Expert Answer:

Coating a plant, especially the leaves with vaseline will block the stomata. Blocking the stomata would be bad for the plant.  This is because stomata are the pores through which gaseous exchange occurs during photosynthesis.  In addition, transpiration also occurs through stomata. Transpiration pulls more water up through the xylem. So if stomata are blocked, both photosynthesis and transpiration would be affected. This will be harmful for the plant. Such a plant will not remain healthy.
