Black & Tayberries

I planted 2 blackberry plants and a Tayberry plant in early spring this year, more as a deterent for intruders than anything else (although Tayberries are lovely, hadn't had them before).

The leaves have suddenly gone very yellow on some of the branches. In fact a branch has either ALL yellow leaves or is pretty much ok. I did put fish blood and bone down when I planted them. I haven't added anything since. Oh yes, I said they suddenly went yellow but not sure how sudden. 2 weeks perhaps. The ground around them (about 1 mtr away) is very dry and cracked. I had mulched around the bases and its moist in there.

Any thoughts?

Thanks. It is probably nutrient deficiency, I didn't know that they wouldn't be established yet. I haven't been looking after them much, I thought they'd just grow like weeds.

I'll get some epsum(sp?) salts down? and water well for the near future.

Well they did a damn good job mellowmick. I don't know why they're not more popular.

Great view btw.
