Join us as we uncover the secrets to maintaining a healthy, vibrant water garden through autumn and beyond. Let's embark on this seasonal journey, celebrating the unique beauty that fall brings to our aquatic landscapes!
Understanding Your Water Garden's Fall Needs
As summer fades, your water garden begins a natural transition. Understanding these changes is key to providing the right care:
Water Temperature: As air temperatures drop, so does your pond water. This affects everything from plant growth to fish metabolism. Pickerelweed and Duck Potato, being native plants, are well-adapted to these temperature fluctuations but still require attention.
Daylight Changes: Shorter days signal plants and animals to prepare for winter. You'll notice your Pickerelweed and Duck Potato slowing their growth and potentially starting to die back.
Organic Matter Increase: Falling leaves and dying plant material can affect water quality. This is particularly important to manage around your marginal plants like Pickerelweed and Duck Potato.
Ecosystem Shifts: Beneficial bacteria slow down, potentially impacting the pond's balance. This can affect the nutrients available to your plants.
Recognizing these changes allows you to adapt your care routine effectively, ensuring a smooth transition into the cooler months for all elements of your water garden.
Essential Fall Care Tips for Your Water Garden
1. Managing Falling Leaves
Fallen leaves can wreak havoc on your pond's ecosystem if left unchecked. Here's how to manage them:
Install pond netting before leaves start to fall. This prevents most debris from entering the water and settling around your Pickerelweed and Duck Potato.
Regularly skim the surface with a pond net to remove any leaves that slip through.
Consider using a pond vacuum for thorough cleaning if a significant amount of debris accumulates, especially around plant bases.
Create a routine of checking around your marginal plants like Pickerelweed and Duck Potato, as leaves can easily get trapped in their foliage.
Remember, decaying leaves can alter water chemistry and deplete oxygen levels, so diligence is key to maintaining a healthy environment for your plants and fish.
2. Aquatic Plant Care
Fall is a crucial time for your aquatic plants, especially for marginal plants like Pickerelweed and Duck Potato:
Pickerelweed (Pontederia cordata): As temperatures cool, Pickerelweed will begin to die back. Trim yellowing or dead foliage to prevent it from decomposing in the water. In colder regions, consider cutting it back to just above the water level.
Duck Potato (Sagittaria latifolia): Also known as Arrowhead, this plant will also start to die back in fall. Remove dead or dying leaves and stems to keep the water clean. In milder climates, it may remain semi-evergreen.
Other Marginal Plants: Treat similar to Pickerelweed and Duck Potato. Cut back dead foliage to prevent decay in the pond.
Tropical Water Lilies: These non-hardy plants need special care. Either treat them as annuals or bring them indoors for the winter.
Hardy Water Lilies: Trim yellowing leaves and move plants to deeper water to protect them from freezing.
Submerged Plants: These oxygenators can often be left in the pond but may need thinning to prevent overgrowth.
3. Fish and Wildlife Considerations
Your aquatic friends need special attention as temperatures drop:
Gradually reduce fish feeding as water temperatures cool. Fish metabolism slows, and they require less food.
Stop feeding completely when water temperatures consistently stay below 50°F (10°C).
Ensure there are plenty of hiding spots for fish to shelter during winter. The roots and stems of Pickerelweed and Duck Potato can provide excellent cover.
Consider adding a pond de-icer to maintain a small opening in the ice for gas exchange.
Don't forget about wildlife! Many creatures may depend on your pond for water. Maintaining your water garden, including native plants like Pickerelweed and Duck Potato, can provide a crucial resource for local fauna throughout the fall and winter.
4. Water Quality Maintenance
Fall brings unique challenges to water quality:
Test water parameters regularly. pH, ammonia, and nitrate levels can fluctuate with increased organic matter from dying plants and fallen leaves.
Consider adding cold-water beneficial bacteria to help maintain balance as temperatures drop.
Continue to use a pond skimmer and filter to remove debris and maintain clarity.
If you have a UV clarifier, you may be able to turn it off as algae growth slows in cooler temperatures.
Monitor the areas around your Pickerelweed and Duck Potato, as decomposing plant matter can affect local water quality.
5. Equipment Check and Winterization
Prepare your equipment for the season ahead:
Clean and inspect pumps, filters, and plumbing. Repair or replace as needed.
Decide whether to keep your pond running or shut it down for winter. This often depends on your climate and the types of fish and plants you have.
If running through winter, ensure your equipment can handle potential freezing. Consider adding a pond heater or de-icer.
For waterfalls or fountains, check for any leaks or damage and repair before winter sets in.
Adjust the flow of your pump to prevent ice formation around marginal plants like Pickerelweed and Duck Potato.

