Top 20 Heat-Tolerant Plants: Perfect for outdoor gardens

I categorised my garden into four parts: edibles, house-need Herbs, home decor plants indoor & outdoor, my favourite plant collection (a combination of plants), and experimental plants.

Edible and house-needed herbs are mostly veggies, fruit trees in my ground garden, flowering plants in the ground and containers, and herbs in containers. I grow these plants for my needs so I can adopt heat-tolerant plants and do extra work to protect them from heat-tolerant plants. It’s a combination of plants.

Home decor plants are mostly shade-loving plants, and few of them are chosen based on the spot’s sunlight and I’ve options to choose heat-tolerant plants.

My favourite collection of plants is mostly heat-tolerant and drought-tolerant because I need my little green babies to live for long years so I mostly choose heat-tolerant plants. And it’s a combination of foliage.

The experimental plants are not my personal choice, it’s for my research purpose to give you some real facts. How is it doing in hot, cold, windy, rainy weather? These plants are used for my potting mix experiments, fertiliser experiments, and watering experiments mostly these are grown from seeds and saplings.

So now I am going to give some hacks and tips to choose heat-tolerant plants that are combined with my experience and knowledge from my fellow gardeners.

Challenges of container gardening in hot climates

Being a plant enthusiast and living in heat regions is not a great combo. Of course, you have got the perks of sunlight for most of the year. Plants gonna thrive. But growing plants in hot weather is quite challenging. Frequent watering, quick drying soil, leaf scorches. Sometimes your seedlings do not make it.

I saw my annuals burned in my Indian summer. even last September I ‘didn’t see any good signs of rain but facing 30 degrees Celsius of heat every day, of course, I might get surprised but November or December rains.

Initially, I thought, placing plants in semi-shaded areas, and using shade nets would help. But the reason is not only sunlight, extreme heat waves and less humidity also affect the plants.

It doesn’t mean I stopped growing plants; I took safety precautions like setting up a greenhouse for edible plants. And switch to shade-loving plants. Adjusting my Watering techniques. These are okay for me because it’s my work and I’m passionate about this.

But if you just want to grow plants as a hobby you can’t do these chores for a long time. But you can adopt heat-tolerant plants for your hot weather.

Importance of choosing heat-tolerant plants

If you live in extremely hot weather countries, it’s better to adopt heat-tolerant plants. So, you can have a peaceful gardening experience. You can grow various plants and experiment with various species. But as a beginner or a hobby gardener try to keep it shuttle.

WHY HEAT-TOLERANT PLANTS ARE IDEAL FOR CONTAINER GARDENING

When you’re walking through your Container Gardening in your Hot regions. You might see some leaves are brown, some plants struggle to thrive, and dry soils and your seedlings struggle to make it. Maybe these are the reasons behind those issues.

Heat Stress and its Effects

Exposure to high temperatures and insufficient watering is a barrier to your growth. But if you think I’m watering well my plants are in semi-shade. Just recheck these things too.

Smaller soil volume the Pot holds only a limited amount of soil, but if you’re not noticing the soil compaction or less soil than the ideal limit it also leads to an issue of water retention less soil holds less water and nutrition. Fill up the soil till the plants’ roots are fully covered and cover half of the stem below you see any leaves or fruit anything.
Water evaporation in hot weather the water inside the pots also dries quickly leading to wilted leaves and prone. Using a water-retention soil mix and adding mulch is helpful.

Key features of heat-tolerant plants

Heat-tolerant plants are adapted to withstand hot weather thing makes the plants ideal for hot regions.

Drought Resistance Most heat-tolerant plants preserve water in themselves their structure of waxy leaves, reduced leaf size and thick foliage designed to survive in drought weather.
Deep-rooted system of heat-tolerant plants can access water in every part of the soil more efficiently. So, the possibility of dry soil is less.
Succulents are naturally structured to store water in their leaves and stems to survive in extremely hot weather. It’s the best choice for hot regions.
Water efficiency these plants naturally absorb water sparingly to survive in hot weather.

