Yesterday there were 11 distinct clumps of frog spawn in the pond and
I could see a fair few of the little luvvies inside wriggling a bit so
was expecting them to hatch over the coming week or so.

By this morning, though, the whole lot had hatched in one go and
they've somehow merged into two masses. The empty eggs have formed
themselves into two circles of gooey stuff around the two lots of
wrigglers. I can't see even a single unhatched one though there may be
some underneath the masses.

I've never known everything to happen all at once like this. Usually I
just leave them to their own devices but I'm now wondering if the pond
will sustain them all - I gave it a real clear out last year so
there's not that much for them to feed on.

I know some people use fish food and was wondering if there's a "best
type" to use and when I ought to start putting some in. There are no
fish in the pond.

I'm also wondering whether I should somehow break up the larger of the
two masses which is well over a foot in diameter (the smaller one is
about 6 inches) and is really a "solid" mass of babies, maybe by
twirling a stick around in the mass to give the ones in the middle a
chance to get out.

Any ideas welcome!

Their first food is the jelly they hatched from. You'll notice them
hanging on it and they will eat the lot.

I've seen our tadpoles eating the floating pellet type of pond fish

Congratulations! Hope you get lots of froggie friends to eat your molluscs.
As Janet says, they live off the very nutritious jelly that surrounds
them. As they get bigger, they will start to eat small pond critters
and drowned flies. I believe they also eat a certain amount of plant
matter. If you don't have pond plants (or if you do but you don't want
them eaten), try floating some lettuce leaf and see if they nibble on
that. I'm also fairly sure that, as they develop, they eat other
taddies, so you will find that a) there is enough food, and b)you won't
need to thin them out.

That's the problem. In previous years, the little wrigglies have
hatched on top of the jelly. But this year, and I've never seen this
before, several clumps have come together in a mass and all the spawn
seems to have moved to a ring around the outside. So the poor ones in
the middle don't have any jelly to hang on to.

And I think the (also unusual) mass hatching within a 24 hour period
rather than over a week or two might be a problem as the babies don't
have any unhatched spawn to feed on.

It may be because whilst the spawn was laid in its usual places, the
clear out last year means that there's more depth of water below the
spawn - it's not lying on top of planting baskets whose surface is
barely below water and so is more mobile.

At least I managed with some netting to stop the blasted magpies
pecking the spawn out of the pond before it hatched. Maybe that was a
mistake.

Still, I'll do what I can to give them (the taddies) a fighting
chance.

If I can get some decent photos later on I'll post them - so far I'm
getting too much reflection from that bright thing in the sky.

Meanwhile the cat's intrigued. He's spent hours today just sitting

and wonder if he realises what he's in for if a lot survive.

Didn't you have some frogs somewhere in your garden a while back? You
probably didn't get the ponds dug in time. But don't worry - if you
had frogs anywhere in the garden this year they will come back next
year and you may well find spawn then. It took a year or two before my
pond got colonised.

But once you get spawn, you won't look back. Frogs return to their
birthing pool to lay so if you get one lot of spawn in the first year,
you'll get 2 or 3 clumps the next and it grows from there.

I've got two clumps of frogspawn so far. The first was laid at night
on top of my water plants in my fishpond. I transferred them to my
little fishless pond as I feared for their lives when they hatch and
they were rather exposed to predators in that position.

This afternoon I watched two frogs mating in my fishpond and they have
laid the second clump of spawn mostly submerged and seem to be hanging
around, to protect them maybe? Anyway I have left those to fend for
themselves and there are places where they can hide when they hatch.

So its all looking good, my four fish have done well over the winter,
there are small newts around and now frogspawn. Can't wait for them to
hatch. So what happens should I get masses of tiny frogs, or will most
of them be killed or just die?

What I thought were bats on my night CCTV have turned out to be large
moths which trigger the motion detector.

Ah, yes. Understood now. That massing is wierd. One of Nature's puzzles.

Taddies and frogs do seem to intrigue cats. A previous cat used to play
tiddlywinks with frogs, but didn't harm them. Current cats are a bit
more feisty so, although I miss having frogspawn, I'm relieved of that
particular burden.

If your adult frogs get a bit peckish, I can always send you some of my
slugs .. very juicy they are!

No thanks. Once they get that big they can fend for themselves!

I did drop a small slug into the pond last year. The water boatmen
swarmed over it - I could almost see them biting chunks out of it
before a frog popped up and took it in one bite. I'll be checking
later in the week to see if I still have frogs in the pond - they'll
probably devour a lot of the taddies if there are. Usually by now,
though, they've moved back into the big heap of bark chips I keep
beside the pond for them. The other side of that heap are my hostas.
Never have a slug problem with the hostas!

The survival rate is, unfortunately, miniscule - maybe 3 or 4 mature
frogs from a load of spawn. They eat each other and other wildlife
loves them. It takes a few years before a frog is mature enough to lay
but somehow, the year after you've found spawn in a pond, older frogs
will find the place and once the original few get to laying stage
they'll be back as well and wahey! So you'll have increasing amounts
spawn each year after the first as long as you maintain the right
conditions. I've even read that if an old pond is filled in, it's not
unusual to find spawn laid on the ground where it used to be for a few
years.

Last year I'd drained the pond a bit at spawning time as it had to be
cleared out. Things got a bit crowded and one frog jumped out of the
pond and laid on the path beside it (with the cat and me watching
somewhat bemused) then hopped back in.

Bats are a mixed blessing. Noticed some flying round the house in
circles every summer night some years ago. On one or two occasions one
has flown in through an open window. Spoke to local bat people. Turns
out there are some males "nesting" in the cavity wall of the house.
Sensible creatures are bats! There's a roost of females down the road
in the church tower. The males fly down there for their bit of fun and
then leave the ladies to get on with the job whilst they return here
for some peace and quiet. I've been told that the number of males here
will never fluctuate. If an old one dies, a youngster will be invited
to replace him but any extras will be turfed out.

Downside is we can't get the cavity wall insulated. But that's a small
price to pay I think.

Then after a while they become cannibals. There may not be much for them
to feed on but only a few need to survive. Just leave them alone and the
froggy population balance will be maintained.

Nah, back lawn's currently crap, despite a lot of work over the last 2
years which has seen most of it lifted, the soil underneath dug over,
pumped full of grit to improve drainage, and then relaid or resown.
Looked lovely last year. This year, no weeds and very little moss but
the grass is sparse. Will soon be overseeding and feeding like mad.

The front lawns look good though.Tiny one was relaid completely last
year whilst the other's untouched original except where I've removed
shrubs to open it out a bit. I've noticed that whilst last year the
grass was all the same colour, the bits that were seeded when shrubs
were removed are currently darker than the rest. Weird.

As well as froggie (and hoggie) slug eaters, my secret slug deterrent
around the hostas is shredded CDs and DVDs. I offer to remove the
CD/DVD waste from offices on estates I manage and have a shredder that
pulverises them into confetti. These are scattered around the plants
like crushed eggshells. Plus points are that they don't decompose and
in the sun you get a multi-coloured glint shining through the plants.
And, of course, slugs and snails don't like the sharp edges. I can
also dig the shards into the ground whenever and they act like coarse
grit to improve drainage. There are lots of uses for unshredded CDs
and DVDs as well.
