5TH
SEPTEMBER 2016 - CENTRAL PORTUGAL
So the Autumn (officially
started on the 1st September according to the MET Office) in the
Beiras has begun with another heatwave.
The forecast for the week has temperature well into the 40’s –due to a
South Easterly wind straight from the Sahara.
Anything in the garden that
need refreshment and remained un-watered, is now very dry and crispy. No need to
strim in the orchard, just break of the burnt brown weeds and brush up the
remains. Most wells are now dry so the only water is coming from the mains supply –
constant still, but very expensive. This could be the start of a new wave of
gardening for the next decade and beyond – must get used to conservation and
using minimum of water or only grow between November and May – leave the other
months to Figs, Olives, Oranges, Pomegranates and Vines ( seems rather a Biblical roll call in its simplicity).
So what can survive a
long HOT Drought? Apart from the
previously mentioned ‘Talmudistic’ grouping, consideration could be given to
the myriad of Cactus varieties available. Whilst they enjoy the ‘Wet’ of winter, they are happy to survive with little but the morning dew for four to five
months – even flowering with alacrity and in profusion during the dry time.

Those trees, plants and shrubs that have put down very deep roots (usually
after two or three years) tend to survive, if not thrive, in the dusty high
summer and there are a number of ‘Climbers’ that at least stay green – Solanum and
Plumbago even giving a wonderful display
in the white to dark blue sector. Bougainvillea are enlivening in pink, purple
and yellow.

For those requiring a
more verdant and tasty garden the use of large Tubs (75 litre to 90 litre grape
tubs from the Co-Operativa and €2.80 each, do admirably and don’t collapse after
2 sunny years, like their very expensive terracotta coloured plastic cousins)
will, with the a minimal addition of tap water (tub usually requires around
3litres per day against the same ‘ground planting’ using at least 12 litres).
These tubs can be filled with a ‘Tailor Made’ growing compost for the
particular plant to be cultured and can be very specifically fed and watered
throughout the growing and fruiting season to encourage spectacular results.
Tomatoes, Aubergines,
Peppers, Chillis, and Cucumbers all thrive in ‘Tub Culture’ with their cropping
season being extended well into the winter. Peppers and Chillis can simply be cut
back to 150 mm in January and the new season starts 2 months earlier than those
sown each year from seed. Usually the crop is much larger in the second to
fourth years.

Raspberries, blueberries,
gooseberries and rhubarb (Yes rhubarb can be grown in Portugal in a tub) all
thrive in their own individual space,
even Sweet Corn (sixty days from planting to eating) and leeks (maybe the sweetest
you have ever tasted and they will be available with all year round with
progressive planting) all perform rather well. The only way to find out is to
try the method. You never know you may be saving the planet!
Needless to say, most
of the summer blooming plants (and 80% of the winter flowering) are Tub grown.
The half size 45 litre capacity units are best for bulbs Plant Tulips by the
end of September for a display next March, and Lily bulbs by the end of October
for best results next year. (Don’t over water). Cyclamens perform best in small
pots. Plant in October for winter flowering under the trees.
Dahlias love the
solitude of individual planting and flower profusely if regularly fed and watered
well into November or December if the temperatures hold up.

Roses can be grown in big tubs. Water in
summer leave dry in winter, and will bloom for ten months a year. Best varieties
for container growing are ‘Bush’ plants. Climbers and Ramblers out grow the tub in a
first season.
 |
Some roses just keep on going |
Now is the time to top
up all your current Tubs and Pots with ‘estrume’(Horse Manure) as most will
already have lost a fifth of the compost washed out by watering and they are
all desperate for a good feed. If you dislike the idea of ‘estrume’ use ‘Blue
Ball’ Fertilizer or a ‘Liquid Feed’ of choice but DO FEED now if the garden is
to remain in its prime until Christmas.

In case you didn't believe me! |
The thermometer has
just topped ‘40’ degrees and it’s not yet Noon. At last the tintinabulation of
the Head Gardener’s bell with the summons to a ‘Hosing Down’
and coffee –
must dash,
see you soon
