How To Care For The Lavender Plant In Colorado

Lavender Plant care

To make sure your Lavender plant is growing well and thriving in your care, you need to ensure that you keep the plant in the perfect living conditions and provide the plant with everything it needs to grow big and stay healthy and happy.

Luckily, this is easy to do with Lavender plants, especially in Colorado, as this state has a climate that is almost perfect for this plant. So, let us go through these living conditions and what you need to do to keep your Lavender plant happy.

Temperature And Humidity Requirements

Lavender plants can handle a wide range of temperatures. The main factor that will most likely kill a Lavender plant is soggy, damp soil more than it is the cold. However, if you can, you should still bring your Lavender plants inside when it snows, as this can affect the dampness of the plant’s soil.

Lavender does not need high humidity to survive; if the humidity level is too high, this can cause problems for the plant. High humidity levels will keep the plant’s soil damp for longer than the plant can manage it, leading to fungal disease and root rot.

Ensure you plant your Lavender with plenty of space between the plants to help increase the airflow around the plant, which will help keep the soil dry when there is high humidity.

Watering Guide

Lavender is a plant that can handle drought situations like a champ, which is part of the reason it is so easy to care for, and this plant is extremely resilient.

With Lavender, you only need to be worried about watering them when they are still establishing themselves; once they are well-established, they can handle extended periods without water, which is perfect for Colorado’s summer climate.

When the plant establishes itself, you should water it every other day; then, when it has settled in, you can water it once a week in spring and summer and once every two or three weeks in fall.

In Colorado, the winters become extremely cold, and it can snow, so during this time, you do not need to water your plant more than once a month, and you should bring the plant indoors if you can.

Light Guide

All Lavender plant owners should know that Lavender is a sunlight-loving plant, no matter which species you are growing or which state you are growing it in. Even if the Lavender plant is not in its active growing stage in the fall and winter, the plant will still need a lot of bright sunlight to stay healthy.

Lavender is a full-sun plant and needs to be treated as such, which is easy to do in Colorado’s climate. Whether you are keeping your Lavender indoors or outdoors, you need to ensure the plant receives the correct amount of sunlight daily.

If the plant does not receive the right amount of daily sun, the Lavender plant could die. If you keep your plant indoors, you can place your Lavender plant on a bright, cool windowsill, or you can use a grow light to help supplement the natural light that the Lavender needs.

Soil And Potting Requirements

Caring for lavender

Lavender plants need well-draining soil that is kept on the drier side as this plant is extremely prone to root rot. For Lavender plants, lean soil is the best as this will help encourage a higher concentration of oils.

So, if you want your Lavender to have a lovely strong smell, you need to go easy on the organic matter you place in the plant’s soil. If you are using a regular potting soil mix for your Lavender plant, ensure you mix in some sandy soil to help drainage.

You should make sure that your soil is alkaline or chalky, as this will help enhance the plant’s fragrance. If the pH level in the soil is lower than 6.5, this will cause the plant to have a shorter life. This plant needs good soil drainage; you need to plant it in a pot with plenty of drainage holes to keep your Lavender happy.

Fertilizer Requirements

Fertilizing your Lavender plant is not a necessary step in caring for this plant as it prefers lean soil, but you can fertilize your Lavender plant if you would like to. It is always good to plant your Lavender plant in healthy and fertilized soil, so you can add a handful of fertilizer into the soil first when you plant your Lavender.

This is especially helpful in Colorado as the ground can sometimes be dry and nutrient deficient. If your Lavender is planted indoors, then you can use a multipurpose liquid fertilizer or a granular fertilizer; if it is planted outdoors, then your usual garden fertilizer should be fine.

Potting And Repotting

Even though Lavender plants have a large spreading root system, they do prefer to be slightly root-bound. You should plant your Lavender in a pot that can fit the plant’s root ball with 3 to 4 inches of space to spare around the roots.

The plant needs to have plenty of drainage holes, and you can use a clay or terracotta pot to help wick moisture away from the plant’s roots. Lavender has a medium growth rate, so you need to repot the plant around once every two years.

Propagation Facts

You can propagate your Lavender using two different styles of cuttings. One is softwood cuttings, and the other is hardwood cuttings. Both cuttings will use the propagation method as any other form of propagation through cuttings; the only difference is where you take the cuttings from.

With softwood cuttings, you cut a three-inch segment from a healthy shoot, remove the leaves from the last two inches, and scrape off the skin. Then you carry on with the standard propagation method. Hardwood cuttings are cut just below a leaf node and then follow the above process.
