NOTE: The terms Lupine and Lupinus x hybrida are identical in this text; in reality, Lupinus x hybrida is Lupine’s biological word.
lupines come into bloom in the springtime and create colorful spikes in gardens. There is nothing subtle about the shape and color of hybrid lupines. A tall, showy spire of flowers that can come in a variety of colors is the telltale look. The foliage is similar to palm leaves with seven to 10 leaflet segments.
This fast-growing flower is available as both an annual and a perennial. They’re best planted in the spring when starting with a new plant and seeds can be planted late in the fall. The plant can be toxic to both humans and animals.
Why does my Lupinus x hybrida roots have rot?
Root rot on your Lupine (Lupinus x hybrida) can be dangerous if left untreated. In order to keep your plant alive, we strongly suggest that you follow our advice if the signs start to show: blackened and mushy roots.
Why does my Lupine have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Lupinus x hybrida being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.
Why does my Lupine have leaf spots?
This type of disease is one of the most frustrating for Lupine owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my Lupine leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some signs of yellowing caused by the many deficiencies on the Lupinus x hybrida in question:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
- Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my Lupine sunburned?
You can easily tell if your Lupine (your Lupinus x hybrida) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Lupine can also change color in case it gets too much water or not enough light, as we saw above.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my Lupine leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Lupinus x hybrida in direct sunlight?
No! If your Lupinus x hybrida (or Lupine) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Lupine is in such a state!
As explained in the paragraph above, the solution is simple, just place your Lupine in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Lupinus x hybrida leaves drooping or wilting ?
This typically occurs when your Lupinus x hybrida gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
An easy way to know if your Lupinus x hybrida is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!
If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Lupine right away after a dry time because you think it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Lupinus x hybrida
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Lupinus x hybrida.
The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.
Always keep temperatures stable
It’s also a good idea to keep your Lupinus x hybrida at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Lupinus x hybrida away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Lupine Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
This would be a true journey into hell for your Lupine and would also satisfy the pests.
To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!
Keep drainage in mind
If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
