Waller's balsam - from seeds and seedlings

Thanks to its undoubted advantages - high decorative qualities, versatility of use and unpretentiousness - Waller's balsam has found wide application for the production of pottery products and containers. Modern hybrids are compact, do not stretch even with fluctuations in temperature and humidity, which makes it possible to increase the yield from 1 m² when growing seedlings. In addition, the seeds of these hybrids have high (up to 95%) and simultaneous germination.

F1 Campos Elite Mix - special mixtures of early and abundantly flowering, well-branched balsams

Due to the huge variety of flower colors and the ability to grow both in the shade and in the sun, Waller's Balsam (Impatiens walleriana syn holstii, sultani) "Classic" plant for hanging baskets. In a flower garden and container, it is relatively resistant to hot, dry weather. Varieties and hybrids with double flowers, propagated both by seeds and cuttings, are especially attractive to buyers.

Varieties and hybrids

Seed hybrids vary in height, bush shape, flower size and shape, and in relation to light. There are hybrids that grow well in bright sun, as well as more shade-tolerant and intermediate ones. In catalogs, seed propagation hybrids are most often divided into non-double and double. Hybrids with strongly double flowers, as well as non-double flowers with an ampelous stem, are propagated vegetatively.

Modern technology for growing seedlings from seeds


Sowing of tall hybrids intended for large hanging baskets begins in late March - early April. In April, sowing hybrids for pots and containers. And at the end of April, you can sow early flowering hybrids for cassettes, which are supposed to be planted in flower beds.

To obtain compact, fast and abundant flowering seedlings, it is necessary to maintain a balanced substrate moisture and avoid temperature fluctuations. Medium-sized balsam seeds: 1 g –1 250–2000 pcs. With a high germination capacity of most heterotic hybrids, 1,100–1,200 plants are required to obtain 1,000 plants. seeds. The highest germination rate is with specially prepared seeds (primed). In addition, the seedlings obtained from them bloom faster.

Seeding cassettes with 512 cells and larger are used for seeding. The substrate for balsam should be almost neutral (pH 6.2–6.5) - at higher acidity, the yield of seedlings decreases due to their death after germination. The moisture content of the substrate during sowing is very high, the humidity of the air is about 100%. Seeds are lightly sprinkled with vermiculite or left open (in germination chambers), because low illumination (100–1,000 lux) promotes germination.

For friendly germination of seeds, it is necessary to maintain a temperature of 22 ... 24 ° С. At temperatures above 25 ° C, germination stops, and at temperatures below 21 ° C, the speed and uniformity of emergence of seedlings decreases. Temperatures below 18 ° C can cause death of the primary root and deformation of the 1st leaf.

Under optimal conditions, seedlings appear in 3-5 days. After that, the moisture content of the substrate is gradually reduced: on the 3rd-7th day - to a very wet state; on the 4-10th day - to moderately wet; after the 11th day and until the cotyledons are fully deployed - to slightly moist. With the help of ventilation, the air humidity is maintained at 40–70%.

Seedling care

The optimum temperature for seedlings remains the same as for germination - 22 ... 24 ° C, while it is important not to allow it to fluctuate. At temperatures below 18 ° C, in combination with the high humidity of the substrate, the roots of the seedlings rot and the leaves turn yellow. Watering in the second half of the day is especially unacceptable. the moisture remaining on the seedlings promotes rotting of the stems, and the presence of roots in water for 4 hours leads to their death. Illumination at this stage should be 20,000 lux.

After unfolding the cotyledons, seedlings are fed with calcium nitrate (14: 0: 14) at a weak concentration of 0.0025–0.0035% (25–35 ppm in nitrogen). Phosphorus in top dressing during this period is not needed - its excess can cause the seedlings to be pulled out.

After the appearance of the 1st true leaf, it is still important to maintain a balanced moisture content sufficient for growth. Seedlings are watered abundantly only when the moisture content of the substrate becomes low, while avoiding prolonged and strong drying (until wilting), because this causes yellowing of the leaves. The temperature at this stage is slightly reduced (to 20 ... 22 ° C), the illumination is left at the same level, but in the bright sun the seedlings shade, especially hybrids intended for shady places.

After the appearance of the first true leaf, seedlings are rarely fed so that they remain compact, alternating irrigation with clean water with irrigation with fertilizers with potassium or calcium nitrate (14: 0: 14) at a concentration of 0.0075-0.011% (75-110 ppm in nitrogen ).

Transfer in a container

With the appearance of 2-3 true leaves, the seedlings are prepared for transplantation: they maintain temperature, light and humidity conditions, as in the previous stage. The main requirement during this period is not to overfeed the seedlings, because with an excess of nitrogen, they stretch, and with a large amount of potassium, the leaf blade twists.

In total, seedlings are kept in seed cassettes for 4–6 weeks. Depending on the purpose of the seedlings, they are planted in containers or cassettes. In these containers, the substrate (pH 6.2–6.5) should not be excessively moist. Air temperature - from 21 ... 24 ° С during the day to 16 ... 18 ° С at night. The lighting is not intense (rather partial shade), but for hybrids intended for open places, more light is required, otherwise, after planting in open ground, burns may appear on their leaves.

During this period, top dressing is minimal: about 2–3 times with complex fertilizers (13: 2: 13 [6Ca: 3Mg]) at a concentration of 0.0075–0.01% (75–100 ppm in nitrogen).

If the moisture content of the substrate and the concentration of fertilizing were optimal, then you can get compact and abundantly flowering plants without the use of growth substances.

The seedlings are ready for sale, depending on the hybrid:

  • in small pots or cassettes - after 7-9 weeks;
  • in 10 cm pots - after 8-11 weeks;
  • in hanging baskets - after 10-12 weeks.

Modern technology of growing from rooted cuttings

Diadem Pink - optimal in containers

Cultivars and hybrids from cuttings are heterogeneous in their heat and light requirements. Terry varieties are more light and thermophilic than non-double varieties. The latter are more often planted in hanging baskets and in partial shade, because there are seed hybrids for sunny places.

The cuttings are planted in a moist (not excessively) substrate with a pH of 6.2–6.5. The first 2 weeks the plants are watered moderately (with an excess of water, they stretch out and bloom weaker), but not allowing the soil to dry out. When they grow, they are slightly dried to speed up flowering and shorten internodes.

For terry hybrids, the illumination should be 40,000-60,000 lux - if it is less than 30,000 lux, the plants will stretch. At high temperatures, all balsams must be shaded so that there are no burns to flowers and leaves. For double hybrids, it is recommended to maintain a temperature of 21 ... 24 ° С during the day and 18 ... 21 ° С at night. Non-double hybrids can be grown at lower temperatures - 16 ... 18 ° C.

As with seedlings, cuttings must not be high in salt. Plants are fed with high (175–225 ppm in nitrogen) concentrations of complex fertilizers with a low content of phosphorus and ammonium (they enhance vegetative growth to the detriment of flowering). If the seedlings do not have enough nutrition, then the plants are obtained with thin stems and poorly branching.

Plants from cuttings bloom rather quickly and, subject to optimal conditions of temperature and humidity, do not need to be pinched. To avoid pulling the stems out (especially in low-light greenhouses), arrange the plants so that they do not come into contact with the leaves.

When growing Waller's balsams for the prevention of powdery mildew and root rot:

  • planting should not be thickened;
  • you can not overfeed plants with nitrogen;
  • you can not make abundant watering, especially at low temperatures;
  • in case of prolonged rains, preventive spraying with fungicides should be carried out.
