    Deciduous.. for a reason?

    Sad, I know but I've been thinking a lot about composting, and natural things decaying/speeding things up recently and as I was raking leaves up I thought (it's probably wrong mind!!) it's it amazing, if deciduous trees shed their leaves to act as a natural mulch/compost?

    Anyone know the real reason why they do?

        And it makes a really good mulch and feeds lots of bugs and fungi too

              There is a bit more to it than just the 'rest time', because conifers are evergreen (most of them) and many of those grow in conditions too harsh for most deciduous trees. One reason trees shed leaves (conifers shed a few at a time all year) is to get rid of waste products, a bit like the vegetable equivalent of pooing, and we all know how good well aged poo is for plant growth!

                It is to reduce water loss through the colder season.

                  You mean the time of year when there are vast amounts of rain, except when things freeze??? OK so conifers lose less (needles don't have so many 'pores'), but they still lose some, and there are a lot of conifers much further North than most oaks and beech (silver birch grows even further north, and really fits the picture, most others, aren't such a good fit)

                  PS, of course most of these species lived through the ice age, when frozen ground was pretty near universal in winter. It's just interesting that they still do it when conditions are kinder, eg fig trees in Spain.....

                    Perhaps it's just that they know how beautiful they look in silhouette against a winter sky

                        Plants lose their leaves in winter as this is their dormant season.

                        However, it is also to reduce water loss. This may seem odd in the rainy winter, but when the ground is frozen solid for 2 or 3 weeks in a row it is pretty much the same as a summer drought- i.e. no access to water.
