The video provides helpful tips for restoring a sickly basil plant by pruning, repotting, and providing proper care. The speaker explains the importance of choosing a bigger pot, using a rich multi-purpose compost, and avoiding overwatering. The basil plant needs sunlight and should be checked daily to ensure that the soil doesn't fully dry out. High-nitrogen feed can be given to promote growth, and a grow light may be needed for plants lacking adequate light. Viewers are encouraged to watch a previous video on propagating basil plants.
