Frogs can be very useful in the garden eating more than their share of slugs. On a warm day from February onward frogs and toads will emerge from hibernation, mate and lay eggs as spawn. Do not worry about too much spawns as one frog will lay up to 2000 eggs of which only half a dozen become adult frogs. If you get far too much spawn so that it is chocking the top of the pond you can transfer some to a bowl so you can watch the tadpoles develop over the next 6 weeks or so. Transferring spawn to another pond may transfer disease or unwanted plants. Toadspawn is formed in long strings rather than the clumped or bunched frogspawn. Newts put there spawn on the underside of leaves.
