Bacopa (Bacopa), or Sutera, is an ornamental plant with delicate leaves and abundant small blooms that has won the hearts of many gardeners thanks to its versatility and aesthetic appeal. In Ukraine, it is grown mostly as an annual crop, although in the southern regions and in container culture it can also be kept as a perennial. The plant forms cascading, trailing shoots up to 60 cm long, richly covered with small white, pink, lilac, or blue flowers. Bacopa is ideal for hanging planters, balcony boxes, flower beds, and as a filler in mixed plantings.
For Ukraine’s climate, bacopa is quite well adapted: it tolerates the hot southern summer well, while in the central and northern regions the warm periods of spring and summer are sufficient for full development. It performs best at temperatures of +20 to +25°C, but can withstand short-term fluctuations. The plant needs plenty of light, although it also tolerates light partial shade. It is important to note that a sunny location ensures abundant and continuous flowering from May to October. Under conditions of frequent rainfall or prolonged cloudy weather, bacopa flowers less vigorously and becomes leggy, losing its compact shape.
Among the main advantages of bacopa are:
long, continuous flowering until late autumn
high ornamental value even without flowers thanks to its lush foliage
resistance to drought and short-term drops in temperature
self-cleaning — faded flowers fall off on their own and do not need to be removed by hand
versatility in planting — it can be grown both in the ground and in containers
Bacopa is a light-loving plant. It develops best in open, well-lit areas. When grown in partial shade, flowering may weaken, shoots may stretch, and the plant’s decorative appeal may decrease. Southern or southeastern balconies, flower beds, and mixed borders are optimal. Open, windy places should be avoided, especially for hanging containers, because bacopa has delicate shoots that are easily damaged. In open ground, it is important to choose sites where water does not stagnate after rain.
Bacopa is not overly demanding about soil, but it grows best in light, well-drained, fertile substrates with a neutral or slightly acidic reaction (pH 6.0–6.5). If the soil is heavy or acidic, sand, peat, and humus should definitely be added. Before planting:
In open ground, the plot is dug to a depth of 20–25 cm, and compost or humus (5–6 kg/m²) and wood ash (100 g/m²) are added.
In pots or planters, a drainage layer of expanded clay or small pebbles (2–4 cm) is created, and the substrate used is either a ready-made mix for balcony flowers or a blend based on peat, sand, and coconut fiber.
Excess nitrogen should be avoided, since it stimulates leafy growth but weakens flowering.
It should also be taken into account that bacopa combines beautifully with other ornamental crops: petunia, verbena, lobelia, and calibrachoa. In mixed plantings, it is placed along the edges so the shoots can cascade downward nicely, creating a waterfall of flowers.
The most common method of propagating bacopa in Ukraine is by growing seedlings from seed. The seeds are very small, so they are not buried in the soil; instead, they are spread evenly over the moist surface of the substrate and lightly pressed in. To retain moisture, the sowing is covered with transparent film or glass. Sowing is carried out in February–March, since bacopa has a long development period. At a temperature of +20 to +24°C, seedlings appear in 10–14 days. As soon as 2–3 true leaves are formed, the seedlings are pricked out into individual cups or trays.
After the true leaves appear, the seedlings begin to be hardened off: the temperature is lowered, the room is ventilated, and the young plants are gradually exposed to sunlight. Planting in open ground or containers is done in May, once the threat of frost has passed. The recommended spacing is 20–25 cm between plants. Bacopa takes root quickly and within 2–3 weeks forms a dense green carpet.
An alternative method is cuttings. In August–September, cuttings 8–10 cm long can be taken, rooted in water or in a moist sand-and-peat substrate, and then kept over winter in a bright room at a temperature of +12 to +16°C. In spring, the resulting plants are planted in containers or in the ground. Cuttings are the best option for preserving varietal traits, since propagation by seed may result in variation in color and form.
Bacopa is a plant that responds well to regular care and quickly shows signs of mistakes. The main rule is moderation in everything: excessive watering leads to rot, while lack of water causes wilting and a halt in flowering. The best option is to maintain constant moderate soil moisture. In hot summer conditions, bacopa is watered daily, but in small portions and preferably in the morning or evening, without wetting the leaves.
For long-lasting and abundant flowering, feeding every 10–14 days with complex fertilizers for flowering plants is necessary. The best approach is to alternate mineral fertilizers with organic infusions (humates, biohumus). Excess nitrogen causes active green growth at the expense of flowering, so during budding and active flowering it is advisable to increase the content of phosphorus and potassium. The bush is shaped by pinching the tips of the shoots — this stimulates branching, improves air circulation, and enhances the overall appearance of the plant. Pinching is done every 3–4 weeks or as needed.
Bacopa is resistant to most diseases, but under unfavorable conditions (stagnant moisture, overcrowded planting, poor ventilation) it may suffer from fungal diseases and insect attacks. The most common problems are powdery mildew, root rot, aphids, and spider mites. For prevention, plants should be inspected regularly, especially during rainy periods or when grown in a greenhouse.
The most common diseases:
Powdery mildew — a white coating on the leaves that spreads quickly. Treatment: Topaz, Skor, or folk remedies such as garlic infusion and whey.
Root rot — caused by excessive watering and stagnant water. Prevention: a light substrate and good drainage. Treatment: Fitosporin, Trichoderma.
Chlorosis — yellowing of the leaves caused by iron deficiency or poor aeration. Solution: foliar micronutrient fertilizers and loosening the soil.
Pests:
Aphids — suck sap from the leaves and cause them to curl. Soap solution, Fitoverm, and Inta-Vir are used.
Spider mite — appears in high temperatures and low humidity. It can be recognized by a fine web and yellow spots. Remedies: Actellik, Vertimec.
Whitefly — small flying pests that are especially active indoors. Treatment: yellow sticky traps, Biotlin, Aktara.
One of bacopa’s advantages is its ability to self-clean continuously: faded flowers fall off on their own, do not spoil the plant’s appearance, and do not need to be removed by hand. However, to preserve its ornamental value until autumn, it is important not to forget regular pinching of the shoots, removing yellowed leaves, and feeding. Weak branches that thicken the planting should also be removed in time.
In most regions of Ukraine, bacopa is grown as an annual, but if desired it can be kept through winter. To do this, at the end of September or in October it is transplanted into a container, moved to a bright room with a temperature of +12 to +16°C, watering is reduced, and feeding is gradually stopped. In spring, cuttings can be rooted, or you can wait for active regrowth and plant it out again in a flower bed or planter.
In landscape design, bacopa is extremely versatile:
in hanging planters — it creates a waterfall of greenery and flowers
in flower beds — as a border or groundcover plant
on balconies — paired with petunia, lobelia, and surfinia
in mixed borders — combined with verbena, calendula, and lavender
This is an ideal plant for creating soft, cascading forms and a cozy floral setting. It does not require excessive care, yet rewards generously with long-lasting flowering.
