Planting climbing nasturtium
Climbing nasturtium is usually grown as an annual flower, and are sown directly in the ground in May. It isn’t frost-hardy and will die off in winter. Typically, it sprouts back in spring either from seeds or from tubers.
Here is how to sow nasturtium from seed:
- Soak seeds beforehand for a whole night
- Space seeds 12 inches (30 cm) apart
- Water lightly
Pruning climbing nasturtium and care
It doesn’t need any pruning. If you let the plants self-seed and you’re aiming to cover a wall or arbor, thin the sprouts so that at most a dozen remain. That way, you’ll ensure they’re vigorous enough to climb higher.
As for care, you might need to water a bit if it doesn’t rain for a long time. The vine will bounce back in no time, though, so even if you don’t water it’ll survive.
In fall, when temperatures start dropping, the entire vine starts yellowing. Seeds fall everywhere and will hibernate until the next spring.
At times, you’ll notice caterpillars. These usually come from a white butterfly named Pieris brassicae.
All there is to know about climbing nasturtium
Beautiful climbers, nasturtiums can also be grown in pots like flowing plants. Aphids love this flower, so make the best of it by using it as a decoy to protect nearby flowers.
They are easy to care for and grow and need very little fertilizer. Too much fertilizer would actually reduce blooming.
An interesting fact is that Nasturtium is edible: leaves, seeds. For some species even roots are edible, as in mashua.
