    I planted up some lobelia this year - some using coco liners, some using material type liners and some straight into stone planters.

    The lobelia planted in the coco liners have struggled to grow - whilst the others have thrived.

    The only difference I can see is that the coco liners let far too much water through - whilst the material type absorbs the water and the stone planters just don't let the water drain through.

    I was really looking forward to a good display this year from my 'obelisk/hanging basket' combo - but it didn't happen.

    Lesson for next year - use material type liners only - and see if this helps.

    You live and learn as they say :):blue thumb:

      When using Coir liners, I always use some bin bag plastic as an inner liner to retain moisture, just punching a few holes through it at the base for drainage.

      The Coir is for aesthetics, the bin bag plastic for practical purposes.

        Clanless, I am glad to read your post. The exact same thing has happened to me, but I wasn't smart enough to work out what the problem was! Scrungee - thanks for the tip. I really liked the look of coir, and this way I can keep using it :spinning:.

          Lobelia do like a lot of water and can struggle in baskets some times . As Scrungee I line my coir basket liner with a black plastic bin bag. When the basket is planted up I then trim the excess plastic off with a Stanley knife or scissors. I just punch 3 or 4 holes in the bottom with a long screwdriver to give some minimal drainage. The black liner also protects the coir so you may get 2 or 3 seasons from one liner.

            Tip for planting through plastic lining: If planting it up with plants all the way down to the base, cut small holes through the lining, carefully roll the plants up in a piece of plastic cut from bin bag, carrier bag, etc., gather the top of the plastic wrapping (that will project a few inches beyond the top of the plant) and feed it through from the inside until the soil/roots but up against the inside of the lining.

              The bin bag does the trick. Thanks for the tip!

                Harry, completely agree. My lobelia is usually lovely in a hanging basket, but this year it has been thin, weedy and late to flower in its coir basket. Hopefully y now I can keep the nice look of coir and have brimming baskets next year!

                  and...this is the result of my experiment with basket liners:

                  this basket is lined with cardboard only :frown::

                  Lined with cardboard.jpg

                  this is the basket with cat litter underneath the compost :smile::

                  Cat litter under compost.jpg

                  All plants grown from the same packet of seeds using the same compost and seed tray.

                  No plant food added - 3 holes punched in the bottom of each liner.

                  The baskets definitely take much longer to dry out.

                  The thicker rubble bags/inside out compost bags provide a more pleasing look to the outside of the basket.:spinning:
