How Increase Lavender Blooms Properly

To increase the number of lavender blooms, plant it in full sun, on sandy soil. Prune in spring to encourage the growth and support for more blooms.

The excessive watering of lavender and adding fertilizer may stress the plant, which results in less blooms.

Deadhead any flowers that are brown to direct the plant’s energy towards producing more flowers, not seeds. A stone mulch that is white creates a reflective surface to enhance the brightness of your lavender , resulting in a greater number of blooms.

Read on for the 7 suggestions and learn how to increase the quantity of flowers of lavender and also the intensity of the scent emanating from the foliage…

The most important factor is the full sun. Factor to Increase Blooms

The main aspect that determines the quality of lavender flowers in the summer is the amount of sun the lavender gets.

Lavenders can be adaptable to full sun in dry climates, and are found in areas like Spain, Italy and Portugal in coastal regions with a breeze. They provide the highest yields in terms of flowers, oils and their strong scent when you have a all-day sun throughout the summer long.

The less sunlight the lavender gets, the less blooms will be visible and the less attractive growth, leggy and more prone to diseases.

If you can, move your plant to the most sunny spot within your yard (at minimum six hours of sunshine) in an area that has adequate airflow, which can help lower the chance of fungal diseases and ensures that the plant is healthy.

You might want to consider moving your lavenders into containers or pots to allow you to move them to the sun in case you are limited to plant them within your garden boards.

Commercial lavender growers have their most productive years in terms of flower oil production, scent and the fragrance of the leaves on seasons with the driest and most sunny summers.

Prune in the Spring to Stimulate Blooms

The lavender plant can be pruned either in the Fall or Spring according to the preference. But, I have talked to commercial lavender growers from Washington USA that insist pruning in spring is the best to increase the bloom of lavender.

This is due to the fact that lavenders only bloom on new season growth.

When gardeners trim lavender, it stimulates new growth , which results in a larger amount of foliage and stems. The flowers of this season will be seen on the new growth , and with more stems, there will be more opportunities to bloom.

Cut lavender back in April or March and the new stems will sprout abundantly in time for blooming.

The older lavender plant is not productive (particularly the base that is woody) that is just one of the main reasons why it is important to trim it annually.

Low to Medium Fertility Soil / Do not use fertilizers to increase blooms.

Lavenders thrive in neglect, with minimal demands on watering and prefer soils with low to moderate fertility.

This is because of the adaptations of lavenders to the harsh climate of their home Mediterranean region, which has very little rain and sandy soils that are deficient in nutrients.

The lavender thrives in these conditions and produces the highest number of blooms and most powerful scents when gardeners recreate a few of their natural habitats.

Don’t add fertiliser or grow lavender plants in a rich soil, as this can encourage unruly growth of the foliage and will harm the flowers.

Instead, you should attempt to recreate the soil they prefer through amending your soil with an adequate amount of sand or grit in order to guarantee good blooms.

If you are planting or transplanting to another area, mix about 1/3 of sand or grit to two thirds of compost or potting soil since this is similar to the soil conditions that allow lavender to thrive.

Sand and grit aid in helping regulate the level of compost’s nutrients to ensure that the soils have low to moderately fertile and provide the ideal conditions for lavenders to blossom.

Sand can also improve drainage in the soil, which is essential to ensure the soil has adequate moisture, so that the lavender’s roots are in good health (lavenders like dry, sandy soil, between watering sessions).

(To know more about this, read my blog post on best mixture of soil for the lavender).

Use a White Mulch

This is among the most unconventional ideas I’ve gathered throughout the years, which I received from an experienced commercial farmer in California.

Lavender blooms best in the summer when it is particularly sunny.

Sunlight is an important element in promoting blooms that a white, reflective mulch like lime stone, or any decorative white gravel could help reflect the sun’s rays back on towards the plant , increasing the brightness of the area, which can increase the amount of blooms you can get for your lavenders.

The growers I’ve spoken to about this to say that it is the most effective way to boost blooms, and that the scent of the leaves is particularly powerful.

The mulch can also assist in keeping weeds away and the increased brightness will cause evaporation of the leaves, which is helpful in reducing the chance of fungal infections.

Water Infrequently

One of the most important elements that determine the quantity of lavender blooms can be the amount of time spent watering.

Lavenders are drought-resistant plants due to the fact that they have Southern Europe origins and actually prefer dry climates.

Too often, water lavenders will cause harm to the lavender and as a sign of stress, the lavender may droop or fade in appearance. It will also result in fewer blooms during the summer.

The lavender plants that are established (that have been in cultivation for longer than three months) typically don’t require any irrigation at all. They will get all the water they need from rain, even when it is not frequent.

Do not water lavenders if there isn’t any rain and intense sunshine for at least two weeks. Potted lavenders may require additional irrigation and to prevent problems it is essential to select the correct pot to grow lavenders in..

The newly planted lavenders, however, need more regular watering since their roots attempt to adapt and establish themselves in their new environment. (Learn more about the watering requirements for freshly planted lavenders).

Keep in mind that lavenders prefer drought-like conditions, so gardeners can create more issues due to excessive watering than when they are under-watering.

Reduce the frequency of watering so that your lavender will remain healthy and beautiful, and will create a stunning flower.

Deadhead the Blooms Regularly

Deadhead the the blooms of lavender as often as you can to encourage blooms.

Deadheading as an method to increase blooms is particularly effective in the case of French, Spanish and Portuguese lavenders, which be more prolific in their blooming time than the English lavenders (although they’re not as robust or like the English lavenders, such as the lavender called Hidcote).

When the flowers begin to brown, cut the petals off. This can stimulate the plant to create more flowers, rather than directing the energy to produce seeds.

The lavender plants seeds within the brown flower heads therefore you can remove the flowers in case you want to harvest seeds. But growing lavenders from seeds is more difficult and precise than propagating the lavender by cuttings.

When you regularly deadhead your lavender, it will appear healthy and blooms will increase substantially, especially for the species of lavender which flower for the longest time (French and Spanish lavenders can begin flowering in the spring/summer months and go through until the fall The hotter and sunnier your area, the longer the blooming time for most lavenders).

Key Takeaways

  • In full sun, lavender produces the largest blooms and most intense scents.
  • Pruning lavenders in spring can stimulate growth, which will help the flowering.
  • Plant lavender in soils that are low to moderate in fertility through amending soil using the sand of horticulture or grit. Lavender flourishes and displays more flowers when planted in soils that are sandy.
  • Do not apply fertilizers as they can encourage growth of foliage and reduce blooms.
  • It is recommended to water lavender only occasionally. They are drought-resistant plants that thrive in dry conditions . Watering often can cause stress, which could reduce the amount of flowers. Lavenders thrive in neglectful sandy soils.
  • Utilize a white mulch like grit or stone to reflect more light on the lavender. This will boost the number of that the lavender flowers.
  • Deadheading the flowers frequently will make sure that lavender shows more flowers.
