Fertilizer

Can you use both Boost and Quality Fertilizer at the same time?1

I'm afraid I can't confirm this conclusively, but I believe so-- you'll find that when you add peat, for instance, the prepared square has two little signs for both growth time and quality, as this little example shows.

I've noticed that throwing down peat, then quality fertilizer II makes the star gold, while leaving the "copper" hour glass.

I suspect that if you added the boost fertilizer II, you'd get a gold hour glass as well.

In other words, throw a boost II on a tile and then a quality II and I expect you'd get the effects of both, as indicated by the corresponding little signs on the plot.

Yes you can.

To expand on mlemmlemmlem's answer, each 'field' whether it's the plain, with sticks or with the vine trellis has two fertilization states, the crop quality and the growth speed. Apart from peat, which is a bronze star on both, the other fertilizers give you either one. That way you can either get crops fast with the boost fertilizer or improve the quality (more crops, better stars, less waste, more seeds) with the quality fertilizer, or you can do both, though that's expensive, particularly later on as you need 20 peat plus 1-2 energy elixirs and either 1 growth enhancers or 2 flavour enhancers to fertilize 10 fields.
