Gosh, absolutely no postings so far in December ... I must be in holiday mode! If only, but things have been a bit quiet here in the garden. With all the rain storms there has been little need to water anything, and all the flowering beauties don't need any help from me. They know what to do.
And so in the middle of this festive season snooze all I really want to say is I hope everyone has a safe and delicious festive season. This garden blog will continue to update occasionally, whenever something worth talking about occurs, and so until then, here is the latest from Amateur Land.
Our baby frangipani 'Serendipity' is looking good all over. Lots of amazingly multi-coloured flowers and plenty of new healthy growth. I think it likes it here.
I always feel duty-bound to report my failures as well as the successes, and this pretty pink hydrangea might seem a big success when Pam pops some into a vase in the living room, but the sad fact is that I was hoping they'd be blue. Last season I tried to acidify the soil in an effort to encourage blueness. Nothing doing. So then this year I've bought a "blueing" fertiliser, followed the packet directions ... and this is the result so far.
But let's finish my festive well-wishing on a positive note. The bonsai curry leaf trees are not only still alive, they are thriving. And some radical pruning a few months back (which for a week or two looked more like the kiss of death than the kiss of life) has promoted much bushier growth from both. So far so good, but with growing bonsais from seed, it's a years-long project and this is merely a good year.
So let's end 2018 on that note. If 2018 has been a good year for you, may 2019 be even better.
And if 2018 wasn't up there as a great one — a bit like my hydrangeas — then I hope 2019 is blessed with some lush curry leaf growth, even if that means life might need a bit of pruning here and there before things improve.
Merry Christmas, Happy New Year, and have a great 2019!
I thought as much ... the "blue" hydrangeas I planted recently are just completely normal hydrangeas which turn pink in alkaline soils, or turn blue in acid soils. Mine are a lilac colour, which isn't what I want, and so here's the story of giving my lilac hydrangeas a case of the hydrangea blues. It isn't rocket science, but it is science.
See what I mean? Those large flower petals are the originals. They're not a deep enough colour to be truly purple, they're a bit further along the colour wheel towards the pink end of the spectrum. And so that means my soil pH in this spot is probably somewhere about 5.5 to 6. The next lot of baby buds coming through are looking a lot bluer, though.
Normally, my garden soil is more down the acid end of the spectrum, somewhere about pH 5, and that should produce nice blue hydrangeas. However, the soil in this part of the garden is about 50 per cent homemade compost, and I guess that's why its pH is a bit higher (my guess is something closer to pH 6).
None of this is a problem, of course. In fact it's just another excuse for some good gardening fun. After much Googling and reading, I realised there are two ways you can go about turning your hydrangeas blue.
Option A is to change the soil pH itself on a semi-permanent basis, using either sulphur powder or liquid sulphur. (And it is also spelled "sulfur" on some product labels, which apparently is how the scientific community has agreed it should be spelled). This is slower acting than option B, but is a more long-lasting, possibly permanent, solution as it changes your soil's pH. It's often used by gardeners growing acid-loving plants such as azaleas, camellias and blueberries.
Option B is to apply a "hydrangea blueing" mixture (liquid or powder) which is made from aluminium sulphate. This is faster acting, but it needs to be reapplied every month or so to keep the hydrangeas nice and blue. I didn't like the sound of that, so I was "yeah, nah" to this method.
This is what our local Mitre 10 store had in stock, so I bought it and applied it to the soil around each plant, then watered it in. The pack comes with a spoon and a guide to how much to use. I've taken a cautious approach and applied half a dose to each plant, and I am sure it is already affecting the flower colour a bit. If it's not that effective, I'll add a bit more later on.
This is the alternative "Option B" product, the aluminium sulfate "blueing" mixture. I didn't buy this and don't intend to, but lots of people prefer a quick fix to a slow fix, and so if you want to turn your pink hydrangeas blue within a few weeks, get some aluminium sulfate.
Finally, in case you're wondering, you can't change the colour of white hydrangeas. In the same soil that's turning my blue hydrangeas into a lilac haze, Pammy's white hydrangeas are looking splendidly healthy, handsome and dazzlingly white.
Those white flowers on a backdrop of deep green leaves really do look nice. This plant is still, of course, a baby, but the plant label says once it is is mature it will be 1.2 metres (4 feet) tall and wide, which is something I am looking forward to enjoying for many years to come.
