A hot, dry autumn in Spain and Portugal

Even as September melts into October, Spain is hot and dry. Alas Professor Higgins had it entirely wrong when he made Eliza Doolittle recite that the rain in Spain falls mainly on the plain. He certainly was not referring to the plains beyond Madrid where the rain clearly falls on rare occasions at best. They are dry and arid, too inhospitable even for the hardy olive tree. Nearer the mountains (the sierras, but more hills than mountains by NZ standards), it is clear that more rain falls. There were olives as far as the eye could see. Don`t be imagining romantic old olive groves. This was monoculture on an industrial scale (viz a viz Blenheim vineyards). I had to ask about harvesting. It seemed incomprehensible that such vast acreages are still picked by hand but apparently that is the case. Teams of itinerant pickers, many of North African origin, travel the area at harvest time. I suspect I have seen the origin of all the imported olive oil on the shelves of every supermarket at home. Maybe.

The olives are usually planted in groups of three, each leaning outwards to grab its own space, and pruned to around 2.5 metres in height. Presumably this makes picking easier because the olive tree, left to its own devices, reaches higher. We are working to keep our one at home down to about 4 metres.

The olive plantations looked to be corporate farming, much as our dairy farming is headed. The era of the small family farm appeared to be over in much of the countryside that we passed through. Often there were no residences visible for considerable distances and no indications of boundaries to suggest the smaller holdings of old. It was interesting to reflect on the debate at home regarding lifestylers populating our countryside. We had been discussing it before I left and came to the conclusion that, on balance, small holdings and lifestyle blocks add a welcome diversity to the countryside. Without lifestylers planting gardens, shelter belts, home orchards and landscape trees, Taranaki could well become even more of the unrelieved green desert favoured by modern dairy farming methods. In the centre and south of Spain, it is not a green desert but red-brown dirt with multitudinous grey-green olive trees and not a lot else.

In urban areas, living is in high density housing, usually 3 to 5 stories high. I peered at balconies and roof terraces, looking for signs of green-fingered locals which is so evident in British high density housing. It is not here. I came to the conclusion that your average Spaniard does not nurture an irrepressible desire to grow plants and the G.I.Y. (that is: grow it yourself) and back to nature drive that is currently so strong in NZ, Australia and Britain is not to be seen. Any outdoor space is rare. The delightful inner courtyard or patio which has a debt to Moorish ancestors must be the preserve of the wealthy. A mere six, or maybe nine square metres of outdoor space is a privilege in many parts of urban Spain. But in a climate where temperatures can soar to 40 degrees (and stay there), a cool house is more desirable than al fresco living.

Were it not for the public plantings, this would be an even more austere environment. Fortunately, there has been a heavy investment in greening urban spaces in recent times. Not grass, which does not grow here unless irrigated. Ground surfaces are all paved but trees are being planted in abundance. Madrid has the harshest of climates – very hot and dry in summer and remarkably cold and dry in winter – so there is not a large plant palette to work with. The stately plane tree is the most dominant but it was interesting to see the number of Australian plants being used, most notably the good old gum or eucalyptus.

We just do not grow plane trees well at home in Taranaki (we are too wet and they are inclined to drop limbs too readily) so we don´t get to enjoy their wonderful bark. There does not appear to be any fear of large trees. The bigger the better for they provide welcome shade.

Cordoba has a milder climate and orange trees dominate as a street tree. Flowering time must be magical with the strong scent of orange blossom hanging in the air. I briefly indulged a fantasy of the entire local populace being able to gather tree-ripened oranges in season. After all, they have nowhere to grow their own. No. I was told that it is a bitter orange which is harvested commercially and shipped off to the jam factory!

By the time we reached Cadiz on the southern coast, it was the palm tree that prevailed. As far as I can work out, (and I freely own up to the sparsest knowledge of palms at best), it is almost exclusively the common date palm which Google tells me is Phoenix dactylifera. It is certainly a most handsome palm and remarkably tolerant of salt winds, growing even on the waterfronts. Mind you, it is so common that locals may well take a scathing attitude similar to Taranaki people with our adaptable pohutakawa.

Crossing to Portugal, it became clear that more rain falls. I even saw a little green grass with no evidence of irrigation. In Lagos where I write (prounced Lagoosh and not to be confused with Lagos in Nigeria), the date palms continue but the real delight is the large number of blue-as-blue jacaranda trees which continue to flower even as autumn starts. The New Zealand cabbage trees interplanted between the date palms by the river do not look such happy campers, alas.

Yuccas and oleanders flourish everywhere – both plant families which prefer drier conditions. But just to prove that bad taste crosses all borders, the new cultivar of oleander favoured in public plantings in Seville was a thoroughly nasty novelty selection – yellow and green variegated foliage with dirty pink flowers. I think we saw a new spirea sporting a similar colour scheme in the United Kingdom last year.

Tales of the gardens I have visited will have to wait until after I return. Yes there are gardens and the historical gardens of Andalucia are rooted in impossibly romantic Moorish architecture. At the time of writing, I have yet to see the famous gardens of Lisboa and Sintra in Portugal. I have contemplated an Outdoor Classroom on the DIY Moorish garden but the prospect scared me. The likelihood of achieving something unbelievably naff is greater than the likelihood of successfully adapting such a unique and culturally distant style to home!

