ulkokasveille

Ulkokasveille is a term used in Finnish gardening and horticultural contexts to describe products, practices, or guidance intended specifically for outdoor plants. It is not a formal scientific term or a single standardized product, but rather a label that retailers and guides apply to categorize items suitable for use outside in outdoor conditions. The word combines ulko, meaning outside or outdoor, with kasville, the illative/allative form of kasvi (plant), roughly translated as “for outdoor plants.”

In practice, ulkokasveille can refer to a range of offerings. This can include outdoor-specific fertilizers and soil conditioners, frost-protection materials such as coverings, and pest or disease controls formulated for plants exposed to outdoor environments. It also encompasses care instructions and installation guidance tailored to outdoor conditions, including climate considerations typical of northern regions.

The term is not governed by a single standardized definition, and its exact scope may vary between retailers and publications. It is commonly used in consumer-facing contexts, marketing materials, and shopping guides to signal suitability for outdoor growth rather than for indoor cultivation. Because there is no formal regulatory standard tied to the label, customers are advised to read product specifications and usage instructions carefully.
