How Often to Water A Hoya Krimson Princess
Check the soil once a week and only water it if totally dry. The biggest killer of hoyas is root rot due to sitting in waterlogged soil. After watering tip out any excess water in the saucer under the plant. Avoid overly wet soil, this plant does not like a soggy bottom!
Tip: make sure you do not water the plant until the soil is completely dry all the way down, as the biggest killer of hoyas is root rot. If in doubt, underwater it!
Feed it a balanced fertilizer once a month in spring and summer. They’ll be fine without fertilizer but it can encourage faster growth and support the plant through flowering better.
