Care guide

Keeping summer plant in india healthy is easier than you think. Follow these simple care tips to enjoy colourful blooms throughout the hottest months.

1. Water at the Right Time

Water plants early in the morning, before 9 am if possible. The roots get plenty of water before the heat of the sun. Do not sprinkle too early in the morning, as much of the moisture will be lost by morning. If it is very hot, potted plants might require daily watering, but make sure to water based on soil moisture rather than by a schedule.

2. Provide a sufficient amount of sunshine.

During the summer, most flowering plants for indian summer will require 6-8 hrs of direct sunlight daily to grow and produce continuous flowers. However, plants in pots that can be damaged by temperatures above 40°C can appreciate a bit of shade in the afternoon to avoid leaf scorch and flower drop. Position containers in a spot with lots of morning sun and some shade in the middle of the day.

3. Use Well-Drained Soil

Over the summer, good drainage is critical. Mix garden soil, compost, and sand/perlite to ensure drainage. The waterlogged soil condition can cause root rot, and loose, well-aerated soil will help maintain a healthy root structure and promote good blooming.

5. Apply Mulch Around the Roots

Mulch soils with dry leaves, coco chips, straw, or bark. Mulch also holds moisture in the soil, retains soil temperature, decreases water evaporation, and slows weed growth. It also means that on hot days, it will require less watering.

5. Feed Plants Carefully

Flowering plants require feeding, but make sure not to feed during hot weather. Use a balanced liquid fertilizer or organic compost every 3-4 weeks in moderate temperatures. Excessive fertilizer under intense temperatures can stress the plant roots, as well as cause plant deficiency.

6. Remove Dead Flowers Regularly

Regularly remove deadheading, old leaves, and dry stems. This is known as dedheading and is a way for the plant to produce more buds rather than seeds. It also maintains a neat appearance of plants, helps with ventilation, and limits the chances of pest and fungal infection.

Balcony recommendations

Even a small balcony can become a colourful garden if you choose the right setup. These simple tips will help your low-maintenance summer plants stay healthy and bloom for longer.

1. Choose Plants Based on Sunlight

Decide the amount of sunlight your balcony receives prior to purchasing plants. When growing in 6-8 hours of direct sunlight, choose plants like Bougainvillea, Portulaca, Sunflower, and Adenium. If your balcony is exposed to just a few hours of sun, take to the garden plants that will thrive in part sun, such as Periwinkle, Hibiscus, and Marigold.

2. Use the Right Pots

If you use pots with drains, the excess water can drain away. Light plastic pots are perfect for hanging planters and railings, while terracotta pots will hold heat in summer and promote better root ventilation. Use the larger containers as they will retain moisture longer and allow roots some room to grow.

3. Get the best use of the space vertically.

When space is limited, consider moving up, rather than moving out. Grow more flowers and don't spread over floor space by using vertical plant stands, railing planters, hanging baskets, or wall planters. Climbers such as bougainvillea can also be trained up along balcony railings or up on trellises for a beautiful flowering display.

5. Keep out of Sunlight during Heatwaves

Balconies often become hotter than gardens because concrete reflects heat. On very hot afternoons, consider patrolling plants slightly away from the railing or place a 50% shade net, bamboo blind, or outdoor curtain over the flowers to prevent them from being sunburnt. This is an easy step that you can take to avoid leaf burn and drop of flowers.

5. Group Plants Together

Keep pots together, don't scatter them throughout the balcony. Plants in groups maintain a microclimate that lessens evaporative loss during periods of warm weather. This also makes watering more convenient, and provides your balcony with a richer and more decorative appearance.

6. Add Colour with Different Plant Heights

When using trailing or compact plants, place them toward the edge or in hanging baskets, medium-sized plants at the center, and tall plants, such as periwinkles or marigolds, towards the back of the container. Combining a variety of heights and colours will give even a small balcony a luxuriant, lively, and expertly arranged appearance.
