Where to Plant Primrose
Knowing where to plant them is essential to getting a healthy blooming flower. This includes the soil and season.
Soil
Primroses prefer moist and organic-rich soil. The pH of the soil should be a little acidic, between 6.0 and 6.7. The area should not be too watery. Primrose growing requires well-drained soil, so avoid clay soil, as it can block water drainage.
Season
A cool climate is perfect for primroses, so it is best to plant them in fall or early spring, right after winter. If you live in areas with mild climates, it is best to plant your flowers right before the start of winter so they can firmly dive their roots.
Placement
While primroses like a slightly cool climate, they can endure sunlight. However, too much or direct sunlight can scorch them. An ideal place to plant them would be where the morning light is great, but it stays in the shade for the rest of the day.
Primroses are toxic to some animals, so use caution if you have pets and are considering adding primroses to your landscape.
How to Grow Primrose
Growing a plant has several stages, from planting to caring for it. We will go over all these step-by-step.
Pruning
Pruning the primrose is essential before planting it for better growth.
- Take the root ball and look for dead and damaged leaves, which may be dark or yellow. Pick them out using your hand or a hand pruner.
- Look for the flowers that have bloomed completely and are now looking dead; pick them out. This will leave us with fresh buds and blooming flowers.
Planting a Primrose
We’ve already discussed where to plant primrose, so let’s move on to how to plant them.
- Dig the compost-rich soil about 6-8 inches deep using a garden fork. Then, dig a hole using a hand trowel. The hole should be a bit larger than the root ball so it fits in completely.
- Put the root ball inside the hole, filling the hole with soil and mulch until the crown area, so the leaves and buds are not inside the soil.
Wear garden gloves while working with soil, as it contains different types of fertilizers. Contact with the plant can cause skin irritation, and sometimes, insects can also emerge.
Before excavation, call 811 to check for underground utilities.
How to Take Care of Primrose
Once planted correctly, the next important step is to ensure proper care to help it grow healthy and strong.
Watering and Fertilizer
Primrose are very low-maintenance plants but still need proper watering and fertilizers.
- Primroses prefer moist soil, but they should be partially filled with water. A good time to water them is when the upper layer feels dry, which means you should sprinkle some water on them. Water them more in the dry season.
- They should be fertilized once a month during the season in which they grow rapidly, especially from spring to summer.
- Organic mulch like shredded leaves, pine needles or bark is ideal for primrose which also helps in keeping the weeds away while giving sufficient nutrients.
Protecting from Pests and Diseases
- Aphids, slugs, snails and spiders are common pests that can affect primroses and stunt their growth. They can easily be controlled by spraying insecticidal soap and organic slug repellents according to the package instructions.
- Fungal diseases like white powder and rot roots can develop in these flowers when air and water circulation are not properly maintained. To prevent these diseases from developing, fork the soil for air circulation and maintain a proper drainage system.
Primrose in Containers
Things to remember if you plan to plant your primrose in a container.
- The container should have holes at the bottom for proper water and air circulation. It should be big enough to contain a primrose, as it tends to form a cluster in full bloom.
- Since they are in a container or pot, not in the ground, they tend to dry quickly, so keep spraying them with water from time to time. Fertilizer should also be used every 3-4 weeks.
Seasonal Maintenance
Now that we have learned how to grow primrose, it is important to look into seasonal maintenance.
- In cold or winter climates, cover the roots with a thick layer of mulch and if that is not enough, consider covering them with garden fabric.
- In spring and summer, prune them occasionally when they are in full bloom and provide them with shade on extremely hot days.
