Tips on How to Get Jasmine to Bloom Indoors

Jasmine is a classic plant that produces stunning, fragrant blooms. It is a versatile flower that can grow indoors, as well as outdoors, if you live in the right climate that is.

No matter where your jasmine plant is growing, it can be more than a little disheartening when the jasmine doesn’t flower.

Thankfully, you can help encourage your jasmine to bloom indoors with the following tips.

Get the Air Circulating

Proper air circulation is key to not only getting your jasmine to bloom, but to also keep the plant healthy.

Placing the plant near an open window, when weather and temperatures allow it, or turning the fan on low will both help to get the air moving.

Increase the Amount of Light

Jasmines are sun-loving plants that require an abundance of light to get those desirable blooms.

For the best results, make sure your jasmine receives no less than 6 hours of direct sunlight every day.

With that said, the exact amount of sun does vary from one species of jasmine to the next.

So make sure to confirm the lighting requirements for your exact type of jasmine

Keep the Temperature Warm and Mild

Temperatures should fall between 65 and 75 degrees Fahrenheit during the day.

Subjecting jasmine to temperatures below or higher than this range can prevent the plant from blooming. 

While jasmine can tolerate low temperatures, it isn’t the best choice when you want to encourage an abundance of blooms.

Jasmine can grow outdoors in USDA Plant Hardiness Zones 7 to 11, but it is better to move the plant indoors when temperatures start to fall below 40 degrees.

Epsom Salt to the Rescue

Epsom salt is actually magnesium sulfate, which is a beneficial mineral that can help promote seed germination and encourage more blooms to grow.

Which is why this gardening trick is often the go-to method to help get jasmine to produce more blooms.

A good general rule of thumb is to dissolve 2 tablespoons of Epsom salt in 1 gallon of lukewarm water and then water your jasmine once a month with the mixture. 

Add Fertilizer

Adding fertilizer to the jasmine’s soil will help replenish nutrients, while also promoting strong and healthy growth.

The best fertilizer for jasmine is an all-balanced liquid feed with an equal NPK ratio. Apply the fertilizer to the plant after new growth appears, but before you see flower buds emerge.

Repeat the application once every 4 to 6 weeks during the spring and summer, and stop all feeding in the fall and winter.

Thoroughly water the jasmine before applying the fertilizer as fertilizing dry soil can actually burn and damage the plant’s roots.

Prune your Jasmine at the Right Time

It’s best to prune the jasmine immediately after the plant has flowered. This will give the plant enough time to develop proper growth just in time for the next season of blooms.

Pruning the jasmine before it blooms is not recommended since you will more than likely cut off buds, which will prevent the plant from flowering.

Provide a Rest Period for Jasmine’s Blooms

If you want your indoor jasmine to produce blooms in the winter, you will need to ensure the plant has a rest period in the fall.

During the rest period, all light, both natural and artificial, should be avoided during the night. This includes any light from a streetlamp that may shine in through the window.

Temperatures should also be between 40 and 50 degrees Fahrenheit during the rest period, and you should only water the plant about once every 14 or so days during this time.

Once blooms start to appear on the plant, you can move it back to its original location, making sure it receives no less than 6 hours of full sun every day.
