Border Plants along a back wall - Lavender, climbing sweet pea & other evergreen climber were thriving but now have stopped growing completely and leaves are eaten (not from edged but more lace like). I had replanted a rhododendron from other end of border closer to the affected side - would this have caused a problem? no evidence of bugs on leaves though.
I planted everlasting sweetpea seeds in March indoors. Planted them out in early July. Some of them are twelve inches tall attached to some trellis. I am aware that they do not flower the first year but my question is what do I do with them when the frost comes. Do I cut them closer to ground level and do I cover them?
This lovely plant is growing wild at the bottom of the garden and I'm wondering if I can move it into the garden proper.
this plant suddenly appeared; I think it may have hitch-hiked in on the Stipa it's right beside. It's about 3-4 ft tall, with sparse, lance-like leaves. Thank you!
I have two different types of stipa - feathertail and golden oats - can i divide these and when? also do they need feeding and when?
I am interested in growing medicinal herbs and of course ginseng is the holy grail of these. I am aware that the root can only be harvested after 10 years and that it tends to grow naturally in shady woody elevated areas, so my question(s) are can i buy the plant here and would it grow in say the wicklow mountains essentially planting it and walking away ?
Can I divide primulas in August?
Setting up a small wildflower patch in my city garden....thought it was pink cow parsley but might be pink hogweed. Very pretty...should I encourage it in my wildflower garden or get rid of ? How can I be sure it is hogweed ?
i have a large bed full of perennials that as they've grown i've realised are not in the correct positions i.e. taller ones in the front and colour combinations not working.. when could i take them all out and reposition them? i would also like to divide some of them while i have them out of the ground but this is not essential. many of the plants are only one or two years old.. CAN i actuallly divide them when they are still so young?
The second-last plant to identify in this garden, can you help?
We have been growing Hollyhocks for a number of years and they are a sight to behold , however, every year they get this horrible rust on the leaves - starting lower down and moving up, we usually remove the bad leaves, but can you tell us what we should do to get rid of this problem?
I have a herbaceous paeonia that does not flower. It is planted in a sunny well drained spot. The leaves are shrivelled with brown spots. Can you advise me please?
can hosta be divided in autumn?
My peony has finished blooming - its early August- and i wonder if it should be tidied up/pruned or should i leave it?
Can you id this plant for me please! I didn't plant it, but we got top soil from a garden centre last year and presume there was a seed there that's settled in well! It's about 4 ft tall now and popping seeds all over the place!
