1. what type of ground are they going in ?

2. how much are you watering ?

3. are you digging a deep enough hole ?

4. are you planting them past the rootball ?

Some love full sun some don't, most of the time depends on the age of the plant

There may be 2 problems here, that I can see with what you've wrote.

First, it's good to not fool with the roots. I also found out that they don't like that.

But what you should do, perhaps, is to amend the soil where you are planting the palm. Try to make the soil where the palm is going as close to the same as the soil the which it grew and is currently happy.

Usually, some soil, some sand, some vermiculite (spelling?), some compost. It REALLY NEEDS to be able to drain well. In other words, when you water, the water needs to move through the soil quickly (not sitting there) and not collecting at the bottom either.

I usually make sure that I dig the hole almost 2X as large as the root ball. Then I add the soil mix and place the palm on top. I pat down lightly (not pushing hard on the soil). The point is to get any air pockets out, but not make the soil too hard. Then I fill in the hold, adding some fertilizer as I go. I use a real Palm fert as well as Epsom Salts (unscented). Again, patting the soil down lightly to remove air pockets.

Removing air pockets is VERY important. Any place there is air, the roots are not touching the soil.

But once it's planted, some people say water every day. I dont buy into that. Too much water WILL CAUSE YELLOWING!

When we planted all of our palms (not including the one we transplanted last May) we did the above, then only gave deep waterings 2X a week, starting from the day of planting. They have grown strong and large.

Hope that helps.
