article: Plants are susceptible to viruses, bacteria, and fungi just like humans are. You can prevent the spread of disease by working with sterilized gardening tools, especially when you're carrying out a delicate procedure like a graft. Not only will this help ensure the graft takes, but also that the plant survives.  The easiest way to sterilize your budding knife is with ethanol or isopropyl alcohol. Get a clean rag or cloth damp with the alcohol. Wipe the blade thoroughly, making sure you get the tip, sides, and base of the knife. Be careful not to cut yourself in the process. Set the blade aside to air dry for a few minutes. With clean pruning shears, prune your rootstock plant to remove dead foliage, blooms, and stems. Select a healthy stem with many well-developed leaves for the actual graft site. Use the budding knife to remove all the buds and prickles from the middle section of the stem.  Removing the prickles isn't strictly necessary, but it will prevent you from cutting yourself during the graft. Removing the buds is important because you want the buds from the scion to grow, not the ones from the rootstock. When pruning or taking cuttings, cut on a 45-degree angle to reduce damage and increase circulation. With the bud knife, cut an inch-long T shape into the bark of the rootstock. Make sure you do not penetrate the cambium layer, which is a wet, pale green color. Use the tip of the knife to gently open the flaps you created in the bark. The best place for the T cut is near the middle of the stem, between two nodes. Nodes are where leaves and buds grow out from the stem. Cut off the stem you want to use for the scion. Cut off the top and bottom from the stem, leaving a 2-inch (5-cm) section in the middle. Make sure that section of stem has at least one bud eye, where a new leaf could grow from the stem.  Use the budding knife to cut off any prickles, buds, and leaves from the piece. Trim the stem an inch (2.5 cm) below the lowest bud eye. Place the knife on the stem above the bud eye. Insert the blade deep enough into the stem to penetrate the bark and the cambium layer. This is the layer just behind the bark that carries nutrients. Cut out the bud eye, making sure you take the bark and cambium layer as well. Make sure the bud eye is facing upward, as this means the stem is facing the right direction. As you insert the scion into the rootstock, the bark flaps will open around the scion. Push the scion all the way in to the bottom of the T, leaving the bud eye exposed at the top of the flaps. The cambium layers of the scion and root stock will now be in contact, and this is what will allow the graft to take. Close the bark flaps over the scion. Wrap a few layers of grafting tape around the graft. Wrap the area above and below the bud eye, but leave the bud eye itself exposed. Don’t be afraid to pull the tape gently to stretch it out, as this will ensure the cambium layers stay in contact.

All social media networks have privacy controls. When you adjust these settings, you have control over who has access to your information (e.g. profile, pictures, posts, data). Sites regularly change their privacy policies so stay up-to-date.  Facebook allows your friends to share information about you. Be sure to go into your privacy settings and set limits. The default for privacy settings is completely open and accessible profiles. Only be friends with people that you actually know. Reject any requests from complete strangers. You should also go through your friend list every few months to see who you are sharing your information with. The more friends you have, the more people will know about you and what you are doing. Remember that anything that you post is public information and is permanent. Even if you delete a post or a picture, they can still be found. If you do not want the information revealed on a billboard, it is best not to post.  Remember that employers often check social media during the hiring process. Never share personal details or your current location. Use different usernames and logins for each of your accounts. This way it will be harder to track your online activity. You can also use an avatar or some other picture instead of using your actual picture for an online profile. You can also block your IP address so that you cannot be tracked when you are using the internet.
