Do plants need sunlight or just heat?

Direct sunlight and high temperatures should be avoided as much as possible. This may sound contradictory, because light and heat are essential for the growth of plants, so-called photosynthesis. For an optimal growth there should be a good balance in climate between temperature, light and humidity.

Is it better to water plants in the morning or evening on a hot day?

The best time to water outdoor plants is in the morning when temperatures are usually cooler. This gives the plants time to absorb the water so they can get through a long, hot day. The second-best time is late in the afternoon or early in the evening. Try not to water at night.

The best time to water plants is in the morning or evening.

More importantly, watering at these times actually helps the plant retain water. If you water in the afternoon, especially during summer, the heat and sun are at their peak and the plant's water will evaporate instead of absorbing into the soil and roots.

How do you tell if a plant is overwatered?

When a plant is first becoming overwatered, leaves turn yellow. If soil doesn't have a chance to dry out before you water again, leaves start to wilt. When overwatering is the problem, wilted leaves are soft and limp. (If too little water is the issue, wilted leaves are dry and crispy.)

Growth and shape

A happy plant changes shape as it keeps growing with compact stems and beautiful sprouts. If your plant is too static, it may benefit from more sunlight exposure or a nutrient boost.
