[header] How to treat cold sores in your nose [title] Figure out if you have cold sores in your nose.

Checking the areas in and around your nose can help you figure out if you have cold sores in your nose. <sep> (A) [substeps] Check your nose from the bottom of your nose, just in front of your cheekbone, towards your chin.

(C) [substeps] Use a mirror to check the visible surfaces of your nasal cavity. You may not be able to see much, but even detecting a cold sore can help. (D) [substeps] To figure out if you have cold sores, you may be looking in your nose. Either look back at the corner of your nose, or look to the floor.

question:
[header] How to grow in a greenhouse [title] Choose small, adaptable plants for small greenhouses. [step] Basic, small greenhouses will not be able to support temperamental or larger plants. Pick basic plants that adapt well to a variety of environments for smaller greenhouses, particularly if you haven't grown plants in greenhouses before. <sep> (A) [substeps] Plants that do not retain heat well will be less suitable for smaller greenhouses. Trays and umbrellas are also not good for small greenhouses. (B) [title] Grow plants in smaller, more discreet holes or holes in the ground. [step] Small, hard-to-reach holes or holes are better for larger greenhouses because the roots of plants grow near the leaves. (C) [substeps] The minimum requirements are: no plants raised due to climate extremes (winter greenhouses often use these) and at least 80% humidity (205% during summer and higher during spring). [title] Choose full or partial shade to make the area warmer. (D) [substeps] Herbs, strawberries, tomatoes, cucumbers, and leafy greens all grow well in small greenhouses.
