INPUT ARTICLE: Article: Besides being rich in protein and vitamin D (both are key to strong hair), salmon contains omega-3 fatty acids, which are essential for healthy hair. About 3% of the hair shaft is made up of omega-3 fatty acids, which are also found in cell membranes in the skin of the scalp, and in the natural oils that keep the scalp and hair hydrated. If salmon doesn't thrill you, you can also get essential fatty acids from fish like herring, sardines, trout, and mackerel, as well as avocado and pumpkin seeds. Walnuts are the only type of nut that have a significant amount of omega-3 fatty acids. They're also rich in biotin and vitamin E, which helps protect cells from DNA damage. Walnuts also have copper, a mineral that helps keep your natural hair color rich and lustrous. Try using walnut oil in your salad dressing or stir-fry instead of canola or safflower oil. Oysters are rich in zinc, a lack of which can lead to hair loss (even eyelashes), as well as a dry, flaky scalp. Just three ounces of oysters contain almost five times your daily zinc requirement. They also boast a high level of protein. Zinc can also be found in  nuts, beef, eggs and fortified cereals and whole grain breads. Sweet potatoes are a great source of the antioxidant beta carotene, which your body turns into vitamin A. Vitamin A helps produce and protect the oils that nourish the scalp. A lack of vitamin A can lead to a dry, itchy scalp and problems with dandruff. Carrots, cantaloupe, mangoes, pumpkin, and apricots are all good sources of beta carotene. A great source of protein, eggs are loaded with four key minerals: zinc, selenium, sulfur, and iron. Iron is especially important, because it helps cells carry oxygen to the hair follicles, and too little iron can lead to anemia, which is a major cause of hair loss, particularly in women.  In addition to other nutrients, eggs are a natural source of the b-vitamin biotin, which supports healthy hair.  You can also boost your iron stores by eating animal products, including chicken, fish, pork, and beef. Spinach is a super-food containing iron, beta carotene, folate, and vitamin C which combine to help keep hair follicles healthy and scalp oils circulating. If you're not a spinach fan, try eating similarly nutrient-rich dark, leafy vegetables such as broccoli, kale, and Swiss chard. Tiny but mighty, these legumes are teeming with protein, iron, zinc, and biotin, making them a great staple for vegetarians, vegans, and meat eaters alike. Greek yogurt is high in hair-friendly protein, vitamin B5 (pantothenic acid -- an ingredient you'll often see on hair care product labels), and vitamin D, which emerging research links with hair follicle health. Other similarly beneficial dairy products include cottage cheese, low-fat cheese, and skim milk. Blueberries are a super fruit with numerous health benefits, but it's their high vitamin C content which really helps keep hair in top shape. Vitamin C is critical for boosting circulation to the scalp, supporting the tiny blood vessels that feed the hair follicles. Too little vitamin C in your diet can lead to hair breakage. Nothing beats poultry for providing protein, along with hair-healthy zinc, iron, and B vitamins to keep strands strong and plentiful. Because hair is nearly all protein, foods rich in protein are literally the building blocks for great hair. Lean cuts of beef are another good source of protein. Although maintaining a healthy diet is an excellent way to get the vitamins necessary for healthy hair, taking a vitamin supplement can make it easier to ensure that you are getting all of your daily requirements. The top 5 vitamin supplements you should take for healthy hair are biotin, vitamin A, vitamin E, vitamin B5 and Inositol. Remember to check with your health care professional before adding any supplements to your diet.

SUMMARY: Eat salmon. Eat walnuts. Eat oysters. Eat sweet potatoes. Eat eggs. Eat spinach. Eat lentils. Eat Greek yogurt. Eat blueberries. Eat poultry. Take a supplement.

INPUT ARTICLE: Article: Once established, the tree can withstand short periods of drought, but it always prefers to be kept moist. When it is still young, within the first one or two seasons after being planted, you should give the tree a thorough watering if you experience a drought that lasts for two weeks or more. You can prune during the late fall or on a mildly cold day in winter, while temperatures are above the freezing point. You can also prune during the late spring, after the blooms have fallen from the tree. Remove diseased wood first. Then, cut away old lower branches close to the trunk, as well as any branches that are intertwined or growing in the wrong direction. Never remove more than 1/4 of the tree at once. Ideally, you should test the soil each fall to determine if it's missing any vital nutrients. Instead of picking a general all-purpose fertilizer, add amendments that will introduce the lacking nutrients back into the soil.  Many redbud trees grow well enough on their own without the use of fertilizer, but this may not be true in all cases, so it's important to check the soil on a yearly basis. Typically, you won't need to add much if any nitrogen to the soil. You may need to select a slow-release fertilizer with higher concentrations of phosphorus and potassium than of nitrogen, and only apply it once, toward the beginning of the autumn. Leaf anthracnose, botryosphaeria canker, and verticillium wilt are the three diseases that affect redbud trees most often. Wood-boring bugs have been known to attack the soft wood of these trees, and insects like the redbud leaffolder, grape leaffolder, and Japanese weevil are known to eat the leaves. A healthy tree is less likely to succumb to these threats than a damaged tree, so prevention is the best remedy. An infected tree should first be made healthy before you consider applying an appropriate pesticide or fungicide.

SUMMARY:
Make sure the tree receives moderate amounts of water. Keep the branches pruned. Fertilize only as needed. Watch out for pests and disease.
