15' is pretty close to a swimming pool for any type of tree. Regardless of it being evergreen or deciduous, any tree will drop old needles or foliage......it's what they do :-) And it's pretty much inevitable that these will eventually find their way into the pool with any passing breeze or even foot traffic. You may be better off erecting some sort of pergola or shade structure to deflect sunlight and keep the surrounding pool plantings low and unobtrusive.

If you absolutely must plant a tree, look for one that is evergreen. In general, these will produce less litter than one that is deciduous, although there is much variability even with these (i.e., pines are on the high side as far as conifers go and magnolias are just downright messy). Gordonia (loblolly bay) or loquat come to mind as being possible choices.

Well I could put the trees closer to the house. Just don't know how close is safe. Suggestions on how close to the house I can plant. I would prefer a tree that does not get over about 30 feet so I can control them with pruning.

Am I just crazy? Maybe but I need some trees as the house gets a lot of morning sun on the side of the pool. Pool is about 70 feet from the house.

How about Shantung maple by the house? It would thrive in your location. Grows fast. Not sure what I'd recommend by the pool if you want it to keep it clean. Palms?

windmill palms and sunscreens on at least the east and west facing windows in your house

We had a similar situation with Crape Myrtles by our pool. I hated to get rid of them, but they were way too large to move the the amount of leaves dropped in the pool was ridiculous.

That said, we went the Palm route. Not much shade, but I think them, along with the Bananas and other tropical looking plants we put in fit the spot perfectly.

We've had the best luck with CA Fan Palms.

Read up on these to see if any will do. Not sure all will grow in your region.

Bauhinia x blakeana
Cordia boissieri
Eriobotrya deflexa
Ficus carica
Firmiana simplex
Geijera parviflora
Palms
Diospyros virginiana
Stenocarpus sinuatus
Tabebuia chrysotricha

A few of these are fruiting but produce large fruits that are less likely to get into the filter.

Some years ago I was told to plant some kind of pine trees right next to my pool (2 metres away) to cover the wall, to give some private and cover the view to neighbours balcony.) and these trees would not cause damages to the pool not drop leaves, etc, As this area is very windy, today I have a big problem with the needles going into the pool. It is a constant headache as the filter needs to be clean constantly and the Kreepy Krauly is always stopping, etc,
I will include some pictures.
What type of pine tres are these and what can I do to stop the problem. The one tree at the end is drying up. Is it perhaps lack of irrigation?
Kindly advise.
Thanks

Doesn't foliage blow into pool from neighbor trees? It's a losing battle with an outdoor pool. You just have to have a reg and freq leaf cleaning routine, or else hv a screened in pool

If you want nice, small evergreen trees that won't litter your pool with Fall leaves:

Texas Persimmon
