A Proper Winter - by Ben Gaia, www.dialatree.co.nz

Frost





Hooray! The frost has come bang on time, winter bringing the most normal hailstorms and thunder since records began. Now is the time those trees and plants long nurtured throught he tropical summer will reveal whether they will live or die through the South Island's finest climatic offerings. Hail, sleet and a minus three we have had this month, and 110kph winds for good luck. Overnight frosts, ice on the puddles, and this week the maximum was 7 degrees. Snow all over the mountains. A proper winter!

Marginal plants rapidly give up at below zero temperatures, the softer citrus, olives, guavas, pawpaws; the young tamarillo trees, nikau palms, other attepts at exotic palms. Various flowers, fruits and of course the tomatoes all give up the frosty struggle and melt away to withered sticks of mouldy fluff in no time. Some are never attempted again: coffee, mango, rice, lychees. Some like Cherimoya and tamarillo may scrape through under cover.

But there are others who welcome the bite of the alpine snow and the chilly night easterly. The nectarine trees and peaches are delighted, just what we needed they claim; and start showing eager signs of early winter buds ready to flower before any other orchard trees. The apples and pears are also happy but they are going to stay sleeping until the worst of the late winter storms. You can see blossom buds forming in response to the frost, and to the change of day length as the shortest day is passed. Soon the scent of witch hazel will fill the air, and some citrus, well protected, are flowering through the coldest days, though the flowers turn to fungal blobs in a six day thunderstorm. Genoa Lemon, and Lemonade struggle on through the worst. The loquat tree thinks it's spring already, and the bellbirds are fighting over its flowers.

Oak trees and other autumn colour trees like Persimmon are dropping all their leaves bringing up deep soil nutrients and creating a carpet of organic humus soil under their bare branches. Sun shines into the oak woods encouraging all sorts of fungi.





Hazelnut trees, and alder trees are putting out catkins, those delightful dangly, sort of wooden flowers that throw pollen to the wind and create seeds and nuts next summer. Along with the happy bragging bellbirds, they are mating and reproducing on the shortest day at sunrise, seizing the fine cold sunny day to further their species. And the solstice signals longer sunshine hours to follow: some species pick up this information. Many tree seeds will start to sprout at this time despite the cold, signalled by the light of the sun and some mysterious internal clock they carry.

So winter is a relief for trees, it signals the end and the beginning, death and new offspring, the endless cycles of the planet. Shivering in five jumpers and waiting for the dry pine to heat the room... along with the nectarines, I welcome the cold days and the reassuring normality of a Proper Winter.
