What should you do if you aren't sure if it's a weed or a flower?
In spring, it can be difficult to determine what is a weed and what is a flower, especially when things are just emerging. Do weeds have certain tell-tale characteristics that make them easier to identify?
Are they definitively different from plants we buy at garden centres?
What is your personal favourite weed and why?
I'm lucky. I get to spend most mornings strolling through my garden, coffee in hand, admiring my plants and pulling weeds that dare to raise their unwelcome heads. I find that weeding regularly makes gardening less of a chore and it's an effective way to stretch a little before breakfast as well.

Control: Prevent poison ivy with a deep layer of mulch. If the weed starts to grow in your yard, spot-treat it with an herbicide or wrap your hand in a plastic bag, pull the plant up, roots and all, and carefully invert the plastic bag around the plant, seal, and throw away.
