Daisy Polaris

You can plant 'Polaris' Daisy seedlings outdoors preferably from mid-May, when there is no longer a risk of ground frosts (after the 'Ice Saints'). If you have the option to protect the seedling with non-woven fabric or if the spring is mild, planting is possible even earlier (April). It is important that the soil is not frozen. Autumn planting is also possible (until the end of September) so that the plant manages to root before winter.

The Daisy is the queen of country and "cottage" gardens. It looks great in combination with:

• Oriental poppies (Papaver orientale)
• Bellflowers (Campanula)
• Sage (Salvia nemorosa)
• Larkspur (Delphinium)
• Rudbeckias (Rudbeckia)

This combination ensures successive flowering and a beautiful contrast of shapes and colors.

The biggest enemy is slugs, especially for freshly sprouting spring shoots. They can destroy the plant overnight.

• Protection: Use barriers against slugs, organic pellets (ferramol), or hand picking.
• The second common problem is aphids on stems and buds. If the infestation is severe, use a soap solution or a suitable insecticide.

The Daisy (Leucanthemum) is not considered a highly toxic plant. It is generally safe for gardens with children and pets. However, ingestion of a large amount of plant matter can cause mild digestive issues in sensitive animals (dogs, cats). In sensitive persons, contact with leaves may cause mild skin irritation (contact dermatitis), so gloves are recommended when handling.

The 'Polaris' Daisy likes soil that is not too dry, but cannot tolerate permanent waterlogging.

• After planting: Water regularly until the plant roots thoroughly.
• During summer: On hot days, give the plant a watering, ideally early in the morning or in the evening, so the soil doesn't dry out completely.
• In winter: Limit watering; winter moisture is more dangerous for it than drought.

If the seedling arrived from a protected environment (greenhouse), it is necessary to accustom it to outdoor conditions gradually so it doesn't suffer shock from sun or cold:

1. First days: Place the plant in partial shade and protect it from direct midday sun and strong wind.
2. Watering: Check the substrate and water if necessary, but do not overwater.
3. Planting: After 3–5 days of hardening off, you can plant it in its permanent location.

Daisies are not extremely demanding on nutrients, but they appreciate fertilization for abundant flowering.

• In spring: Work well-rotted compost into the soil around the plant or use a complete fertilizer for perennials (e.g., Cererit).
• During the season: You can fertilize with a fertilizer with higher potassium and phosphorus content to support flowers. Avoid excess nitrogen – plants would then be leggy, flop over, and bloom less.

While the related common daisy (Bellis perennis) is common in the kitchen, garden Daisies (Leucanthemum x superbum) are not commonly used culinarily. Although they are not explicitly poisonous and young leaves of some Daisy species were historically added to salads, the 'Polaris' variety is bred for ornament, not flavor. We recommend enjoying it in a vase rather than on a plate.

Yes, pruning is very beneficial.

• Ongoing: Remove spent flowers with part of the stem. This encourages the formation of new buds and extends the flowering period.
• After main flowering: You can perform a deeper cutback (complete cut), which supports plant vitality, strengthens the clump, and often leads to repeat flowering at the end of summer.

The 'Polaris' variety belongs to the taller forms, usually growing to a height of 80–90 cm (up to a meter in good conditions). Due to its height and large flowers, it can be prone to falling over, especially after heavy rain or wind. Therefore, it is recommended to place an inconspicuous circular support near it or plant it in a denser arrangement where the plants support each other.

Yellowing of leaves can have several causes:

1. Waterlogging: The most common cause. Roots in heavy or wet soil cannot breathe and rot.
2. Drought: If the plant wilts from drought for a long time, lower leaves yellow and dry out.
3. Exhausted soil: In older clumps, this may be a signal that the plant needs to be transplanted and divided.

The 'Polaris' Daisy is a frost-hardy perennial, but its biggest enemy in winter is not frost, but moisture.

1. In autumn, remove dry stems (or leave them as protection and cut them in spring, which is gentler).
2. Do not pile heavy soil or leaves around the plant for winter, which would hold moisture and cause crown rot.
3. Ideal is a light covering with brushwood, which allows air circulation.

Yes, it is an excellent cut flower.

• When to harvest: Cut flowers at the moment when they are fully open and have a firm, smooth central disc.
• Longevity: In a vase, they last fresh for 7–10 days. Don't forget to change the water daily and trim the stems so they last longer.

This Daisy is a sun lover. Choose a fully sunny spot for it. Regarding soil:

• It should be humus-rich and permeable (common garden soil).
• Watch out for clay and heavy soils: Daisies often suffer in these, rotting in winter and tending to be short-lived.
• If you have heavy soil, lighten it with sand or fine gravel before planting to improve drainage.

Daisies tend to age after a few years (approx. 3–4 years), the center of the clump becomes woody, and the plant blooms less. The solution is rejuvenation by division:

• Early in spring or in autumn, dig up the clump.
• Divide it with a spade or knife into smaller parts (each must have roots and shoots).
• Discard the old woody center and replant young parts from the edges of the clump into improved soil.
