Why Is Jasmine Not Flowering?

Jasmine will not flower if it has been planted in shade, drought-stressed or heavily pruned the previous year. Too much nitrogen can encourage foliage, which can lead to a loss of flowers. Different Jasmine species can bloom at different times throughout the year. To prevent flower buds from being removed, prune in the Fall.

If your Jasmine has stopped flowering, then continue reading to learn why and how you can encourage blooming …

Different Jasmine Flower Species at Different Times

There are three main Jasmine species that can be cultivated by gardeners. Each species has a tendency to flower at different times throughout the year, which can make it confusing if the Jasmine isn’t blooming when you expect.

  • Common Jasmine (Jasminum officinale) is more sensitive to cold temperatures and flowers in early Spring and can re-bloom in the Summer
  • Winter Jasmine (Jasminum nudiflorum) flowers is more hardy and flowers from November to March.
  • Many Flowered Jasmine (Jasminum polyanthum) more often grown as house plant due to its sensitivity to cold and typically flowers in April/June.

Check the label with the plant to see what Jasmine species it is. This will help you determine when the plant should bloom and if it is suitable for your climate.

The exact timing of flowering is dependent on many factors. Your plant might flower slightly before or after the typical time for your species.

Lacking Sun Prevents Jasmine Flowering

All species of Jasmine require full sun to flower their best and exude their strongest scent. The less sunlight Jasmine gets, the more flowers they will have

Jasmine is native to tropical and sub tropical Asia where it grows naturally in full sun.

Some Jasmine species do not need a tropical climate for growth and flowering (such as Winter Jasmine), but they all require as much sunlight as possible to produce a large display of flowers.

Jasmine flowers in 6 hours direct sunlight, or more during Spring and Summer. The more sun you get the better for blooming and maintaining plant health.

Jasmines that have been exposed to less than 6 hours can experience stress and may not be able to bloom.

If your Jasmine is too shaded, move it to a sunny south-facing wall. Or, if it’s been grown as a houseplant, ensure that it is in the sunniest part of the house. This will encourage flowering.

Jasmine Does Not Bloom Due to Drought Stress

Jasmine likes a balance of consistently moist soil with good drainage so that excess water does not pool around the roots.

If the soil around the roots is dry, it can stop Jasmine flowering. This is especially true if the buds are still developing.

Underwatered Jasmine can have drooping, curling leaves, poor growth, and fewer flowers.

Failure to flower Jasmine because of drought stress can also be caused by underwatering.

  • High winds. Jasmines love light breezes and are used to living in protected areas, such as against walls or fences. Excessive wind can dry out Jasmine leaves and reduce flowering.
  • Poor sandy soils. Jasmine likes moist soil that has lots of organic matter, such as compost, leaf mold and well-rotted manure. Sandy soil can cause rapid drainage that makes it difficult for Jasmine’s roots to get the moisture they need. This will lead to drought and less flowers.
  • Pots that dry out quickly. Jasmine grow very well in pots, however there is an increased risk of drought stress if you are not diligent with watering. The jasmines love full sun and warm places that can dry pots quickly. This is especially true if the pot size is small.

To revive a Jasmine that is not flowering due to drought stress, it is essential to ensure the soil remains moist. These steps will help you improve the Jasmine’s flowering conditions:

  • Increase the watering frequency for your Jasmine to suit the conditions. Because of their deep roots, Jasmines are more likely to need water during drought. However, Jasmines that are less mature and potted Jasmines will require more water in the spring and summer to avoid drought stress. To promote root growth and drought resilience, give your Jasmine a good soak at least once per week during the growing season.
  • Try to find a sheltered location for Jasmine or use other plants to buffer wind to prevent excessive moisture loss from the leaves. To increase humidity and combat the effects of drought, spray the leaves in the short-term with a mistsprayer.
  • If your soil drains quickly then I recommend applying mulch to the soil twice a year. Mulch, such as leaf mold, compost, or well-rotted manure, adds nutrients to the soil and conserves moisture. It also improves the soil’s structure. To conserve moisture during the spring, add a 1″ layer of mulch to the soil. In the fall, add another mulch to protect the roots from frost damage.
  • For potted Jasmine suffering drought stress often benefit if they are transferred to a bigger pot. A larger pot can hold more soil, which means it has a higher capacity to retain moisture. Multipurpose compost, leaf mold, and well-rotted manure are all good options for a potting mix that will help conserve water and encourage flowering.
  • For Indoor potted Jasmine ensure that they are placed in as much sun as possible but keep the pot away from from any sources of heat or air currents form forced air, radiators or air conditioning and water more frequently.

Jasmine will begin to recover from drought stress if it is given more water, kept moistened with mulches and sprayed regularly.

Whether it flowers depends on how stressed it is. For example, drought in Spring can disrupt the flower formation.

A Jasmine that is more hydrated could rebloom later in the year or be in better shape to flower next.

Nutrient Deficient Soil Prevents Jasmine Flowering

If the soil is sandy and low in nutrients then Jasmine leaves tend to turn yellow and display fewer flowers.

Jasmine can also be planted against a wall as a climber.

The foundations of a wall can hinder the natural growth of roots. This is why Jasmine flowers best in nutrient rich soil.

