As a gardener, one of the most frustrating sights is a coleus plant that seems stuck; its leaves just aren’t getting any larger no matter how much time passes. If this sounds familiar, don’t lose hope yet!
Chances are, a simple fix can get your coleus growing vigorously again. Here are some of the most common reasons why a coleus may be stalled and what you can do about it.
Coleus Plant Not Growing? Common Issues and Solutions
Common reasons why your Coleus plant isn’t growing are not enough sunlight, lack of nutrients, poor soil quality and drainage, or pests or diseases.
So, now that we have answered the main question, let’s dive into more detail.
Insufficient Light:
Coleus thrives in bright, indirect light and needs a minimum of 4-6 hours of sunlight per day. If yours is in a shady spot, it won’t grow well. Move it to a sunnier location and increase light levels gradually to avoid sun scorching.
Lack of fertilizer:
Coleus are heavy feeders and need regular nutrients to fuel their growth. I fertilize mine monthly in spring and summer with a balanced liquid plant food. Make sure yours is getting fed too.
Poor Drainage:
Coleus doesn’t like soggy soil, which can cause root rot. Ensure your container has drainage holes and the soil dries out between waterings. Use a well-draining potting mix to encourage robust roots.
Pests or diseases:
Check closely for signs of infestation, like aphids, spider mites, or fungal spots on leaves. Treat any issues promptly according to recommended products or methods. Healthy plants grow best.
Cold Temperatures:
Coleus can tolerate light frosts but won’t thrive in temperatures below 50°F. Bring yours indoors before nighttime lows drop too much.
Final Thoughts
With some tweaks to light, watering, nutrients, or location as needed, your coleus should start actively growing again within a couple weeks. Let me know if you have any other plant questions!
