So long as your soil isn't too cold you can still plant bulbs but, if you get deer visiting they will happily eat the flowers of crocus and the like.

Try planting crocus, muscari, chionodoxa, winter aconite and other small bulbs and corms.

I've found overlooked tulip bulbs and popped them into the ground far later then this time of the year and they have bloomed well. I still have to plant all mine but most will be in pots. The second time around ones can take their chances in the ground.

There is a product called 'Grazers' available that we've had success with at our local garden centre. It comes as a liquid that you mix up to the right strength and spray on the plants you want protected. Might be worth a try. Phil J
