I want to install an overhead watering system in my greenhouse 15'x8'. I grow mostly tomatoes,cucumbers and pot plants and wonder would it be suitable? I can only find one system in England ( wrong size) but no reviews. Help please.

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.

This is a most beautiful Camellia that has been planted in my garden for over three years. It is in a sunny south west facing spot. It has grown nicely since being planted and its foliage is glossy and healthy. The only problem is...is has never flowered. The label (long since gone) showed a red flower but I cannot recollect its name. Its foliage alone warrants it its spot in the garden but I really want to see it flower. Should I move it or is there something I can feed it that might encourage flowering?

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.