The soil should be amended with compost, leaf mold, and well-rotted manure to ensure the best soil structure, moisture, and nutrients.

However, you can improve the fertility of Jasmine soil by applying mulch.

To add nutrients to the soil and stimulate the soil ecosystem, the best mulch materials are leaf mold, compost and well-rotted manure. This increases the plant’s root availability.

To prevent rot, apply a 12 inch layer of mulch to the soil.

I have already mentioned that Jasmine flowers best when there is no excess nitrogen.

Granular fertilizer can be applied only twice a year to promote flowers and nutrients.

The importance of fertilizer is increased if the soil has sandy conditions and does not retain nutrients.

Jasmine can also stop blooming in containers and pots if there is a deficiency of nutrients.

If Jasmine is in the same pot for a prolonged time, the roots may exhaust the nutrients in the pot.

Repot the Jasmine in larger pots with more soil. The roots will have more nutrients if the pot is larger.

Use a high-quality multipurpose compost mixed with manure and leaf mold to create the ideal soil mixture for Jasmine. This will ensure that it has all the nutrients it needs for flowering.

Jasmine grown in pots will often require more fertilizer. To support blooms, apply a well-balanced liquid fertilizer at half strength once per month from the Spring to mid summer.

Water Stress Prevents Jasmine Flowering

While drought stress can cause flowers to stop blooming, too much moisture around roots can also.

Jasmine requires soil that is both moist and well-draining. It does not like boggy soil around its roots.

Too much water around roots can lead to Jasmines with yellowish leaves and fewer flowers. This is because excess water can cause fungal diseases and deprive roots of oxygen.

Jasmine may not bloom due to water sensitivity.

  • Over watering. It is possible to overwater Jasmine so it does not bloom. If the soil is well-draining and has a good foundation, this is no problem. However, Jasmine will flower less if they are given too much water.
  • Slow draining soils. Root rot can occur when soils are slow or naturally boggy due to clay. This prevents Jasmine from flowering and leads to the plant dying back.
  • Pots and containers. Pots and containers should have drainage holes so that excess water drains easily without roots or compacted soil. Poor drainage can cause water to pool around your Jasmine roots, which can lead to the plant not flowering or even death.

If you suspect that your Jasmine may be suffering from water stress, reduce the amount of watering.

Transfer Jasmine from pots that do not have drainage holes to the right pots. This will allow any excess water to escape.

Jasmine planted in boggy soil should be transplanted. Root rot can kill plants.

Transfer the Jasmine into an area in the garden that has well-prepared garden soil and lots of compost amendments to improve its structure.

If you are unable to change the Jasmine’s location due to its attachment to a fence or wall, then lift the root ball from the ground and plant it in a container.

It is much easier to amend soil with containers or pots so Jasmine can grow and flower, rather than amending soil that is naturally boggy.

Allow the top 2 inches of soil to dry before watering again. This will allow your Jasmine to recover and possibly display flowers.

Too much fertilizer can stop Jasmine Flowering

Jasmine thrives in rich, nutrient-rich soil. It can also flourish in conditions of flowering and growth with a light application of fertilizer.

Jasmine flowers less well when fertilizer is applied too often or in too high a concentration, especially if it contains a lot of Nitrogen.

Nitrogen is necessary for leaf growth, but too much can cause foliage to be stunted.

If your Jasmine has lots of leaves but no flowers, it’s likely that you are feeding it too much.

Reduce fertilizer use and water your Jasmine frequently to remove excess water-soluble nutrients.

If the Jasmine is not producing flowers this season due to excessive fertilizer, it will be difficult to encourage flowering. However, the Jasmine should recover quickly and be able grow new flowers next year.

To avoid the problems caused by too much fertilizer, I recommend slow-release granular fertilizers. They release nutrients at a slower rate than liquid fertilizers and in the right amount to prevent excess Nitrogen.

Miracle-gro is a balanced, all-purpose granular fertilizer that provides all the nutrients Jasmine needs to flower at the correct concentration.


How to Remove Flower Buds

It is important to prune Jasmine at a suitable time of year. You can also cut back the growth from which the flowers are displayed.

Do not prune Jasmine during the Spring and Summer, as this could cause the flowers to stop blooming.

Jasmine is a form of a light prune in Fall after flowering, with the objective to tidy up any unruly growth or untangle any vines.

A hard prune can stop Jasmine from flowering for many years. The Jasmine uses its energy to grow back the leaves before it can bloom.

Jasmines that have been pruned too hard or at the wrong season are more likely to bloom the next year.

Key Takeaways

  • Jasmine’s inability to flower is often due to drought stress, too many nitrogen in the soil, or improper pruning. The growth that Jasmine flowers are made from can be removed by pruning them back in the Summer or Spring.
  • Different species of Jasmine flower at different times of year so check the label to see when your variety should flower.
  • Jasmine requires consistently moist soil during the Spring and Summer, if the soil dries out or is perhaps boggy then the Jasmine can struggle to flower.
  • Too much fertilizer can promote foliage growth at the expense of blooms. Use fertilizer in the spring and summer to plant jasmine in fertile soil.
