Overhanging trees can fill a pool with leaves and twigs fast. Use a safe skimming routine, the right tools, and simple prevention tips.

A Safe Routine to Begin With
Pools situated beneath trees demand a bit more vigilance. The leaves, twigs and blossoms will clog the skimmer basket and impede circulation if left to it, not to mention muddying the water’s appearance. It is best to put in place a simple routine for pool care:
- Do your skimming after a windy day or first thing in the morning
- Make sure to empty baskets on a regular basis to prevent overflows
- Inspect the corners, steps and waterline for any leaf matter that has lodged there
- Have a yard bin or trash bag at hand so you are not carrying debris across the deck
When you are ready to open or take out the skimmer basket, shut off the pump first. Put on some gloves and eye protection as you would with any sharp or slimy refuse and refer to the equipment manual for guidance. Should you come across anything that seems unsafe, be it odd noises from the equipment or visible electrical damage, put a halt to swimming and put in a call to a pool professional.
Tools for the Job
In a yard with plenty of tree cover, a small flat net is no match for a deep leaf rake or a bag-style skimmer; they clear more in one go and save you the trouble of multiple passes. A telescoping pole is also handy for getting to the far side without having to lean precariously over the water.
For a thorough job, have these on hand: - A fine-mesh net to get at pollen and seed clusters - A deeper skimmer for the larger leaves - A brush for the waterline and steps - A lidded container for what you have raked up so the wind does not return it to the pool
Employ long, even strokes. Work from the far end toward where the circulation is strongest so the floating material comes together rather than being dispersed.
An Orderly Approach to Skimming
If the trees are shedding, work from the top down to get the new material before it sinks and becomes a nuisance. A sensible sequence is to pull large twigs and leaves from the surface, then turn off the pump to empty the skimmer. Clean the pump basket in accordance with the manual and give the corners a good brushing. Once done, let the system run as instructed.
Under no circumstances should one reach into operating suction or put a hand near moving parts. If a lid is under pressure or appears cracked, leave it and seek help.
Limiting What Falls In
While you cannot prevent a tree from shedding, you can limit its impact on the pool. Prune back any branches that overhang too much, or hire an arborist for the bigger jobs. When the pool is not being used, a well-fitted cover is useful during heavy leaf fall.
Also keep an eye on the hardscape and gutters to ensure runoff is not channeling leaves your way, and check the fence line for low-hanging branches after a storm.
Things to Steer Clear Of
Some practices only make skimming difficult and risk damaging your setup. Avoid using a net so small it simply shuffles leaves about, or skimming while the pump is on when you need to get at the basket. Do not let the skimmer fill to the brim, and do not force parts that are stuck. Small seed pods and blossoms can be clogs in the making, so do not overlook them.
Time for a Professional
There are times when it is better to call in an expert. If the water remains cloudy or stained despite your efforts, or if you have reason to believe there is an issue with the filter, valve or pump, get some assistance. The same goes for weak circulation or a basket that seems to clog with undue frequency.
Any sign of electrical fault or overheating means the pool is off limits until a qualified professional has made the necessary corrections and can advise on a plan for your property.
