Guide To Rudbeckia Deadheading – How To Deadhead Black Eyed Susans

It’s an age old tale in the garden, you planted one cute little Black Eyed Susan in a perfect spot. Then a couple seasons later, you have hundreds of little ones popping up everywhere. This can be maddening for the tidy, organized gardener. Read more to learn how to deadhead Black Eyed Susans for control, as well as the pros and cons of cutting blooms on Rudbeckia plants.

Do You Deadhead Black Eyed Susans?

Deadheading Black Eyed Susan flowers is not necessary but can prolong the blooming period and prevent the plants from seeding all over your landscape. There are about twenty-five native species of Rudbeckia blanketing fields and meadows across North America.

In nature, they efficiently go about their business of providing food and shelter for butterflies, other insects, birds and small animals while self-sowing new generations of Black Eyed Susan plants.

Left to grow wild, Rudbeckias are visited throughout the blooming season by pollinators and butterflies like fritillaries, checkerspots and swallowtails. In fact, Silver checkerspot butterflies use Rudbeckia laciniata as a host plant.

After the blooms fade, the flowers turn to seed, which goldfinches, chickadees, nuthatches and other birds feed on throughout the fall and winter. Colonies of Black Eyed Susans also provide shelter for beneficial insects, small animals and birds.

Cutting Blooms on Rudbeckia

While wildflower gardens are great little habitats for birds, butterflies and bugs, you don’t always want all that wildlife right next to your front door or patio. Black Eyed Susan can add beautiful and durable splashes of yellow to the landscape, but their seed will happily sow itself everywhere if not deadheaded.

Cut off faded and wilted Black Eyed Susan blooms throughout the growing season to keep the plant tidy and in control. Rudbeckia deadheading is easy:

On Rudbeckia that grow a single flower on each stem, cut the stem back to the base of the plant.
For Rudbeckias with multiple flowers on a stem, just snip off the spent blooms.

In autumn, cut Black Eyed Susan back to about 4” tall or, if you wouldn’t mind a few more Black Eyed Susan plants, let the last blooms go to seed for the birds. The seed heads can also be cut and dried to propagate new plants.

Description:

1999 Perennial Plant of the Year; Bright golden yellow daisies with dark cone centers have long lasting bloom

Ornamental Features

Goldsturm Black Eyed Susan has masses of beautiful gold daisy flowers with dark brown eyes at the ends of the stems from mid summer to early fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its serrated pointy leaves remain dark green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Goldsturm Black Eyed Susan is an herbaceous perennial with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Goldsturm Black Eyed Susan is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Container Planting

Planting & Growing

Goldsturm Black Eyed Susan will grow to be about 24 inches tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 15 years.

This plant should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn’t be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selection of a native North American species. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Goldsturm Black Eyed Susan is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a ‘thriller’ in the ‘spiller-thriller-filler’ container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.

Rudbeckia, Black-eyed Susan, Coneflower

Rudbeckias have become one of our most popular garden plants in recent years, and it’s not surprising – bushy plants produce masses of colourful flowers with a long flowering period from July to October.

Rudbeckias are characterised by their colourful daisy-like flowers surrounding a prominent conical disk. They can be annuals, biennials or herbaceous perennials, the annuals grown as half-hardy annuals, sown indoors in warmth. The annual varieties may survive from year to year if left in the garden, but flowering may be reduced in subsequent years.

Although yellow is the prominent colour, in recent years numerous red and orange-flowered varieties have been produced.

How to grow rudbeckias

Cultivation

Rudbeckias grow perfectly in positions in either full sun or light shade. They need a fertile soil enriched with lots of organic matter, which holds plenty of moisture in spring and summer, doesn’t dry out or become waterlogged.

Sowing rudbeckias

Sow seeds from February to April in pots or trays of moist seed sowing compost at a temperature of 20-25C (68-77F).

Transplant seedlings when large enough to handle into 7.5-10cm (3-4in) pots. Harden off by growing on in cooler conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart.

Sow seeds from February to July in trays or pots of good seed compost at a temperature of 65-70F (18-20C).

Transplant seedlings when large enough to handle into 7.5-10cm (3-4in) pots. Harden off early-sown plants by growing on in cooler conditions for 10-15 days before planting out after all risk of frost, 60-90cm (2-3ft) apart.

Planting rudbeckias

You can buy young plants from garden centres, nurseries or mail order suppliers. Perennial varieties can be planted at any time of year, although autumn or spring are the best times.

Dig over the planting area, incorporating lots of organic matter such as compost, especially if the soil is heavy clay or light, well-drained sandy soil. Dig a good sized hole big enough to easily accommodate the rootball.

Place the rootball in the planting hole and adjust the planting depth so that the crown of leaves is at soil level. Mix in more organic matter with the excavated soil and fill in the planting hole. Apply a general granular plant food over the soil around the plants and water in well. Then add a 5-7.5cm (2-3in) thick mulch of organic matter over the soil around the plants.

Suggested planting locations and garden types

Flower borders and beds, patios, containers, city and courtyard gardens, cottage and informal gardens, cut flower garden.

How to care for rudbeckias

Water plants whenever necessary to keep the soil or compost moist during spring, summer and early autumn, as this will prolong flowering. Always try to water the soil or compost, rather than over the foliage.

Apply a liquid plant food every couple of weeks in the growing season to encourage more, bigger and better flowers.

Deadhead faded flowers regularly to encourage more blooms to be produced.

Apply a granular general plant food around the plants in spring.

Apply a layer of compost or mulch around the plants in spring to retain soil moisture and control weeds.

Water plants whenever necessary to keep the soil or compost moist during spring, summer and early autumn, as this will prolong flowering. Always try to water the soil or compost, rather than over the foliage.

Feeding with a liquid plant food every couple of weeks in the growing season will also encourage more, bigger and better flowers.

Plants are compact and bushy and rarely need staking.

Wherever possible, deadhead plants by cutting back faded flowers to encourage further flushes of flowers. In autumn, cut down all growth to ground level after it has died back.

Divide overcrowded plants every 3 to 4 years as new growth begins in spring, lifting the plants and dividing them into smaller clumps.
