Are Cape Primrose Indoor or Outdoor Plant?
Cape Primrose (scientifically Streptocarpus species) is a tropical to subtropical perennial plant naturally thriving in Africa’s lush habitats.
But they rarely prosper entirely indoors in a dark spot and discard flowering.
So, choose a bright indoor area with filtered sunlight (dappled east-facing or near a north-facing window) for quick blooming while growing Primrose in pots or containers.
Cape Primroses last only 6 months without adequate light before slacking and halting flower production indoors.
But with pruning and feeding, Cape Primrose will rejuvenate with the same vigor in the next growing seasons.
How to Care for Cape Primrose Indoors?
Stick to the following requirements to care for your Cape Primrose plant.
1. Light & Temperature
- Curtained-filtered light (all seasons) with 8 hours of daily darkness
- About 55-80°F surrounding temperature (avoid temperature drops below 55°F)
- Optional Artificial Lighting: About 8 inches beneath grow lights for 12-15 hours daily
2. Watering & Humidity
- Regular watering in spring and summer to moisten the top 1-2 inches of soil
- Avoid or decrease watering in fall and winter by checking the upper layer of potting mix
- Indoor Humidity: Around 50% (using a humidifier or humidity trays)
3. Soil & Fertilizer
- Humus-rich organic well-aerated potting soil (pH levels: 5.5-7.3)
- Fertilizer Application: Every 2-3 weeks in spring & summer
- Prevent fertilizer application in fall & winter
4. Pruning & Repotting
- Repotting: Every 1-4 years during early spring in a 0.5-1 inch wider and deeper terracotta pot when the plant doubles in size or becomes root bound
- Pruning: Occasional or early spring trimming to remove yellow, brown, or pest or disease-infested leaves using sterilized pruners
Problems of Indoor Cape Primroses [With Solutions]
Some common issues while growing Cape Primroses and their solutions are as follows.
1. Leggy Appearance & Slow Growth
- Low light
- Low fertilizer application
- Place your Cape Primrose near an indirect light source or below grow lights.
- You can also prune the lumbering stems or leaves and manage the light needs.
- However, situating the plant in direct sunlight for 1-2 hours a day can also solve this issue.
- Use nitrogen-based fertilizer to speed up their vegetative growth.
2. Less Flowering Tendencies
- Lack of pollinators
- Low light
- Pollinate indoor Cape Primrose flowers using Q-tips manually during their flowering spell (spring-summer).
3. Root Rot & Yellow or Brown Leaves
- Soggy soil
- Change the potting soil if it’s giving off a fishy smell, and remove the black mushy roots.
- Amend the soil with organic perlite, use porous pots, or add drainage holes in planters.
- Employ self-watering pots to hydrate the plants automatically.
