Can I Grow Roses and Lavender Together?

Lavender is a good companion plant to Roses since they bloom around the same time. They have similar preferences for growing like full sun and well-draining soil. But lavenders prefer soil that is dry with less water and less soil fertility than roses, so it is essential to plant both roses and lavenders about 2 feet away.

The spacing of roses and lavenders allows you to take care of the unique needs of every plant, so that they will produce the best blooms and the most fragrant scent.

Here are five tips to grow lavenders using roses.

  1. Plant roses and lavenders 2 feet from each other (therefore the plants don’t have to fight for light, airflow and water, as well as nutrients, etc.)
  2. Determine the soil conditions that are suitable for roses and lavenders (lavenders require more drainage than roses)
  3. Feed Roses , but they are not lavenders (lavenders prefer medium to low fertile soil)
  4. More often, water roses than lavenders (Water roses every week, lavenders each two weeks)
  5. Include organic mulch on roses , but not lavenders. (Conserves water and provides fertileness to the roses, while lavenders like soil that is dry).

Lavenders and Roses are stunning when they are in bloom. The different conditions for growing between the two flowers can be fixed by certain adjustments, so read on for tips on how to make sure both plants are at their highest potential.

3 Feet Away from Roses

Roses and lavenders can only thrive and show the best flowers when they each have sufficient room in your garden. To get the best results, grow lavenders and roses, you need 3-4 inches of room.

This will allow each plant enough room to have:

  • The highest amount of sunlight (both roses and lavenders require full sunshine)
  • Access to enough nutrients so that every root system is competing against each other. (Roses are very nutrient-dense and don’t enjoy competition).
  • Both roses and lavenders like airflow to the foliage since this reduces the risk of fungal diseases in both species.
  • The lavender and roses both benefit from annual pruning and deadheading. This means that space between plants allows you to be the gardener to take care of every plant without being stung by the rose thorns! (Always wear gloves with gauntlets for safety while working around roses).
  • A space of 2-3 feet for each plant can help to further customize your soil requirements for every plant (moist soil suitable for roses, and dried soil to grow lavenders) You can also water the roses without watering the lavenders , so both plants are healthy.

Both roses and lavenders require the space needed to ensure that they’re not putting shade on one another over the course of a summer’s day, which can hinder the growth, blooming and fragrance.

Soil pH

There is a little similarities in the pH of soil that both lavenders and roses like. Lavender is able to grow in soils that has pH 6.5-8 and roses can thrive in soils with pH 6-7.

If the soil you are growing in is less than the pH of 6.5 (acidic) is it is not suitable for the cultivation of lavender of any kind, so it is recommended to conduct a soil test prior to purchasing or plant lavender. For more details about how to conduct this test, check out my article on lavenders and soils that are acidic.

The English lavender plant is not just more robust in cold temperatures , but it also grows better than French lavenders in moderately acidic soils with a pH of 6.5 while French lavenders may begin to exhibit signs of stress, like a slow growth rate in these soils, so when it comes to Rose planters, it is best to choose English lavenders. (Read for more details about differences in English lavenders and French lavenders).

The majority of garden soils tend to have a pH of around 6-7 because this is the most common pH for organic matter after it has been completely decomposed. However, we it is always recommended to test your soil prior to planting since soil testers are available at a reasonable price on Amazon, which is less than the price of roses and lavenders that might not last as long if the soil isn’t suitable.

Do not feed the Lavenders when feeding roses

There is a stark contrast between lavender and roses in regards to their preference for soil fertility. Lavender thrives in soils that have a low amount of nutrition (read my article to find out reasons why lavenders don’t require feeding) while Roses thrive and produce the highest amount of flowers in high fertility soils. They also will benefit from fertilizer addition.

Feeding lavenders can encourage the growth of their foliage, but even at the expense of flowers since lavenders are adjusted to grow in soils that are sandy and have low fertility.

  • Lavenders bloom and give off the most delicious aroma when they are in soils with moderate to low fertility.
  • The best roses bloom when they are planted in fertile soil. They also receive an early feed in the beginning of spring.

This highlights the necessity of maintaining a distance between roses and lavenders within the same flower bed to help you pinpoint the ideal soil conditions to each flower.

The gravel or sand you use to amend the soil prior to planting the lavenders can help to improve your soil’s fertility since the sand is not a major source of nutrients, which can create the ideal conditions for the growth of lavender.

Three feet of space will provide enough space between plants so that you can apply fertilizer to your roses in the spring, without damaging the soil that lavenders need.

