    rootrainers_open_showing_rosemay_rootsRootrainers are so easy to use and make seed sowing a pleasure. Here is a whole host of Top Tips, to get the most out of growing with them.

    The Five Inch Rule
    If you prepare the ground well and place in plants with a five-inch deep mature root system, little should go wrong. Plants suffer no check and are deep enough to withstand most vagaries of weather.

    Rooting Cuttings

    Rootrainers are ideal for cuttings. Take your cuttings, dip into rooting powder and just insert in a cell.

    For Large Seeds

    When planting large seeds, such as beans, gently press the seed down into compost with your finger.

    Large Leafed Plants

    If using Rootrainers seed trays with large leafy plants use every other cell or use the Compact Rapid, which has been specially designed for this purpose.

    Fragile Plants

    Rootrainers are ideal for fragile plants, such as sweet peas.

    Emerging Seedlings

    As soon as seeds begin to emerge from the soil, remove lid or take trays out of the propagator. The Rootrainers lid cleverly becomes the drip tray.

    Small Seeds

    Small seeds can be first sown in seed trays and then pricked out into Rootrainers.

    White Fly

    One brassica grower claimed he had never suffered from white fly since he had used Rootrainers.

    Under Bench Heating

    Under bench heating will promote even quicker root growth, without inhibiting top growth.

    Cuttings and Pot Size

    Most cuttings benefit from a shorter pot to encourage early air pruning of the root system.


    Remember that as the season warms up you will need to water your plants and seedlings thoroughly to prevent drying out.

    Stem Cuttings

    Stem cuttings can be taken all year round but do best in Spring and Summer. If you use The Rooterpot you can be sure of success in ONE season.

    Planting Out Plug Plants

    Remember when planting out plug plants to make sure that the top of the soil plug is completely covered to allow the plant to seat.


    Water collected from a water butt should not be used to water seedlings. Use tap water which has stood for a couple of hours to allow the chlorine to disappear.

    Houseplants Love Aquarium Water!

    Don't throw the water from your aquarium away, keep it in bottles for your houseplants and watch them flourish.

    Lilies And Tulips

    Lilies and Tulips should never be planted together because they suffer from the same diseases.

    Planting Tulips

    Tulips should not be planted in the same spot for 2 consecutive years, but if African Marigolds are planted where the tulips have flowered there will be no problem in using the same spot again.


    Azaleas like acidic soil and it is a good idea to water them once in a while with a mix of 2 tablespoons of white vinegar to 2 pints of water.

  • The Flower Garden - Sweetpeas

    Growing Sweet-peas using Haxnicks RootrainersSweet Peas are an excellent early cut flower to grow and they thrive if you have a polytunnel. They are also very hardy and very easy to grow. They produce a good crop of long stemmed and sweet smelling flowers, whilst taking up only a small area of ground.

    Two sowings should be made, one in November for inside flowering and a second in January for outside flowering. The Deep (Sherwood) Rootrainer and the Rowplanter are ideal to sow into.

    Fill the cells of the Rootrainer tray with good multi-purpose compost and wet it thoroughly then sow one seed into each cell about 2cm deep. If you are using the Rowplanter, place the seeds 15cm apart.

    If you have a heated propagator then place the tray into it or else cover the tray with the propagating lid and leave until the first seeds emerge.

    At this stage the trays should be transferred to a bench in the polytunnel (if you have one), or they can be left in the greenhouse to slowly grow on. When the plants have three leaves, pinch out the tops so that the resulting side shoots become stronger and more vigorous than the main stem.

    In February/March they can be planted out in the polytunnel in double rows with the plants spaced 15cm apart. If you are using the Rowplanter, you will simply need to slide the rows into the prepared trenches.

    It will then be necessary to fix a vertical net to allow the plants to climb or alternatively to tie each plant to its own cane with sweet pea rings.

    All that is then needed is to water well and harvest the blooms regularly, not leaving any to form pods.

    As soon as the blooms become short stemmed, pull up the plants and replace with the summer crop.

    Remember that you can leave the plants in Rootrainers until the weather is warm enough to plant outside.
