Bower spinach requires full sun, which means it needs more than 6 hours of sunlight daily, but it can also tolerate partial sun, receiving about 3-6 hours of sunlight. It's important to watch how sunlight moves through your garden to find spots that provide a balance of light and shade, ensuring your plants thrive.

Bower spinach thrives in areas that receive all-day illumination but can also grow in moderately lit areas, sustaining its growth even with a moderate amount of light. Although harsh direct exposure is not harmful, insufficient light might limit its robust growth. Originating from fully illuminated climates, this leafy green has adapted to such conditions. In contexts where natural sunlight is insufficient, artificial lighting, such as LED lights, can be used to provide the necessary wavelengths of light, promoting faster, healthier growth. Depending on the plant's needs, 30-50W/sq ft for full sun plants, 20-30W/sq ft for partial sun plants, and 10-20W/sq ft for full shade plants are recommended. The appropriate distance for the light source is 12-36 inches above the plant, and most plants need 8-12 hours of light per day.

Bower spinach can exhibit several symptoms when it's not receiving enough light, including small leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, lighter-colored new leaves, chlorosis, sunscald, leaf curling, wilting, and leaf scorching. These symptoms vary from minor, such as smaller new leaves and extended spaces between leaves, to more severe, such as leaf scorching and wilting due to excessive sunlight.

To ensure optimal growth for indoor Bower spinach, gradually move plants to sunnier locations until they receive at least 6 hours of direct sunlight daily, using south-facing windows for natural light and keeping curtains open. For plants that are large or not easily movable, consider artificial lighting, keeping lamps on for at least 8 hours daily. For outdoor plants, gradually acclimate them to sunnier spots to prevent sunburn. If sunlight is blocked by trees or other obstructions, consider pruning or transplanting smaller plants during their dormant period for better light exposure. Note that parts of the plant already affected by insufficient sunlight may not recover, but new growth should be healthy with improved lighting.

Bower spinach, with its botanic name Tetragonia implexicoma, thrives best in moderate to slightly warm temperatures, specifically within a range of 15-38°C (59-100°F). This preference indicates that while it can adapt to different seasons, it might require adjustments to its growing environment to ensure optimal growth. Furthermore, Bower spinach possesses some level of cold tolerance, making it unnecessary to take additional protective measures when temperatures are above -5°C. However, if temperatures are expected to drop below this threshold, temporary protections like wrapping the plant in plastic film, fabric, or similar materials are advisable. It's crucial to remove these protections once the temperature rises to prevent any potential damage to the plant.

Bower spinach demonstrates a moderate tolerance to low temperatures, optimal growth occurring when conditions remain above 15°C. During winter, ensuring the plant's environment does not drop below -5°C is key to its survival. Should the temperature fall beneath -10°C, Bower spinach's leaves may begin to droop, indicating the onset of stress. While some instances may see a recovery, more severe cases will result in leaves wilting and eventually detaching from the plant. To avoid such damage, it's recommended to trim away any frost-affected areas and prepare the plant for colder conditions by wrapping it with non-woven fabric or cloth and setting up a wind barrier for extra protection.

In the summer months, when temperatures can climb above optimal conditions, Bower spinach needs protection to prevent overheating, especially when the mercury surpasses 38°C. If the temperature reaches over 43°C, the plant may exhibit stress signs such as a paler leaf color, dry and withered leaf tips, leaf curling, and an increased risk of sunburn. To mitigate these effects, it's advisable to remove the damaged portions of the plant and relocate it to a shaded area or utilize a shade cloth to shield it from the intense midday and afternoon sun. Adequate watering in the morning and evening hours will also help in maintaining soil moisture, which is crucial for the plant's health under high temperature conditions.
