Spring Pond Care


Preparing for Spring 

Spring has arrived here in New Orleans, where I live, so it's time for spring pond care. I know you folks who live in northern climes are still feeling some nip in the air, so you will wait a bit before prepping your pond for spring. 

But for us, we are excited that our fish are swimming around, our plants are poking green shoots above the water, our waterfalls have come back to life and we are relaxing out of doors in our wonderful spring weather. 

We cannot relax just yet, because our temperatures are still fluctuating as are yours. Just because you have a 70 degree F day does not mean that you can start feeding koi. They must not be fed until the pond water temperatures are stable at 55 degrees F at night. Remember, if you have a balanced pond and no koi, you never feed your fish. 

Things to Have 

Check your filter. It is clean? Even if it looks clean, it probably is not. So give it a good cleaning. If you have a biofilter, give it a kick start with a bacteria/enzyme product like Microbe-Lift PL to ensure a good bacteria colony starts to grow in your biofilter. 

Check your pump. Clean it up. Check all your hoses for leaks or cracks. Nothing is worse than coming home from work and finding your pond dry because a hose leaked and your pond is nearly dry. 

Make sure you have a dechlorinator on hand. You will need it. I know you think you won’t, but you will. Here’s what happens. You decide to top off the pump. The phone rings. Then you realize you need to get to the bank before it closes, so you dash out. While you are out, you decide to take care of a few more errands. You return home a couple of hours later. Oops!! Your yard is flooded and your fish are lying motionless at the bottom of the pond. Add dechlor immediately. Start the pump is it was not already running. 90% of the time, you can save your fish. 

Keep Microbe-LIft PL on hand for blanketweed or string algae growth. With warmer temperatures, algae begins to grow quickly. 

Check your nets. Are they useable? It might be time to replace them. 

It never hurts to have a few hose clamps in your pond drawer or on your pond shelf. Those rascally things always break when you don’t have any spares. 

Do you have spare pumps? If so, check them now to see if they still work. Often when a pump is stored out of water, seals can break, especially if the pump was in a freezing garage or shed. 

Things to Do 

If you have chemicals, fertilizers or fish food left from last summer, throw it away. Most likely they have lost potency or have become rotten. It’s best just to dispose of them and start over. 

If you have leaves or other debris in your pond, remove it now. As the water heats up, the debris begins to decompose, fouls your water and fish can die quickly. Spring is a great time to totally clean out your pond. Remove all water, all equipment, scrub the sides lightly (no soap), rinse, use a wet vac to get the last of the dirty water out and then replace everything. Your fish and plants will thank you for it. 

Check your fish for any illnesses or wounds. If your fish are still a big sluggish, leave them alone. They are not fully awake until the water temperatures are consistently above 55 degrees F. 

Within a couple of weeks after your water reaches 55 degrees F, you can start exchanging 10% of your water weekly. Pond water is the best fertilizer in the world. Pump it into your veggie or flower beds. Water exchanges keep nitrites from building up and keep your fish alive, healthy and happy. 

Check your water plants. Spring is a great time for dividing and repotting. Remember, do not use any soil full of organic matter. I have had my best luck with water plants by potting them up in sand. I do not fertilize any pond plants except water lilies. They grow fast enough utilizing fish waste without having those plants leaping out of their pots by adding extra fertilizer. If you have extra plants after you have divided them, you can give them to a neighbor or friend. Remember, though, that many water plants can grow in low, damp spaces in your garden. So if you have taro, umbrella plants, or papyrus, plant them in your garden. Be aware they are very, very invasive, so be careful where you put them. 

If you have lost some of your cover or floating plants, now is the time to replace them. Your fish are happiest with 1/2 of the top of the pond covered. That gives the fish a place to hide from predators and keeps them cool in the heat of the summer. It also keeps the blazing sun from helping algae grow in your crystal clear water. 

Water lilies will start to grow when the water reaches about 65 degrees consistently. If you removed them from your pond and stored the corms in damp sand, you can pot them up and put them in the water with the top of the pot about 6” below the water surface. Do not fertilize them until the first leaves reach the top of the pond. Then use an aquatic plant fertilizer. I use a tab that I can just poke into the sand. If I am out of those, I have used Job’s Tomato Spikes or lacking those, Job’s Tree Spikes. Take the tree spike, whack it with a hammer to divide into 4 pieces. Use one piece at a time. Throughout the summer, your lilies want to be fertilized at least once monthly. Do not over fertilize or you will be feeding algae as well as your pond plants. 

Things to Watch Out For 

Be careful as you are beginning to play in your pond again. Big Daddy bullfrog is snoozing between rocks lying in wait for a tasty fly. If you disturb him, he will jump and scare the pants off you.

Mardi Gras

Mardi Gras was yesterday in New Orleans. It was early this year and this gardener, for one is glad it's over. We saw 80ยบ weather yesterday and probably 60's today. It is time to think spring for pondkeepers in the South.
Before your pond water starts getting cloudy and threatens to get green, use barley straw either in liquid form, bales or pellets

Either of these products will keep your pond clear through spring and summer.

Southerners: Something to start thinking about: If your pond has debris on the bottom and your pond plants are brown rotting before spring growth, it's time to clean your pond. The fish are still dormant as are the plants, and the weather has not yet reached the 90's of the summer.
