Yes, you can plant nasturtium indoors as long as you provide them with enough sunlight, well-draining soil, and regular watering. Nasturtiums are relatively easy to grow indoors and can thrive in containers or hanging baskets. Just make sure to place them in a sunny spot and provide support for them to climb if needed. **

There are several possible reasons why your nasturtium plant may be sick. It could be due to overwatering or underwatering, which can lead to root rot or dehydration. It could also be suffering from a lack of sunlight or poor soil quality. Additionally, pests or diseases such as aphids, caterpillars, or powdery mildew could be affecting the health of the plant. It's important to assess the growing conditions and address any potential issues in order to help the nasturtium plant recover. **

Nasturtiums may only produce leaves if they are not receiving enough sunlight. Nasturtiums thrive in full sun and may not flower if they are in a shaded area. Additionally, over-fertilization with high-nitrogen fertilizers can also cause excessive leaf growth at the expense of flowers. Lastly, if the plant is too young, it may not have reached the stage of flowering yet. It's important to ensure that the plant is receiving adequate sunlight, the right type of fertilizer, and is mature enough to produce flowers. **

The pest that causes leaf mines on nasturtium plants is the larvae of the black vine weevil (Otiorhynchus sulcatus). These small, grayish-brown beetles lay their eggs in the soil near the base of the plant, and the larvae then feed on the roots and tunnel their way up into the stems and leaves, creating characteristic leaf mines. This can cause damage to the plant and reduce its overall health and vigor. Regular monitoring and control measures such as removing affected leaves and using insecticidal sprays can help manage this pest. **

To combat caterpillar infestation on your nasturtium plant, you can try picking them off by hand and disposing of them. You can also introduce natural predators like ladybugs or lacewings to help control the caterpillar population. Additionally, you can use organic insecticidal soap or neem oil as a natural and safe way to deter caterpillars from feeding on your plant. Regularly inspecting your plant for signs of caterpillars and taking prompt action can help prevent further damage. **

A gas heater uses a spark to ignite the gas and create a flame. Once the gas is ignited, it continues to burn and produce heat without the need for a continuous spark. Therefore, after the initial spark, there is no need for it to remain lit as long as the gas is burning. This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **

To heat a plate over a candle flame, you can hold the plate above the flame at a safe distance to avoid direct contact with the flame. Move the plate back and forth over the flame to evenly distribute the heat. Be cautious not to hold the plate too close to the flame to prevent it from getting too hot or potentially breaking. **

No, ember is not hotter than fire. Ember is the glowing remains of a fire that has started to die down, whereas fire is the active, burning flames produced by a combustion reaction. Fire typically burns at a higher temperature than ember, as it is actively consuming fuel and releasing heat and light. **
