CARE GUIDE

How to keep Pulmonaria Montana.

Light

Mountain lungwort is native to habitats like forest understories and rocky sites, where it occurs in natural shade. It prefers partial sun but can tolerate full sun or full shade, illustrating its hardy and adaptable nature.

Water

Mountain lungwort thrives in cool, moist woodland environments and does best in soil that remains evenly moist. To ensure optimal health, it is recommended to water it weekly. This herbaceous perennial benefits from being grown outdoors and receiving natural rainfall. During its active growing season, its water needs increase, supporting vigorous growth.

Temperature

Mountain lungwort can adjust to a wide range of temperatures, but its distribution may still be restricted by different combinations of moisture and heat. It performs best in warm summer conditions with sufficient rainfall or watering. Extended stretches of cloudy, rainy weather or prolonged high temperatures can increase the chance of the plant dying. In winter, appropriate protection from cold can raise the plant's survival rate.

Fertilizer

The optimal time to fertilize a Mountain lungwort is in early spring, as it comes out of dormancy and begins active growth. Applying fertilizer supplies essential nutrients for healthy development. While Mountain lungwort has fairly low fertilizer requirements, a yearly application can improve its survival and encourage better, longer-lasting blooms.

Pruning

Mountain lungwort is known for its spotted leaves and early spring blooms. To keep the plant healthy and well-shaped, prune it in early to late spring by removing spent flowers and dead foliage. Light trimming is recommended, as it enhances both the plant's health and its ornamental appeal without the need for heavy pruning.

FREQUENTLY ASKED

Reader questions.

How should I water my Mountain lungwort in the best way?

To properly water the Mountain lungwort, it is best to use filtered water at room temperature. Tap water may contain harmful particles, so filtering it is important. Since the plant comes from a warm environment, it is advisable to use water that is at room temperature or slightly warmer to avoid shocking it. It is not recommended to water the plant from above, as this can lead to issues with its foliage. Instead, it is better to apply the filtered room temperature water directly to the soil until it is completely saturated. This helps the plant by providing moistened roots and aiding in the spread of nutrients throughout the soil.

What are the sunlight requirements for Mountain Lungwort?

Mountain Lungwort thrives under specific sunlight conditions, preferable to its native habitat, such as forest understories or rocky areas where it receives natural shade. It requires partial sun, about 3-6 hours of sunlight per day, but can also adapt to full shade conditions, where it receives less than 3 hours of sunlight per day. It's crucial to observe how sunlight moves through your garden to ensure plants receive the right balance of light and shade, as this significantly impacts their growth and health.

What can I do if I give my Mountain lungwort too much or too little water?

Overwatering is the main issue for the health of your Mountain lungwort. When it receives too much water, its stems and leaves may wilt and turn yellow, and it can develop diseases like root rot, mold, and mildew. Underwatering is less common, but it can make the leaves brittle and brown. It's important to notice signs of overwatering early to prevent irreversible damage. Reduce watering if you see early signs and check the soil drainage. If your Mountain lungwort lacks water, simply increase watering until symptoms improve.

How can artificial lighting be used for Mountain Lungwort?

When natural sunlight is insufficient, especially during winter or in less sunny indoor spaces, artificial lighting becomes essential for Mountain Lungwort's growth. Optimal growth is supported by adequate lighting, achievable through artificial sources such as LED lights, which can be customized to provide specific wavelengths of light needed by the plant. For full sun plants, a provision of 30-50W/sq ft of artificial light is recommended, while partial sun and full shade plants need 20-30W/sq ft and 10-20W/sq ft of artificial light respectively. The light source should ideally be placed 12-36 inches above the plant to mimic natural sunlight, and it's important to mimic the natural daylight hours, ensuring most plants receive 8-12 hours of light per day.

How often do I need to water my Mountain lungwort?

If your Mountain lungwort plant is in a pot, the most precise way to determine if it needs water is by checking the moisture level of the soil. Simply stick your finger into the soil and if the top two to three inches feel dry, it's time to water it. If you have the Mountain lungwort plant in the ground outdoors, you can use the same method to test the soil. Once again, if the top few inches of soil are dry, it needs to be watered. Typically, during spring and early fall, you will need to water this plant about once a week using this method. However, during extremely hot weather, you may need to increase the watering frequency to twice or more per week. It's worth noting that mature, well-established Mountain lungwort plants have a commendable ability to tolerate drought.

What are the symptoms of light deficiency in Mountain Lungwort?

When Mountain Lungwort doesn't receive adequate light, several symptoms may manifest, including smaller new leaves, leggy or sparse growth, faster leaf drop, no new growth, lighter-colored new leaves, chlorosis, sunscald, leaf curling, wilting, and leaf scorching. These symptoms range from reduced leaf size and abnormal growth patterns to the physical appearance of leaves turning yellow, pale, or getting scorched due to excessive sunlight. Each symptom signifies the plant's struggle with its environment, indicating the need for better light management.

How much water does my Mountain lungwort plant need?

When watering your Mountain lungwort, don't be afraid to give it a generous amount of water. Wait until the top two to three inches of soil are dry, then water the plant thoroughly, making sure to saturate the entire soil. You should add enough water that excess water flows out of the drainage holes at the bottom of the pot. If you don't see excess water draining, it means you haven't watered enough. However, be careful not to let water accumulate in the soil, as this can harm the plant. On the other hand, if water doesn't drain well from the pot, it may indicate poorly draining soil, which is bad for the plant's health. If the plant is outside, one inch of rain per week is enough.

What solutions are recommended for light deficiencies in Mountain Lungwort?

Addressing light deficiencies in Mountain Lungwort involves a combination of moving the plant to sunnier spots gradually, using artificial light, reducing sun obstructions, and transplanting. Indoors, if the plant is large or not easily movable, you might consider using artificial light, like keeping a desk or ceiling lamp on for at least 8 hours a day or using professional grow lights for sufficient light exposure. Outdoors, it's key to move your plants gradually to sunnier locations to avoid sunburn, and for ground plants, reducing obstructions like pruning trees or transplanting to sunnier spots can significantly improve sunlight access. It's crucial to adapt these strategies to your plant's specific needs and environmental conditions.

How do I water my Mountain lungwort as it grows?

The water needs of the Mountain lungwort can change depending on growth stages. In the first few years or after transplanting to a new location, you need to give more water than usual. During this time, the plant focuses on sprouting new roots for future growth, so they require extra moisture. After a few seasons, the plant will need less water. Another stage that requires more water is during the bloom period when flower development uses a significant amount of moisture.

How do I water my Mountain lungwort throughout the year?

The Mountain lungwort has its highest water needs in the hottest months of the year. During summer, you may need to water this plant more than once per week, depending on how quickly the soil dries out. However, during winter, the plant enters a dormant phase and will require much less water. In fact, you may not need to water it at all during the winter months. If you do choose to water it during winter, make sure to do so no more than once per month to avoid the risk of disease.

How does watering my Mountain lungwort plant inside compare to watering it outside?

The Mountain lungwort is commonly grown indoors by gardeners who don't live in temperate or tropical regions. If you grow it in a container, keep in mind that the soil may dry out faster compared to ground soil. Also, if you have drying elements like air conditioning, you'll need to water your Mountain lungwort more often than if it were planted outside. In outdoor conditions, you may not need to water it much at all if there is regular rainfall. However, if you grow this plant indoors, you'll need to water it more frequently since you can't rely on rainwater to soak the soil.
