A glass of water on a windowsill does what most beginners think requires a greenhouse, a heat mat, and a seed-starting kit.
It sprouts fruit seeds where you can watch every root emerge in real time.
– Avocado — suspend the pit with toothpicks, flat end down, roots crack through the base in two to six weeks
– Lemon — peel the seed coat for faster germination, roots in one to two weeks
– Pomegranate — fresh seeds from the fruit germinate in shallow water within two weeks
– Cherry — needs 60 days in the fridge first, then roots emerge in water fast
– Fig — stem cuttings root more reliably than seeds, place a six-inch cutting in a tall glass
Apple, peach, plum, grape, and hazel all germinate the same way — extract the seed, cold-stratify in the fridge, then transfer to water.
The windowsill is the nursery. The glass is the greenhouse.
