Evergreens
Conifers, thujas, cypresses, yews — year-round green, special nutrient demand
Evergreens — conifers, thujas, cypresses, yews, junipers, cherry laurels, hollies, mahonias and box — are decorative all year round and, because they renew their foliage continuously, require a special water and nutrient supply.
Application conditions: Soil pH 6–7.5, organic matter min. 1.5%. For soil-applied ConiTrio spraying, from late March to May, when the soil is already around 10 °C and root activity has begun.
Soil treatment
Microbiological soil inoculation and organic-matter supply
| # | Recommended timing | Product | Dose | Water |
|---|---|---|---|---|
| 1. | When preparing the planting hole, mixed into the backfill soil + at planting, mixed into the settling-in water | Natur Fertil + Natur ConiTrio | 200–400 g/plant (Fertil) + 10 mL (ConiTrio) | +10 l water (ConiTrio) |
On established, multi-year hedges every spring: spread it along the base, around the drip line, work it shallowly into the top 2–5 cm, then water it in thoroughly. For specimen plants, apply in a circle 20–50 cm from the trunk — it must not be placed directly against the trunk or root collar. On established stands, ConiTrio is applied to the soil at 10 mL / 100 m² with 10 L of water, followed by watering in. It is particularly useful for thuja, Leyland cypress and columnar cypresses — in the first year, root loss and soil-borne fungi cause most problems.
Application method
Apply the soil treatment as a water-diluted solution by spraying, then incorporate it into the topsoil. It can be applied together with herbicide and liquid N fertilizer.
Foliar fertilizer / Crop treatment
Biostimulant and foliar treatments by season
| # | Recommended timing | Foliar fertilizer | Dose | Water |
|---|---|---|---|---|
| 1. | Late March – late May, during intensive shoot growth, every 2–4 weeks | Natur Plasma T + Natur Active + MONO Mg | 20 + 40 + 10 mL / 100 m² (2 + 4 + 1 L/ha) | 10–40 L/ 100 m² (1000–4000 L/ha) |
| 2. | In midsummer, for regeneration after heat stress | Natur Active + MONO Mg | 40 + 10 mL / 100 m² (4 + 1 L/ha) | 10–40 L/ 100 m² (1000–4000 L/ha) |
| 3. | September — autumn regeneration, preparation for winter | Natur Plasma T + MONO K | 20 + 10 mL / 100 m² (2 + 1 L/ha) | 10–40 L/ 100 m² (1000–4000 L/ha) |
Add the water to the sprayer first, then the foliar fertilisers; after thorough mixing, spray with a fine mist. Spring browning is often caused by winter water shortage — alongside autumn conditioning, water supply is at least as important. Water evergreens in winter too, during frost-free periods! The 13 nutrients in Natur Active — including calcium and cobalt — strongly support the vegetative growth of evergreens; on yellowing thuja or faded foliage, MONO Mg can bring rapid improvement (it is the central element of chlorophyll).
Application conditions
Temperature below 25 °C, calm conditions. During summer heatwaves, treat in the early morning or evening. When tank-mixing with plant protection products, add the Natur products to the spray solution last, immediately before application.
