Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to take care of plants [title] Give your plants plenty of light. [step] One of the primary concerns for house plants is making sure they get enough light. Keeping your plants on a side-table in your living room may look good, but if it is too far from a window, your plant may not last long.

Ending1: [substeps] Windows should be kept at least 12 feet (3.0 m) above the table. Too low of a window would irritate your plants and cause root rot. Ending2: Look up the sun requirements for your specific plant, and move them to a location that matches those requirements. Keep in mind that windows facing the south side of your house will receive the most light, while windows facing the north side will receive the least amount of light. Ending3: [substeps] Certain types of plants require uv light to thrive. If they are left unattended in a dark environment for too long they will become overactive and die. Ending4: [substeps] When caring for plants above ground, keep them in a criss-cross formation as much as possible. Don't ever put them under an overhead light as a full or partial light source.
