This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).

Vid containerodling av buskar, i plantskola, är bevattning essentiellt för produktionen. Det finns flera olika typer av bevattningssystem, två vanliga system är droppbevattning och rampbevattning. En plantskola som står inför att utöka sin produktion måste välja vilket bevattningssystem som är lämpligt baserat på plantskolans förutsättningar. För att underlätta valet har en jämförelse mellan de två bevattningssystemen gjorts. För att kunna jämföra bevattningssystemen rättvist måste först begreppet bevattningseffektivitet redas ut.

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.