FACTORS TO CONSIDER WHEN CHOOSING HEAT-TOLERANT PLANTS

There are some different kinds of heat-tolerant plants., they’ve different heat-tolerance levels and watering needs just read and know about those kinds and choose a plant that is exactly suited for your location.

Sun-Exposure

Full-sun most of the heat-tolerant plants come under this category. This plant thrives in 6+ hours of sunlight daily. Plants like cacti succulents and Mediterranean herbs have come under these.
Partial-shade plants are not sun-loving but heat-tolerated you can place these plants where you can receive morning and evening sunlight, these plants are less tolerable to the high temperature of afternoons. You can move them in partial shade on hot afternoons.

Watering Needs

Drought-tolerant plants like cacti succulents, and grasses are natural water savers. They store water inside them to survive extremely hot weather. If you want to place containers outdoors these drought-tolerant varieties are good choices. They also don’t frequent watering and survive hot weather.
Moisture-loving plants Some of the tropical species’ heat-tolerant plants are moisture-loving they want their soil to be moisture retention. They need regular watering and make sure these varieties are in pots with drainage holes.

These are some common facts but if you see signs like wilting, dry soil and leaves scorches you need to take some care as I mentioned below.

Deep watering is a method in which you should water slowly and deeply so the plant can absorb water thoroughly. You can use a Hose nozzle to water deeply.
Mulching is a process to keep the soil moisture and protect it from water evaporation.
Water retention is a method of adding more moisture retention soil mix into the potting soil.
Shade Cloth might be helpful if you place container plants in open spaces that get too much heat and direct sunlight more than the required levels or if you facing extreme hot weather.
Partial-shade is the method I follow. In extreme heat waves, my location can reach up to 100 degrees Fahrenheit, my last summer was around 110 degrees Fahrenheit. At that time, I moved my sun-loving plants into partial-shade areas. I saved my plants.
Clay pots are the best option for hot regions they absorb and hold water and they’re eco-friendly. Also, clay pots absorb low heat.
Plastic pots might be a considerable option if they’re UV-resistant. Because normal plastic with continuous Sunlight exposure damages the material.
Metal pots (a no) These pots are not a choice for summers because of their heat-absorbing nature.
Fertilisers in hot weather it is better to use non-synthetic organic fertilizers. Also, these slow-release fertilisers are effective for the long term.

COMMON MISTAKES TO AVOID WHEN GARDENING IN HOT CLIMATES

Some of us thought watering more was a solution to handle the heat like we had more water in summer. That’s a myth having empty water does not keep as hydrated, instead, we should intake healthy fruits and alter our diets. The same rule applies to our plants in hot weather. Here are some mistakes you should avoid in hot climates.

Overwatering

As I said earlier more watering is not a solution, instead you need to water how much the plant pot can hold. Deep watering is also helpful. The limited space only holds limited water so instead of water more water when you feel the top soil feel dry.

Most of the heat-tolerant plants love well-drained soil, so overwatering only makes the soil soggy and Heat-tolerant plants hate that.

Underwatering

Heat-tolerant plants need less frequent watering not no watering. Even they also slow their growth when they don’t receive enough water. Water deeply and check that water comes down under drainage holes that the sign of fully watered.

Choosing wrong plants

Choose plants that are heat-tolerant check the heat-tolerance level of the plant before buying or choose to place them in sunlight. Placing non-heat-tolerant plants in direct sunlight only burns down the plant.

Size of the Containers

Heat-tolerant plants are deep-rooted that hold and reach every part of the soil to access water. These bigger rooted plants struggle to grow in smaller pots. Choose a pot size that is 2 inches bigger than a plant’s root ball.

CONCLUSION

Choosing heat-tolerant plants with heat-resisting characteristics and growing them in your hot regions is a happy gardening experience. These plants gave the advantage of growing container plants outdoors, in sunny spots.
