Yes, it's a little too early. We've been in a deep freeze here in New York for the past couple weeks. I made the mistake of sowing my carrot & beet seeds outside back when the weather was nice - they are cool weather crops....But not frozen! They are under a 2 inch layer of ice and I'll have to get more seeds. I would wait til at least 2nd week in April. Occasionally we'll get blizzards in April, but very rarely.

Depends where you live in the UK Garry, early April in south, mid April in north of England and late April, even early May, in parts of Scotland.

To be honest, combined weed and feed lawn preparations are pretty hopeless at eradicating weeds - a better option is to use a separate lawn food, granular or otherwise, and apply Verdone Extra liquid lawn concentrate weedkiller when the weeds are obvious and actively growing, usually end of May or June, if you've got obvious weed growth.

In trying to eradicate weeds with weed killers, we have inadvertently created the "Frankenstein" of all weeds.

When "Roundup ready" crops became popular in the mid 1990s, farmers were enamored with the genetically-modified seeds built to withstand glyphosate, the active ingredient in Roundup, the most popular commercial weed killer. But after years of constant exposure, certain invasive plants have also developed a resistance, leading farmers to use more of the chemical. In some cases, the weeds have grown completely tolerant to the chemical, giving farmers fits.

I thank the Lord that, so far, the UK and much of Europe does not grow GM crops - unfortunately, I suspect that may well not be the case for the UK in particular in the next few years, once we've left the EU.

Well you wouldn't use Roundup on the lawn anyway!

I'm tempted to Verdone mine early before all the celandines have seeded....they are certainly obvious and actively growing right now!

Why would you use Verdone, but not Roundup Stera?

Round up isn't a selective weedkiller like Verdone (which is specifically formulated for use on lawns) - it will kill the grass.

Verdone is selective for broad leaved weeds Paul, whereas glyphosate (the active ingredient in Roundup) will kill everything it lands on, which would be a bit annoying on a lawn!
Oops Bamboo, we crossed there - nice that we agree!

It's OK Steragram. I was looking for YOUR response. I don't use either of them and don't feel it's necessary.

Strictly speaking it isn't of course - but we have two takeover bids - celandines at this time of year when one lawn in particular is golden with them, and buttercups staging a takeover for the lawn at the back. I don't win but have to keep making an annual effort...they quickly take over if not kept in check. The celandines advance very quickly because they eject their seeds with some force. It takes such a long time to do the grass though that they don't get done as often as needed really.
