Hi, Eglee, Whether you have to replant depends upon a few things: 1) How large is it and exactly how close is it to the pond? These are slow-growing plants so if it isn't right next to the pond, it will take a while to reach the liner. 2) I assume there are no holes in the liner. The roots won't seek water it can't detect and I doubt they will 'know' the water is in the pond considering how thick most liners are. 3) If planted correctly and watered sufficiently, the roots of this palm will grow down, not across. Now having said all this, once this palm is on the way to being a mature size (and I would guess you have a number of years before this happens) the roots, just by their size and structure, could disturb the lining by lifting it up. I don't think they would penetrate the lining if it is thick enough. Any chance you could post a photo? Kathy C
I have a "chamaerops humilis volcano" plant which I had planted in my garden near to a pond about 3 years ago and I was told recently that the roots could reach the lining of the pond and damage its structure because they goes in looking for water. Could you please let me know if this really could happen? Do I have to re-planted in other part of the garden further from the pond? I would thank you in advance for your advice.
