phoenix robellini fertilization


gsn

Recommended Posts

I have question about fertilizing a quad robellini!

I planted this field grown tree in January of this year,it is doing great,growing and sending out new fronds,even after getting slightly burnt in the one freeze ,heavy frost we had this year on 2/14.

The first question is, when I fertilize this tree should I fertilize for a 1 trunk plant or treat it like it is 4 trees quanity wise?

The second question is, I planted it slightly above grade maybe 2 inches. I mulched around it with about 2 inches of cypress mulch.

I noticed the other day when checking for mositure,before watering,that the the surface feeder roots  (small roots) were all through the mulch and not below ground. the bigger roots coming off the trucks are going into the soil. Should I  remove the mulch and cover with a thin layer of soil before I fertilze,or just fertilize on top of the mulch?

thanks in advance for your responses

Hard to do much to offend a robellini. If it's growing fine leave it alone. Many Phoenix species seem to get surface roots, it's not a problem. I'm sure you can give a triple some extra fert, just make sure you spread it around, don't just make a narrow  ring of fert around the trunks.

These are very forgiving palms.

I was wondering the same thing - I have a triple that I put in the ground in May.. The only fertilizing I did was when I planted it - I put all kinds of S@#t in the hole with this palm - Manure, peat, gypsum, compost and that was it - nothing else... well , this thing has grown leaps and bounds since then, staying beautiful and green.

redant,

Thanks for the reply,and information.

I know this is a common palm,but I was just curious ,since it isn't a clustering palm ,but 4 individual palms planted together,if I should fertilize it as 1 palm or 4.
