Care Guide

💧 Water

Balfour's touch-me-not, a plant native to the Himalayas, thrives in moist and humid environments and is surprisingly drought-tolerant. It requires weekly watering to maintain even moisture levels without becoming waterlogged. As an annual herb, it grows well outdoors, where natural rainfall during its growing season often provides sufficient water, reducing the need for extra irrigation.

FAQ
How should I water my Balfour's touch-me-not plant?

To water Balfour's touch-me-not plants, you have a few options. You can use a garden hose with a spray nozzle, a watering can, or any other common watering tool. These plants are not too picky about their water source and can thrive with rainwater, tap water, or filtered water. It's usually best to avoid watering these plants from overhead because it can harm the leaves and flowers and potentially cause disease. Instead, a drip irrigation system is often the most effective way to water them. These systems evenly and directly apply water to the soil, which works well for Balfour's touch-me-not. If you have a Balfour's touch-me-not in a container, you can still use a similar watering approach but with different tools. Use a cup, watering can, or tap to apply water directly to the soil of the container-grown plant.

What should I do if I give my Balfour's touch-me-not plant too much or too little water?

To address the issue of underwatering Balfour's touch-me-not, the solution is simple - increase the frequency of watering when you notice the lack of moisture. On the other hand, overwatering can be a more serious problem if not detected early. Overwatered plants are susceptible to diseases that can lead to their decline and death. To prevent this, choose an appropriate location for growing that receives ample sunlight to dry out the soil and ensure good drainage to avoid waterlogging. If you have overwatered a potted Balfour's touch-me-not, consider changing to a new pot with better soil drainage and more drainage holes. When repotting, add loose soil and use a pot that drains efficiently.

How many times do I need to water my Balfour's touch-me-not plant?

To properly care for your Balfour's touch-me-not, you'll need to water it regularly. In the spring, watering once a week should be sufficient. However, as the weather gets hotter, you may need to increase watering to two or three times a week. Be careful not to exceed this frequency, as it can harm the plant. It's important to keep the soil moist but not overly wet, regardless of how often you water. If your Balfour's touch-me-not is in a pot, you'll need to water it more frequently than an in-ground plant. Potted soil tends to heat up and dry out faster, so watering a few times a week is generally necessary compared to just once a week for plants in the ground.

How much water does my Balfour's touch-me-not plant need?

Determining how much water to give your Balfour's touch-me-not can be approached in a few ways. Some gardeners judge the water volume by checking the soil's moisture level. According to this method, you should water until the top six inches of soil feel moist. Another approach is to follow a specific measurement. For Balfour's touch-me-not, around two gallons of water per week is typically recommended, although this may vary depending on the temperature and how quickly the soil dries out. However, sticking strictly to this guideline may result in overwatering if your plant needs less water. When growing this plant in a container, a different technique is necessary to determine the appropriate water amount. In this case, water should be supplied until all layers of dry soil are moistened. To check if this has been accomplished, you can insert your finger into the soil or observe a slight trickle of excess water draining from the pot's holes.

How can I know if I am not giving enough water to my Balfour's touch-me-not plant?

Avoiding overwatering your Balfour's touch-me-not can be tricky. While they have deep roots that need regular moisture, these plants are also prone to root rot and browning when overwatered. Underwatering is less of a concern as they can survive without extra watering for a while, but if left without water for too long, the plant will wilt and develop dry leaves.

☀️ Light Partial sun

Balfour's touch-me-not prefers a spot with moderate sunlight, since it comes from areas where sun and shade are often mixed. Although overly strong or too weak light can affect its development, this plant does not require particular light conditions at different growth stages.

🌱 Fertilizer

When most of Balfour's touch-me-not blooms have opened to full size, resume fertilizing. During the period when blooms are at their peak, fertilize every three to four weeks, weather permitting. Then, once the plant begins producing fewer new blooms, stop fertilizing; there is no need to feed it when it can no longer produce more blooms.

FAQ
Why should I use fertilizer for my Balfour's touch-me-not?

Plants require nutrients to survive, and most gardeners understand this well. However, without proper nourishment, Balfour's touch-me-not will quickly die after its first pollination. To ensure its continued growth and the production of vibrant flowers, it is crucial to provide this plant with the right nutrients in appropriate amounts. Fertilizer plays a significant role in strengthening Balfour's touch-me-not's root system, which is delicate and vulnerable to damage. By fertilizing during planting, the plant's root structure becomes more robust, offering stability and setting the stage for an impressive flowering display. When timing is appropriate, fertilization can effectively lengthen the duration of Balfour's touch-me-not's blooming period.

When should I fertilize my Balfour's touch-me-not plant?

Balfour's touch-me-not grows rapidly once the last frost danger has passed. It's best to fertilize during planting, when the plant is first placed in the ground or in planters. This initial dose of fertilizer is sufficient until later in the year when the blooms are fully open. Once the plant is in full swing and most of the blooms are open, it's time to start fertilizing again. Fertilize every three to four weeks, as weather permits, when the blooms are at their peak. As the plant starts producing fewer new blooms, stop fertilizing since it won't produce any more blooms.

When is it best not to put fertilizer on my Balfour's touch-me-not?

Regular fertilizing is important for Balfour's touch-me-not, but it should not always be applied. There are certain situations when it is better to hold back on fertilizer. These situations are typically related to the climate or other controllable factors. If something is wrong with the plant, soil, or climate, it is best to wait until the issue is resolved and the plant has recovered before fertilizing again. For instance, if there are sudden or extreme changes in the weather, such as a cold snap in the middle of summer, it is advisable to wait until the temperature becomes warmer before applying fertilizer. Similarly, if the soil is too dry or compacted, it won't be able to absorb the fertilizer properly, and it may end up going straight to the roots, which can harm the plant. In addition, it is not recommended to apply fertilizer during the hottest parts of the day when temperatures reach around 90 degrees Fahrenheit. This is because high temperatures can cause the fertilizer to break down too quickly, which may not be beneficial for the plant. It is also important to address any pest or disease issues before reapplying fertilizer.
