In this article, we will discuss how to grow Bidens in containers. You can say that this tender perennial is one of the easiest bedding plants to grow. It is a prolific growing plant with honey-scented, yellow blooms. Bidens is part of the Aster family and 200 species are found in South America and Europe. It occurs naturally in America, where you often can see wild species growing at the side of roads. They are famous for the tiny-sticky seeds that cling to clothing.
Traditionally the older varieties produce yellow or orange blooms, but newer varieties can come in pink, golden yellow or white.
In countries that get no frosts, the plant is a perennial, but in other countries, it is treated as an annual.
HOW TO GROW BIDENS IN CONTAINERS
You can either grow them from seeds or you can find them as garden-ready plants for planting directly in gardens.
HOW TO GROW FROM SEEDS
First, fill a seed tray with seed compost between February to April. Water it well and sprinkle the seeds thinly over the top surface of the compost. Sieve a thin layer of seed compost on top of the seeds and place a propagator lid on top of the tray. Place it in a warm windowsill and after 20 days the seeds should start to germinate.
Once the seedlings are big enough to handle prick them out and transfer them to individual 7.5cm pots full of multipurpose compost. Continue to grow on and from late May to early June, you can harden the plant off before planting them in containers outside.
PLANTING CONTAINER-GROWN SPECIMENS
First, choose a container that is within character and size for the plants in question. Make sure it has plenty of drainage holes at the bottom and then add a 1cm layer of gravel to aid drainage. Fill it with a good quality multipurpose compost and dig a hole slightly bigger than the root ball it came in the original container.
Place the plant in at the same level it came in the original pot-no shallower and no certainly no deeper. Backfill the plant with the growing media, making sure that any gaps that remain are filled with more compost. Firm the plant in and water well.
You can grow them as a specimen plant but they can also be combined with Verbenas, Surfinias, Petunias or garden Helichrysum.
Place them in the brightest location possible where the blooms will be their best. They need at least 4 hours of sunlight a day. Without adequate light, they will grow very leggy and this will spoil the look. This is why it may need to be cut back to keep it compact and productive.
It will need to be watered when 5cm below the top of the surface of the compost feels dry when you stick your finger in. It Will wilt in prolonged drought but will soon recover once it is watered again.
It is best to feed weekly with a high potash liquid fertilizer at the manufacturer’s recommendation to get the plant to bloom for long periods. More fertilizer means more blooms but not too much as you can kill it with too much kindness.
You will also need to deadhead regular, along with regular trimming will keep the plant productive, in terms of flowers and also will keep it neat and tidy.
PESTS AND DISEASES
The good news is that the plant does not suffer readily from pest attacks it diseases that can ruin the plant, Overwatering can lead to root rot and this is why drainage is very important.
