Growing a greek tomato tree is not for beginners. One of the most important things that you will need to take care of is the soil. You should consider getting a soil mix that's right for tomatoes and if you want to be extra careful, add in some compost or fertilizer.
How to germinate
The first step is to get the seeds and soak them in water for a few hours.
The first thing that you want to do is take the greek tomato seed and soak it in water. Place the seed on some paper towels or a damp cloth so that it can absorb all of the water.
After 24 hours, take the seed out of the water and let it dry off for about 30 minutes before placing it back on some paper towels or a damp cloth (don't worry, this shouldn't take too long because seeds like these are usually quite moist already).
After a few days, you should start seeing some roots beginning to grow.
Transfer seeds from the paper towel to potting soil.
