INTRODUCTION
Container Gardening is a method that offers mobility and is easy to grow in small spaces. However, some of us face issues of lack of sunlight or are confused about how much sunlight a plant needs. Plants’ sunlight needs differ. Understanding the sunlight needs and how this sunlight works on plants helps you find the right spot for plants.
To put it simply Sunlight helps the process of sunlight and provides energy to produce flowers, fruits, and vegetables. The role of Sunlight in Photosynthesis is that plants convert the light into energy, this energy fuels growth allowing plants to produce leaves, stems, and flowers.
Sunlight strengthens the stems and leaves that way plants growing in direct sun or brighter light are sturdier and stronger (e.g. tress). Strong plants that grow in direct sunlight produce more leaves, stems, and flowers. Also, sunlight makes the plant more disease-resistant and pest-resistant.
The plant has different sunlight needs, some plants like bright and direct sun some plants love semi-shade areas to thrive. Understanding your plant’s sunlight needs is also important. But whatever the plant’s sunlight needs, ignoring them leads to less photosynthesis process which means slow growth, weak plant structure, stunted growth, colour and foliage vibrancy of plant become dull, temperature regulation becomes unstable, and low disease resistance.
To avoid these conflicts, just know the importance of sunlight and utilize that for your plants. In this Blog Post, you will learn about how much sunlight your plants need, how to manage sunlight in container gardening, signs of sunlight lacking, and more. Buckle up and learn more about sunlight’s role in gardening.
1. THE ROLE OF SUNLIGHT IN PLANT GROWTH
- Understanding Photosynthesis: How Plants Use Sunlight to Grow
In the Photosynthesis process plants convert sunlight into energy, Photosynthesis converts light energy into glucose the energy allows the plants to grow stems, leaves, and flowers. Photosynthesis primarily happens in leaves, specifically within tiny structures called Chlorophyll, this chlorophyll captures sunlight and uses it to power the chemical reaction that transforms water and carbon dioxide into glucose (a form of sugar) and oxygen.
This Glucose acts as fuel for plants’ cellular activities, cell division, and development. Glucose helps to form new cells, allowing plants to grow taller, spread leaves, produce flowers, and expand the root system. For us it just watering and sunlight, for plants it’s a lifeline inside it. Especially blooming period needs the right sunlight and watering to get better results.
In container gardening the space is limited, and soil and nutrients are also limited so the energy from photosynthesis is even more important in plant growth. Plants must rely heavily on photosynthesis for growth, nutrient absorption, and stress resistance. Proper sunlight exposure is important for container gardening plants.
- How lack of Sunlight Impacts Container Plants
Slow Growth: limited sunlight affects the photosynthesis process which creates a lack of glucose that affects thriving.
Weak, Leggy stems: lack of sunlight makes the plants stretch through sunlight with weak stems.
Pale leaves: Chlorophyll production drops causing leaves to lose their colour.
Reduced Flowering: Low glucose reduces the blooming.
Low-disease resistance: Lack of sunlight weakens the plants which can be easily affected by pests and disease.
2. HOW MUCH SUNLIGHT DO CONTAINER PLANTS NEED?
- Full-sun, Partial sun, and Shade-loving plants: choosing the right plants for your space.
Full-sun plants like vegetables, fruits, leafy veggies, cacti and succulents love full sun and thrive in full sun. Also, heat-tolerant plants are preferable for full sun. These plants are ideal choices for outdoor spaces and direct sunlight.
Partial sun Plants are houseplants, flowering plants, vining and climbing plants, and herbs these plants need sunlight but not direct sunlight. Ideal for balcony, patio, and semi-shade areas.
Shade-loving plants are mostly houseplants, and few flowers and herbs. These plants tolerate low light but ensuring watering and potting mix is ideal.
- Understanding sunlight hours and Positioning Container Plants
Full Sun 6-8 hours or more than that of direct sunlight daily. Partial sun 3-6 hours of direct sunlight. Full shade less than 3 hours of sunlight in a day.
In the Northern Hemisphere (North America, Europe, Africa, and Asia) south facing locations gets the most consistent sunlight throughout the day. A south-facing balcony, patio, or garden side, inside the setback area, consistently provides sunlight with bright direct sunlight.
This sunlight slightly changes every 6 months in monsoon and winter the sunlight comes mostly from the north, in summer and spring the sunlight comes mostly from the south.
