Hoya lacunosa (Silver) Care Detail

Light Requirements:

  • While Hoya plants, in general, may thrive in a variety of lighting situations, bright, indirect light is preferable for a Hoya lacunosa Louisa's Silver
  • Hoya lacunosa Louisa's Silver thrives in the partial or full shade outside, but make sure any direct sunlight isn’t too severe. The delicate leaves of this plant should only be exposed to early morning sunlight. 
  • Excessive sunlight can cause leaf burn, so ensure that your Hoya is nowhere near bright direct sunlight. 
  • The plant has a lesser chance of flowering when indoors. However, the plant will put out blooms given adequate light and fertilization during the growing season. 
  • During the winter season, you can place your Hoya under warm artificial light so that it remains healthy during its dormancy phase.

Temperature Requirements:

  • As with other hoyas, the Hoya lacunosa Louisa's Silver thrives best in a temperature range of 60-85 degrees Fahrenheit. 
  • If you live in a temperate zone, the Hoya lacunosa Louisa's Silver can grow well outside as well. 
  • During the winter months, ensure your plant is placed in a warm area of your home. You can use heating pads and warm lights for this. 
  • Additionally, use a pebble tray and warm water to keep your Hoya lacunosa’s soil warm and cozy. 
  • The kitchen and bathroom are two places within a house that remain warm during the winter. You can place your Hoya there.

Humidity Requirements:

  • All hoyas thrive in high humidity levels. Humidity ranges of 60-80% are best for Hoya Lacunosa Louisa's Silver, although it can still grow well in the 55% range. 
  • The plant benefits from periodic misting of its leaves during the summer months. You can use a small humidifier or a pebble tray to maintain humidity levels. 
  • During the winter months, placing your plant in the bathroom can provide it with much-needed heat and humidity.

Watering Requirements:

  • Hoya lacunosa Louisa's Silver is particularly susceptible to root rot due to overwatering. 
  • Only water it when the top two inches of soil is dry. You can check this by inserting your index finger into the potting soil. If the top joint of your finger comes out wet, then you should not water it. However, if it’s dry, it is time to water your Hoya. 
  • Stick to a flexible watering schedule during the summer months. It might need more water, and the soil will dry out faster since the summer season is the active growing phase for Hoya lacunosa (Silver) 
  • It will not require much watering during the winter.

Soil Requirements:

  • In general, epiphytes do not need much soil in the wild because they take in water and nutrients from the air with their exposed root system. 
  • Soil mixes need to replicate somewhat of their natural habitat. You will require well-draining soil that is not compact and provides aeration to the roots. 
  • Orchid mixes, succulent mixes or an African Violet mix will be the best choice.

Fertilizing Requirements:

  • In the cooler, darker months, the Hoya lacunosa Louisa's Silver will benefit from an evenly balanced houseplant fertilizer (such as a “2-2-2” recipe) diluted to half-strength once every six weeks or so. 
  • This schedule could be increased to once or twice a month during the active growth season. 
  • Since the Hoya lacunosa Louisa's Silver does not put out flowers, you can keep using a fertilizer designed for foliage plants in the ratio mentioned above.
