If a growth started, it is time to water often, as the rule of thumb is to water well during growth and blooming, and to let your Dens get very dry before watering, when not in growth or bloom.

As to repotting, the absolute best time to repot is when the new growth is just starting new roots. Dens start rooting when the new growth is a few inches long, which is coming up very soon now. So, my recommendation is to repot now or any time from now until the rooting starts, which doesn't really give you a lot of time to find some mix, if you have to search for it, like we do up here in Prescott. The recommendation to repot in spring is based on many orchids starting growth in spring, but it is much better to look at the plant to know when growth is starting, not to go by seasons.