- How to measure sunlight hours for your spot
# Pick a clear day to measure sunlight accurately, not a cloudy or rainy day.
# Observe the area’s sunlight from 6 am to 6 pm, and take photos every 1 hour to calculate sunlight hours.
# Note the start time the hour the first sunlight hits and note the end time the sunlight ended time that is the sunlight hours of the spot.
# You can also use sunlight metres to the particular spot to measure sunlight.
# The angle and duration change with seasons. In summers the sunlight is stronger and longer, In winter the angle is lower and less duration.
3. BEST PRACTICES FOR MANAGING SUNLIGHT IN CONTAINER GARDENING
In container gardening, you might have a lack of sunlight spots. In that case, you can adopt these tricks to get sunlight to your plants in alternative ways.
- Reflective surfaces to maximise the sunlight
Set up the plants near white painted walls, or white panels or reflective panels to get the reflection of sunlight. These surfaces help to redirect the sunlight to shaded areas, that way using white paints in the house brings more light to a home.
Position these panels to face the main light source like a nearby window or open area to bounce more light directly into your plants. Using white-coloured pots or light-coloured pots reflects the light around the plants’ base and foliage.
Positioning plants around light-coloured or white-coloured walls helps to get the reflection of sunlight. Using mirrors is also helpful to get sunlight reflections, (that’s why greenhouse plants grow better). Avoid too much focusing mirrors on plants can cause scorching.
- Artificial lighting for Container Plants
Grow lights are helpful for zero sunlight spots, and indoor plants. Some of the plant enthusiasts build mini greenhouse shelves indoors and use grow-light to grow plants. Nothing is a barrier for a gardening enthusiast.
These Grow lights are ideal for shady corners and spots in the home that sunlight can’t reach. You can use these lights to fulfil the plants light requirements. These grow lights don’t look different or weird than normal lights.
- Protecting plants from Harsh Sunlight
In the above paragraphs, you see how to get sunlight, but excess direct sunlight burns the plants. Like direct sun in summers or hot and dry climate areas. This problem mostly happens for terrace gardeners and open gardeners.
In heat weather, you can use a shade net to protect your plants from sunburn aka scorching. For terrace gardens, it’s better to put a shade net or move plants into the shade till summer ends is a good option. For the Balcony or Patio, you can use roll-up blinds to prevent direct heat waves in the afternoons.
4. SIGNS YOUR CONTAINER PLANTS NEED MORE OR LESS SUNLIGHT
- Symptoms of Sunburn in Container Plants and How to Prevent It
These are the signs of sunburn, Brown and white spots on leaves, crispy leaves and the leaf ends are crispy, leaf curling and wilted leaves are common signs. Leaves absorb the sunlight and turn it into energy so the leaves always show the signs.
If you see these signs in plant leaves try to move the plant to shade areas, or use a shade cloth to prevent the sun from burning. In summer try to move pots from direct sun, 11 am to 4 pm sunlight are harsh in summer, especially in India.
Try to use a water retention potting mix, follow proper watering, using self Watering pots are other helpful practices to prevent your plants from direct sun.
- Common Indicators of Sunlight Deficiency in Container Plants
The first sign of a lack of sunlight is yellow leaves and mushy leaves. Leaf drop is another symptom of sunlight deficiency. Water takes longer to dry out in potting mix, and stunted growth, pest attacks and fungal infection are also signs of sunlight deficiency.
To solve this issue., find your plants’ ideal sunlight need and place the plant according to the sunlight need. Don’t overwater these plants, only water them when the soil is dry.
5. TOP CONTAINER PLANTS THAT THRIVE IN DIFFERENT SUNLIGHT CONDITIONS
- Best Container Plants for Full Sun and Partial sun
As I already mentioned in most of the previous posts, choosing plants based on sunlight is important.
For Full sun, Choose heat tolerant and sun loving plants like vegetables, drought-tolerant tolerant herbs like lavender and rosemary, flowering plants like marigold and roses.
For Partial shade, choose shade tolerant plants like ferns, snake plant, calatheas, begonia, spider plants and peace lilies.
CONCLUSION
Knowing the role of Sunlight, how it impacts plant growth and how it supports the plant’s yield is important to utilise the sunlight for your container plants.
