  1. 70-80°F ideal for growth, but Morning Glories tolerate 60-85°F.
  2. 🌞🔥 Protect from heat and frost to prevent leaf scorch and stunting.
  3. Consistent temperature ensures continuous Morning Glory blooms.


Morning Glories, with their vibrant trumpets, are warmth's best friends. Temperature is key to their well-being.

🌡️ Setting the Scene for Success

The perfect temperature range for Morning Glories is between 70-80°F (21-27°C). This is when they truly flourish.

🔥 When Things Heat Up

When your Morning Glory's leaves look like they've had a rough day at the beach, it's too hot. Leaf scorch and wilting are your cues to dial down the heat.

❄️ Chilly Challenges

Cold stress turns Morning Glories into drama queens. Look for yellowing leaves and stunted growth as signs that your plant is not amused by the chill.

🌞 The Sun's Embrace

🛡️ Avoiding the Scorch

Direct sunlight can turn your Morning Glory into a crispy critter. Relocate plants to areas with filtered light if they start showing signs of stress, like faded leaves or brown tips. No room to move? A sheer curtain or shade cloth can be your plant's knight against the sun's fiery lance. Keep a vigilant eye; early detection is key to preventing a full-blown leaf scorch.

❄️ Frosty Mornings

🚫 Dodging the Chill

While Morning Glories can handle a bit of cold, they're not fans of the freeze. Insulate your plants or move them to a warmer spot when the thermometer dips too low. Watch for signs of cold stress like wilting or discoloration. Remember, it's not just about survival; it's about maintaining a comfortable zone for those vibrant blooms to keep on showing up.

In the end, keeping your Morning Glory blooming is all about hitting that temperature sweet spot. 65°F is the magic number, but don't sweat if your thermometer wavers a bit. These resilient climbers can handle a range from 60-85°F (15-29°C), so they're more forgiving than your high school gym teacher. Just remember, when the mercury climbs, your plant's not trying to get a tan. Protect it from scorching with some shade, and keep it hydrated—think of water like a cool drink on a hot day.

As the sun dips and the chill sets in, don't let your Morning Glory shiver in the cold. Avoid frost like you'd sidestep a puddle in suede shoes. If you're in a pinch, a frost cloth can be a Morning Glory's cozy blanket. And, if you're in a tropical paradise where frost is just a myth, consider yourself lucky—your Morning Glory is living the dream.

So, monitor the temperature, shield your plant from extremes, and you'll be rewarded with a cascade of blooms that'll make your neighbors peek over the fence. Keep it too hot or too cold, and you'll be the one throwing a fit, not just your Morning Glory. Remember, these plants are not just a splash of color in your garden; they're a testament to your care. Treat them right, and they'll return the favor, morning after morning.
