Leaves, leaves & more leaves

OK, so I'm officially fed up with Autumn. At the bottom of the garden are a Poplar and a Sycamore tree, both are huge. At this time of year, they are dropping leaves constantly, but now they are dropping seed pods which Indi is taking great delight in eating. Not sure if they're poisonous (haven't seemed to have affected her so far) but I'm sure they're not good for her - especially the quantities she's eating! Will have to get the Garden Vac out tomorrow...again...
