Our young Koi show took place at Reeds and Rocks. Many beautiful young koi were shown by their owners, and many will have a great future at shows ahead when they are more mature. Charlie and myself judged this show, we had great fun doing it and it was also a good learning experience for both of us. You will see a complete list of the winners in this newsletter.

OK, plants and fish. The easiest pond to take care of is one that contains a balance of both plants and fish. Both are really necessary to eliminate many problems and to enhance your enjoyment of your efforts. If you have a pond with only fish, you're going to have to work harder to keep your water crystal clear. If you have only plants, you really have nothing more than a pretty mosquito factory. A well-balanced pond doesn't need much more from you than a little cleaning occasionally. It’s when you start adding stuff that you can’t take out that you get into trouble. I talked about that in previous pages so I don’t have to repeat THAT sermon!

The first plant to appear in your pond is algae. If I get 100 e-mail questions a day, half of them will be about algae. What's funny is that it's not that difficult to control. There're hundreds of kinds of algae but for our purposes, they fall into 3 main categories, single celled or floating algae, string algae, and for want of a better term, slime. Slime is actually a good sign. A good coating of slime algae on your sides and bottom, your pond of course, is a sign of a healthy pond. If you ever drain and clean your pond, don’t scrub this algae off.

Single celled algae is the worst problem if your goal is to have crystal clear water. You won’t be able to get rid of all of it, and in fact you don’t want to as it’s food for many lower life forms, but you can minimize it. You can use chemicals to get rid of it, but you are only treating symptoms, not the cause. As with any other plant, algae needs water, food and sunlight to grow. You control it by controlling it’s sources. You can’t get rid of the water and still have a pond, so we’ll talk about the other 2 sources. The food feeding your algae is typically from one of 3 sources, decaying plant material, fish poop, and nitrates from your biofilter. The decaying material is easy to take care of. Once every week or 2, I run a pool net over 1/3 to 1/2 of my pond bottom, scooping up the muck there. That's a pool net, the deep kind, not a leaf skimmer. I dump it on my garden plants and they love it!!! I also stir up the rest of the muck on the pond bottom to be sucked up by the pump to be eliminated by the filtrs. I also make sure any dead pond plant leaves and spent blooms are cut off at least once a month to keep them from ending up on the pond bottom.

The other way to control the nutrients is to have other plants in the pond that will also use the nutrients.The plants that do this best are the oxygenating plants and grasses. There are many different types of these, but the most common you will see used are anacharis, cabomba, and hornwort. These plants don’t put out much of a root system so they take up most of their nutrients directly from the water through their leaves. Because of their relative lack of roots, they are also the easiest to plant. "Planting" for these things is really anchoring them to the bottom of the pond. I just tie a small rock to a bunch and drop it in the pond. You can stick them under a brick or another plant pot. For a good balance in your pond, you need at least 1 bunch of these plants for every 2 square feet of surface area. They’re not expensive and are your best bet against pea soup water, so splurge. They're also one of the favorite foods of your fish, so put them in a container or a fenced off section of your pond using neting. Let the fish eat whatever gets through the container or net. Controlling sunlight is just as easy but takes a few different methods, depending on the season. In the spring, there is not much in the way of higher plant life and the algae will be the first to take advantage of all that spring sun. When it thickens to pea soup, it will also slow down the emergence of your other plants by keeping the sunlight from them. In new ponds and occasionally with established ponds, I will recommend using a vegetable dye in your water. It does the same thing as the tinting on your car windows, except that it is natural and short lived. It will color your water a dark blue-green and will last for about 3 weeks until your other plants are strong enough to do the job. It will also color your rocks a bit, but that color will also go away shortly after your water clears. Your fish won’t notice any difference.

Another way to control algae is to use plants whose leaves float on the water to block sunlight. The most popular of these in your pond are the water lilies. They come in 2 basic forms, tropical and hardy. I’m not going to get into much about specific names since you could be here a week just on the hardy varieties and your ISP would probably like the line back at some time. I'm also going to describe them in pretty general terms because the growers and hybridizers are constantly changing things on us. It’s in picking out your plants that the catalogs come in REAL handy so be sure to visit my Library page and order them. The best pictures are in the Lilyponds and Van Ness catalogs, but the assortment is more varied in some of the others.

