Sweetheart hoya plant (Hoya kerrii), also known as Valentine plant or sweetheart wax plant, is a type of Hoya appropriately named for its thick, succulent, heart-shaped leaves. Like other Hoya varieties, sweetheart hoya plant is a stunning, low-maintenance indoor plant.
Water frequency: Every 10 to 14 days.
With its succulent qualities, it's quite adapt at storing water for longish periods of time between waterings. It’s best to allow the moss ball to dry out completely between waterings.
Fill a bowl with room temperature water. Place your kokedama in the water, plant side up. Push the moss ball down so that it is fully submerged and begins to absorb water. Allow soaking for 10-25 minutes, or until fully saturated with water.
Note: We use rainwater. If you use tap water, we recommend letting a bucket of water seat outside for at least 8 hours at daylight while the chlorine evaporates.
Light: Full sun, Part Shade
This plant will need a reasonably lightroom in order to actually grow, although it will still get by even if you pick a shadier spot, very dark places need to be avoided though. Sunlight is acceptable too, so in reality, you could position it almost anywhere in your home or office.
Only a little feeding is required if the plant is small or exists as a single leaf. Twice a year at most. If you have an older plant or that single leaf is throwing out new shoots you can feed a little more. Even then though you don't need to be doing it more than four times a year. The Sweetheart Plant is not a very heavy feeder.
