Is it too late now (mid-Sept) to take cuttings of geraniums and fuchsias to pot up for next year? When is the ideal time?
What uses, if any, can be made of spent potting compost, e.g that used to grow annual flowers in containers?
I have two Senetti plants whose leaves are covered in ugly, brown, wriggly lines. A look on the net tells me that this is leafminer fly, and most sites say that it is rarely that damaging to plants. However both senetti are now dying, and it looks like so many of the leaves are affected that the plant might not be able to photosynthesise properly.Is there any way of treating the plants at this stage or should I just chuck them? Picking off the infected leaves as suggested by some sites would mean almost all the leaves at this stage. I am also worried about the rest of my garden becoming infected.

I have built a container 8'x10"x10" to hang on south facing wall in my yard which is the sunniest part of my yard but is shaded from 3pm. I have been advised not to drill holes for drainage in the wood as it would weaken the structure. Really it is a large hanging basketWhat drainage would you suggest - gravel/plastic sheeting any use? Thank you!

I have been having problems with growing seedings in my propagator. They all die, they flop over and they have very thin stems and don't form their true leaves.
Gerry, I was wondering, is now the best time to sow summer bedding for seeds?
Hi Gerry, I planted a number of seeds trays two weeks ago today, and made the error of re-using some potting compost that I had in other trays that I used over winter, which had developted an algae/moss growth on top. As a result, a number of my trays contain the re-appearance of this alage like growth.The trays contain Lobelia and Antherinthums with another containning Geraniums.The Lobelia, sowed on surface, appear to be germinating. However, Im not sure how the algae growth will affect them, or with future watering what will happen.Can you advise Thanks Darren
