Protects against mutant lawns!
Reviewed in the United Kingdom on 22 August 2018
We had a new lawn "installed" this year from turf that we laid at the end of April, just as the drought started. Yay.
We carefully put a small paved area around our bird feeders. Forethought! Yay. We even placed a few terracotta pots there to catch dropped seeds. Decor! Yay.
Birds don't care. They pick through the seeds in feeders searching for that perfect seed and chuck the rest, with some degree of enthusiasm I might add, around the local area. The pots catch a lot, the stones save a few from going onto the lawn, but a few still get there and have grown into some pretty weird things at times, and we don't want our lawn to be weird.
So we've gone to this "no grow" formula that hopefully will keep our grass looking grassy and classy. Part of the trick seems to be that there are a lot fewer whole seeds in the mix, if any - it is mainly non-germinating bits in there. This means in practice that there are some birds that no longer show up near the feeders for a couple of reasons.
The first is that there are some birds that really seem to want seeds; bluetits and other birds of that family don't come to the feeders half as much as they used to. There's also a lot less droppage and "chuckage" of food, which means that the ground feeders like robins and blackbirds don't come around to forage for the seeds that other birds have dropped. "Our" robins don't even use the feeders as they've been doing, so using this mix has altered the balance of the birds that use our feeding area. We're faced with the notion that the feeders will need to be for birds such as sparrows (that love the no-grow formula) and we'll need to lay down feeds for the other birds that drop by, because they're now a bit short-changed around here!
So yes, the no-grow mix works as advertised, but it will also change the mix of birds that drop by. Mixed blessings, I guess. Hopefully this review has been helpful, even if only giving some ideas about using paving and pots to catch debris!
Update: As the year ended we'd still not seen any problems with weird weeds growing in the area around the feeders, so I think we're in the clear so far as this seed goes. It's immensely popular with sparrows and robins, and even the blue/great/marsh/coal tits we get around here will come to the hanging feeders, especially when the weather gets a bit harsh. You will always need to vary the feeds available if you want a greater variety, but this does a great job for the more common garden birds. We're finding that our feeders, which spend most daylight hours occupied by several birds, get through a 20kg sack about every two months.
