Now listen here Jim - I told you about this one over on the UK forum. It was in the corner of your very first picture. ;-) I'm very upset you ignored me.... (US readers don't worry - I am just being SARCASTIC. Jim will cope.) It's a Phygelius, aka Cape Figwort, aka Cape Fuchsia, and it will not kill your apple tree. It spreads by runners and you'll just have to keep pulling and digging until it is gone. Until it flowers you will not know if you have the old Pc 'Coccineus' which goes rampant or one of the P aequalis cultivars which are yellow and, slightly, better behaved. Being in Torquay it'll be loving the climate in your garden.

Looks like grass to me. The easiest way to get rid of it is to smother it, though digging gives more instant results.

Here's another picture.

I use adblock plus on my mac in Firefox and I don't see any ads in Yahoo. When GW switched to Houzz, someone posted about adding "Styles" to make the page appear more like the old GW. I added something called Morning Glory. One of the benefits is it is blocking out all the new ads that Houzz is putting on the sidebar. I looked at GW in Safari where I don't have "Styles" added and the ads made me crazy. I checked on Firefox by turning off the "Style" and could see all the ads for Houzz. I couldn't get adblocker to block them. So I simply turned the Morning Glories back on. Oh, and I donate every year to AdblockerPlus because I appreciate it so much!
