In this comprehensive guide, we will cover everything you need to know to nurture happy, healthy Ascot rainbow spurge plants indoors and enjoy their vibrant colors and textures all year round
Providing Optimal Growing Conditions
Ascot rainbow spurge thrives best with
-
Bright Light: At least 4-6 hours of direct sunlight daily. South or west-facing windows are ideal. Supplement with grow lights.
-
Warm Temperatures: Average room temps of 65-75°F during the day and above 55°F at night. Avoid drafty areas.
-
Good Air Circulation: Use fans to circulate air and prevent disease. Avoid stale, humid conditions.
-
Well-draining Soil: Use a general potting mix amended with perlite or pumice for drainage.
-
Moderate Water: Water when the top inch of soil is dry. Avoid excess moisture.
-
Average Humidity: 40-60% humidity is ideal. Use a humidifier or pebble tray if dry indoor air is an issue.
Closely mimicking these natural growing conditions will set your Ascot rainbow spurge up for success indoors. Pay close attention to providing sufficient light.
Choosing the Right Pot or Planter
Use a container with drainage holes at least 2-3 inches wider than the spurge’s root ball. Shallow pots work better than deep containers. Terra cotta, plastic, ceramic, and self-watering pots are suitable choices. Make sure the planter is proportional to the plant’s size.
Using the Proper Potting Mix
A lightweight, well-aerated potting mix is critical for healthy spurge roots and good drainage. Pre-made cactus and citrus mixes work well. You can make your own by combining:
- 2 parts peat moss or coco coir
- 1 part perlite or pumice
- 1 part compost
Adjust amounts as needed to create a loose, fluffy texture.
Caring for Your Ascot Rainbow Spurge
-
Water thoroughly whenever the top 1-2 inches of soil become dry. Avoid wet feet.
-
Fertilize monthly in spring and summer with a balanced liquid fertilizer diluted to half strength.
-
Prune overgrown shoots and pinched-back tips to encourage fullness.
-
Clean leaves regularly with a damp cloth to prevent pests and improve light exposure.
-
Monitor for common issues like aphids, mealybugs, leaf spot, and root rot. Treat promptly.
-
Propagate new spurge plants from cuttings to expand your indoor collection.
With the right care, your Ascot rainbow spurge will thrive indoors for years of enjoyment. Its versatility also makes it easy to move outdoors for the summer.
