Q: If your soil pH tested below 7, add a cup of dolomite or quick lime to the soil. Mix well, then retest with your probe. Use this method to slowly change the pH of your soil. Wood ash in moderation helps as well. Both are available at local gardening centers. Follow the advice in your commercial test probe kit to determine how much of these substances you will need to add to achieve the desired pH. If you need to change your soil pH level more than one full point, contact a local gardening professional. They can help you calibrate your soil so it can be amended most successfully. If your soil pH tested above 7, add a cup of organic matter, such as pine needles, peat moss, or decomposed tree leaves. Then, retest the soil to gauge the new pH. Add additional cups, testing as necessary, until you reach the desired level. Sulfur is very effective as well. Use the instructions in your commercial test probe kit to determine how much of these additives you will need to add to achieve your desired pH. If your soil needs to be adjusted more than a full pH point, contact a local gardening or landscaping professional. They can help you calibrate your soil to the right level through an on-site evaluation. For example, add sulfur to a certain area of your garden to encourage beautiful blue blooms on your hydrangeas, which prefer more acidic soils. The pH of your soil does not need to be uniform your entire garden over; feel free to alter it to support different plants. You can consult the Old Farmer's Almanac to determine the best pH for your particular garden. Some plants prefer a pH of 7 while some fruits favor a lower pH.
A: Make your soil less acidic. Make your soil less alkaline. Change your soil pH to suit specific plants.

Article: Found across most of the world, Argentine ants are dull brown and are all about ⅛" (3 mm) long, with a pointed node. They move rapidly in tight trails, prefer sugar but will eat protein and fat, and have a musty odor when crushed. Colonies are typically in damp areas outdoors, but are also found indoors. Eradication is extremely difficult due to multiple cooperating colonies and multiple queens per colony. These ants are black, dark brown, or dark red, or a combination of these. They vary in size from ¼" to ½" (6 to 12 mm), and have one erect node and no thorax spines. They move in loose trails and are often found near wood, along with a strong odor and piles of sawdust, soil, and insect parts. Look for trails across lawns where vegetation has been thinned or removed. Crazy ants are named after their rapid changes of direction, and perhaps for their odd-looking, extra-long antenna and legs. Their slender, dark grey, black, or brown bodies are 1/16 to 1/8" (2–3.5 mm) long, have a flat node that's difficult to see, and have no spines. In the tropics, some crazy ant species are yellowish-brown instead and can be up to 1/5" (5 mm) long, with a darker gaster (rear abdomen). These one-node species are common pests in some areas, but much more limited in global distribution than the species above:  Ghost ants: Very small (1/16" or 2 mm), with a black/brown head and pale abdomen. Flat, hidden node, no spines. Usually outdoors in tropics, or on plants from greenhouses or tropics.  Odorous house ants: 1/8" (3.5 mm) long, one flat, hidden node, no spines. Strong, unusual odor when crushed. Primarily found in trails looking for sugar, but this varies.  Rover ants: male workers are 1/16" (2 mm), small and black with unusual straight antenna. Most easily distinguished by the much larger, winged females, which are found near light or floating in standing water.  White-footed ants: These 1/8" (3.5 mm) ants are usually black with pale "feet." A flat, hidden node, no thorax spines.

Problem: Article: Move plants and items to different areas of the tank. This will create a whole new playground for your goldfish to play and explore. New items, such as new plants or items at the bottom of the tank, will give the fish new things to explore and interact with. Remember to only add items that are safe for the tank though, so go to your aquarium store and buy something new. Playing with your goldfish while you feed it is a good opportunity to train it and give it mental stimulation. In fact, goldfish can even be trained to ring a bell for food.  This provides stimulation and fun for the goldfish. Interacting with your goldfish is especially important if it is the only fish in your tank. The interaction will give it stimulation that it’s not getting from other fish. In order to keep your goldfish happy and healthy, you should strive to not scare or disturb it as much as possible. Doing things like tapping on the glass or putting your hand in the tank unnecessarily scares your goldfish, which puts stress on its health. Fish that are scared will go to hiding places in their tank. If you want to see your beautiful fish swimming around, don't scare them into hiding.
Summary: Rearrange the tank during your monthly cleaning. Add new items to the tank. Interact with your goldfish while feeding it. Never purposely scare your goldfish.

Q: The diced onion will be translucent when it's cooked. Crumble the 1 pound (0.45 kg) of beef with a spatula as it cooks and stir it frequently so it cooks evenly through.  Using lean ground beef will cut down on the amount of fat and grease if you want a healthier dish. Always wash your hands with soap and warm water when you've handled raw meat. Otherwise, you could contaminate the rest of the kitchen. Pour them carefully into the bowl of the slow cooker so hot juice or grease doesn't splash onto you. Or use a slotted spoon to scoop out the mixture if you don't want the fat from the oil in the dish. Line the slow cooker with a slow cooker liner or spray the bowl of the slow cooker with cooking spray before adding the ingredients. Both of these will make cleanup easier. Stir the 1 cup (240 ml) of water, 2 cups (470 ml) of milk, and all of the spices in with the beef and onions. Mix until everything is combined in the slow cooker. You can use any type of milk, whether it's 1%, 2%, or even a non-dairy alternative like almond milk or soy milk. The best thing about a slow cooker is you can just set it and forget. Check it occasionally to make sure everything is cooking evenly and give it a gentle stir.  The bottom and sides of the slow cooker are the hottest. By stirring it every so often, you'll prevent some spots from being overcooked while others are undercooked. Depending on the strength of your slow cooker, you may need to adjust the cooking times. Make sure the lid is on tightly so the liquid doesn't evaporate. If you add the pasta too early, it will get mushy. Mix in 3⁄4 cup (180 ml) of macaroni noodles at the end so it has enough time to cook properly.  For al dente pasta, add it closer to 10 minutes before serving. Other pasta options will work, too. Choose the style and shape that you like best. The heat of the slow cooker and the Hamburger Helper will melt the cheddar cheese as you mix it in. Either freshly grated or pre-grated cheese will work, although freshly grated will be creamier.  You can also cover the slow cooker for 2 minutes after adding the cheese to let it melt completely. If it's too hot, let it cool for 5 to 10 minutes before serving it.
A:
Cook the onion and ground beef in a skillet until the meat is brown. Transfer the onions and ground beef into a slow cooker. Add the rest of the ingredients, except the pasta and cheese. Cover and cook for 5 to 8 hours on low or 3 to 4 hours on high. Add the pasta 15 minutes before serving and let it keep cooking. Stir the 1 1⁄2 cups (350 ml) of cheese in when you're ready to eat.
