Squareroot Planters

    Aluminium planters handmade in England

    Exceptional planters for exceptional spaces

  • Squareroot planters are handmade to order so each and

    every project is unique to its location.


    The planters are designed around the original Squareroot planting system and carry a lifetime guarantee on the aluminium structure.


    They are the perfect combination of beauty, function and engineering.

  • Planting system

    A series of interchangeable inner pots enables swift effortless seasonal changes to planting schemes. Alternatively the planters can be filled conventionally.


    Interchangeable inner pot system

    A tree container sits upon the lower rails. Two cradles are then positioned across the upper rails forming a platform for the interchangeable seasonal pots to locate.

    Conventional planting

    A sturdy slatted base is fitted, followed by rigid insulating panels in the walls of the planter. We recommend covering the base with planting felt, followed by a layer of drainage material, before filling with planting medium.

  • 'After spending months searching for our ‘perfect’ planters we found SquareRoot at the Chelsea Flower Show. From our very first meeting, to subsequent home visits we were utterly impressed with both directors, Simon and Karen – nothing was too much for them. Most importantly, we felt that they not only produced top of the range planters but genuinely cared about true customer satisfaction.

    The finished products are beautiful – and doubtless will outlast us. We recommend them wholeheartedly.'



    Barbara and Howard Moss, Bushey Heath, Hertfordshire



    'Delighted with my planters which are a 'head and heart' combination of beautiful to look at and so very practical. I can't wait to see them in the summer when the very clever planting system will come to the fore...'

    Ms. Pooley, East Molesey

    'I attach a photograph of your planters in situ – they look amazing.'

    Nick Lane Fox -  Bramham Park

    'We first came across Squareroot when we visited a friend’s estate in Yorkshire. We were quite blown away, not by the house or fabulous park, but by a selection of Squareroot planters waiting to be planted. Our host explained how they worked and we were hooked. Simon and Karen were both charming and meticulous. They came to visit us in Hampshire on several occasions and worked on various designs and shapes that would suit our simple family farmhouse. We are absolutely delighted with the finished product which has been blooming happily for a year.'

  • About Squareroot aluminium planters


    What are Squareroot planters made from?

    Our planters are 100% aluminium with stainless steel fixings. Many of the planters have a lead capping detail which has been treated with patination oil to slow the process of oxidisation.

    How do I move the planters?

    By removing the inner pots the weight of the planter is dramatically reduced and the planters can then be lifted into position.

    Why aluminium?

    Aluminium is non corrosive so we chose it for its longevity over a traditional wooden planter. It is also light weight making it perfect for roof terraces and balconies.

    How do I look after the painted finish?

    Both the wet spray and powder coated finish can be hosed down to remove any grit and dirt, if necessary use a mild detergent solution and a non abrasive cloth for stubborn marks

    Can I tailor the height and style of my planter?

    As all the planters are made to order they can be sized to fit your exact requirements. Similarly the planters can be built to accommodate irregular ground conditions such as slopes, lips and steps.

     I have large specimen trees which will need to be overwintered.

    Any of the capped leg or finial planters can be made with a detachable side panel. This means that large tree tubs can be removed easily, without disturbing the plant's root system.

    What colours are available?

    We can wet spray the planters in any colour and are happy to advise on our most popular colours. In addition, we now offer three sheen levels, gloss, satin and matt. If you are having the powder coated finish a RAL or British standard reference is required and come in semi-gloss or very low sheen level of 10%

    Can I buy extra inner pots?

    The planters all come as standard with two sets of inner pots. Extra pots are available from stock.

    How long will I have to wait before my order is ready?

    Our lead times are usually 4-6 weeks. but can increase to 8-12 weeks during particularly busy periods

    Do you do site visits and surveys?

    We are happy to come to site to measure and survey. Charges apply  which are redeemable against your planter order.
