We have been in the house for one year last weekend. We have done a lot of work and there is a lot still to do.
There have been a couple of cabbage white butterflies spotted over the last week in the garden on sunny days - they are still not impressed with the lack of brassicas - and we lost a kanuka in the recent high winds, highlighting that the ground is still not stable. I have also bought a potting shed, which is amazing in New Zealand as the concept of a half greenhouse, half shed is not one that has caught on here. However, I have nowhere to put it yet. Hmm, more planning needed.
I realise that the first project plan actions I wrote was really only the first year's work or vague plans, so it's time to update it for the next year in the garden.
Butterfly Garden
Finish planting up the new garden beds and widened borders of the butterfly garden
Grow from seed annuals that will fill the spaces initially and as many perennials as possible to save money
Note when each plant flowers and if pollinators feed from it
Review the performance of each butterfly garden plant at the end of the season. If plants do not work where they are initially planted, they can be moved in autumn / winter. Plants may grow bigger than expected, or need dividing or removing, so this will be an ongoing review process.
Ensure there are enough plants flowering for year round nectar. Research and plant more if there are gaps in the year.
Monitor wind levels in the butterfly garden and see if more shelter plants are necessary.
Record the wildlife I find in the new garden, including undertaking butterfly counts on sunny days.

Main Bush
Plan an access route through the main bush for maintenance and to access the stream.
Remove the monkey apple saplings that have been missed.
Assess where more native plants are needed and make plans to buy or grow these. I wasn't able to buy all the species I wanted to for the 2025 planting season, like akepiro and mingimingi, so another planting season is required.

Top Bush
Create access pathways
Clear all the invasive ginger, Japanese honeysuckle, monstera and moth plant
Remove the large monkey apple on the northern border that is creating issues for the neighbour's house
Plan and plant the area around the removed monkey apple so that when the root system rots, the ground does not fall away
Build deck for potting shed
Continue to trap introduced predators
Plant up the space where the ginger has been cleared with natives once the potting shed is in

Stream
Improve access to the stream for ongoing work
Undertake a mud scrape to see what invertebrate life is in the stream. If it is successful, do this on a regular basis
When water levels have dropped, assess the damage and plan how the erosion around the stream could be slowed
In concert, plan measures to improve the area for wildlife
Observe wildlife that are using the stream as a water source - are butterflies?
Plant a mini-pond in a tub to see if this attracts animals that prefer still water (assuming the planned in-ground pond is not created this year)
