what to do tomorrow

In not so sunny sussex i was planning on doing the following tomorrow;

Plant rest of spring garlic and onion setts
Sow a couple of rows of carrot seed

Is that a good idea. allotment is not water logged ?

why do you mix the carrot with Spring onion?

Yes, but check the carrot seed packet for correct sowing times. Not all carrot seeds are sown now. I mix spring onion seed with my carrot seed 

But the onion sets will be ok?
I was hoping to get mine in this weekend along with some (rather late) garlic.

Metoffice say heavy rain all day tomorrow might as well go to work!

ive only managed to get broad beans in. I was all geared up for putting onions in this weekend but the rain has made the ground so wet it is too sticky to plant them. Im going to put them in modules and in then into the greenhouse until the ground dries up a bit.

Can't decide what to do about my onion seedlings. This time last year, they were hardening off outside in the daytime by now, but I don't know if that's a good idea with this old spell. But if I don't they're going to get a bit leggy and droopy if I keep them indoors. Could put them in the tunnel, but that's a long way from frostproof
