Fallen Leaves Affect Pond Ecosystems

Fallen Leaves Affect Pond Ecosystems

Usually around the middle of October Long Island experiences peak fall foliage. And, as those who have deciduous trees nearby know, those colorful leaves eventually land somewhere not far from the trees.

For some, falling leaves might only require raking or blowing. But those who have a pond or water feature know the leaves left in the water can mean one messy clean up come spring.

Don’t worry that netting will ruin enjoyment of your pond. Granted, netting is not the most beautiful addition.

 

“However, it isn’t up that long. Just get it up before the leaves fall and then simply pull it out once they’ve all dropped,” says Dave. “Just be sure to tent the netting so that it doesn’t sag into the pond water when it’s weighted with leaves.”

 

 

Dave adds that if you are late in putting up the netting, you can always use a long-handle pond net to clear out the debris. It’s just much easier if you use a net.

Another good idea is to trim back and remove any dead foliage from the aquatic plants before or after you put up the netting. “This cuts down excessive organic material that might otherwise decompose in the water feature,” says Dave.

One of the plants that requires trimming is the pond lily. They are idyllic water plants but unless it is cut back to just about its base, it might droop over into the water. This is true of any other marginal plants you have around the edges of your pond.

Since some debris will make it into your pond no matter how hard you work, Aquascape Inc. recommends adding a cold water bacteria treatment, which has concentrated strains of beneficial bacteria that works well below 50 degrees (F).  Their expert, Dave Kelly, recommends adding it routinely to help maintain water clarity and quality.

There may be a little work involved, but the joys of autumn are well worth it. Fall foliage viewing, apple picking, and evenings beside fire pits while the kids roast marshmallows — all working up to the big day: Halloween — is a very small effort to pay.
