.With its vivid, heart-shaped leaves and painterly splashes of color, the heart of Jesus plant (also known as Caladium bicolor) is one of the most eye-catching houseplants you can bring home. Whether in bright pinks, deep reds, white veins, or lime greens, every leaf looks like a living piece of art. And even better? It is compact, non-demanding in space, and surprisingly expressive.
If you are thinking of bringing a heart of Jesus plant into your home, you are not alone — this tropical beauty is a favorite among indoor gardeners for a reason. It adds an instant “wow” factor to your space and changes throughout the season, making it feel like a living, breathing part of your decor.
Despite its showy look, the heart of Jesus plant isn’t difficult to grow. Yes, it has preferences (and opinions!), but once you understand what it needs, caring for it becomes both simple and rewarding. So, today we are going to discuss everything from light placement to watering — all step by step.
When it comes to indoor caladiums, light is key — but it is also one of the most common stumbling blocks for new plant parents. The heart of Jesus plant loves bright, indirect light. Think “well-lit but not sunburned.”
Avoid direct sunlight, especially during mid-day or early afternoon hours. Harsh rays can scorch those delicate leaves, leaving behind unsightly brown patches or faded spots. On the flip side, too little light, and you will notice slow growth and dull colors.
Best spots to try:
Near an east-facing window (morning light is gentle)
A few feet from a north-facing window
Rooms with sheer curtains that filter the light
If your room tends to be on the dim side, consider using a grow light — but don’t overdo it. A few extra hours of soft supplemental light can make a big difference, especially in winter.
Light Tip: Rotate the pot every 1–2 weeks to prevent your plant from leaning toward the light source. This keeps growth even and symmetrical — a quick fix that goes a long way.
The heart of Jesus plant doesn’t like extremes. It prefers soil that’s consistently moist, but not soggy. Watering too much or too little can quickly lead to trouble, especially with such sensitive roots.
Here is how to get it just right:
Frequency: Water when the top 1–2 inches (about 2–3 cm) of soil feel dry to the touch.
Method: Water slowly until it starts to drain from the bottom. Never let the pot sit in standing water.
Water type: Use room-temperature, filtered or rainwater when possible. Tap water with chlorine or fluoride can cause leaf edges to crisp up.
Common watering problems
Symptom | Possible Cause |
Yellowing leaves | Overwatering |
Dry, crispy edges | Underwatering or dry air |
Mushy stems | Root rot from excess moisture |
Water Tip: If you are ever unsure, check the soil manually or use a moisture meter. It’s better to under-water slightly than drown the plant.
The heart of Jesus plant may look delicate, but it is a true tropical — and that means it thrives when the climate is just right. To keep those bright, colorful leaves healthy, your plant needs warm temperatures and high humidity, especially if it lives indoors year-round.
Ideal conditions to aim for:
Temperature: 20–27°C (68–80°F) is the sweet spot. Avoid placing the plant near drafty windows, air conditioners, or radiators.
Humidity: 50–70% is best, especially during winter heating season when indoor air tends to dry out.
How to boost humidity (without creating a fungal mess):
Use a humidifier: This is the easiest and most consistent method.
Set up a pebble tray: Fill a tray with pebbles and water, then place the pot on top (just above the water line).
Group your plants: Plants naturally increase humidity around them, so cluster them together like a tropical mini-forest.
But here you should remember one important thing: skip the misting — it might seem helpful, but in dry indoor air, it evaporates too fast and can encourage fungal issues if water sits on the leaves. At the same time, if the leaves begin to curl inward, your plant is likely too dry. It’s a common distress signal and your cue to raise the humidity ASAP.
While those bold, heart-shaped leaves get all the attention, don’t overlook what’s going on below the surface. Caladiums grow from tubers, so they need well-draining, breathable soil to stay healthy and rot-free. The perfect potting mix includes:
2 parts peat moss or coco coir
1 part perlite
1 part orchid bark or fine pine bark
(Optional) A handful of horticultural charcoal — this helps absorb excess moisture and prevents root rot.
Make sure to use a pot with drainage holes — this is non-negotiable. Water must be able to flow out freely to avoid waterlogging the tuber.
When to repot?
Every 1–2 years
Or when the tuber starts pushing upward out of the soil
Mini tip: When repotting, gently loosen the soil around the tuber and inspect it. Healthy ones are firm and plump. If you spot any mushy or discolored parts, trim them carefully with clean tools.
Here is something that surprises many first-time Caladium owners: it disappears — and that’s completely normal.
When temperatures drop or daylight lessens, the heart of Jesus plant naturally enters dormancy. Leaves turn yellow, droop, and eventually fall off. Don’t assume you’ve failed — it is just resting.
Dormancy signs:
Leaf loss (gradual or sudden)
Yellowing foliage
Slowed or halted growth
What to do in this case: stop fertilizing and reduce watering; store the tuber (still in soil or removed) in a warm, dry place around 16–18°C (60–65°F). Then once spring arrives and temperatures rise, replant (if stored bare) or resume watering and watch for new growth.

Caladiums are not heavy feeders, but they do appreciate a little nutritional boost — especially during their active growing season. The key? Consistency and moderation.
When and how to fertilize:
Frequency: Once every 2–4 weeks from spring through late summer.
Type: Choose a balanced liquid fertilizer formulated for foliage plants, preferably low in nitrogen (look for an N-P-K ratio like 5-10-10 or 10-10-10).
Seasonal pause: Do not fertilize during dormancy — feeding a sleeping plant can lead to root damage and rot.
Pro tip: Always water your Caladium first, then apply diluted fertilizer. Feeding dry soil can burn the roots and stress the plant. A light touch is better than overfeeding.
Even with the best intentions, things can go wrong — but most Caladium issues are easy to identify and fix if you know what to look for.
Symptom | Likely Cause | Solution |
Faded or washed-out leaves | Not enough light | Move to a brighter, indirect light source |
Brown patches or crispy edges | Hard water or dry air | Use filtered water and raise humidity |
No new growth | Dormancy or low temps | Check the season — wait for spring |
Droopy, soft stems | Overwatering | Let soil dry slightly and improve drainage |
Important reminder: Resist the urge to prune healthy green leaves, even if they look a bit wild — they are still feeding the tuber below. Let them die back naturally when the plant enters dormancy.
The heart of Jesus plant may have a reputation for being a bit of a diva — but once you learn its rhythm, it is surprisingly easy to care for. It asks for warmth, gentle moisture, and a bit of patience. In return, it delivers lush, heart-shaped leaves that look like painted masterpieces.
So if you are willing to pay attention and give it the right setting, this tropical stunner will reward you again and again — sending up fresh leaves when you least expect it. Just don’t be discouraged by the plant’s diva reputation, tune in to its needs, and you’ll be rewarded with bright color leaves on your windowsill.
