Hi

Last weekend we decided to make the most of some time off (escaping the garden renovations) and headed up to the Coromandel. A couple of things really stood out for me, as I just can’t get away from my horticultural hat even when on holiday! One was the different plants which live only a hundred kilometres or so away from the Waikato. Climate plays a large role in how well plants can grow and thrive. Humans can cope with all sorts of environments and can be found living in sweltering deserts and freezing arctic conditions. Plants however, have adapted to the environment in which they originate and obviously don’t move around much (apart from as passengers in or on animals or spread by the wind and water). Not so easy for them to stick on a heater or a puffer jacket! 
Near the beach you can find quite different trees and shrubs which won’t survive in our inland climate. To be honest most of us wanted to move to the beach last week, just saying. Some of the plants in our display garden, which are normally ok at this time of year, have been hit by the very severe frosts we have experienced this winter. Sorry guys, that one was out of the box. FYI we will have Tamarillos and Avocados in October, hopefully when frosts are a distant memory. 

 
 

The second thing I noticed was that even in the same environment, the same plants can grow quite differently. This was obvious when looking at the palms along the beachfront at Whitianga (see image below). The same plant variety, planted in the same environment with identical soil, sun, water etc. and some are many metres bigger than others. Huh??? The answer is that these plants are not actually growing in the same place at the same time – there are subtle differences in soil composition, water availability and plant responses so that you just don’t get identical growth. This is also something many customers ask about – why is one plant in my hedge growing well and the next one not doing so good? The answer is generally related to the soil – not seen but still important. It could be lack of (or too much) water, contamination, competing root systems, or a pocket of stones, clay or some other unhelpful component which is affecting the ability of the roots to extract important nutrients. So yes, you can help them out by adding compost (to dry sandy soil), gypsum (to break up clay) or fertiliser (to poor soils or very sandy ones that don’t hold nutrients). 

Training your plants

People being control freaks, yes, I mean you, like to control how their plant grows. One of the best ways to control plants is through pruning and training them and one example of this is espaliering. This practice probably started with the Egyptians, but was formally developed into a technique for horticulture by the Romans in ancient times and then adopted throughout Europe in the Middle Ages to grow plants inside castles, where there is limited space, and to protect them. Gardeners at Versailles in France developed the practice to utilise the stone walls, which absorb heat, to increase crop yields in Europe’s cold climate  when temperatures took a dive for a few hundred years (during the last Little Ice Age). 

For us, with our more compact sections and limited space, espaliering makes perfect sense. You can utilise your fences and walls to grow productive trees with a little know-how. Plants which are easy to espalier include Apples, Pears, Figs and ornamentals such as Camellias, Flowering Quince (Chaenomeles) and Firethorn (Pyracantha). The basic requirement is something which can take heavy pruning, and still retain its fruiting or flowering capability, and that has flexible young growth. It’s important to have a good set-up of supporting wires or trellis to help hold the new growth in position so that it can achieve the desired shape. This is usually horizontal layers, but can also be a fan or cordon shape. Check out this link to our website for more information.
The technique involves cutting a young unbranched plant just below the level of the first set of wires and then training the shoots which develop along the wires retaining only three – one for the upright and two either side. Horizontal growth is generally slower and more likely to produce fruit and flowers so the first summer after selecting these side shoots you should tie them on a 45-degree angle and then tie to horizontal the following winter. The central shoot can be tied to an upright cane and then in winter cut just below the next set of wires to begin the process again. In spring pinch off shoots that grow towards or away from the wall, prune frequently and lightly; in summer trim back any side shoots that grow from the main stem to three leaves. This process will take a few years to complete and involves regular pruning to keep the shape and control growth. Get out your secateurs and away you go.

New at the Nursery

When sitting down to write the newsletter, I had lots of things to choose to write about because the garden centre is starting to fill up now that potting is completed. We have just received our delightful Delphiniums which are favourites for flower gardeners due to their large spectacular flowers and vibrant colours. Delphiniums are part of the buttercup family and named after the unopened flower (apparently it looks like a dolphin??). On the animal theme, the central section of the individual floret of the flower is sometimes a different colour and is called a “bee”. The key thing to watch with these pretties is that they need staking to support their tall flowers and they are susceptible to slug and snail damage when young – be prepared!

Ericas

Also just arrived are a selection of Ericas, many of which originate in South Africa, although there are also varieties native to Europe and the Mediterranean. Erica cerinthoides is a brilliant plant for rockeries and garden beds or can be grown in a pot. They prefer a sunny situation and like acid soil – they may need a little protection from severe frosts. Be sure to water well in summer when plants are establishing and add mulch to preserve soil moisture. Some Ericas have developed smart survival techniques including some with a sticky coating on the stems and flowers which trap insects which steal nectar without pollinating – no freeloaders here thanks. The flower shape is adapted to the pollinators too, with some formed into tubes for sunbirds and some small flowering ones reliant on the wind. They are generally great for a bit of late winter colour before anything else is flowering.

Banksias

Another popular and unusual group new in store are the Banksias. As mentioned above, they are well adapted to coastal conditions and best grown in frost-free environments. If these plants wore clothes, it would be board shorts and sunnies, not beanies and gloves! One of their key claims to fame is their nectar-filled flowers which attract bird-life. If you plant some banksias, you will delight the tuis and wax eyes as they will have a feast of nectar. These plants were named in honour of Sir Joseph Banks who was passionate about collecting plants. He travelled from his native Britain to North America in the 1760’s and then around the world with Captain Cook on a mammoth journey which took 3 years (1768-71) and reached New Zealand and Australia. Banksias are almost all endemic to Australia, and have adapted to Aussie conditions; some of the seed pods are shut tight and only open when torched by a bush fire. Plant in full sun where there is excellent drainage and you will be rewarded in due course with an unusual and useful flower display.

Last chance for Large Tree bargains

It's your last chance to buy our bare-rooted trees – we have some monster specimens left in the crates in the car-park including some Poplars – Kawa and Crow’s Nest and Oriental plane trees. These will be potted up next week so get in quick and save yourself some dollars. These are 3m+ in height so will make instant shade or shelter trees once planted.

Hope your weekend is enjoyable. Come in for a chat or a wander if you are  looking for inspiration. Regards, Tracy.

Cheers from Lloyd, Tony and the Wairere Team.
