Can you please tell me what this flower is? It has returned again this year with no effort whatsoever.
Could you tell me what this plant is? Bought it in Amsterdam recently as a novelty it grows without soil or water.
I mistook the lily leaves and stems for ivy and chopped them down completely... what should I do to try and save the bulbs?
I'm trying to grow organic and to that end I'm looking to make my own insecticide. Quiet a few of the formulas I have come across on line specify either insecticidal soap or dishwashing fluid as part of the formulation. Can you recommend an organic version and supplier of either of these.
I was given this plant as a present = the giver does not know its name!! It grows to about 5 ft and has a pink flower. Can you tell me its name please. Thank you Brian
I am not an expert in gardening and I need your help. I have a corner area in my front lawn that is full of weeds, they are now attached to the black landscape fabric sheet underneath and when I try to pull the weeds I tear the fabric, I feel like I'm not getting anywhere. Is it better to lift up the black fabric completely and replace it with a new one or get rid of it? Is it better to cover with soil or chip woods? The area where I live is on a hill and it's exposed to wind and sun .The ground is hard with a lot of stones, very hard to dig.
We put sedum cuttings down on a roof 3 years ago, didn't realise we had to feed the sedum, waiting for the show of colour last year combined with a very dull summer, there is a lot of moss in place. We applied seaweed on it last autumn which I will do shortly again. Just wondering what type of fertiliser, could I use that won't harm the sedum but will reduce the moss, there is also a part were clover is growing. roof is north facing. found on nz website the ratio n12.6/ iron 8 and sulphur 1, can't find if sedum will thrive on this.
I took a snip last summer (pic attached ) and i potted it and it has bloomed but I've no idea what it is. Would you have any idea? There are 7 stems with only 1 little flower head.Also should I wait till May to plant out and lastly should I divide it now before planting out? Any advice would be great.
If I pinch out the main shoots of my Dahlia plants at 3 sets of leaves (18-20") to promote bushier growth, by how much roughly would this reduce the eventual height. I have a few tall varieties (40-48") but my site can get windy conditions at times. I have shorter cvrs but I would like to keep these tall ones. I have staked them but this looks ugly.
I was pruning yesterday and a stem from one of my plants hit against another one. The sap inside blew out and into my eye resulting in a chemicial burn in my cornea, I have been in the er dept of Beaumont most of the night and in the mater eye clinic today. They have identified the plant as Euphorbia. The pain is unbearable and I think I may have damaged my sight. I have never heard of this dangerous plant before and wonder how I can get rid of it safely, The hospital said it was the first case they had ever seen. Can you give me some advice please...
Do sweet pea need to have their center tips removed to make them spread out more?
The leaves on my Iris reticulata are extremely long, to the extent that they actually take from the display, its like looking at the flower through the bars of a cage. Can you tell me what may have caused this please?
My front flower bed is shaded and sheltered by a tall hedge. The front yard is north-facing. What can I plant for some colour and coverage that will populate the bed nicely for the summer and maybe next year too? Would a clematis climb up the hedge with very little sun?
Like everyone , my garden is very wet and soggy. I thought I had good colour in a bed I see from kitchen window, but Primula viallii and pasque flower have disappeared. Winter heathers? Perennial wallflowers? Mini daffs doing well. Primulas struggling
I have a Phygelius African Queen I believe. Planted in 2002 by now it has invaded the decking, grass and the rest of the bed, neighbour's garden. Cutting it comes back stronger and spreading more than ever. I need to remove or eradicate it somehow, but there is a lot of it. Really need your advice please.