Hardys are just that, hardy in most zones in the U.S. and Canada. If you’re a guy, like me, the hardys come in 5 basic colors, white, pink, red, yellow, and changeable, usually from a cream white to a pink, red or "autumn" color (Guys may think of it as orange, but many catalogs call it "autumn" or "sunset".). Hey, most guys only know the colors in the Crayola 16 box. Blooms may start to appear here in north Texas, on the border of zones 7 and 8, from the end of April and quit at frost. (Your conditions may vary... Sorry northern Manitoba) Each flower lasts about 3 days, and will start opening around 8 or 9 in the morning and close each day around 4:00 to 5:00 in the afternoon. The flowers of most hardys sit right on the surface of the water, though a few stand proud by as much as 6 inches. Some may be freely flowering all year and others may have as few as one flower at a time. Most normal sized plants will have 2 to 5 flowers during the peak season in July and early August. The leaves, or pads can be colord from light to dark green with some varieties having mottled leaves. You can get hardy lilies in pygmy, small, medium and large sizes. Except for the pygmy, the size typically refers to the growth spread of the plant, not the size of the blooms, although they frequently go together. The pygmy, though, is tiny in spread and and flowers an pads not much larger than a half dollar. Some of my favorites here are Sumptuosa (red), Colorado "autumn", and Joey Tomocik (yellow). You can usually tell a hardy by its growth in that they grow from a tuber like a Louisiana iris. And some can grow at a "vigorous" rate producing as much as a foot of tuber in a year! Your water lilies will be "planted" from 8 to 16 inches below the water. Hardys need at least 4 hours of direct sunlight to do well, and can survive in full sun all day. All my plants get full sun from sunup to sundown.

The tropicals have many of the same general characteristics as hardys. They also come in a couple of additional colors, blue and purple. Most tropicals have their flowers proud of the water. They also tend to be more strongly scented than the hardys. An additional type of tropical is the night-blooming varieties. These open about 9:00 to 10:00 each night and stay open until about 10:00 the next morning. Night bloomers, so far, come in red, white, and pink. A tropical lily grows from a corm or "bulb" that looks like a pine cone. They can reproduce by producing more corms or viviporously. That is when a new plant starts to grow at the junction of the pad and it’s stem. I have seen one plant with several "babies" still attached and the babies also blooming! The problem with tropicals is that they are not as tolerant of our winter weather, but the larger,showier blooms are worth it. I will get into that a little later on if I have time to do winterizing. If not, we will have to see about a late summer seminar on repotting and winterizing. Tropicals do best with at least 6 hours of full sun and planted 12 to 16 inches under water. In these, I'm pretty partial to Albert Greenberg (the flower, I'm married). A pot of tropical Albert Greenberg next to a pot of a hardy Joey Tomocik is a tough combination tobeat.

A balanced pond will be covered from 50% to 75% with lilies and other floating plants. When we’re talking about lilies, it is best to buy "named" varieties since the growth habits are so varied. If you buy a named variety like Joey Tomocik, you know what you’re getting as far as habit, large flowers standing above the water, versus buying "yellow", which could be anything. You can get some good buys this way if you are willing to take what comesą You can go deeper or shallower with both hardy and tropical lilies, but they will not be as freely blooming deeper, and are susceptible to sun damage shallower.

Bog plants are another category of water plant. These plants live in the shallows of your pond, remember the plant shelves that you didn't put in, and the blocks and boards that you did use? There are dozens of different varieties of these things. They come in both hardy and tropical varieties. I don’t have a lot of pictures of these. Again, this is where your catalogs come in handy in early spring. They're plants that love water, from having their roots under water to having the whole plant as much as 3 inches under water. They also take varying degrees of sunlight from full sun to heavy shade. When you think of bog plants, you think of things you have seen growing beside lakes and streams. Among these are cattails, horsetail, and rushes. Many of your house and garden plants will also grow as bog plants. Many iris varieties will love a wet environment. Umbrella palms, cannas, caladiums, spider lilies, lobelia, some of the palms, all will grow in water, and perhaps better than in your pot in your house or inyour dry garden. A few you might not have heard of are papyrus, taro, arrowhead, lizard tail, sagittaria, pickerel plant, flags, there’s even a water hybiscus. They grow from a foot or so, to some over 8 feet tall. Some have dwarf and miniature varieties. Some flower, some don't. You use your bog plants to frame your pond, bracket different pond features, or serve as a backdrop for your waterlilies. Some bog plants are very unusual. The thalia is a plant with spear head shaped leaves that stand 18 to 24 inches high. Then it sends a flower spike up to 6 feet in the air that has a tassel of small dense purple flowers. What’s really neat is that the flower spike REALLY withstands high winds!!! Some other bog plants have leaves and flowers that sit right on the water. Some of these are mosaic, water poppy, snowflake, and water clover. Again, this is where a good catalog comes in. End of part I.
