How Much Space do Lavenders Need to Grow Well?

Last Updated on November 5, 2022 by Stephanie

Place lavenders at least 2 feet from each other and other plants. A distance of 2-3 feet is essential to ensure that lavenders dont have to compete with space, water and nutrients, or even sunlight. The amount of sunlight will affect the intensity of scent and the amount of oil produced, and the number of flowers that are displayed.

One important thing to keep in mind are the different dimensions of the lavender varieties at full maturity, which will determine the distance they must be planted. Continue reading for an easy table of the distance to plant different sizes of varieties of lavender…

Why Lavenders require 3 feet of space

Lavenders should be planted at minimum 2 feet from one another or any other plant to show the most beautiful flowers, to produce more oil, and remain healthy.

Lavenders can thrive when they are placed closer together, however youll be affecting the quality of the plant in regards to:

  • Sunlight. Lavenders like full-sun (at minimum six hours). The more sunlight they get, the more they flower and produce oils. When you place lavenders close to than 2 feet from each other or in close proximity to other plants, they will create shade over one another (particularly those with larger sizes that can grow up to 40 inches tall) Sunlight is among the most crucial conditions for growth for lavender, so it is essential to plant them in a space that allows them to get enough sunlight.
  • Space for each of the lavenders roots system when it is mature. The roots of lavenders have the average of approximately 10-inches or more, with some varieties like Hidcote Giant which require a minimum of 3 feet of space in order to grow properly. A space of 2-3 feet will stop each plant from being in competition for water and nutrients, and will allow lavenders to grow their roots to improve stability, allowing them to develop and blossom to their fullest potential.
  • Air flow. Another crucial factor in determining the location of lavenders is the flow of air around the plant. If youre planting lavender in a humid, temperate humid, moist or humid climate , then the space each plant gets is even more crucial. The lavenders are adapted to the dry environment that is typical of the Mediterranean therefore placing them in a part of your garden that has some breezes can aid in reducing the effects of humidity. Lavender thrive naturally in fast draining sandy soils. They are drought-tolerant plants that thrive in dry conditions. When theyre exposed to excessive humidity, they can develop fugal illnesses such as roots rot. Soil amendment with sand, frequent watering, and breezy conditions that allow ample space can aid in the growth of lavender and its flowering in humid climates.

How Far to Space Lavenders in Pots or Raised Beds

Similar guidelines are used in deciding the distance to place lavenders in raised beds or pots with 2 feet being suitable for smaller varieties and 3 feet for the larger varieties.

But you could get away by placing the lavenders closer together when they are in pots because the air circulation tends to be more effective than when they are planted in the ground.

Lavender pots placed on gravel or patios are not as susceptible to the dangers from damp soil (as the raised bed and pots are better drainage) and there are likely to be fewer immediately present sources of moisture (such in wet or muddy soil) which can cause an increase in humidity or cause moist conditions in the area around the lavenders leaves.

So long as each plant gets enough sunlight it will be possible to place potted lavenders closer to each other. With pots, of course, you can alter their position and even move them further away in case theyre unhappy with their position.

For more details on how simple it is to do check out the following article by me: Growing lavenders using pots.

Raised beds can also be an excellent way to prevent issues with soil that retains water or low lying areas that are boggy. In the event that your yard is relatively open and has a breeze that is frequent, then you shouldnt have any issue planting lavenders closer to each other.

If you feel that the lavenders arent doing in the way they should, then you could move the lavender plants so that they are further apart into pots, or elsewhere in the garden. The best time to transplant lavenders is in the early spring.

Spacing different varieties of lavender in the process of planting

Lavender plants can differ in size, with some huge plants exceeding… while the dwarf cultivars can only reach…

Be aware that lavenders can only expand to their maximum size and show the most beautiful blooms when they are in the best conditions for growth.

The bigger the plant gets, the farther apart you need to place the lavender. This means that you are able to be able to space small lavenders more closely insofar as they dont deprive one other of sunlight.

The amount of sunshine each lavender gets each day is directly related to the intensity of the lavenders scent and bloom, so it is possible to plant them close to one another as insofar as they dont block sunlight from each other. This is why the use of dwarf lavenders is to plant decorative lower lavender hedges.

The huge varieties are utilized to decorate the garden and also to produce commercial lavender oils. A single one of these tall 40 inches (1 1 m) creatures can emit an enchanting scent that spreads all over the garden during the summertime.

It is recommended to plant varieties such as Hidcote Giant at least three feet from each other to get the most scent and flowers of the plants.

Three feet is an ideal distance to shield large lavenders from other plants that are large, and fences, walls or other garden features which could hinder air flow or cause an increase in humidity. The lower humidity and the more breeze that flows around the lavender, the more resistant it is to fungal diseases.

Key Takeaways:

  • Plant lavenders about 2 feet from one another.
  • The dwarf cultivars can be planted further to each other (18 inches to 2 feet) and the larger varieties are more vigorous and flower best when they are planted three feet away.
  • The spacing of lavenders by 2-3 feet will ensure that each plant is not fighting for water, light and nutrients, as well as space and air flow , so that each plant will produce the highest amount of flowers and sweet scents.
  • The potted plants and lavenders in raised beds can be placed slightly further apart because of the possibility of improved airflow and drainage, provided they do not cast shade over one another, as lavenders require full sun.
  • The more humid your climate, the farther apart you must plant lavenders. This is also true for warmer climates.
  • The spacing of lavenders between 2-3 away from one another will increase airflow, and thus reduce the chance of fungal diseases that can affect your plants.
  • Think about how easy it will be for you to reach your lavenders while deciding the best place to put them since lavenders require trimming every year at least to stop the growth of wood at the base and prolong their lives.

  • Spacing lavenders properly will improve the overall health of the plant as well as increase the number of flowers, aromas and oils.
