From my research and personal experience there is some disagreement on the level of difficulty in cultivating Tulsi. All sources do agree though that these plants like it hot and can be difficult to grow in a temperate climate. However, with a bit of love and energy they have been known to flourish even in unfamiliar climates.
Here is the plan of action I came up with for planting my Tulsi seeds:
1. In the late Spring/early Summer, create or buy a rich, vegan-organic potting mix.
2. Fill a tray or small seedling pots with this mix, and lightly press seeds into the soil. (If you have some around, spray EM on the seeds first to give them a boost.) One seed per six inches of soil, or one seed per pot will do. If you can still see the seeds, gently sprinkle a small bit of dirt over the top of them.
3. Keep the Tulsi seeds moist and warm until they germinate, which can take anywhere from one to six weeks.
4. Like all basils, Tulsi will branch out when pruned correctly. After the first six sets of leaves appear, pinch off the top set of leaves. This action tells the plant to put its energy into branching out instead of reaching higher.
5. Water your plant as needed, but do not be afraid to let the soil dry in-between watering. Tulsi likes well draining soil and will not do well if left sitting in water.
6. If your plant starts to go to flower, you can either pinch off all the flower tips (so that the plant will put its energy back into growing) or you can allow part of the plant to flower and then go to seed – either way it is better not to let the entire plant go to flower.
However you decide to enjoy your Tulsi, I wish you the best of luck with your health, growing and tea brewing!
