mushermusher Posts: 389


When the ideal time of year to put a  multch down?, and what kind of multch should I use?.

theres Astilbes, Primroses various ferns. Good old Hosters and Marsh Marigolds growing there, thanks for your forth coming help.

    I use well rotted manure for mine usually, but also bark. For most of those plants it would be ideal. You can also just use a good layer of decent compost.

    Bark is quite attractive as a mulch and would also suit those plants well. image

  • I was pleased to read your reply Fairygirl, as I have just put the finishing touches to my bog garden today. I used wood/bark chip and it certainly does look good.  Photo to follow. We dug a huge amount of leaf mould into the soil before planting anything and hope that this will help to retain water too.

    We also have Astilbes, primrose/primula a few ferns and grasses, flag iris and geum rivale in the bog garden.

    Hi GD - how's the pond doing? image

    The only issue with bark is that the blackbirds like chucking it around, so you'll need to have a little fishing net if it gets into the water image

  • Loving the pond Fairygirl - I could sit for hours watching the birds, dragon and damsel flies, etc. but there is still work to do here, so perhaps next week we will have more time ......!

    We bought a mass of oxygenators, fresh start and all that, only for a couple of mallards to gobble them all up!  However we have a tiny pond further down the garden with far more curly wurly (well that is what it looks like) weed so we have moved some of that into the new pond.

    Yes, you are right the blackbirds do love the wood chip, scattering it everywhere - we have put an old branch between the bog and pond to try to prevent the chip ending up in the pond. I bought my OH a telescopic fishing net for his birthday - fishing could be his new retirement hobby!

  • imageimageSorry musher, but I just wanted to show how the wood chip looks on our new bog garden which has an Astilbe among other plants.  My one regret is that it getsin full sun, I would rather it had been in a shady area of the garden - so it does dry out quickly.  I may add more wood chip as this will wear down after a few heavy rain showers. Normally I would try to use between one and two inches thick, so all the ground is hidden plus an extra layer on top .

    Glad you're getting so much enjoyment from it GD. Lots of hard work and tension along the way!    image

    If you add plenty of leaf mould or manure after a good watering, or at the end of winter, that will help retain moisture and the sun will be less of an issue. You can then top dress with bark to finish it all off.  Most of those plants will be fine with some sun as long as they don't get dried out down below. image

  • Yes, thanks Fairy, we dug in leaf mould into the soil as we prepared it, to help retain the moisture - (plus we have about 10 big bags of leaf mould to use up!). We have a hose connection which snakes it's way down to the bottom of the bog garden under the soil.  The hose has small holes in it, so the water can seep out to keep the bog soil damp for a few days before connecting the hose again. There is a thick layer of gravel at the bottom of the bog and then the liner.  We read it all in the RHS water garden booklet. In a year or two the plants will have grown so much that we will have to thin them out.

    I think you've got it pretty well covered then GD image

    It'll look great in a year or two when it all starts to knit together. You're right - you'll probably be hoiking things out before too long!

  • Thanks Fairy, yes I am sure we have over planted.  I have contained a couple of the plants in large plant pots to try to prevent them from spreading too far, or at least they will be easier to remove completely by  putting them in large pots.  It was fun to do - a joint effort with OH and we are looking forward to the changes over the seasons.
