This section will specifically focus on growing Bidens flowers in the garden or lawn, i.e., outdoor.

Best Time to Grow

The foremost thing to consider before planting Bidens is the most suitable time to plant them.

The answer to this query is in spring. Since, Bidens plant will die once the temperature starts falling in the winter months, if you plant it in spring, it will get sufficient time to give your the flowers.

However, if winter in your area is relatively milder or moderate, you can also plan Bidens in the fall.

Here, you must note that Bidens are frost-sensitive, which means they will die if the temperature goes beyond 40°F or 5°C. So, to be precise, grow these plants as you would grow any annual flowering plant variety.


After deciding on the month, now it’s time to choose the ideal location.

Bidens flowers love to get soaked in sunlight and grow in any area that receives partial to full daylight. Therefore, the ideal place to plant your Bidens would be somewhere that gets 4- 6 hours of direct sun per day.

So what if you want to grow these plants indoors? Well, try to keep them in spots that receive at least partial daylight, as the windowpane. Although Bidens plants can survive in the shade, they will procure fewer flowers in such situations.


The soil requirement for these plants is moist and well-drained. Make sure that your chosen area does not allow water to clog. A consistent soggy soil may cause root rotting. In addition, these plants produce abundant blossoms if planted in solid rich in nutrients.

As far as the acidic level is concerned, Biden plants can tolerate neutral to slightly acidic soil.

Sun Exposure

We have already suggested planting these annual plants in an area that receives good sun exposure- around 4- 6 hours daily.


One of the best things about Bidens plants is that they are drought resistant, which means once they are established, they won’t demand a high level of watering. However, you should not let the soil dry out completely if you want your plants to produce lovely and colorful blooms.


The ideal spacing between two plants is 12 to 16 inches.

  • Break the soil in the area where you want to plant your Bidens.
  • Amend the soil by mixing it with organic matter such as manure, peat moss, or garden compost. Make sure to loosen up the ground for better compost permeation.
  • You can also add a granulated starter fertilizer or a balanced all-purpose feed to give an extra boost to your plant’s growth.
  • Depending on the number of plants you want to grow, manage the spacing. You can refer to the above section to learn more.

(Note: Overcrowded Plants may lead to fewer blooms, and the growth may also get retarded as they compete for light.)

  • Remove and transplant the seedlings or the stem cuttings from their initial pots or containers to the amended soil.
  • However, before planting the seedlings, dig a hole in the ground twice the size of the root ball and deep enough for the plant to be at the same level in the background.
  • Place the root inside the hole and fill it with soil.
  • Make sure to even out the leveling soil.
  • Water the newly transplanted seedlings regularly for a couple of weeks to help them get established.

Growing Bidens Plants in Containers

If you want, you can grow Bidens indoors as well, and as we stated, these plants make excellent hanging flower baskets.

If you plan to grow Biden plants from seeds, it is advisable to sow the seeds by the end of May and keep your pot in a warm spot where it maintains room temperature. Since your plant won’t tolerate a chill environment, you can keep the container in a place with access to a room heater during the winter months.

It is important to note that the size of your container would decide the number of plants you can plant in it. For instance,

  • 4-inch pot- 1 plant
  • 6-inch pot- 2 plants
  • 10-inch pot- 3- 4 plants

Also, remember to fertilize your container plant more frequently than do the outdoor one. It is essential as a rich and nutritious soil is crucial for Bidens flowers to bloom.

Bidens Propagation

Bidens plants can be propagated through seeds as well as stem cuttings.

Propagating by Seeds

Bidens seeds tend to be dark brown, curved, and sticky, and if you go close to these plants, they may get stuck to your clothes.

If you want to propagate these plants by seeds, allow them to dry on the plant before harvesting. After collecting the dry seeds, you can sow them directly in a potting tray. Make sure to sow the seeds shallowly in moist and rich potting soil. Also, try to maintain a temperature of 66°F or 19°C to encourage sprouting.

It will take around 1- 3 weeks for the seeds to germinate, and once they start to grow leaves, you can transplant them to the final spot.

However, wait until the last frost date is over if you plan to sow the seed directly in the outdoor location. Doing so is essential, as Bidens seeds require a warm weather condition to grow.

Propagating by Stem Cuttings

You can also propagate Bidens plants by stem cuttings, apart from the seeds. You would need a stem cutting of 2- 6 inches to do this. Here, you must ensure to cut the stem from branch tips that do not have any flowers or seeds.

Dipping the stem in the rooting hormone is optional, although it may result in better growth. It would take somewhere around 3- 6 weeks for the cutting to root. Afterward, you can plant it in moist, nutrient-rich potting soil and water it frequently.
