The Soil

About soil condition, mountain laurel flower (Kalmia latifolia) prefers acidic, organic soils with high moisture content and good drainage. They are intolerant of chalk and lime. If the soil is too rich, the plants will be lanky and produce fewer flowers.

Light condition

Not too different with other flowers, mountain laurel flowers require sun to grow properly. The amount of sun required depends on the variety of mountain laurel, but all need at least some sun to produce flowers. Too little sun results in fewer, smaller flowers.

Ideal Temperature

The temperature condition that is most favorable for the growth of mountain laurel flowers is between 68 and 72 degrees Fahrenheit. This range of temperatures is optimal for the plant to produce blooms. Anything above or below this range can result in the plant taking longer to flower or produce fewer blooms. Mountain laurels are also sensitive to frost, so it is important to protect them from any cold weather that might be forecasted.

Ideal Humidity

Ideal humidity condition for this plant is 50%-70%. The leaves of mountain laurel will start to brown and curl if the humidity drops below 50% for an extended period of time. If the humidity is too high, the leaves will become covered with mold and mildew.

The Fertilizer

For the fertilizer, usually the plant does not need too much. However, if the plant is not looking too good, then you might want to give it some extra nutrients. You can use any type of fertilizer that is made for acid-loving plants. As for the roots, they are very strong and can anchor the plant very well.

Light requirement

Pruning mountain laurel is important to promote healthy growth and prevent the plant from becoming overgrown. Laurel flowers best when it is pruned regularly. The best time to prune mountain laurel is in late winter or early spring, before the plant begins to bloom.

Plant Propagation

Propagation is usually by seed, which is sown in spring in a cold frame, though it can also be done by division of mature plants in spring or autumn. Seedlings take three to four years to flower. Plants grown from seed form a bushy shrub.

Growth Rate

Usually, the plant growth rate is quite fast. This shrub can reach its full potential size in as little as three years. Although it is possible for some mountain laurels to grow even faster, the average growth rate is still quite impressive.

The Problems

Common problems for this kind of plant are over watering and under watering. If the soil is too wet, the roots will rot. If the soil is too dry, the plant will wilt. Too much sun will scorch the leaves, and too little sun will cause the plant to become etiolated.

Growing Tips

  • Make sure to plant mountain laurel in soil that is well-draining and rich in organic matter.
  • Water regularly during the first growing season to help the plant establish a strong root system.
  • Fertilize mountain laurel yearly with an organic fertilizer.
  • Prune mountain laurel regularly to encourage new growth and to keep the plant compact.
  • Deadhead mountain laurel flowers regularly to prevent seed formation and encourage more blooms.
  • Protect mountain laurel from strong winds and harsh winters by planting in a sheltered location.
  • Mulch mountain laurel heavily in the fall to help insulate the roots during the winter.
  • Try to avoid disturbing the roots of mountain laurel when transplanting or dividing the plant.
