Spring in the woodland gardens

Red Hippeastrum aulicum, pale yellow calanthe orchids and Crinum moorei varegata are all mainstays of our woodland plantings

It has been a difficult week, so all I have to entertain readers with this week is scenes from the spring woodland. We like highly detailed woodland.

High shade is the key – here in the Avenue Garden

The key to woodland gardening here is to manage light levels. The charming scenes we see of European and British woodlands – the expanse of white birches underplanted with snowdrops and crocuses and that sort of thing – are beneath deciduous trees which let light in during winter and shoulder seasons.

Trilliums are a bit marginal in our climate so it is always a thrill to see their understated charm
Scadoxus, however, are so happy here that they have pretty much naturalised themselves. This is S. puniceus which flowers in spring. S. katherinae will feature in summer.

In Aotearoa, somewhere over 99% of our native flora is evergreen and most people tend to garden with exotic evergreens as a preference. In our years of retail, I encountered many gardeners who would reject anything deciduous. As a result, we don’t get the seasonal light coming into shaded areas. Also, with our rapid growth rates, trees tend to grow much larger. As UK author and horticulturist, John Hillier inscribed in our copy of Hiller Manual of Trees and Shrubs, ‘double heights and halve the time for New Zealand’. Dare I say it, UK woodlands often look quite spindly to my eyes.

Orchids, we have a few. These are pleiones. We lost all the yellow ones that need more of a winter chill but the purple, lilac and white varieties thrive under laissez faire management in the woodland garden.

Woodland gardening means dappled light and some shade, but not deep shade. There aren’t many flowering plants that will perform in deep shade. Lifting, limbing and thinning are needed to create high shade and to allow reasonable light levels below.

The Rimu Avenue has such a dense network of roots from trees that are now over 150 years old that we have had to rebuild soil below to allow underplanting

There are also times when the soils below will need some extra texture, volume and replenishment in order to get small plants established. Small plants at ground level won’t thrive if they are bedded in amongst dense tree roots which have dried out the surface.

It is not all bulbs in our woodlands. Azaleas, vireya rhododendrons, camellias, hydrangeas and other shrubs add mid-level detail and height.

On the upside, even high shade and dappled light is enough to hugely reduce weed growth and the visual delight lies both in the detail below and the play of light. It is much lower maintenance than gardening in full sun.

Why a difficult week, you may wonder. We nearly lost our beloved dog Ralph to poison – not our poison and not deliberate but traumatic, nonetheless. We thought he was going to die on Tuesday night. He is still recovering and we are now confident he will survive, although there is a possibility of long-term organ damage.

Ralph in happier times

It is perhaps little understood in this country that our predator-free goals are only achievable with the extremely widespread use of slow-acting poisons, one of which has no antidote. There is a pretty gung-ho attitude and light regulation when it comes to the use of poison. We choose not to use it and will trap and shoot instead. Ralph’s ordeal this week is a reminder to us of why we made that decision. Our lives would have been so much poorer had he died so needlessly and in distress.

Charming erythroniums or dogs tooth violets – best left undisturbed as much as possible because their long, thin bulbs sit vertically in the soil and are fearfully easy to snap when digging.