I personally suggest that you utilize a granular fertilizer like miracle grow continuously released Rose as well as Shrub plant food instead of liquid fertilizers since you can control where you distribute the food, and there is less chance of increasing the fertility of the entire flower bed, which can reduce the likelihood of lavender flowers blooming.

Both lavenders and roses bloom in the spring and summer which means you can expect an amazing multi-species flower.

Localise Soil Conditions for Roses and Lavenders

Lavenders benefit when they are planted about 2 inches apart from the roses since this can help you identify the soil conditions and the soil water content of every plant.

Both roses and lavenders prefer soil that drains well. The distinction is that roses prefer to be in soils with an organically high content. Soils that are high in organic material (compost) are sufficiently porous to permit the excess liquid to flow away from the roots, but it also absorbs and retains the moisture surrounding the roots.

This is advantageous for roses since they need their roots to pull up water from the soil whenever they require it without the soil becoming saturated.

The lavenders, however, require the soil to be more dry. In their natural Mediterranean region, lavenders thrive in soil that is sandy and well-draining and are likely to die from root decay in soils that are rich.

The most important thing to do when growing roses and lavenders is to alter the soil to fit the plant’s needs:

  • In the process of planting the lavenders, dig an 18 inches wide and depth. Add gravel or course sand to the hole , so that about a third of it is made up of sand and the remaining two thirds comprise compost.

This will increase drainage in the soil, and Sand does not hold on to moisture the as compost does, so there is less material retaining water around the roots, which can stop the plant from developing root decay.

Sand can also assist in providing the low to moderate fertility conditions required by lavenders for them to bloom and release a strong scent.

(For more details, read my guide on the best mixture of soil for the lavender).

In contrast, roses prefer being placed in soil which has been heavily amended with organic matter such as leaves mould and compost, and well-rotted manure since this helps to hold in water and supply plenty of nutrients to the soil, which ensures they remain well-nourished and produce the best flowers.

Water Roses more often than Lavenders

One of the main distinctions between roses and lavender is the amount of they drink.

  • Lavender is a drought-resistant plant that thrives in hot temperatures with intense sunshine and very little water. Established lavenders need to be watered once every two weeks during the growing season, if there isn’t any rain.
  • They also thrive in hot temperatures with plenty of sunshine, but they need plenty of water. The roses require a good bath every week throughout the growing season. They will require watering every three days in periods of extremely hot weather.

The difference in preference for watering further emphasizes the need to planting your roses and lavenders at the correct distance.

Make sure to direct the water towards the bottom of every plant (so that you don’t over irrigation of the plant) and every plant will appreciate getting a good soak every time because this helps roots grow into the soil.

For lavenders, over-watering is always a bigger issue than under watering, so it is essential to adjust to the needs of every plant.

Add Mulch to Roses not Lavenders

One of the main advantages of the planting of lavender and roses 2-3 inches apart, is the fact that you have enough room to add mulch for roses, without impacting the lavender.

The roses love the installation of mulch during the spring due to:

  • Mulch helps conserve water during the summer months to help keep it dry
  • Mulch can improve the fertility of the soil, which will enhance flowering and also increase roses resistance to illness.

Apply the mulch and a 1 inch layer of it ( garden compost, leaf mould and rotted manure are excellent options) on the rose’s soil.

Make sure to leave a 6 inch-diameter of soil between the mulches and the rose’s wood stem, as the above ground wood is not a fan of being immersed in wet materials.

The lavenders, on the other hand prefer that the soil remain dry, so ensure that the mulch is kept only in the vicinity of roses. A mulch that retains moisture can only create conditions that make the lavenders more susceptible to fungal diseases, so make sure that the soil is free of any mulch or fallen organic matter (such as leaves in the fall).

Key Takeaways

  • Lavenders can be cultivated alongside roses and look stunning when they are blooming simultaneously However, there are certain differences in the ideal conditions for growing. With a few adjustments and care both plants will thrive.
  • The most important thing is to plant lavenders about 2 feet from roses, as this will allow each plant the space needed to breathe, sun, nutrients, and water. You can take into account that lavenders prefer dry soil (amend by adding sand to allow for rapid draining) and roses that prefer soil that is moist and has more organic matter.
  • Roses and lavenders have distinct needs for water, so don’t regularly water them in the same way. The lavenders are drought-resistant and need only be watered every two weeks when there isn’t any rain. The roses require watering regularly and every 3 days during extreme heat.
  • The planting of roses and lavenders 2 feet apart allows for feeding the roses while giving the roses food. Lavenders like low to medium fertility soils, while roses prefer heavy feeders.
  • Use mulch on roses to help conserve water during the summer heat and to add fertility for the soil. They are easy to maintain in this respect and don’t require any mulch since they prefer dry conditions.
