This was a spiny stick that my daughter-in-law prised apart from the day lilies we were digging up to give her mum three weeks ago. As you can see, she didn't manage to extricate all the day lilies. She plonked it at the back of the garden, scattered a bit of earth around its roots and neither of us bothered to water it. She said she thought it might be quince. 

I've just found this in Wikipedia: 'Quince is a hardy, drought-tolerant shrub which adapts to many soils of low to medium pH. It tolerates both shade and sun..., does not require much maintenance, and tolerates years without pruning or major insect and disease problems.' My sort of plant!

At midday my package of stainless steel wire rope, loop clamps and turnbuckles (ordered after I read up on how to make a trellis properly and took back all the things I'd wrongly assumed I'd need) so I worked on the next stage of my trellis. It involved a lot of drilling, hammering and screwing from the top of the stepladder at a height I don't like, but I took deep breaths and got on with it, taking a break for a cycle-ride to the dump with clay, broken flower pots and soggy bricks.

The trellis is all metal and looks rather industrial at the moment but it will be fine when it is robustly holding up climbing plants.

In fact, I'm so pleased with it that I've ordered more bits to make another one along the garden fence.
