Significant care of Gorgeous Black-eyed Susan flower(USA)

Black-eyed Susan is a wildflower that grows on vine plants. It has various varieties according to climate. Some of them are annual and perennial, and some of them are biennial. 

Black-eyed Susan flowers look very attractive when they bloom. The name is suitable because there is a black-eyed part at the center of the golden-yellow petals of these flowers. 

Black-eyed Susan vine flower care

Although it is a very low-maintenance plant but needs some specific care at certain growing stages. I have these plants in my garden so I can say surely that you need some maintenance not regularly but when required. 

Black eyed Susan care

Before giving you the details, I want to give you some brief on its identification, season, and ideal growing conditions so that you can figure out the plant's needs and the efforts required. 

Identification of black-eyed Susan

  • Plant type- Perennial, biennial, and annual
  • Flowers- Dark yellow, golden with a black button center
  • Color- Golden, yellow petals, blackish green leaves 
  • Size- 4 to 5 feet tall

Season of growing 

The best time for such plants to grow and propagate is the season when they can get time to develop roots and establish growth.

Early spring to late spring and early fall to mid fall is a good time to grow black-eyed Susan. They get further time to develop seeds in such conditions. 

But still, in warm regions, you can go with either of the seasons but in cool climates, you should sow and propagate black-eyed Susan in spring. 

Conditions of growing Black-eyed Susan

  • Soil type

No specific soil is required for Black-eyed Susan. These flowers can grow best in every kind of soil that has light components with a well-drained structure. Soil pH remains 6.6 to 6.9 while we grow black-eyed Susan. If the soil is less fertile or non-agricultural, you can add moisture and compost to it to improve the soil. 

  • Climate conditions

It can grow in almost every climate(except too cold). You can't propagate it in snowfall regions or too-hot regions. It generally grows in cool-warm weather where the temperature range from a minimum of 20F to 70F maximum. 

The overcast conditions are good at the time of propagation but not when flowers bloom. 

  • Sunlight and shade

One of the key factors in growing Black eyed susan flowers in your garden is sunlight. Full sunlight in moderate climate conditions is too good for flower bloom. If sunlight is absent or very low intensity, then it is not good for these black-eyed Susan flowers for too long. Don't let them be in shady areas when flowers start blooming. 

Care of black-eyed Susan

  • Irrigation

It can't tolerate too dry conditions or too wet conditions when humidity is too high. It is good to irrigate them once a week when the flowers are not blooming. In summer, you can shorten the time of irrigation to twice a week. In winter, don't wet the soil regularly. 

  • Fertilization

Fertilizing the Black-eyed Susan plants goes well till you fertilize them from time to time. Twice or three times a year is good enough to fertilize the black-eyed Susan vines. Some of them are biennial so they bloom only for the next year. Use either vermicompost or cow dung manure for fertilization in black-eyed Susan vines. 

  • Reseeding

When black-eyed Susan seeds become mature, they fall. After that, plants get to die. Some of them live for a couple of more seasons but they die ultimately. 

You can use these fallen seeds once more to reseed the black-eyed Susan vines once again. For that, fertilize your area first and make it moist. Don't use the seeds quickly after collecting them. Use them wisely and treat them before seeding. 

Other varieties of black-eyed Susan

Yes. There are several varieties of black-eyed Susan flower vines in the world that grows according to climate conditions. Some of them are annual, some perennial, and even some are biennial(that grow for two years)-

  • Rudbeckia fulgida
  • Cutleaf coneflower
  • Brown eyed Susan
  • Rudbeckia maxima
  • Californica
  • Alpicola
  • Occidentali

Few problems with black-eyed Susan

  • Mildew

White powdery mildew is very common on the leaves of black-eyed Susan when humidity is too high. It gets white fur on the leaves that sign the overmoisture and high humidity than required. To improve that, you can simply make drainage in the soil or try to cover them in a greenhouse if the conditions are not too good. 

  • Attract bees

It attracts bees to these flowers so it is not good to continuously go near the plants. Even if you do so, they may don't bite you but it is still risky. Before blooming flowers, there is no problem going near the plants but after flower blooming, don't risk too much to go near them or wear a safety kit first.
