Q: Lotuses are hungry plants and need to be fertilized regularly during the summer months. Apply liquid or tablet aquatic plant fertilizer according to your product's instructions once a month until mid-fall. If you're keeping fish in the pond, remember to use fish-safe fertilizer. Slow-release fertilizer is preferable, as immediate-release products will encourage algae blooms. Provided the water and daytime air temperatures remain above 70F (21C), your lotuses will grow steadily and bloom about 4 weeks after planting. Each flower lasts for 3 days; use a pair of sharp, clean pruning shears to remove spent blooms and yellow leaves down to the nearest growing shoot. Clip spent foliage as soon as you notice it to encourage growth and prevent soiling the water. Never prune foliage below the water's, which could injure your lotuses. the water's temperature, pH, and chemistry. If you're only growing lotuses, the most important factor to monitor is the water's temperature. Once the plants are growing actively, do your best to maintain a temperature between 75 and 85F (24 and 29C). If the water cools below that range, heat it with a submersible pond or aquarium heater. If you're keeping fish in the pond, test the water's pH and ammonia, nitrite, and nitrate levels monthly. Amend the water, if necessary, to keep the pH neutral, ammonia and nitrate levels at 0 ppm, and nitrate levels less than 2 ppm. Find suitable heaters and water amendments online or at a pet store that sells aquatic animals. Oil or detergent-based pesticides can damage lotuses, so avoid these products. For most pests, including spider mites, mosquitoes, and caterpillars, sprinkle a Bt (Bacillus thuringiensis) biological insecticide into the water. After the growing season, cut back plants' spent foliage down to the soil. The tuber, which goes dormant over the winter, needs to be protected from hard frosts. If you've dug an end of the pond deeper than 32in (81cm), move the container to this frost-proof depth until spring. If you didn't build a deep end into the pond, move the container to a cool, dark place, such as a garage. Keep the soil moist so the tubers don't dry out.
A: Fertilize your lotuses once a month during growing season. Prune yellow or brown foliage above the water's surface regularly. Monitor Control pests with an oil-free, biological insecticide. Protect your lotuses from frost during the winter.

Article: The 3 angles inside a triangle will always have a sum of 180 degrees. Name the triangle as an obtuse triangle if any of the angles are greater than 90 degrees. An obtuse triangle will only have 1 obtuse angle. Classify the triangle as a right triangle if the triangle possess a right angle of 90 degrees. A right triangle will only have 1 right angle. Categorize the triangle as acute if all 3 of its angles are less than 90 degrees. Determine that the triangle is equilateral if all 3 of its angles, (which would have to be acute), are congruent. In an equilateral triangle, all 3 of the angles will be 60 degrees, because the sum of the 3 interior angles in a triangle is always 180 degrees.
Question: What is a summary of what this article is about?
Use a protractor to measure each of the 3 interior angles of the given triangle. Record the measurement of each angle in degrees. Distinguish if the angles are right, acute or obtuse according to their measurements. Classify the triangle according to the measurement and the type of angles.

Article: Each section will form a loc. Start separating sections of hair on the back of your head first. Use a comb to separate the hair into a 34 inch (1.9cm) thick section. Use your free hand to hold the section of hair together. If you want fatter locs, you can separate a thicker section of hair. Use sections that are 1 inch by 1 inch (2.5 cm by 2.5 cm) square at the base for medium locs, or double the size for a large loc. Backcombing works best on hair that's 6 inches (15cm) or longer, but can work with hair as short as 3 inches (7.6cm). Backcombing an entire head of hair can take up to 4 hours to complete. Start by combing the section of hair 3 inches (7.6cm) from the roots, towards the direction of the scalp. Comb over the same section 5-10 times until the hair starts to bunch up towards the scalp, then slowly make your way down, towards the ends of the hair. Continue combing in 3 inches (7.6cm) sections until the entire portion of separated hair is backcombed. You can purchase a dread comb online or at a beauty supply store. Grip the hair between your index finger and thumb, a couple of inches (about 5 cm) away from the root. Hold the section of hair tightly and run the crochet needle in between your fingers, through the hair several times. Your hair will bunch up even further. Continue doing this down the length of the hair until the entire section is knotted and looped. After you use the comb and needle, the hair should resemble a dread. Use small rubber bands to secure it at the base of the loc and at the end of the section of hair. This will hold it in place and allow it to keep its form. If you plan to go out in public before you have finished dreadlocking your hair, you may wish to use rubber bands that are the same color as your hair to create a more natural appearance. Look for products like locking gel, lock and twist gel, or beeswax. Dread cream will prevent hair and scalp dryness and will promote the forming of dreads. Squeeze a generous portion into the palm of your hand, then apply it from the root to the end of the loc. Put the loc between the palms of your hands and roll it back and forth several times so that it forms into more of a rounded shape. Start from the root and work your way down to the end of the loc. This will help form the locs and make them look uniform. Continue dreading each section of hair in even sections until the entire head has been dreaded. Do not attempt to backcomb the sections again, or you'll have to restart the knotting process. Remove the rubber bands once you've dreaded all the hair.
Question: What is a summary of what this article is about?
Separate the hair into sections. Comb the section of hair up towards the scalp with a dread comb. Push a crochet needle through the hair to loop it further. Tie rubber bands on the end and root of the loc. Apply dread cream to the loc. Roll the loc in between the palms of your hands. Repeat the process on the rest of the hair.
