Fuss-free Ficus: A Guide to Thriving Ficus Trees in Denver

Ficus is a diverse genus of indoor plants cherished for their lush foliage and air-purifying qualities. Ficus plants have always been popular choices for indoor décor, adding a touch of nature to homes and offices alike. In this guide, we'll explore the dos and don'ts of caring for Ficus plants in our unique climate.

Proper Watering: Finding the Balance
Ficus plants thrive when their watering routine strikes a balance between moisture and allowing the soil to dry slightly between waterings. Our climate demands careful attention to watering. My general advice is to allow potted ficus to gently dry out 50-75% before waterings, using a wooden chopstick or dowel to check the moisture level. 

Use a well-draining potting mix to prevent waterlogging and root rot. 

I have seen many ficus be accidentally underwatered that is because potted ficus tend to have a fairly dense root ball. This makes it hard to get a thorough and even watering. To avoid this I recommend aerating the soil, using a chopstick or dowel at least a few times a year. This will allow water to evenly penetrate your plant's root ball.  

Optimal Lighting Conditions: Emulating Nature Indoors

Light is crucial for ficus to flourish. In our high-altitude environment with abundant sunlight, finding the right balance is essential.  Place your Ficus near a bright, indirect light source. If you have East facing windows your ficus can and will enjoy a few hours of direct sun exposure in the morning, when the sun is not as harsh. 

Variegated varieties should be provided with as much light as possible to ensure their continued variegation. I like to keep my Tineke, Ruby, Altissima, and Shivereana varieties in a west facing window with a sheer curtain drawn. 

Shield the plant from harsh afternoon sun, which can scorch the leaves, specially of variegated ficus species. Rotate the plant periodically to ensure even growth and prevent leaning towards the light.

Fertilization: Nourishing for Growth

Fertilizing your Ficus provides the essential nutrients needed for vibrant growth. Here's how to do it right. I like to feed mine with a balanced, water-soluble fertilizer diluted to 1/2 strength during the growing season, and 1/4 strength during the semi-vegetative season. 

Humidity: Creating a Comfortable Environment

Our arid climate more often than not lacks the humidity many tropical plants enjoy. Boost your Ficus' health with these humidity-enhancing tips. A humidifier is the best and easiest approach, however, if you lack one, placing a container of water near the plant or using a pebble tray will also do the trick. 
Grouping your plants together can create a microclimate with higher humidity levels.

Common Pests: Vigilance and Prevention 


Ficus plants can fall victim to common pests like spider mites, scale insects, and mealybugs. Keep an eye out for signs of infestations. Regularly inspect the undersides of leaves and along stems.
Regularly dusting your plants is an easy way to help dislodge pests before they infest your plants. I also highly recommend using a liquid systemic insecticide to keep bugs from taking a foothold on your trees. 
Quarantine new plants before introducing them to your collection.

Best Soil Type: Nurturing Root Health

Choosing the right soil mix is essential for Ficus plant care. Opt for a well-draining, peat-free potting mix containing at minimum, perlite for drainage. I also like to add chunky horticultural vermiculite to my ficus mix for additional moisture retention and drainage. Periodically adding mycorrhizal fungi to your ficus is another way to ensure a healthy root zone.  

Troubleshooting Common Issues: A Handy Reference

Even with the best care, Ficus plants might face challenges. Here's how to troubleshoot common issues. 
Yellowing Leaves: Overwatering or insufficient light.
Leaf Drop: Sudden temperature changes, drafts, or overwatering. Leaf shed in a bottom to top fashion is indicative of underwatering, as is droopiness.  
Brown Tips: Low humidity or inconsistent watering.

Summary: 
Water when the top 50-75% of soil is dry, adjusting frequency seasonally.

Place Ficus in bright, indirect light, shielding from harsh sun.

Feed with fertilizer diluted to 1/2 strength during the growing season, and 1/4 strength during the semi-vegetative season. 

Increase humidity through the use of a humidifier and or pebble trays.

Watch for pests, frequently dust the leaves, and use a liquid systemic insecticide to head off any pest issues. 

Choose well-draining soil mix with additives like perlite, and chunky vermiculite. 

Aerate the soil frequently to ensure proper water absorption.

Winter Plant Care In Colorado

Winter Care for Plants in Colorado  Photo by Annie Spratt on Unsplash  One of the questions I receive from people most often lately is, "how do I care for my plants in the winter?" I decided that this was a good first topic to get the blog started! The information I am going to share with you here is based on my personal experience and research over the years.  Why is plant care more difficult in the fall/winter months?  I am not going to fully disagree with the fact that taking care of plants in the winter can be a bit challenging, but I am going to say that I think the problem is often times blown out of proportion. The main challenges in Colorado come from shorter days which leads to less light, colder temperatures, and even less humidity than we normally deal with.  First, it is important to address the topic of dormancy in house plants. In simple terms think of dormancy in house plants as being equivalent to an animal's hibernation season. This is a time of rest for

My plant story Hey there! My name is Victor and I am the owner of The Plant Room. We are a small Denver, CO based latinx plant shop. My love and appreciation for plants began when I was a child as I grew up in a house surrounded by them. My mom, to his day has the most amazing way with plants and I spent my childhood watching her resuscitate plants that she found in the trash, or half dead ones that people gave to her at work. I was always fascinated by my mother's ability to bring things that I was sure were dead back to life. To this day some of those second life plants still hang around her house.  My mom saw my childhood interest and began to share what she knew with me. She instilled in me that most plants could easily be taken care of if you started with and focused on the basics: water, soil, light, feeding. Of course, taking care of plants can be a very intense, time consuming, and sometimes expensive process but it doesn't have to necessarily be. The main thing my mom

Alocasia Care Guide

Introduction to Alocasia: Alocasia plants, commonly known as Elephant's Ears, are a stunning genus of rhizomatous or tuberous tropical foliage plants belonging to the Araceae family. Native to Southeast Asia and the Pacific Islands, they are loved for their large, often textured leaves and unique patterns. There are about 90 accepted Alocasia varieties many of which are in constant rotation around the shop!  Caring for Alocasia in Denver: Proper Watering: Alocasia prefer consistently moist soil, that is never waterlogged. Water thoroughly when the top inch of soil feels dry, during the growing season. Usually in the fall and winter I prefer to let them GENTLY dry out throughout the entire pot. When in doubt, a good rule is to allow the plant to dry out at least 50% of the way. Like I always say, more often than not, too dry is preferable to too wet.  Use room temperature water and thoroughly water the soil directly, avoiding the leaves to prevent fungal issues. Using cold water c
