Extreme heat can inhibit photosynthesis, the process by which plants convert sunlight into energy. When temperatures are too high, the enzymes involved in photosynthesis become less efficient, reducing the plant's ability to produce energy. With reduced energy production, plant growth is stunted.
So, how hot IS too hot for plants? The general answer is around 90 degrees F, with some exceptions to the rule. This means that when temps rise above 90 and remain there for a lengthy spell: Leaves wilt.
The 70/30 Rule of Gardening suggests that roughly 70 percent of your garden should be planted with reliable, proven plants that perform well in your climate and soil conditions. The remaining 30 percent is reserved for experimentation—new varieties, unfamiliar techniques, or crops you've never grown before.
Plus, October also marks the beginning of bare-root planting season, so you can plant bare-root apples, pears and other fruit trees, along with fruiting shrubs such as blackcurrants and gooseberries. There's also still time to plant spring bulbs.
Plants are surprising organisms—without brains and central nervous systems, they are still able to sense the environment that surrounds them. Plants can perceive light, scent, touch, wind, even gravity, and are able to respond to sounds, too.
That's why Feng Shui and interior design experts say it's a mistake to choose one of these five houseplants you should never place in your bedroom:
While they don't have nervous systems, like humans do, plants react to light, sound, touch, and even subtle vibrations. Studies show they alter their growth patterns, leaf movements, and responses when touched, exposed to sound, or surrounded by human presence.
Hotter summers, extended droughts, and dry winds are becoming more common, and hydrangeas are paying the price. Gardeners from coast to coast report the same issues: leaves crisping and curling in early summer, stems wilting despite regular watering, and blossoms fading far too quickly.

Arugula is a fast-growing leafy green that can be ready to harvest in just 20-25 days. It thrives in cooler temperatures and prefers partial shade. Sow the arugula seeds directly in pots or garden beds, and keep the soil evenly moist. Harvest the leaves when they are young and tender for the best flavour.
The 3-hour rule is simple: avoid gardening between 11 a.m. and 2 p.m. during the summer months. That's when: Plants are stressed. They conserve their energy and close their leaf pores to survive. UV rays are strongest, which puts gardeners at the highest risk for sunburn and skin damage.
Plants prefer to rest between waterings. Keeping the soil too moist all the time can rot the roots. OVERWATERING is the #1 killer of houseplants.
During extremely hot weather (daytime temperatures above 90°F and nighttime temperatures above 70°F), try to water daily or every other day. In a 10x10-foot garden, this would mean giving your plants 8 to 9 gallons of water each day.
