They’re so easy to care for, and I think little Lavender should be in every garden.

In general, Lavender topiaries are very easy to care for. To grow appropriately, they need well-draining soil and 3-4 hours of bright indirect sunlight daily. Low humidity, moderate temperature, frequent watering, and proper fertilization are its other basic requirements.

Native to the rugged climatic condition of Europe, the Lavender Topiary is reasonably hardy, and you can grow it both indoors and outdoors.

If you acquaint yourself with the basics of caring for a Lavender Topiary, you will be rewarded with a beautiful plant that gives off a soothing, relaxing fragrance.

Continue reading to find out how to cultivate and care for a Lavender Topiary indoors and out.

Difference Between a Typical Lavender Plant and a Lavender Topiary

Lavender Topiary is made from Lavender plants that are properly trimmed, cut, and trained to grow from the top.

Like a standard tree, it has a bare wooden stem with branches, leaves, and flowers growing from the top.

Depending on your taste, you can trim it to be rounded or spikey, or give it any other look you like.

Caring for your Lavender Topiary

Growing a Lavender Topiary is similar to growing other plants.

It can tolerate most growing conditions but will do best when provided with well-draining soil and adequate sun.

This plant is pretty low-maintenance and easy to care for. So, it will serve as a decoration for many years if cared for properly.

Let us go through a few factors that dictate how your plant turns out to be.

1. Light Requirement

Providing your Lavender plant with adequate light is one of the essential aspects.

Your Lavender will thrive if you keep it at a windowsill or a South-facing window where it gets a minimum of 5-6 hours of full sunlight daily. 

If you don’t have a South-facing window, try locating your plant in a West window.

If you want to plant your Lavender Topiary outdoors, keep it where it receives at least 6 hours of full sunlight.

Wherever you put your plant, remember to rotate the pot weekly to promote even growth and flowering.

Try not to put your plant at a place where it will be overshadowed by shade or any other plant.

Without enough sunlight, your plant will start to show weak growth and cease to produce any flowers. Unfortunately, this also makes it more vulnerable to diseases.

2. Watering Requirement

Due to its hardiness, it is incredibly resistant to drought stress once appropriately established.

Drench the soil thoroughly when watering and allow it to dry out slightly between waterings.

As Lavender is a native plant to the Mediterranean, it prefers to stay moist but not wet.

This plant is highly susceptible to diseases like root rot. So, overwatering can quickly jeopardize your whole plant.

To know when to water your plant, check the top 1-inch of the soil with your finger. If it is wet, then there is no need for watering.

Water once or twice a week when the plant is newly established. After it matures, you need to water it at least two to three times a week until the buds form.

Cut back to once or twice weekly until the time of harvest.

In winter, lessen the frequency of watering. Only water if the top 2-inch of the soil is dry.

Note: Avoid getting your plant’s leaves wet to prevent fungal and mold growth.

3. Temperature and Humidity

Proper temperature encourages healthy growth and frequent flowering.

The ideal room temperature for your Lavender Topiary is 70°F (21°C) during the day and 50-55°F (10-13°C) at night-time during its growing season.

In the winter season, it enjoys a temperature of 60-65°F (15-18°C) during the day and 45-50°F (7-10°C) at night.

Keep your plant in a place where it receives ample direct sunlight daily. It will help to maintain sufficient temperature for your plant.

Unlike most other tropical houseplants, Lavender Topiary instead prefers a low-humid environment.

Lavenders can’t tolerate high humidity in both the soil and the air. However, most households have an average humidity of 30-40%, suitable for growing Lavenders.

Lavender Topiary doesn’t need any additional sources of humidity like pebble tray or humidifier to thrive.

Being a hardy perennial herb, it can do well on its own, and you might only damage it if you make the environment more humid.

Provide good ventilation and air circulation but avoid putting it in direct line of heaters or air-conditioners.

4. Fertilizing your Lavender Topiary

Generally speaking, Lavender Topiary requires a bit less fertilizing than most other plants.

Over-fertilizing is an issue for most amateur growers that can lead to excess foliage, yellowing, and no bloom.

Most gardening experts recommend fertilizing your plant once, generally before the start of the growing season (before springtime and summer).

Most gardening experts recommend putting an inch of compost around the plant as an organic fertilizer which can provide enough nutrients for your plant year long. 

If you prefer to buy your fertilizers, then liquid fertilizers like Lavender & Rosemary Fertilizer or any organic Phosphorous-rich NPK fertilizer like Neudorff Azet Lavender Fertilizer is ideal.

Follow the instruction manual on the back for proper growth and to avoid over-fertilizing.

5. Pot Size and Material

Lavender Topiary grows excellent in pots and containers. However, you need to consider a few things before you choose the best pot for your plant.

Some Lavender species can have a modest height of 16-18 inches, whereas others can reach 30-36 inches.

For all the Lavender species, it is recommended that you grow your plant in pots about 12-16 inches in diameter and have proportional depth.

Similarly, a Ceramic or Terra Cotta-style pot is the ideal choice that won’t allow the soil to dry off as much.

6. Potting Mix

Lavender grows best in a loose, friable mixture with good water draining and aeration capacity.

Although most plants prefer compost-rich, humus, and soil with organic materials, Lavender likes sandy, gravelly, rocky, and almost poor soil types.

It prefers slightly alkaline soil with a pH range of 7.0-8.0.

You can make your Potting soil by mixing:

  • One part compost
  • 1 part perlite
  • One part coarse sand
  • 1 part fine soil

Tips: You can add a few bits of eggshells or lime depending on the amount of soil to adjust the pH to become alkaline.

If you prefer to go the commercial route, you can buy potting soil mixed specially for Lavender on Amazon.

7. Repotting Lavender Topiary

Lavender Topiary does not need constant repotting if you have already used a big enough pot size to plant it.

If you Lavender starts to outgrow the pot, you can repot it in a new one.

However, some people suggest repotting Lavender once an entirely unnecessary year. It can also cause stress to your plant and do more harm than good.

In general, the Lavendar topiary can be repotted once every two years to prevent it from becoming root-bound.

Repotting any plant is done mainly for two reasons: when the plant starts to outgrow and when the soil lacks nutrients.

If you have already used an ideal pot size, repotting is redundant.

As the Lavender plant does not need nutrient-rich soil, it is also of no good to keep repotting your plant in new soil every year.

Follow the below instructions to repot your Lavender Topiary:

  • Select a pot size that is at least 12-16 inches in diameter.
  • Add small stones or pebbles to the bottom of the plant for better drainage.
  • Select a good potting mix and fill the pot with a couple of inches of soil.
  • Take off your Lavender Topiary carefully from the other pot and place it in the new one.
  • Fill the pot with a couple of inches of soil and firmly press it to remove air pockets.
  • Thoroughly water your plant.
  • Place it where it gets at least 6-8 hours of sunlight.

8. Troubleshooting Lavender Topiary

If not provided a suitable environment, then your Lavender Topiary can face a myriad of problems.

It can result in wilting, yellowing of leaves, root rot, and in some severe cases, death of the plant.

Some of the significant factors that contribute to these problems in your Lavender Topiary are:

  • Overwatering your plant
  • High levels of humidity
  • Lack of enough light
  • Wrong Soil pH
  • Too much pruning leading to woody growth
  • Root rot due to the bad soil mix
  • Pests like spittlebugs or froghoppers.
  • Lavender Shab disease
  • The wrong type of Lavender for your climate

If you follow the care routine mentioned in this article, you won’t have to worry about your Lavender Topiary facing these problems.
