I have a lovely white azalea that flowered profusely two yrs ago, and since then when it flowers it looks as though its withering at the same time as the flowers are brown/withered looking in parts,some have brown centres before flowereing! any ideas, it is otherwise healthy looking and is now reverted to all green leaves again after flowering has finished.

I have a tree peony about 3-4ft high which has about 3 flowers on it. It is positioned in a south facing border with little or no shelter-is this the best position for it? I have another one for years and it is north facing and very sheltered and not doing very well?

I'm wondering if it's safe to plant eucalyptus trees near (within a few feet of) a wall as I've heard that their vigorous growing root system can undermine foundations? If 2-3 feet is too close, how much space would you recommend? many Thanks!

I have yellow leaf on laural hedge was wondering if epsons salts would help the green back on to the leaf an would the epsons salts promote growth on the laural hedge.

2 years ago I planted 4 chaenomeles 'Jetrail' against a fence in a semi-shaded spot in my back garden. To date, only 1 has bloomed. Any ideas as to why the others haven't yet when conditions are the same for all 4? Do they need more time to establish themselves maybe?

I have a camellia with 5 or 6 years,but have no buds or flowers on it this year or last, had flowers on it for other years,was wondering what problem is and would I move it to another part of garden.

We have a damp area measuring 40 feet by 30 feet and were advised to plant Salix Alba Tristis here. On the internet we read that the roots can spread three times the distance from trunk to outer canopy. This seems huge. We think it was an American site. Will this hold true for Ireland? Is this tree suitable for us? Pauline P
