Evening Primrose Care Guide
Taking care of the Primrose plant can be pretty easy. The average maintenance plant has simple light, water, and soil requirements. Its delicate flowers are prone to a few minor insect infestations. But they are sturdy plants.
Light Requirements for the Evening Primrose
Although the Evening Primrose blooms at night, it does need full sunlight. A minimum of 6 hours of direct sunlight a day is needed for a thriving plant. Lack of proper direct sunlight can hinder its flowering blooms. It can also tolerate exposure to filtered sunlight.
The best spot to grow your exotic primrose plant would be a sunny window. Placing the potted plant next to a south-facing window should be perfect. You can also opt for a west-facing window as that makes a great spot.
It is worth noting that the harshest sun rays can damage its delicate leaves. This is why you should provide some light covering when growing outdoors.
Water Requirements For The Primrose Plant
The watering schedule should depend a lot on the climate. During the hot season, you should aim to water the primrose often. This can be done once or twice a week. But on cool days or cold climates, watering should be less.
Evening Primrose roots do prefer a little moisture but they hate soggy soil. This is why you should always check the moisture level of the soil first. If after checking the soil feels almost dry, you can then water the plant.
To help, you can try feeling the soil with your finger. If the topmost part of the soil feels dry, then water. Always use dechlorinated room temperature water. Rainwater is also perfect but avoids tap water. It is filled with chlorine which could harm the leaves.
Soil Requirements for the Evening Primrose
A well-draining soil is needed for the Evening Primrose. You can achieve this with sandy soil or a good soil mix. The soil should also contain a little mulch which should cool the roots. Aim for a soil type that is a little acidic. You can get that with a little peat moss.
In addition to good soil, you need a good pot. Ensure the pot being used has sufficient drainage holes. This should help with getting rid of the excess water gotten from watering.
Temperature and Humidity Requirement For The Primrose Plant
Avoid growing the primrose plant in a hot and humid environment. They enjoy the cool air of the night, which is why they bloom at night. It is best to avoid misting your primrose plant often. Instead, leave them in regular room conditions.
The same goes for temperature needs. The regular room temperature should be perfect for Evening Primrose. But ensure they are protected from frost as they are not frost-hardy. An ideal temperature range should be between 20 and 30 degrees Fahrenheit.
Fertilizer Requirements For The Primrose
Evening primrose do not need fertilizer. Avoid using fertilizers as this can cause chemical burns. If your plant soil lacks nutrients, then add organic compost to the mix.
