When does the cassia flower bloom?

Are you curious about when cassia trees bloom and some small gardening tips related to the flowering season of cassia? Please see the detailed introduction below.

There is less than a month left before cassia flowers begin to bloom. I remember from high school, every September and October, as soon as I stepped out of the classroom after class, I could smell the strong fragrance of flowers in the air, as if the whole world was filled with the scent of cassia, even though I couldn't see the cassia flowers, their fragrance floated in the air like a "living perfume."

The blooming period of cassia trees growing by the roadside is actually not long, usually lasting about 20 days before they start to wither. However, if you grow cassia trees yourself and take good care of them, it's possible for them to bloom for two months. The flowering season of cassia is approaching, so how should you care for them during the period before the flowering season?

I. Methods to make cassia trees bloom more

1. Master the unique watering method for cassia trees

I believe that watering cassia trees doesn't apply to the "dry-wet" or "thoroughly wet" methods, but needs to be mastered separately. In seasons like the current transition from summer to autumn, when the weather is relatively dry, more watering is needed. Keeping the soil slightly moist is fine, and using a spray bottle to water can prevent excessive watering and control the amount of water well.

If the weather is overcast or rainy, less watering is needed, and cassia trees that have been rained on should be drained in time to prevent issues with waterlogging in the potting soil. Cassia trees are easily drowned after the soil becomes waterlogged. Less watering should also be done when new shoots appear.

2. Different fertilizing frequencies at different times

Many long-term gardeners should know that cassia trees prefer animal manure, especially pig manure, so they are usually fertilized with decomposed pig manure liquid. The cassia trees I've seen are usually fertilized with decomposed cake fertilizer liquid.

Only by absorbing fertilizers will cassia trees produce more flowers with a stronger fragrance. It's mid-August now, and you can apply the last dose of fertilizer before the flowering season. Previously, it was fertilized every 10 days in spring and every week in summer.

3. Daily pruning management cannot be stopped

Cassia trees have a long lifespan and a well-developed root system. Generally, a mature cassia tree will have two stages of growing new branches each year. Pruning is especially important before the flowering season to ensure that the flowers are more vibrant and produce more full blooms.

The pruning method is the same as usual: cut off the old, weak, and withered branches, and do some thinning in dense growth areas. This allows for more even sunlight exposure. When pruning such thick branches like cassia, it's better to use professional gardening shears.
