Beautiful Plants For Your Interior
There’s something magical about watching your garden burst with color just as summer fades. The 🌼 Chrysanthemum steps in as the star of the show when most other blooms have called it quits.
But timing is everything with these beauties. Depending on the variety and your care, they can transform your space from late summer through fall.
Let me walk you through how to align their blooming with your garden goals and keep the color coming when you need it most.
Mum Blooming Seasons by Variety: Garden vs Florist Types
I’ve found that garden mums and florist mums follow completely different blooming schedules. This distinction is key for planning your garden’s fall color display.
Garden mums are the hardy perennials that return each year, typically bursting into bloom from late summer through fall. They’re built for outdoor conditions.
Garden vs Florist Mums: Blooming Timeline
| Variety | Blooming Season | Hardiness | Typical Use |
|---|---|---|---|
| Garden Mums | Late Summer – Fall | Perennial (Zones 5-9) | Outdoor gardens |
| Florist Mums | Year-round (forced) | Annual | Holiday gifts, indoor decor |
| Early Mums | August – September | Perennial | Early fall color |
| Late Mums | October – November | Perennial | Late fall displays |
On the other hand, florist mums are treated as annuals and are often forced to bloom for specific holidays like Mother’s Day or Easter. These won’t survive winter outdoors.
For early bloomers, I recommend varieties like ‘Sheffield Pink’ or ‘Clara Curtis’, which start flowering in August. These are perfect for bridging the gap between summer and fall.
Mid-season mums like ‘Emperor of China’ or ‘Ruby Mound’ typically bloom from September to October, providing that classic autumn color we all love.
Late-blooming varieties such as ‘White Butterfly’ or ‘Bronze Elegance’ hold off until October or November, extending your garden’s color well into the cooler months.
I’ve noticed that climate plays a huge role in blooming times. In warmer zones (7-9), mums may bloom earlier, while in cooler zones (4-6), the same variety might bloom later.
For the longest display, I mix early, mid, and late varieties in my garden. This creates a staggered blooming effect that keeps color coming from August through November.
Remember that day length triggers blooming in mums. They’re short-day plants, meaning they’ll only flower when days get shorter in late summer and fall. ☀️
How to Extend or Delay Mum Blooms in Your Garden
I’ve discovered that with a few simple techniques, you can control when your mums bloom to fit your garden’s needs. Whether you want color earlier or later, these methods work reliably.
One of my favorite tricks is pinching back the stems in early summer. This encourages bushier growth and can delay blooming by 2-4 weeks if done consistently.
Ways to Control Mum Blooming Times
- Pinch stems in June for bushier plants and delayed blooms
- Use blackout cloth to mimic shorter days and force early blooming
- Plant in containers to move and adjust light exposure
- Choose early/late varieties for natural staggered blooming
- Fertilize with phosphorus to boost flower production
For early blooms, I cover my mums with blackout cloth for 12-14 hours daily starting in mid-summer. This tricks them into thinking days are shorter.
If you want later blooms, keep them in bright light longer each day. I’ve had success with grow lights in a garage to extend their light exposure.
Container growing offers the most control. I can move my potted mums to lighter or darker spots as needed to manipulate their blooming schedule.
Remember that consistent watering and proper fertilization support these efforts. I use a balanced 10-10-10 fertilizer until buds form, then switch to low-nitrogen to focus on blooms. 🌼
