“The place we are able to procure seed, we germinate this on a heated seed elevating mattress then develop the seedlings on till we’ve got an acceptable sizes plant that may be planted out within the gardens.”
From the heated sand-based seed-raising beds with overhead automated mist irrigation within the glasshouse some seedlings transfer to the larger greenhouse whereas others are positioned within the open air, and as soon as matured sufficient are then planted.
“We additionally use the glasshouses for drying off bulbs and dahlias when lifted earlier than division and replanting.”
There are additionally some particular vegetation being grown for particular native planting areas, similar to Wakanui and Ōtūwharekai Ashburton Lakes as a part of the council’s biodiversity work.
“These are sometimes species the place the seed is eco-sourced or sourced inside the similar geographical/ ecological location and they’re particular to their inland, lowland, or coastal environments.”
