Every cup of green, black, white, or oolong tea starts with the same plant: Camellia sinensis. That makes this species especially rewarding to grow yourself. You start with a modest seed and eventually get an evergreen shrub with glossy leaves, small white flowers, and most importantly: leaves from which real tea is made.
The seeds of Camellia sinensis have a tough outer shell. So first place them in lukewarm water for 24 to 48 hours.
The goal is simple: allow the seed to hydrate properly before it goes into the soil. Use clean water and sow the seeds immediately after soaking. Do not let them dry out again afterward.
The tea plant prefers an airy, slightly acidic growing medium. For sowing, you can use a mix such as this:
You can also keep it simpler with approximately 70% coco coir and 30% perlite. Above all, make sure the substrate can retain moisture without staying permanently wet.
Fill the Germie Modular Growing Kit or small pots measuring approximately 9 to 11 cm with the moist seed-starting mix.
Plant the seeds approximately 1 to 2 cm deep. Cover them with a thin layer of substrate and press it down gently. A transparent cover or plastic film helps retain moisture around the seeds.
Ventilate briefly every day. This keeps the humidity high without creating a greenhouse for mold.
A temperature of approximately 20°C to 25°C is ideal for germination. Consistent warmth is especially important. A heat mat can help when the temperature indoors fluctuates.
Give the seed tray plenty of light, but avoid strong direct sunlight. At this stage, the combination of warmth and moisture is more important than maximum light intensity.
Camellia sinensis takes its time. The first seedlings usually appear within 4 to 12 weeks, but germination can be quite uneven.
That means you should not start over with everything after four weeks. As long as the substrate remains moist and the seeds are healthy, simply give them time.
When the first leaves appear, provide more bright light. Keep the young plants protected from strong afternoon sun and prevent the seed-starting medium from drying out.
After the initial growth phase, you can repot the plant when the root system is sufficiently developed. Use a pot with drainage and an airy, slightly acidic substrate.
Camellia sinensis prefers evenly moist soil. Therefore, do not let the plant dry out for extended periods, but also prevent the roots from remaining constantly wet.
A bright spot with indirect light or partial shade works well. As the plant becomes stronger, it can tolerate more sun. However, protect young plants from extreme heat and drying out.
That is the fun part, but also the part that requires patience. A young tea plant must grow first before you can harvest seriously.
The leaves and young shoots can later be used to make tea. The difference between green, black, white, and oolong tea does not lie in different plants, but mainly in the timing of the harvest and the processing of the leaves.
Growing a tea plant is really like having a small piece of tea history in your own home. You see the seed germinate, the first leaves appear, and a shrub slowly develops from which your tea can eventually come. The kettle only comes into the picture much later. 🍵🌿
