Don't be fooled by appearances! If its fruits, with their bumps and thick bark, look tough, Citrus medica is a great sensitivist. Although the citron tree originated in Nepal and Myanmar, this member of the Rutaceae family can't stand the cold or the heat.
How to recognize Citrus medica?
Citrus medica is a shrub that grows up to four meters high and two meters wide in the open. In pots, the citron tree retains its irregular, bushy habit without exceeding two meters in height.
The trunk and branches have grey bark. But only the twigs bear thorns in the leaf axils.
These can be lanceolate or elongated, up to 20 centimetres long. The leaf blades are slightly glossy green with a serrated margin.
In late spring, purplish-pink buds appear. These then give rise to white, star-shaped flowers. Each flower has five petals and up to 60 stamens! The blossoms have the characteristic sweet smell of citrus.
While the flowers resemble those of Citrus x microcarpa (Citrus x microcarpa), the fruit is very different. The citron is between ten and 20 centimetres long. Its thick, fragrant skin turns from green to orange-yellow as it ripens. It is irregular, rough and bumpy. The shape of the citron varies according to variety. In the typical species, the fruit is oval. By contrast, in the digitized Citrus medica, known as Buddha's hand, the fruit is segmented and looks like a hand or octopus.
Citrus medica is not poisonous, andits flesh is edible, though not highly prized. Pale yellow or greenish, it is acidic and not very juicy. Cooks, on the other hand, love the zest, which is fragrant and rich in flavor.
Our maintenance tips
Citrus medica is one of the few citrus fruits that can be grown indoors. In summer, however, it can be enjoyed on a terrace or balcony to soak up the sun.
Watering
Allow the substrate to dry on the surface (at least three centimetres) between waterings. Water the root ball of your Citrus medica with non-calcareous water at room temperature.
Don't forget to empty any stagnant water from the dish or pot. It will rot the roots.
Spray
Citrus medica come from tropical regions. They appreciate high humidity. To recreate it, spray the foliage with non-calcareous water at room temperature.
Repotting
Every spring, repot your Citrus medica to give it more space.
When roots protrude from the pot or are visible on the surface, it's time to repot!
To prepare your Citrus medica for repotting, soak the root ball. Then gently loosen the root ball.
Choose a terracotta pot or a wooden tub. Both materials encourage water evaporation and reduce the risk of over-watering. Make sure the container is perforated to allow water to drain away.
At the bottom, place a bed of clay balls or gravel to facilitate drainage.
Top up with a rich substrate, such as special citrus or planting soil. You can make your own mixture with :
- one-third planting soil
- one-third garden soil
- pozzolan.
Place your shrub in the center. The surface of the rootball should be two centimetres below the rim of the pot. Fill with substrate and tamp to eliminate air bubbles. When planting, do not bury the collar.
Fertilization
To promote the growth of your Citrus medica, apply fertilizer in spring and summer.
Citrus medica are greedy plants. They need to be fertilized. Feed yours with a special liquid or granulated citrus fertilizer.
Cleaning
Clean the leaves with a clean wet sponge. This removes dust and improves photosynthesis. It's also a way of preventing mite infestations.
Prune
Size is not essential. It only helps to control shape and development and improves fruiting. When pruning, always use clean, sharp pruning shears.
Citrus trees flower and fruit on the year's wood. To maintain the compact, rounded shape of your shrub, remove dead branches and shoots growing along the trunk. You can also aerate the center by removing some shoots that have already borne fruit in previous years.
If you want to improve your harvest, you can also carry out a fruiting pruning operation: one month after the appearance of a new shoot, prune it back to a height of 20 centimetres.
Pinch
Pinch your Citrus medica during its growing season.
To give your plant a compact habit, pinch back young shoots. This improves branching.
Plantation
When the risk of frost has passed, it's time to plant.
Find them a place sheltered from the wind and isolated from other plants. Citrus plants have shallow roots and don't like to share their space.
Dig a hole 70 centimetres wide and 1 metre in diameter. While you're at it, soak the root ball.
Plant the plant in the middle, with the top of the rootball level with the ground. Take care not to bury the collar.
Citrus medica plants thrive in light, well-drained, rich soil. When filling in, add potting soil or citrus soil to your garden soil. Tamp and water.
