Eucalyptus cultivation environment
Eucalyptus, which is popular as a symbol tree in the garden, grows quickly depending on the varieties planted in the ground, so carefully consider the location of the planting in the ground.
And it is necessary to prun it appropriately and adjust it so that it does not become too large.
Eucalyptus, which has strong potted properties and grows relatively quickly, can be grown a little harshly and left unattended when it is grown compactly in potted plants.
The key to growing eucalyptus on the balcony is to bring it closer to the warm and dry country of origin, Australia.
I prefer a sunny and well-ventilated place, so choose a sunny place on the balcony as well.
It is OK even in a half-shade place. However, it is vulnerable to the cold, so it is a good idea to put it in a warm room in winter.
Points to grow eucalyptus
What about eucalyptus fertilizer and watering?
Eucalyptus planted in the ground is a plant that is resistant to dryness in Australia, the country of origin, so grow it as dry as possible. For the first year after planting, water the leaves when they are wilted and see how they look. It has high vitality, so it can withstand without watering for several days.
Whether or not to give fertilizer depends on the variety, but basically, slow-release fertilizer is recommended so as not to give too much.
eucalyptus grows faster than other plants, so fertilizer is not required for daily care. If the soil on the surface is completely dry, water it. The number of times of watering varies depending on the season. Eucalyptus prefers to be dry, so if you give it too much water to make it over-moist, it will cause root rot.
