Ideally, transplant your flowers, ornamental grasses, and foliage plants on a cloudy, overcast day that isn't too windy. Planting early in the morning before the sun heats up the soil will produce the best results. Vegetables fall into two categories: warm-season and cool-season.
Is It Better To Plant In The Morning or Evening? Planting flowers in the early morning is better for most species. But, some species may grow better if they are planted in the evening.
The best time to plant any plant is during the dormant season – in North America, this is usually late fall through early spring. While it's okay to plant during the rest of the year, it will require more maintenance from you in the form of watering, fertilizers, etc.
Planting or repotting tasks are best done in the evening or morning for saving plants from transplanting shock. Doing the same in the afternoon will expose them to intense heat, making them go into a state of shock.
Plant Seeds Before It Rains
Dry soil is easier to work with than wet soil and seeds are less likely to rot in soil that doesn't stay soggy for prolonged periods. Add in a nice rain shower, and you won't need to drag out the garden hose to water your newly planted seeds.
It usually takes a few days after a good rain for the soil to dry out enough that you can start planting. If you're unsure, push aside any mulch, dig 2 or 3 inches into the soil and take a handful. “If it clings together so you can form a fist of it, it's mud, and still too wet to work in,” Savio said.
Planting in wet soil conditions also creates lumpy soil, which is counterproductive to making seed beds with a fine tilth. Large clumps make it difficult to cover all the seeds to the correct depth and creates an uneven surface that doesn't retain a consistent amount of moisture across the bed.
Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.
How much water do plants need a day? Plants don't need daily watering. Instead, water deeply but less frequently. Deep waterings allow the water to seep beneath the roots, which encourages the roots to grow downward.
In the presence of light, plants direct their growth toward the light. The growth that occurs at night tends to be vertical, unaffected by this daytime tendency to reach toward the light. Some plants may even grow faster at night because during daylight they focus their energy resources on photosynthesis.
Planting at night is always a nice and secure idea. As was previously mentioned, temperatures are lower at night than they are during the day, which slows the rate of evaporation and reduces moisture, both of which are necessary for seeds to germinate successfully. Most plants do, in fact, grow more at night.
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 most vigorous growth of plants will be in the summer when the sun is up and out the longest. During winter, the sun is neither as high in the sky, nor in the sky for as long as it is in the summer. For your plants, that means less light. For some plants, this may trigger dormancy.
Planting and Transplanting
The best planting or transplanting time is on a cool or cloudy day, either early in the morning or the evening. This gives your transplants time to set and acclimate well. This also saves them from transplanting shock.
Remember morning sun is cooler and less intense. It does not lead to leaf scorch and stress. Some plants can tolerate a lot more sun if it was morning sun as opposed to the hot, scorching afternoon sun. Plant growers try to help us figure out the needs.
Generally, sunlight is best for plant growth but artificial lighting can improve the quality of light plants receive, improving plant growth. When artificial light is needed to supplement natural light, the spectrum (colors the lamp produces) is important.
Most plants shut down during extreme heat, so if it is over 100 degrees, it may be best to wait to water even if your plant is stressed. Throw a damp sheet over it, or mist it lightly to bring the temperature down.
Poor drainage or improper watering
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.
Provide Slow, Deep Watering
If you are unsure how long to water new plants, aim for 30-60 seconds for small plants – longer for larger plants while moving the hose to a few locations around the plant. Avoid watering when the soil feels moist. The earth must be allowed to dry out between watering.
Answer: Early morning (5:00 to 9:00 am) is the best time to water the garden when using a sprinkler, garden hose, or any other device that wets the plant foliage. When watering is completed, the plant foliage dries quickly. The rapid drying of plant foliage helps guard against the development of fungal diseases.
While watering your yard plants with bottled water may be impractical, using bottled spring water for your indoor plants will make a big difference for them. To give your plants the absolute best, rainwater and bottled spring water are your best options. Any water containing sugar or salt will hurt them!
After the soil is in place and well-watered, level the soil with a garden rake. A level soil will ensure that water flows down and through soil, and will help prevent surface erosion. STEP 2: Rest the Soil – Don't plant for at least 3 days!
The goal is to water the soil well to saturate it into the planting root zone. And give the soil plenty of time to drain slightly but not dry out completely before you plant.

Grab a handful of your garden soil. If you can form it into a ball, the soil is too wet for planting. (Chances are the seeds will rot.) If it crumbles through your fingers, it's ready for planting.
