When to Plant

Primulas are best planted in spring or autumn, where temperatures are cool, and the soil is moist.

How to Plant

Planting Primula Modules & Pots 
 Our modules and pots are incredibly easy to plant and maintain. Whether you’re growing them directly outside into the border or in a container or keeping them indoors over winter, our modules are a breeze to care for from the moment they arrive. 
- Dig a hole in the border that’s big enough to house the entire module. If planting in pots, fill a large pot halfway with potting soil and then make several holes that can hold the modules. Do this until the top of the soil from the module is just below the top of the pot. 
- Fill around the modules with soil and firm them down gently.  
- Water well and you’re done!   

Where to Plant

Make sure you plant your primulas somewhere partially shaded, and they’re in moisture-retentive soil. Many primulas prefer a shady spot, but some can tolerate direct rays.

Feeding Primula

Native primroses and cowslips need little attention to keep flowering. However, other varieties can flower in abundance for longer and need extra help to do so. As soon as you see their first buds appear, feed them with diluted tomato feed once every ten days until the flowers open.

When to Water

Water well after planting and continue to water regularly – especially in periods of intense heat. Reduce watering in the tail end of summer/beginning of autumn.


If left after their flowers are spent, primulas will self-seed. This allows them to reappear the following year, giving you a bigger display!  
However, if you would rather them be an annual only, deadhead spent flowers. 

Dividing Primulas

Primulas and primroses will need dividing every couple of years, or once they’re heavily congested. As they self-seed, they will grow in numbers, and without any intervention, they can get out of hand. Many flowering issues can arise when plants get overly congested, so it’s in your best interest to divide them when you notice this happening.  
To do this, simply lift the plants out of the ground, divide them into halves and plant them further apart in the garden.   

Common Issues & How to Solve Them

Primulas aren’t often bothered by pests or diseases. However, keep an eye out for primula leaf spot. This appears with spots in yellow/orange colours. Under the leaves can also hide white fungal growth. Pick off any affected leaves once you notice this to mitigate the problem. 

When do they Flower?

Most primulas will flower between March and May. This may differ depending on the type you have purchased but do be extra sure, you can see their flowering months on their online product pages.
