In one sentence, describe what the following article is about: If you live in a colder climate but have lilies growing outside in the garden, consider lifting your bulbs over the winter to give them a better chance of survival.  Wait until just after the first frost to lift your lily bulbs. Before you lift them, cut the withered foliage back to about.3 inches (0.8 cm) above ground level. Lifting the bulbs and overwintering them indoors is particularly important for tender varieties of lily, such as tender colored callas. Be sure to dig a much wider hole than to need to avoid damaging the bulb with your spade.  Gently dislodge as much soil as you can from the healthy bulbs without damaging the roots. Rinse the bulbs under cool running water (eg from a garden hose) to remove the rest. It isn’t worth keeping any bulbs that are diseased or damaged. Throw these out with the trash. Avoid composting diseased plant matter as this can spread infection. Make sure the bulbs are well-spaced on the tray to allow air to circulate. A cool dark place such as a garden shed or garage is the most suitable location to dry out the bulbs.  Avoid bringing the bulbs into a heated home to dry them out, as the sudden heat may come as a shock. Additionally, mold may be quick to grow in a warm environment. A temperature of 60–70 °F (16–21 °C) is ideal. The bulbs should not be exposed to sunlight. After the bulbs have dried out for a few days, dust them with a fungicidal powder. Put them into paper bags with a small amount of dry peat moss or vermiculite.  You could also use a cardboard box, provided you make some ventilation holes to let air circulate. Avoid letting the bulbs touch each other — you can put moss or vermiculite between them to prevent this. The idea is to prevent one bulb from infecting another if it develops mold. Damp and rot are the biggest threats to overwintering bulbs, so protect them by storing them in a dark, dry place. However, you should not allow the bulbs to dry out completely.  If the bulbs appear dry or shrunken, mist them lightly with water to prevent them from drying out too much. Bulbs need to rest for a few months before growing again. Therefore, it’s best to replant them outdoors in mid or late spring, once the threat of frost has passed and the the ground is warmer. Your lilies are more at risk of rotting due to the winter rain than being damaged by the frost, so avoid replanting if the ground is waterlogged (even if the weather is mild.)
Summary: Lift your lily bulbs after the first frost. Carefully dig out your bulbs. Check your bulbs carefully for rot or any signs of disease. Put the bulbs on a tray and allow them to dry for a few days. Dust the bulbs with fungicidal powder and put them in storage. Store the bulbs in a dark, dry place. Re-plant the bulbs outdoors in mid to late spring.

Problem: Article: Class is a time to learn new things and solidify the information that you may have learned in the previous class. If you don’t go to class, it is much more difficult to stay current with the material.  Ask questions in class. Your teacher is there to make sure you have a solid grasp on the material. If you have a question, don’t hesitate to ask it. Some of the other students in the class likely have the same question. Prepare for class by reading the lesson you are going to cover ahead of time and know the formulas, theorems, and postulates by heart. Pay attention to your teacher while you are in class. You can talk to your classmates at break or after school. Geometry is the math of shapes and angles. To understand geometry, it is easier to visualize the problem and then draw a diagram. If you're asked about some angles, draw them. Relationships like vertical angles are much easier to see in a diagram; if one isn't provided, draw it yourself.  Understanding the properties of shapes and visualizing them is essential to succeeding in geometry. Practice recognizing shapes in various orientations and based on their geometric properties (the measure of angles, number of parallel and perpendicular lines, etc.). Study groups are a good way to learn the material and clarify concepts you don’t understand. Having a group that meets on a regular schedule will also force you to stay on top of the material and try your best to comprehend it. Studying with classmates is useful when you come to more difficult topics. You can work through them together to figure them out. One of your study mates may understand something that you don’t and help you out with it. You might also be able to help them understand something and learn it better by teaching them. A protractor is a semicircle-shaped tool used to measure the degree of an angle. It can also be used to draw angles. Knowing how to properly use a protractor is an essential skill in geometry. To measure the degree of an angle:  Align the center hole of the protractor over the vertex (center point) of the angle. Rotate the protractor until the baseline is on top of one leg of the angle. Extend the angle up to the arc of the protractor and record the degree it falls upon. This is the measurement of the angle. Homework is assigned because it helps you learn all of the concepts in the material. Doing the homework teaches you what you really understand and what topics you might need to put more time into. If you come across a topic in your homework that you are struggling with, focus on that topic until you understand it. Ask you classmates or your teacher to help you out. When you have a firm understanding of a topic or concept, you should be able to teach it to someone else. If you can’t explain it to them so that they also understand, you likely don’t get it as well as you thought either. Teaching material to others is also a good way to enhance your own memory or recall of the topic.  Try teaching your sibling or parent some geometry. Take the lead in a study group to explain something you know really well. Geometry is as much a skill as a branch of knowledge. Simply studying the rules of geometry will not be enough to get an A, you need to practice solving problems. This means doing your homework and working extra problems for any trouble areas.  Make sure to do as many practice problems as you can from other sources. Similar problems may be worded in a different way that might make more sense to you. The more problems you solve, the easier it will be to solve them in the future. Sometimes going to class and talking to your teacher just isn’t enough. You might need to find a tutor who has more time to focus specifically on what you are struggling with. Working with someone one-on-one can be very useful in understanding difficult material.  Ask your teacher if there are tutors available through the school. Attend any extra tutoring sessions held by your teacher and ask your questions.
Summary:
Attend every class. Draw diagrams. Form a study group. Know how to use a protractor. Do all of the assigned homework. Teach the material. Do lots of practice problems. Seek extra help.
