White radish gone to seed

What’s left of our white radish plant – and it obviously knows it has limited time left…

The white radish is supposed to be a root vegetable. I was told that the leaves are edible as well, but if you harvest too many leaves, how will the plant photosynthesize? Either way, I’ve concluded that this is one of those plants that I don’t have the knack for growing.

I grew four plants from seed several months ago, and thought they would grow well in recycled PET bottles with the narrow tops removed. After all, the white radish is a root vegetable that is narrow and long – as is the recycled bottle. So, for several months, I cared for the plants and watched them grow with what looked like good, healthy leaves. And when I saw what looked like rounded tops just below the soil, I was certain that radishes were growing in there. Finally, when I couldn’t stand it any more, I went digging – and found a radish about the size of a golf ball! Except it wasn’t as round. So, the other plants remained in their pots for several more weeks until we tried pulling out one more, then another, each time finding tiny, joke-worthy roots that you will never see on this blog.

Finally, there was one last plant, and it did something new. It started budding and eventually bloomed with tiny four-petaled off-white flowers. I don’t know if we’ll get seeds from them, but that, essentially, is our sad tale of trying to grow white radishes.

Mongolian giant sunflower plant – still growing

This giant sunflower plant is obviously in the exponential growth stage. It has grown about a metre in less than a month and will soon be towering over the garden swing!

This is rather exciting – our Mongolian giant sunflower plant has now surpassed the height of our garden swing. At today’s measuring-in, the plant is now over 1.7 metres high!

I don’t know whether or not to include the 15 or so centimetres of the plant that I planted below ground because it was rather leggy, but if I do, then it will actually be almost 2 metres high! That means it’s about two-thirds of the way to adulthood.

On the one hand, this is exciting, but on the other, I have to put in a longer support stake because the plant is now higher than the long pole I put in only 3 weeks ago… I think I will end up using one of the bamboo poles that we use for hanging laundry to dry on!

I’ve been using wire ties to hold the plant stem near the supports. What I normally do is secure one end of the tie to the support then loosely drape the tie around the plant stem and attach it to the pole. Those have to be checked every few days because the ties may start cutting into the stem as it grows bigger. You can remove them once the stem hardens up, though, so I usually have only two or three ties on the plant at any one time.

This is what I do to help the sunflower stay upright – a loose loop around the stem until it hardens off and a higher part of it needs supporting. I know it can probably do the job itself, but with my luck, I would end up with a leaning plant…

I wonder whether this plant will grace us with a flower when Christmas comes, or if it will flower before that. Either way, it’s going to be high up!

Attempting to hand-pollinate corn

Close up view of the ripe tassels. I believe the pollen is stored in the dangling brown husk-like things. Just a light tap on the stem will release a light cloud of pollen to the air.

The Red Aztec corn plants have been busy in the last week. The tassels I mentioned earlier have grown not just on the first plant but on four! Some of the plants have just one main tassel while others have between two to five sprigs of tassels.

A search for cobs and silks turned up only one set of possible silks poking out of the top of one of the smaller plants.

Some of the pollen I collected from the Red Aztec corn plants.

The important thing was to seize the opportunity to collect pollen while it was there. You have to wait until you see what look like dangling grains of rice husks, then in my case, I had a big A3 sheet of paper that I lightly creased and held beneath the tassels while I gently tapped the stem. This released the pollen that drifted in a light yellow cloud onto the paper below. I then quickly deposited the precious pollen into a small container that I covered immediately. It’s very windy, and I didn’t want to risk losing any of the pollen.

Corn silks coated with pollen that I collected from 3 different plants.

After collecting the pollen from all available tassels, I shook up the box to mix the pollen before dipping what I thought were silks in it – if it is a hidden cob then I hope it considers itself cross-pollinated! The unused pollen was covered up and stored in the fridge where I’ve been adding on more pollen as it has become available. It hasn’t been on a daily basis because of the frequent rain, but I hope to have enough ready for when the corn is ready to start developing.

This leaf looked like a normal leaf until it started leaning away from the main stem and swelling. You can see the tip of what I hope is a cob poking from the top in the inset. I’m waiting for the silks to appear so I can pollinate them!

A cob appears to be growing now – one of the leaves has pulled away from the main stem with what looks like a possible cob beneath it. There’s no sign of silks, though. When they do appear, I’ll be ready with the pollen!

Year-end sunflowers: not a great idea…

The Mongolian sunflower plant at over a metre high. So far, so good! Let’s hope it keeps growing for a few weeks more!

I had hoped to have sunflowers blooming in the garden when Christmas came around, but it seems that things are conspiring against me. The weather isn’t right, with too much rain at the moment – and too much rain brings the snails out in force. No thanks to that, I’ve gone from rows of little seedlings to rows of nothing or bare stems…

I’ve been through at least three planting cycles already, and have only two plants worth mentioning right now.

The first is the Mongolian giant sunflower. That, thank goodness, has been growing normally. It was a bit touch and go at the start when I transplanted it, because it had a rather leggy stem. I got around that by digging a deeper hole that, when filled, covered most of the leggy stem. From past experience, I know that the plant will eventually grow roots along buried parts of the stem, and that would also help to give additional support for what I hope will be a tall plant.

I didn’t dare get my hopes up too early, though, because all kinds of calamities can befall sunflower plants. As I’ve mentioned before, snails and caterpillars are big foes, as can be heavy rain that pummels young plants to death. So, for initial support, I used a short bamboo stick to tie the plant to.

When the plant exceeded the height of the stick, I found that heavy rain tended to bow the head of the plant down, so I got an ambitiously long 1.8 metre pole to add for support. If I’m lucky, though, the plant will exceed the height of the stick – it is supposed to reach over 12 feet or 3.6 metres (if my calculations are correct) – but with my track record, the odds are it won’t. Anyway, I was cautioned by the seed supplier that strong winds can blow the plants down, so the supports had to go in – and it was lucky they did because we had a couple of storms with winds strong enough to topple a large potted bougainvillea plant.

The first, stunted, Moonwalker sunflower. It is supposed to be about 2 metres high but is less than half a metre high. It does appear to be budding more, as it is supposed to be a multi-bloomer.

So, this baby is about a third of the way there, having grown more than a metre high. My Italian white plants became food for snails, despite my attempts at protecting them. One Moonwalker plant grew to just over a foot high before it budded. All this despite my frequent doses of fertilizers, too! The flower is a joke, but at least is true to the promised pale yellow colour. I hope the reason for the stunted plant is because it was grown from old seed stocks. I have fresher seeds that I will plant, and hope they grow bigger and better.

Oh, and I am now firmly against growing sunflowers in containers – even big pots – because they don’t grow as strongly as the ones grown in the ground. I guess unless they are the miniature varieties, they simply need lots of space for their roots to grow, and when they don’t have that, they don’t grow nicely.

So, I think I shall tone down my planting of sunflowers until the beginning of next year so that I don’t waste any more seeds. The snails will just have to find other food sources!
