Can lime and fertilizer be applied at the same time? If lime is applied first how long until fertilizer be applied. Will these applications effect seed germination? Assuming fertilizer is NOT weed control.

Lime can be applied anytime that the soil is not frozen.
In most cases though, we recommend fall applications for fertilizer and overseeding, and at rates suggested by a soil test. Excessive nitrogen applications in spring and summer can increase disease problems and reduce stress tolerance.
Spring seeding is more difficult than fall due to weed competition like crabgrass or Japanese stiltgrass, which are germinating around the same time.
If you must seed this spring, you could use a seed-starting fertilizer.
They could be applied at the same time, though it is best to apply lime at rates suggested when soil is analyzed.
