Tropical Fruit Discussion / guavas, water and low rate of germination
« on: July 20, 2013, 11:00:34 AM »
How do I know if I'm following good methods to germinate guava (Psidium guajava) and Pisidium cattleianum? I'm getting a low percentage of germination, every day I keep the substrate (compost or vermicompost) moist, but how wet should it be? The room temperature is between 19º C and 25º C.
How do I know if I'm doing overwater? Do I have to let the soil dry out sometimes?
I water with a bottle that strip droplets, but it is true that sometimes i am watering 2 times per day if I see the soil drying out.
The first batch of strawberry guava seeds planted in compost (vegetable) had high (for what I know) percentage of germination and survival (approx half), the second batch planted in vermicompost, only 12 of 60 in 4 months, and not likely to germinate any more, although I have noticed that some continue to appear after 4 months in vegetal compost.
On the guava (Psidium guajava), germinate only one sixth (15% approx) or less; maybe I am over watering? the compost will be bad? there was a batch planted in compost with many "little rocks" (with a few pebbles to put in the compost to aerate the soil) that was not very successful.
What would you do?
