The greenhouse has been a terrific success for the tomatoes, sweet peppers and chilli peppers.
I was worried that it would be too hot, but the Coolaroo shading the Bon Viveur put up in May seems to have worked well, even though the south side and the roof have not yet been shaded.
It’s a 50% shading from Australia and seems mainly to be used for sails and shaded pergolas in the garden. Not my first choice, but it works. Although with the disadvantage that it has been trapping a fair few butterflies and moths, for whom I feel sorry every day as I rush past in the heat.
Perhaps some more traditional green shading for the roof next year would keep it cooler, but temperatures have not risen about 35.2 degrees C. Sounds bad, but the thermometer on the supper terrace (open on all sides, but shaded) shows me temperatures have been up to 36.8 degrees there.
I received a very welcome present of a vine cutting from a friend, and I’m planning to use it as a more natural ‘shading’ – at the moment the little thing is trying to climb up the Coolaroo – so pretty successful! I’m also toying with the idea of a tub of water in the centre, which would be filled with cooling water and in which, who knows, I might even be able to grow a tiny waterlily like ‘Perry’s Baby Red’. Mmm … could be nice.
At the beginning of July we also put in the louvre ventilation purchased with the greenhouse, but not installed straight off. Instantly we noticed a really big difference in air-flow.
So – my bad dreams of the whole thing exploding in a burst of broken glass and melted metal in the first summer turned out to just be nightmares.
I wish I had started my annual seeds off earlier, however. I was forced to sow everything at the beginning of April, since I was away at the end of March and knew that everything would die if left untended.
In some cases this was a big mistake, because it meant that I was still planting out in the second half of June when the heat struck us – much earlier than usual this year. The heat came so early, in fact, that my cannas and castor oil plants have never seen soil and remain in pots. At least the cannas will be fine for next year, but they’ll need to be planted out as soon as possible after the Saints de glace (Ice Saints) next year, so quickly after 11-13 May.
For some annuals the heat was too much – they should have seen their permanent summer positions by the end of May, latest. I was so excited about the good germination of little Rudbeckia ‘Cappuchino’. But when planted out in pots in mid-June, no amount of spraying over could save them from shrivelling in the sun. I think I have only 2 plants left. Other failures were my little ‘Cactus Mix’ dahlias, from Sarah Raven. The plants in the street (shaded for some of the day) are oksh, but those in the garden have never really found their feet after first being ravaged by slugs and then exposed to fierce sun as struggling babies.
But the joy of watching all those little seedlings germinate so easily and then grow into small plants that were – for the first time at Chatillon – not etiolated and miserable will not be forgotten in a hurry. There’s always next year.
We had some shading left, so the BV created a little canopy over my frame where I attempt to grow lettuce, radish, carrots and rocket. It’s working quite nicely (sprayed over once a day), but I’m not having any luck with germinating lettuce in there at the moment. Predictably, since lettuce tends not to germinate above 26 degrees C. Those days are far behind us now!
The tomatoes in the greenhouse are fabulous! I grew two from Thompson & Morgan called ‘Big Daddy’ and ‘Mountain Magic’, as well as a tomato reputed to be the best for pizzas – ‘Cuore di Bue’.
Pointless to tell the BV that with three plants we would, if lucky, have enough fruit for three pizzas. Luckily, the ‘Cuore di Bue’ are equally lovely in sandwiches and on burgers.
The tomatoes show heat stress by rolling their lower leaves, but I’ve been cutting those away and they are ripening nicely. Similarly, the best sweet peppers (‘Californian Wonder’) that I’ve ever had and already some nice green chillis from ‘Joe’s Long’. The last is a variety I strongly recommend. It produces prolifically, even in the open ground here – so much so that I still have dried chillis in the kitchen that I grew about 3 years ago. I think I’m going to have a glut this year because I’m growing 5 plants.
The sweet peppers should be thinned – but I’m so proud of them! I’ve also read that you should prune them to open the centres up a little and ripen the fruit. Next year.
I even have two melons (I know, but I’m only a beginner!) and the best pot herbs – marjoram, basil and lemon basil – I’ve ever managed to raise here.
The greenhouse was definitely at its most exciting when all the annuals were germinating in April. But the late sowings meant that the newly planted sweet peas struggled to survive the sudden onslaught of heat in June. The delphinium seed that I so lovingly moistened with damp tea towels were a complete flop, because the temperatures had risen so that I panicked a little and started to move them around – up to the house where, predictably, they were frazzled by sun in the space of an afternoon.
The lupins, ‘Chandeleer’ (pale yellow) and ‘The Governor’ (blue) were my greatest sadness. I don’t know what I’m doing, but I’m not succeeding. I lost a lot of seedlings when they were pricked out into lovingly purchased John Innes No. 2. Then I noticed that they were yellowing (chlorosis) and potted them on. Instant death. Next year I’ll not give up and I’ll try a peat-based compost and restrict watering to rain water (our water is very, very hard). A friend to whom I gave some seedlings says hers are doing brilliantly – so it must be my poor cultivation technique – possibly over-watering? Always something to learn!
Happy Eclipse season! I hope to be back very soon. August is my most hated month and I’ve set myself the challenge of posting very regularly to compensate. We’ll see …
