The English primrose, which is also called either Primula acaulis or Primula polyantha, is one of the most common primrose varieties. They have thick, dark green leaves and clusters of brightly coloured flowers that grow just above the leaves. Unlike other flowering plants, the primrose blooms during the early winter months as well as early spring. Whether the English primrose is planted outdoors or indoors in pots, proper fertilisation is necessary to promote blooming and to encourage the health of the plant.

Things you need
- 3-20-20 liquid plant fertiliser
- Granular fertiliser (optional)
Fill a pitcher with a liquid plant fertiliser, such as 3-20-20, that is designed for blooming plants. Refer to the package instructions for the proper amount of fertiliser to use for the number of primroses that you have.
Add water to the pitcher to dilute it as instructed by the fertiliser packaging. Typically, liquid fertilisers are diluted in 1 gallon of water.
Pour the fertiliser mixture slowly into the soil around the base of the English primrose until you have emptied the pitcher. If you are feeding more than one primrose, divide the liquid among all of them as equally as possible.
Repeat the fertiliser application in this same manner at least once per month during the blooming period.
Tips and warnings
- Do not use a fertiliser that has a higher first number on the front of the package, since these contain more nitrogen. While high nitrogen levels won't harm the primrose, it causes the leaves to grow taller than the flowers.
- You can also mix granular fertiliser into the soil before planting English primroses at a rate of 1 cup of fertiliser per bushel of soil.
