How to keep Dimorphotheca Pluvialis.
Light
Weather prophet grows best with abundant sunlight. When given ample light, the plant can efficiently absorb nutrients, supporting its healthy development. It survives in extreme light conditions and has no limit to its tolerance. Neither excessive nor insufficient sunlight harms the plant; it is resilient in both cases.
Water
Originating from arid regions, the weather prophet plant efficiently conserves water and prefers drier conditions. It thrives in moderate humidity and can tolerate short periods of drought, requiring watering about once a week. Typically grown outdoors, the weather prophet plant displays responsive behaviors, such as closing its flowers before it rains.
Temperature
Weather prophet is indigenous to areas where temperatures typically lie between 68 and 100 °F (20 to 38 ℃). While it is a temperate woody plant, it shows a preference for warmer conditions. During changing seasons, careful adjustments in response to the prevailing temperatures are recommended.
Fertilizer
When most of Weather prophet's blooms have opened to full size, resume fertilizing. At the time the blooms are at their peak, feed it once every three to four weeks, as the weather allows. Then, when Weather prophet begins to produce fewer new blooms, cease fertilizing; there's no reason to fertilize if the plant can no longer set additional flowers.
Pruning
The weather prophet plant is known for its long blooming seasons. To encourage new growth, it requires pruning in early spring to remove dead stems. Additional pruning can also help shape the plant. Regular deadheading prolongs the flowering period. Make clean cuts just above the leaf nodes to enhance the plant's health and maintain its vibrant appearance.

Reader questions.
How should I water my Weather prophet?
To water the Weather prophet plant, there are several options you can choose from. You can use a garden hose with a spray nozzle, a watering can, or any other watering tool you have on hand. The good news is that the Weather prophet plant is not picky about the type of water it receives. It can thrive with rainwater, tap water, or even filtered water. However, it's best to avoid watering it from above as this can cause damage to its leaves and flowers, and it may also make the plant more susceptible to disease. In these cases, using a drip irrigation system works best. This way, water is applied evenly and directly to the soil, which is ideal for the Weather prophet plant. If you have a container-grown Weather prophet, you can apply water directly to the soil by using a cup, watering can, or your tap. The same principles apply, just with different tools.
Why should I add fertilizer to my Weather prophet?
Gardeners know that plants need nutrients to survive. This is especially important for Weather prophet, as it will die soon after its first pollination if it doesn't receive enough food. To ensure Weather prophet thrives and produces beautiful flowers throughout the blooming season, it's crucial to provide the right type and amount of nutrients. Fertilizer is particularly beneficial for Weather prophet's thin and easily damaged root system. By fertilizing at planting, Weather prophet can develop a strong root structure that provides stability and enhances its ability to produce sensational flowers. Timely fertilization can also significantly extend the flowering period of Weather prophet.
What are the sunlight requirements for a Weather Prophet plant?
The Weather Prophet plant requires full sun, meaning it should receive above 6 hours of sunlight daily. It's important to observe how sunlight moves through your garden to find spots that provide a balance of light and shade, ensuring your plant's happiness. Weather Prophet thrives best under plentiful sunlight, effectively absorbing nutrients for healthy growth. It can survive harsh light conditions and is resilient to both over-exposure and under-exposure to sunlight.
What is the ideal temperature range for a Weather prophet?
The Weather prophet, also known as Dimorphotheca pluvialis, thrives in environments where temperatures typically range between 68 to 100°F (20 to 38°C). Originating from temperate woody areas, it shows a pronounced preference for warmer climates. To ensure its well-being, it's advisable to adjust its care with the changing seasons, especially prioritizing temperature management. During winter, maintaining the temperature above 20°C is crucial for the plant's growth, while ensuring it is not exposed to temperatures nearing 0°C, which can be harmful.
What should I do if I give too much or too little water to my Weather prophet?
To avoid underwatering your Weather prophet plant, simply water it more often when you notice it needs moisture. Overwatering is a more serious issue that can lead to diseases and the plant's decline or death. To prevent this, choose a location with plenty of sunlight and good drainage to avoid waterlogged soil. If your potted Weather prophet is overwatered, consider changing it to a new pot with proper drainage and loose soil when repotting.
