What do you put on top of the soil for the bonsais and Desert Roses.?
With the plants inside due to the temps outside I am thinking of keeping any bugs away from the soil. Kentucky seems to have their lots of bugs right now. winter time is better as it is too cold. But they like to get into the plant soil. So, what would be the best topping for the soil?
I dont use any toppings, you have less control over the moisture of the soil,...small rocks can be simply removed, but sand !?
I know the problem with the fungus gnats only,.. if you keep an organic soil too moist .... but other Country = other bugs, gnats and problems ?!
When I pass on trees to beginners, I tend to put a layer of moler clay on the top. That is a very good help for identifying watering needs. Light red means that watering is needed and dark red means no need.
I would not think the moler clay can prevent any bugs in the soil or on the trees.