Pickerelweed is a versatile and attractive marginal plant that adds vertical interest and beautiful purpleblue flower spikes to your water garden. Here's how to care for it in fall:
Pruning: As flowers fade and leaves yellow, cut back the stalks to about 2-3 inches above the water level. This prevents decomposing matter from affecting water quality.
Winter Prep: In colder regions, cut back all foliage and consider moving the plant to deeper water to prevent the roots from freezing.
Division: Fall is an excellent time to divide overcrowded Pickerelweed. Replant divisions immediately or store them in a cool, moist place until spring.
Wildlife Value: Leave some seed heads for birds, as they provide valuable food sources in fall and winter.
Duck Potato (Sagittaria latifolia)

Also known as Arrowhead, Duck Potato is a hardy native plant that provides excellent cover for wildlife and adds unique arrow-shaped leaves to your water garden. Fall care for Duck Potato includes:
Foliage Management: As leaves yellow and die back, remove them to prevent decay in the pond. In milder climates, the plant may remain partially green through winter.
Tuber Care: Duck Potato produces edible tubers (hence the name). In fall, these tubers store energy for next year's growth. Avoid disturbing the soil around the plant base.
Winter Protection: In harsh winters, consider moving plants to deeper water or adding a layer of mulch over the crown if in shallow water.
Propagation: Fall is a good time to harvest and replant tubers to expand your Duck Potato population.
Both Pickerelweed and Duck Potato play crucial roles in your water garden ecosystem. They help filter water, provide shelter for fish and amphibians, and offer food and habitat for various wildlife. By properly caring for these plants in fall, you're not just maintaining your water garden; you're supporting a whole ecosystem.
Preparing for Winter Dormancy

As fall progresses, it's time to think about winter:
If keeping the pond running, install a de-icer or aerator to maintain an opening in the ice.
For ponds being shut down, remove pumps and filters, clean thoroughly, and store in a frost-free location.
Protect marginal plants like Pickerelweed and Duck Potato by moving them to deeper water or adding mulch around the base, depending on your climate severity.
Consider adding a layer of clay balls or pea gravel over the bottom of the pond to provide insulation for hibernating frogs and protect plant roots.
In regions with harsh winters, you may want to remove and store tender marginal plants indoors, but hardy natives like Pickerelweed and Duck Potato can often remain in the pond.
Common Fall Challenges and Solutions
Be prepared for these common fall issues:
Algae Blooms: A final algae bloom is common in fall. Maintain your filtration and consider adding barley straw extract to naturally combat algae. Healthy marginal plants like Pickerelweed and Duck Potato can help compete with algae for nutrients.
Temperature Fluctuations: These can stress fish and plants. Maintain consistent temperatures with a pond heater if necessary. Native plants are generally more resilient to these changes.
Predators: With less foliage cover, fish may be more vulnerable. Ensure plenty of hiding spots and consider adding pond netting. The roots and stems of Pickerelweed and Duck Potato provide excellent shelter.
Plant Die-Back: As Pickerelweed and Duck Potato begin to die back, monitor water quality closely and remove dead plant material promptly.
Planning for Next Spring
Use this time to reflect and plan:
Evaluate your water garden's performance this year. How did your Pickerelweed and Duck Potato fare? What worked well? What could be improved?
Consider any additions or changes you'd like to make next season. Perhaps you want to expand your native plant collection or create more depth variation in your pond.
Start a maintenance calendar for the coming year to stay on top of seasonal tasks, including care for your marginal plants.
Research new plants or features you might want to add in spring to complement your existing Pickerelweed and Duck Potato.
Plan for any divisions or relocations of your marginal plants that you'll want to do in early spring.
