90 × 45 × 180 cm overall, with the soil box stated as 85 × 39 × 25 cm and a weight of 9.5 kg. Drainage holes are in the box, the finish field says unfinished, and the style name is no hanging roof. The bullets say natural fir with reinforced metal connections. The star line is 4.2 from 25 reviews, and all nine written reviews on the listing are from the United Kingdom. They describe an easy build, including by older reviewers, a solid frame, jasmine and sweet peas, and use as a balcony screen. One buyer fitted castors so the feet stayed off the ground, and one says it may be less strong than it looks. No repeated defect shows up in those nine texts. The 180 cm figure is the trellis height; the soil is a 25 cm deep trough.
Pros
Cons
Best for: You want a tall freestanding fir trough for sweet peas or a light screen, and you can keep the feet dry.
Less suitable: You need a pressure-treated timber line, or more than 25 reviews.
Specifications
Common questions
How big is the soil box?
The bullets say the planter box measures 85 × 39 × 25 cm. The overall size line is 90 × 45 × 180 cm.
What is it made of?
The material field says fir wood and metal. The bullets say 100 per cent natural fir with reinforced metal connections.
Does it have a hanging roof?
The style name is No Hanging Roof, Dark Natural.
CHEOAR (2-pack) is the best value in this set. The CHEOAR TX-1 is a two-pack of black plastic towers at about £19.79, listed around 28 × 28 × 144 cm and 2.14 kg, with a reservoir and a trapezoidal trellis in the title. Written reviews on the listing are from the United Kingdom, and they split between an easy build with strawberries or tomatoes and sticks that feel flimsy. One review describes a collapse, another a missing long pipe, and one says the pot is no use for heavy tomato plants. A June 2026 review puts the pot at no more than £5 to £10. Drainage holes are not stated, and Number of Packs says 2 while Number of Items says 1. At 4.0 from 62 reviews it is a cheap pair if the crop stays light, and a weak bet once the plant gets heavy.
Pros
Cons
Best for: You want two light towers for a small crop and you will not load them with heavy tomato plants.
Less suitable: You need a frame that UK reviews treat as strong enough for a heavy tomato plant.
Specifications
Common questions
Does the listing include a trellis?
Yes. The title and the bullets describe a planter box with a trellis, and the title calls the trellis trapezoidal.
Is there a water reservoir?
The bullets say the planter has a water reservoir at the bottom. Drainage holes are not stated.
How many are in the pack?
The title, the size line and Number of Packs say 2. Number of Items says 1.
The JQTOP PlantC01 is a single black planter at about £14.49, weighing 1.24 kg, with a trellis in the included list, drainage marked yes, and a siphon in the bullets. One size line is 25 × 147 × 25 cm and the title says 58 inches, while another line says 10 × 10 × 10 cm. The star line is 3.9 from 80 reviews, but only eight of the first 40 written reviews are from the United Kingdom. Those UK texts praise drainage and an easy build, and they also describe a frame that falls apart, poles that need tape, and a tower that collapses once the tomatoes grow. One reviewer puts a brick inside to steady it. The usage field says Indoor while the title says outdoor and indoor. Treat the 10 cm cube as a listing conflict until you measure the box that arrives.
Pros
Cons
Best for: You want a cheap single with drainage stated, and you will brace the frame before the plant is heavy.
Less suitable: You want a size line that agrees with itself, or a frame UK reviews leave standing through a tomato crop.
Specifications
Common questions
Does it come with a trellis?
Yes. Included components lists a trellis, and the title is a planter box with trellis.
Can the listing be used indoors?
The usage field says Indoor. The title says outdoor and indoor. There is no separate answer paragraph.
What size does the page state?
One line says 25 × 147 × 25 cm and the title says 58 inches. Another line says 10 × 10 × 10 cm.
