Q&A for How to Dry Roses

No, he's talking about the silica, not the roses. The picture doesn't match the text.

Once the petal is dried, it is fragile and pressing it may cause it to disintegrate. Press the rose before drying, in order to get the pressed effect.

You can try, but all of the above methods will cause the rose to discolor. Roses naturally turn a much darker color after they dry.

Yes, you can try, but there may be a lot more discoloration than usual because of the light, and they may disintegrate more quickly. It is better to keep them in a dark, cool place with ventilation. (There will still be discoloration, but it will be less dramatic.)

You don't have to, but if the roses are extremely long - like how most bouquets are - you should have already had the stems trimmed a bit when you got them.

Coat the dried rose with hairspray and it will preserve the rose and make the petals less brittle, so they're less likely to break off.

If you very gently pull away any older, decaying petals on the outside to leave the fresher petals visible prior to drying, all of the above methods will work just fine.
