    I think they're probably Miracle Grow Slow Release plant food pellets - give one a squeeze - dare you :)

    Pete's right, Michael. Slow release food which is sometimes in compost.

    He's very naughty telling you to squeeze one... ;)
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...

    But I've bought Miracle Grow slow release plant food and they're like little pebbles, these things burst when squeezed?

    Definitely slow release fertiliser, miracle gro sell the fertiliser separately in large tubs too.

    Definitely slow release fertiliser. The shell is permeable and the liquid fertiliser it contains passes through slowly. You’re not the first to be puzzled by these ... it’s a pretty frequent query here. 😊

    I have just taken my begonias out of the pots for the winter. I found a large group of round yellow eggs next to the roots of each plant and nowhere else. The distribution did  not seem consistent with fertilizer

    Did you put the begonias in the pots yourself?
    In London. Keen but lazy.

    Although this is a couple of years later… 2022… these yellow ‘balls’ are actually worm eggs. Depending on worm species they contain between one to eight or so baby worms. They are found in compost bags because worms form part of the composting process. Certainly some companies ‘add’ fertilisers but in this specific case.. they are worm eggs and your very best friend(s)…

    Really? I think the majority are fertiliser pellets.  Worm eggs are slightly less yellow and not as uniform in shape...and more translucent.