The MQJIAZHI planter is a green HDPE and metal tower at about £13.99, listed at 40 × 30 × 142 cm and 3.15 kg, with cotton ropes, a drainage hole and a title that says a metal trellis. The included list names gloves, a ribbon, five clips, three ropes and two decorative heads. The capacity field says 1.67 cubic metres, which the listing does not reconcile with a 40 × 30 cm footprint. The specification block does not answer whether wheels are included. The star line is 3.7 from 66 reviews, and 29 of the first 35 written reviews are from the United Kingdom. Those texts describe wheels that do not fit or come off, rods that need the coating cut away, and at least one buyer who expected metal and received plastic. It is the cheapest single in this set, and the extras in the box are not the same as a frame that stays put.
Pros
Cons
Best for: You want the lowest price for one rope-wick tower and you will check the rods before you add compost.
Less suitable: You are buying it for wheels, or because the title says the trellis is metal.
Specifications
Common questions
Does the listing include wheels?
The page asks the question. The specification block does not answer it. UK reviews describe wheels that do not fit or come off.
How does the self-watering work on this listing?
The bullets say cotton ropes in the base supply water. Three absorbent ropes are in the included list.
What capacity is printed?
The capacity field says 1.67 cubic metres. The dimension line is 40 × 30 × 142 cm. The listing does not reconcile the two.
The GarveeMore kit is a seven-piece planter and privacy screen at about £149.99, listed at 294 × 160 cm and 25 kg, with boxes of 40 × 40 cm. The title says a metal trellis and drainage holes, and the bullets say you can build one long run or two separate units. The only written review, from the United Kingdom on 10 June 2026, says the description is misleading: the panels are plastic, and only the poles are metal, covered in plastic. The star line is 2.0 from that single rating. There is no second UK text to check the weighted-bottom claim. At this price the kit is a screen first, and the material in the title does not match the one review on the page.
Pros
Cons
Best for: You already know you are buying plastic panels on covered poles, and you have checked the load for a 25 kg empty kit.
Less suitable: You are paying about £149.99 because the title says metal, or you need more than one UK review.
Specifications
Common questions
What is the trellis made of?
The material field says metal and plastic. The only UK review says the panels are plastic and only the poles are metal, covered in plastic.
Does the title mention drainage holes?
Yes. The title says the kit has drainage holes. The bullets also describe a weighted bottom.
How is the kit meant to be arranged?
The bullets say you can build one long planter with a continuous trellis or two separate units.
The GiantexUK UK-4631NA-GT is a freestanding wooden planter at about £44.59, 61 × 30 × 121 cm, with an interior box of 58 × 27 × 22 cm, a slatted base and a weight of 4.5 kg. The material field says fir wood and the bullets say natural pine, so the timber name is not settled on the listing. The bullets also describe a removable base plate and a rounded dome for vines, beans and cucumbers. A user manual is stated and the parts list is not. The listing has no Customer Reviews line and no written texts. Until a UK star line appears, you are buying the printed dimensions, not a checked build. The 22 cm interior depth is the soil figure to use, not the 121 cm overall height.
Pros
Cons
Best for: You want this exact footprint and you will accept a listing with no UK review texts.
Less suitable: You want a star line, or a timber name that the listing states only once.
Specifications
Common questions
What wood does the listing name?
The material field says fir wood. The bullets say natural pine. The listing does not say which is correct.
How does it drain?
The bullets describe a slatted base with drainage openings and a removable base plate.
Is there an amazon.co.uk star line?
No. The listing has no Customer Reviews line and no review texts.
Ten amazon.co.uk listings are scored from the star line, the review count, how well the listing works as a planter with a trellis, and price only after that fit. Shelf prices, stars and review counts were checked on 19 October 2026. There is no laboratory test. A missing star line scores 0. The top pick is MYMULIKE (2-pack). Best value is CHEOAR (2-pack), which has the highest value part among the rest.