When should I fertilize my Weather prophet?
Weather prophet experiences significant growth early in the growing season after the threat of the last frost has passed. This is the optimal time to fertilize the plant, specifically during planting, whether it's placed in the ground or in planters. This initial fertilization is the only dose required until later in the year when the plant is in full bloom. Once the growing season is underway and the majority of blooms have reached their full size, it is time to resume fertilizing. This should be done approximately every three to four weeks, taking into consideration the prevailing weather conditions. As Weather prophet starts to produce fewer new blooms, it is advisable to discontinue fertilization. There is no need to fertilize when the plant is no longer capable of producing additional blooms.
Can Weather Prophet plants grow under artificial lighting?
Yes, Weather Prophet plants can grow under artificial lighting, especially when natural sunlight is insufficient, such as in winter or in less sunny spaces. Artificial lights, like LED lights that can be customized to specific wavelengths, are beneficial for promoting faster, healthier growth. For optimal growth using artificial light, full sun plants need 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft. The artificial light source should be placed 12-36 inches above the plant and turned on for 8-12 hours per day to mimic natural daylight hours.
How should I care for my Weather prophet during colder months?
In the colder months, the Weather prophet requires special attention to protect it from low temperatures. It is recommended to bring the plant indoors and place it near a bright window to ensure it receives sufficient light, though it should be kept at a certain distance from heaters to avoid damage. The plant thrives best when the temperature remains above 20°C and should not be allowed to drop to 0°C or lower. Exposure to temperatures below -5°C can cause the leaves to lighten in color, followed by wilting and drooping after frost damage. If frost damage occurs, affected parts should be trimmed off, and the plant should be moved to a warmer indoor setting promptly, ideally near a south-facing window while avoiding excessive dryness caused by heaters or air conditioning vents.
How frequently should I water my Weather prophet?
To keep your Weather prophet plant healthy, it is important to water it regularly. In the spring, watering once per week is sufficient. However, as the weather gets warmer, you may need to increase the frequency to two to three times per week. It's important not to overwater the plant, as this can harm it. The soil should be kept moist, but not saturated. If your Weather prophet is in a pot, it will need to be watered more frequently compared to if it was planted in the ground. This is because the soil in pots can heat up and dry out faster. Typically, watering a potted Weather prophet a few times per week is recommended, compared to just once per week for a plant in the ground.
When is it best not to fertilize my Weather prophet?
Regular fertilizing is important for Weather prophet, but it is crucial to apply it at the right time. Some situations require pausing fertilizer application, which are typically related to climate but also involve various controllable factors. In essence, when something is amiss with the plant, soil, or climate, it is best to wait until the issues are resolved and the plant has recovered. For example, it is not advisable to fertilize if there are severe or sudden weather changes. If there is a sudden cold spell in the middle of summer, it is better to wait until it warms up again before applying fertilizer. The same applies if the soil is too dry or compacted to absorb anything effectively. In such cases, the fertilizer will not be properly diffused by the soil and will go straight to the roots, which is not ideal for Weather prophet. When temperatures rise to the 90-degree Fahrenheit range during the hottest parts of the day, refrain from fertilizing. As fertilizer can break down at varying speeds depending on temperature, it is particularly important not to allow the heat to break it down too quickly. Additionally, any pests or diseases should be dealt with and resolved before re-fertilizing.
What are the common symptoms of inadequate lighting for Weather Prophet plants?
Weather Prophet plants may show several symptoms when they don't receive adequate light, including smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, lighter-colored new leaves, chlorosis, and damage symptoms like sunscald, leaf curling, wilting, and leaf scorching. These symptoms indicate a plant's struggle with either too little or too much sunlight, affecting its growth, leaf color, and overall health.
How does high temperature affect Weather prophet and what are the solutions?
Weather prophet prefers not to be exposed to temperatures above 38°C. High temperatures, especially those exceeding 43°C, can lead to lighter leaf coloration and increase the plant's susceptibility to sunburn. To mitigate these effects, it's advisable to trim away sunburned or dried-up parts of the plant and move it to a shaded area, particularly to protect it from the midday and afternoon sun. Ensuring the plant is watered in the morning and evening will help keep the soil moist, further protecting it from the adverse effects of high temperatures.
