Alpine Strawberries, Poor Fruiting

I have been growing Alpine strawberries in a pot for a year now and can only seem to have one fruit ripe at a time. I have removed several plants from the pot to give the plant more room. I am getting plenty of blossoms and the fruit starts to grow and then stops growing and dies. How deep should the pot be and how much room does the plant need to have the fruit ripen? How wide apart should the plants be?

A standard sized pot should work fine and if the pot is very large, even the azalea pot shape will do well. The plants should be about 15 centimeters (six inches) apart.
There may be three other problems. You may not be giving the plants enough light for them to make sufficient food to sustain the fruit. You may let the plants dry out too much which would make them abort the fruits. Or there are no fertilized seeds on the fruit, in which case the plant would abort the fruits as well. Brushing a soft paint brush over the flower should solve that problem.