Start with the plant, then the soil box, then whether water can leave the base. A plastic tower with a well, a wooden trough and a privacy screen do not do the same job. Headline height is the frame, not the compost. Shelf prices in this capture run from about £13.99 to about £149.99. The top pick is the MYMULIKE two-pack. The best value is the CHEOAR two-pack. Nothing on this page is a laboratory test.
A flower box with trellis is one planter and one climbing frame. In a UK garden, patio or balcony it is what you buy when the ground is already planted, or when there is no soil bed, and a climber still needs something to tie into. The usual split is a light plastic tower with a water well, a wooden trough with a back grid, or a modular run of panels that is a screen first. A bush tomato or a herb pot does not need the frame. A cordon tomato, cucumber or sweet pea does.
The tall number is the frame. The roots only get the soil box. Listings in this category often lead with 140–180 cm while the box is about 25–40 cm across. A 16 cm wall rack will not take a cordon tomato that the RHS sizes at 30 cm or more.
Almost every kept listing needs assembly. Count the rods dry, then add compost. UK reviews describe towers that come apart once they are moved full, and sticks that feel flimsy once the plant is heavy. Do not drag a full tower across the patio.
A UK review of one privacy kit says the panels are plastic and only the poles are metal, covered in plastic. Another buyer expected metal and received plastic. Read the material field and the bullets together. Plastic lattice is not a metal trellis because the title says metal.
Name the plant before the brand. A cordon tomato, cucumber or sweet pea needs a frame you can tie into. A bush tomato or herbs do not. The Royal Horticultural Society asks for at least a 30 cm pot per tomato, or 35–45 cm between plants in a trough, plus a tall support and even moisture for a cordon. The British Clematis Society asks for at least 46 cm across and deep. A shallower box is a herb or strawberry rack, not a clematis trough. Read the soil box, then the headline height.
Judge the frame from UK review texts, not from the word sturdy. The complaints that repeat are poles that miss the holes, clip-on grids that come off in wind, and towers that come apart once you move them full of compost. Wood can warp or split after watering. Metal in a title is sometimes plastic lattice on covered poles. Assemble dry, count the rods, and only then add compost. Decide freestanding, wall-fixed, or a run of panels.
Three typical situations, each with a recommendation from this comparison.
You want a reservoir and a frame for one or two tomatoes on a patio. MYMULIKE (2-pack) at about £29.99 is the top pick: two towers, drainage marked yes, 4.2 from 184 reviews, and the largest set of UK reviews in this comparison. Those reviews still describe flimsy joints. Skip it if you will move the tower once it is full, or you need a wide wooden trough.
You want a freestanding fir trough for sweet peas or a light screen, and you can keep the feet dry. GiantexUK (180 cm) at about £99.59 lists a soil box of 85 × 39 × 25 cm under a 180 cm frame, with 4.2 from 25 reviews. Nine UK texts on the listing do not repeat one defect. Skip it if you need more than 25 reviews, or a pressure-treated timber line.
You are screening a patio and you can accept plastic panels rather than a metal lattice. Crevyteg (7-piece) at about £122.88 is listed at about 2.9 m by 1.6 m and 25 kg empty. One UK review liked the boxes, then lost two clip-on pieces to wind within three weeks. Skip it if you need a settled screen count, or more than three reviews.
The top pick is MYMULIKE (2-pack), at about £29.99. It scores 72: 4.2 from 184 reviews, a reservoir, drainage marked yes, and a 48 inch trellis in the bullets, with the largest set of UK reviews in this comparison. Those reviews still describe flimsy joints and a top that comes apart when the tower is moved. The best value is CHEOAR (2-pack), at about £19.79, the highest value part among the rest. It is 4.0 from 62 reviews, drainage is not stated, and UK texts call the sticks flimsy for a heavy tomato plant. None of these scores is a laboratory test.
CHEOAR (2-pack)
Highest value part among the listings that are not the top pick, at about £19.79 for a two-pack, with drainage unstated and flimsy-stick reviews.
