Keep the plant in a spot that gets partial sun, which is four to six hours daily. For indoor plants, a window sill is appropriate if the plant is small enough.
Let the soil dry out slightly between watering. When it is dry to the touch, water the plant thoroughly until water comes out of the drainage holes in the bottom of the pot. For outdoor plants, water until the soil is moist 4 to 6 inches below the soil surface.
Keep air circulating around flowering indoor jasmine plants. As the flower plant drops blossoms, rake them up or pick them up by hand and dispose of them to prevent insect infestation or the spread of disease.
Wait until the plant stops flowering to being pruning because the pruning process will encourage the Maid of Orleans to produce more flowers. Use gardening shears to cut off any dead or damaged branches, then cut back any branches that are growing too large for the space allotted for the plant.
