Prepare and Care for Overwintering Interiorscapes
Posted: September 20, 2021

Even though interiorscapes reside year-round in relatively temperature-controlled indoor climates, overwintering plants can become stressed by fluctuating temperatures, excessively hot or dry air, less light from shorter days, and seasonal pests. Keep interiorscapes thriving by modifying their care during the cooler months of the year.
It all boils down to: Water.
Contrary to intuition, winter poses far more complexity to keeping interiorscapes correctly moist than any other season. Depending on many factors including the consistency of the temperature maintained around the plants, the humidity of the air, the amount of evaporation and transpiration, and the quantity of light exposure, interiorscapes suffering from too little or too much water are easily susceptible to infections or infestations.
Temperature and humidity fluctuations, either too hot or too cold, near interiorscapes are the most common adversaries to maintaining healthy moisture content. In addition to hardening or moving plants near exterior doorways where freezing air frequently enters, redirect or block HVAC vents blowing directly on plants as well as heating (or cooling) elements nearby. Plants prefer temperature and humidity consistency above all else. Although plants enjoy cooler temperatures at night, ensure a minimum of 55 degrees at night for maximum health.
Not to be underestimated is moisture loss from evaporation (from the soil) and transpiration (through the leaves). Interiorscapes comprised of plants in small containers or planters with low soil mass to root ratio have the hardest time with evaporation stress. Green walls and similar installations require greater attention to detail than do installations in large planters. Likewise, plants with broad or soft leaves transpire more quickly than do small or waxy leaved plants so understanding what kind of plants comprise your installations is essential for interiorscape health.
Complicating the mix is the natural transition of light (as well as heat) exposure throughout the winter months. Plants gradually phase through a dormant or semi-dormant cycle which impacts watering (as well as fertilizing) schedules to the extent that any routine must be monitored and adjusted weekly if not daily.
Our2Sense: Measure soil moisture.
At a minimum we recommend deploying manual moisture meters in as many containers or installations as needed to adequately sample and measure the moisture in various similar planters. Checking the meters daily will go the longest way to ensuring healthy overwintering interiorscapes.
For large, commercial, or specialized installations, a moisture meter system which monitors (measures, tracks, alerts, and even regulates) is ideal. While these systems are more expensive, costs are no longer prohibitive to the individual or private client now.