In the garden this week: October 8, 2010

  • Leave spring bulbs to die down at their own speed, no matter how untidy they look. Resist the temptation to tie the foliage in knots because this interferes with the plant’s ability to build up its energy for next season’s appearance. If flopping foliage is a real problem, construct a low trellis out of twigs or old bamboo stakes criss-crossed to keep the plants tidier.
  • Keep earthing up potatoes (piling on the garden soil to build ever higher mounds) to stop the tubers going green. Both potatoes and broad beans may need a copper spray to stop rust or blight taking hold.
  • Basil can be started now but it will need to be kept warm for a few weeks now before planting out in the garden.
  • Parsley can be sown any time but if you lack a perpetual supply self seeding down and keeping you going when green vegetables are in short supply, you can sow it down. A visiting expert here advocates sowing the seed, covering it and then head out with jug of boiling water and pour it over the row to aid germination.
  • It is the last chance for getting a crop of Florence fennel (finocchio) in for eating over summer. After this, you are best to leave it until late summer or early autumn and sow then for winter harvest because it will tend to bolt to seed too early over summer. We rate this as a fantastically versatile vegetable and are working to increase production on a regular basis here.
  • Time is running out for winter/spring pruning. Shortly it will be time to put away all the loppers and the cutters until the summer prune of cherry trees calls.

Plant Collector: Anopterus glandulosa

 

Anopterus glandulosa - a slow growing treasure

Anopterus glandulosa - a slow growing treasure

It did take a long time for our Anopterus glandulosa to do much other than just sit and put up a few racemes of flowers each spring but eventually it grew a little and after a decade (possibly more than a decade, in fact) it just gets better every year. Its flowers look like lily-of-the-valley but this is an evergreen shrub from Tasmania. The literature tells me it can make a small tree but at the rate it is growing, that might be when our grandchildren (who have yet to make an appearance) are adults. I can see why it is rated as rare because this is not a quick turn-over shrub for the trade so if you ever see it offered for sale, grab it because you may be looking a long time to find it again. The leaves are long, leathery, shiny dark green with saw-toothed edges. Even without its flowers, it is a tidy little evergreen shrub which keeps good form without needing pruning and then for many weeks in spring, it is adorned with its racemes of pink buds opening to white flowers.

 

There are apparently only two species of anopterus and the other member of the family must be of negligible merit because most of the references only record glandulosa. They are closely related to escallonias which readers may know for a hedging option. If you find somebody with an anopterus, you may be able to raise it successfully from seed.

Plant Collector: Calanthe orchids

Calanthe orchids - happy growing in our woodland

Calanthe orchids - happy growing in our woodland

Orchids are one of the largest and most complex groups in the plant world – fearfully complicated to try and navigate your way through. Our interest here is in orchids as garden plants and one of the star performers is the calanthe family. These are called ground orchids or terrestrial orchids – in other words they are happy to grow in good garden soil. In the right conditions, you can plant them and leave them alone for many years where they just gently build up and make a better display with more flower spikes. There are well over 150 different species of calanthes and inevitably some will be better and showier as garden plants in our conditions than others. There is a bit of a question mark over the correct name for this lovely soft yellow one- probably a form of sieboldii or striata. Note: I have now been informed that in fact it is Calanthe ‘Higo’ (C. sieboldii x C. aristulifera) which makes sense to us.

Most of the calanthes come from tropical and sub tropical Asia and are generally evergreen. Presumably the forms thriving with us are the sub tropical types because tropical, we are not. We use them as woodland plants and have only once ever had them tickled up by a vicious frost. Their only downside is that they are quite leafy and the foliage hangs on for grim death long after it has become tatty and shredded. They benefit from an occasional tidy up. The new growth comes in spring and is quite lush so that every year garden visitors ask us which variety the yellow flowered hosta is.

Probably because orchids are such a complex plant family, orchid societies continue to grow, show and share when many other specialist groups have gone out of existence. They are a friendly and knowledgeable bunch and if you want to start building up a collection, either joining the local branch or visiting their shows is the best place to start.

  • Ideally you should have finished your spring fertilising round so give this priority if you haven’t.
  • Broad beans need to be staked to stop them from falling over. Pinch out the tops to stop them getting too tall. These tender tops are delicious eaten as fresh greens.
  • Peas also need something to climb up. We tend to use a stretch of wire netting held by wooden stakes at each end so these frames can be moved around the vegetable garden as required – functional but not aesthetic. Woven willow supports or bamboo structures look more ornamental but take more time.
  • As evergreen azaleas finish flowering, they can be clipped or pruned and shaped – with hedgeclippers if you wish. These are tough plants that will shoot again from bare wood so you can prune hard if they are looking scruffy or too leggy. You can even cut them off just above ground level if you are into drastic rejuvenation.
  • If you have forgotten about your feijoa bushes, you can still get in and give them a thin and a feed. Don’t clip off all the tips or you will be cutting off next year’s potential harvest – thin out entire branches if necessary. A more open, airy bushy will set bigger fruit.
  • You can get your first crop of dwarf beans and runner beans sown in all but the coldest areas.
  • Ideally you should have dug over the areas of the vegetable garden which are to be planted out in a few weeks. Certainly you should have dug in any green crops. If you use animal manures, get them incorporated now so they get dispersed in the soil before you start planting. Keep raking over the freshly dug areas to stop compacting and to disturb the freshly germinating weeds.
