|Do I need special fertilizer, or lime or what???|
|Gooseberries are usually fairly easy to please, as long as they are in full sun to partial shade, have at least average soil fertility and the pH is near neutral. You might want to run some basic soil tests and see if anything unusual is going on there.
Your county extension should be able to help you with the tests and interpreting the results.
You might also want to make sure that your pruning is done to maximize fruiting. Each year, remove the new growth leaving only about three of the new shoots; also remove all four year old (or older) shoots. This way you will always have a supply of one year old, two year old and three year old shoots. The two and three year old shoots bear the most.
Other than that, the plants require a few years to settle in a bear a good crop, so if your plants are new it may simply be a matter of patience.
