Fall just isn’t fall without chrysanthemums—just look at any porch or terrace decked out with those big, round bushes, and you instantly feel the season’s cozy vibe. But potted chrysanthemums have different needs than those grown in the garden, and that’s important to know.
If you want your balcony or patio to burst with colorful autumn blooms, here are four easy tips to keep your potted chrysanthemums flowering longer.
1. Pick a Healthy Plant
Here’s the secret: buy as early as you can, because the best plants get snapped up fast. Wait too long, and you’ll be left choosing from browning, wilting flowers.
Also, don’t grab the fullest, most colorful blooms right off the shelf! They might look tempting, but those plants are nearing the end of their flowering. Instead, choose one packed with closed buds—these will open beautifully once you bring them home.
2. Choose the Right Variety
Not all chrysanthemums are the same when it comes to bloom length and timing. For a perennial beauty, look for garden chrysanthemums (perennial multiflora). These show off rich, jewel-toned colors from September through mid-October. They’re often pruned in summer to avoid early blooming, then put on their autumn show. Bonus: they can overwinter in pots in a garage or shed.
The other option is the florist type, usually bought for just one fall season. These bloom once but spectacularly, for about eight weeks in September and October, then fade away. They can’t be overwintered, so think of them as seasonal, “annual” decorations.
3. Give Them Plenty of Sun and Water
Chrysanthemums love sunlight and need at least six hours a day. If they’re kept in shade, they can grow leggy and won’t produce those lush, colorful blooms.
The only exception is in hot climates above 30 °C (86 °F), where it’s best to avoid the harsh afternoon sun. But come fall, when most people plant them, this usually isn’t an issue.
Along with sunlight, water is key. The soil should never dry out completely—especially in pots without deep soil to draw moisture from. Keep an eye on the soil surface and leaves: if they droop or the soil feels dry, it’s time to water.
Bonus tip: You can even overwinter your chrysanthemum. When the first frost hits, stop trying to keep it blooming. Cut back the wilted flowers but keep the stems, then move the plant to a frost-free spot. Cover the soil with mulch and wrap the pot with a blanket or cloth. It’ll sprout fresh growth in spring.
4. Regularly Pinch Off Faded Flowers
To keep your chrysanthemum blooming continuously, it’s important to remove spent flowers. As soon as a bloom starts browning or wilting, snip it off with sharp scissors just below the petals. This way, the plant saves energy for new buds instead of the fading parts.
