Ludwig’s Vigolonger by Kirchhoffs (4.5kg).
Ludwig’s Vigolonger by Kirchhoffs is a multi-coated, controlled-release general fertilizer designed for one application per growing season. It releases balanced nutrients over about 8 months so plants get a steadier feed instead of monthly top-ups. The analysis is 15:3:12 (30) + S + Me (approximately 150 g/kg nitrogen, 30 g/kg phosphorus, 120 g/kg potassium and 70 g/kg sulphur, plus micro-elements). Ludwig’s Vigolonger cannot burn roots when applied as directed.
The 4.5kg tub is intended for easy, precise dosing. Apply in early spring after pruning, or at any time during the growing period. Spread the granules over the root zone and work them into the top 25 cm of soil so water can carry nutrients to the roots. This formulation is promoted for efficient use of fertilizer and reduced risk of groundwater contamination compared with frequent soluble feeding.
What Ludwig’s Vigolonger can be used for:
- Roses (standard bushes, climbers and new plantings)
- Annuals
- Vegetables
- Ornamental flowers
- Ground covers
- Trees
- Container and pot plants
It is a general garden fertilizer rather than a rose-only product. The controlled-release coating supports consistent growth through the season without the peaks and troughs of frequent soluble feeds.
How to apply Ludwig’s Vigolonger:
- Established garden roses and most plants: 75 g (one measuring cup) evenly over a root zone of about 1 m diameter. Use 150 g for large climbers. Fork into the upper 25 cm of soil.
- New plantings: Mix one measuring cup into the backfill soil around the plant.
- Beds before planting: 75 g per square metre, mixed into the top 25 cm.
- Pots: Mix 7 g per litre of potting mix before planting. For established containers, make holes at different depths, add the calculated amount, close the holes and water well.
Water after application. One seasonal application is the standard programme; optional extra boosts with a product such as Vigorosa are sometimes used later in the season if extra flowering is wanted.
