How Compost is Made

Where I live in Portland, Oregon, the compost and recycling bins are picked up every week, but the trash bin only every second week. When the program first started (cutting back from weekly trash pickups), I was worried—how would composting suddenly reduce my trash output so much?

Well, it worked (mostly), and these days it's rare that I even fill the trash bin every two weeks. It turns out that a huge chunk of the trash I was creating is compostable, a lot is recyclable, and it has been an easy transition. But how does compost get made from the stuff I chuck into the green bin? In this video from KQED Science, we see how San Francisco creates their compost, and gives us an idea of why compost is so useful to plants. Have a look:

For a look at a different compost plant, here's a How It's Made segment on compost:

And if you want to make compost at home, there are a zillion videos explaining how.

Why Scientists Are Hunting Down Iguanas in Florida

In South Florida, iguanas had better watch their backs. That's because scientists are on an unusual hunt to kill them, with the help of captive bolt guns and a $63,000 research grant, according to the Sun Sentinel.

It's not as cruel as it might seem at first glance. The green iguana, native to Central and South America, is an invasive species in Florida. The large lizards—which can grow up to 6 feet long—first made it to Florida in the 1960s, and as their population has exploded, they have expanded farther north. The reptiles damage roads, sidewalks, sea walls, and flood-control canals with their burrows; chomp their way through landscaping; spread Salmonella, largely by pooping in people's backyard pools; and compete with the endangered Miami blue butterfly for precious food resources.

The population boom has caused an uptick in complaints from residents, Florida Fish and Wildlife's Sarah Funck told the Sun Sentinel in 2017, pushing the state to find new strategies to deal with the reptiles. One approach? Hire scientists to hunt them down and kill them.

As part of the Florida Fish and Wildlife research project, 15 University of Florida biologists have been tasked with executing as many iguanas as possible in Broward County (home to Fort Lauderdale and parts of the Miami metropolitan area), setting out in teams of two at night. Armed with flashlights and captive bolt guns—which are often used on animals in slaughterhouses and are considered a humane way of killing an animal instantly and painlessly—the researchers attempt to sneak up on sleeping lizards and shoot them before they can scurry away. They also sometimes dispatch the iguanas by smashing their heads against a hard surface, including the side of a truck or a boat.

They've exterminated 249 lizards so far. They take the dead animals back to the lab to be weighed and measured for their dataset, then deposit the carcasses in a landfill. The iguana killing spree is expected to last into May.

While they have tried trapping the iguanas in county parks, they haven't succeeded in capturing any with that method.

As part of the Fish and Wildlife Conservation Commission's iguana-eradicating efforts, the agency has also been hosting public workshops on how to deter and trap iguanas and has hired a dedicated trapper to control populations on public lands in the Florida Keys.

5 Trouble-Shooting Tips to Keep Your House Plant Alive

Maybe you’ve heard that houseplants can help improve indoor air quality. Perhaps you’ve read that looking at plants can help you focus. Or maybe you just really like how that ficus looks in your living room. But buying a plant and keeping it alive are two different things, and the answer to your botanical woes isn’t always “don't forget to water it.”

Here are five green-thumb tips to make sure your plant stays as leafy green as it was the day you bought it.

1. DON’T OVER-WATER.

You don’t want to neglect your plant, but it’s easy to go overboard with the watering can, and that can be just as harmful as forgetting to water your plant for weeks. A watering schedule can help you keep track of whether or not your plants need attention, but you shouldn’t water just because it’s Sunday and that’s when you usually do it. Before you go to water your plant baby, make sure it actually needs it.

Your plant’s water needs will vary based on the type of plant, its location, how old it is, and plenty of other factors, but there are a few rules of thumb that can put you on the right track. Lift the pot. If it’s heavy, that means that the soil is full of water. If it’s light, it’s dry. Dig a finger into the soil around its roots, making sure to feel beneath the surface. Still damp? Hold off. Dry? Grab the H2O.

If you really struggle to strike the right balance between too much and too little water, consider a smart plant system. And regardless of how often you water, make sure to use a pot with good drainage to prevent root rot.

2. WATCH THE TEMPERATURE.

Be aware of where your plant is situated in the room, and whether there might be any temperature extremes there. Is your fern sitting right above the radiator? Is your peony subject to a cold draft? Is your rosemary plant stuck leaning against a window during a snowstorm?

As a rule, most houseplants can handle temperatures between 58°F and 86°F, according to a bulletin from the University of Georgia. The ideal range is between 70°F and 80°F during the day, and between 65°F and 70°F at night. Below 50°F, sensitive plants can suffer damage to their leaves. However, as with most plant advice, it depends on the species—tropical plants usually do well in higher temperatures, and some other plants are happier in colder rooms.

If your sad-looking plant is sitting in the middle of a cold draft or right next to the heater, consider moving it to a different spot, or at least a few inches away. If it’s near the window, you can also draft-proof the window.

3. MAINTAIN HUMIDITY.

Be mindful of the kind of ecosystem that your plant comes from, and know that keeping it happy means more than just finding the right amount of sun. A tropical plant like an orchid won’t thrive in dry desert air. According to the Biology Department at Kenyon College in Ohio, a dried-out plant will look faded and wilting. You can immerse it in water to help it bounce back quickly. (Warning, though: A plant that’s getting too much moisture can look that way, too.)

If your home gets dry—say, when you have the heater on full blast in the winter or the AC on constantly during the summer—you’ll need to find a way to keep your plant refreshed. Your can buy a humidifier, or create a humidity tray by placing the pot on a tray of pebbles soaked in water. The plant will soak up the humidity as the water under the pebbles evaporates. You can also get a spray bottle and mist your tropical plants periodically with water. (But don't mist your fuzzy-leafed plants.)

Not sure how humid your house is? You can get a humidity gauge (known as a hydrometer) for less than $10 on Amazon.

4. LOOK OUT FOR BUGS.

Even if you do all of the above correctly, you can still struggle to keep a plant healthy due to infestations. Keep an eye out for common pests like spider mites, which will leave brown or yellow spots on leaves or make the plant’s color dull. If you discover these tiny mites (you may need to use a magnifying glass), wash your plant immediately with water to knock off as many mites as possible. Wash the plant with an insecticidal soap, too, but make sure the label says it’s effective for mites.

5. DON’T DISCOUNT THE POT.

Healthy plants often outgrow their homes. if you notice that there are roots coming out the drainage holes at the bottom of your pot, or that water sits on the surface of the soil for a long time before draining down, or that your plant’s roots are coming up out of the soil, it’s time to upgrade to a bigger pot. Signs of a “root bound” plant whose root system is too big for its container can also include wilting, yellowed leaves, and stunted plant growth.

No matter what the size of your plant, it’s good to repot it once in a while, since the nutrients in the soil deplete over time. Repotting creates a fresh nutritional start and can help perk up unhappy plants.

If your plant looks unhealthy and you're still stumped, try consulting the website of a university horticulture department for other signs of plant distress and potential solutions.
