Angel trumpet gets yellow leaves - causes & treatment tips


The Content Of The Article:

If the leaves of the angel's trumpet turn yellow, this can have several causes. In principle, however, they can all be controlled.

Yellow leaves are often caused by lack of water

Pink, yellow or bright orange - this is how the big chalices of the angel's trumpet bloom in summer. Provided the nightshade plant feels well. However, when angel trumpets get yellow leaves, nothing turns out so quickly. Reason for this may e.g. Lack of water. But also nutrient deficiency or spider mites can be to blame because the leaves of the angel trumpet turn yellow.

Causes & Treatment Tips

Cause # 1 - Water shortage:

Angel trumpets have a high water requirement, which increases in heat and direct sunlight. Sagging, hanging or yellowing leaves may be an indication that you are not watering the plant properly.

Treatment:

Add water to the bucket in the morning until it collects in the lower pot. If the plant has absorbed the water until the evening, add a little less.

If water shortage is the cause of the flabby, yellowish leaves, the problem is solved by casting within a few hours. You can literally watch as the liquid in the plant rises and the leaves gain in elasticity. But be careful not to overdo it. If water remains in the lower pot for a long time, the roots are permanently wet and root rot threatens. In this case, simply drain off the standing water.

Cause # 2 - Nutrient Deficiency:

Can you rule out water shortage as the cause of the yellow leaves? Then maybe nutrient deficiency is the problem. Angel trumpets are among the heavy-weights that you need to fertilize regularly.

Treatment:

Two times a week, place a commercially available container plant fertilizer in the watering can to ensure a good basic supply.

In order for your angel's trumpet to recover quickly and blossom soon, you must consider the nutrient requirement of the plant at different times: In the first six weeks of the growth phase, the plants need above all nitrogen, which is contained in special growth fertilizers in sufficient quantities. At the beginning of the flowering phase, you then switch from growth fertilizer to potassium-rich flowering fertilizers. Note, however, for all variants of fertilization, the dosage recommendations of the manufacturer.

Cause # 3 - Spider mites:

Do you recognize a yellowish, net-like coating on the leaves of the angel trumpet? This is a clear symptom of spider mite infestation. First, the young leaves are most affected at the shoot tips. If the treatment stops, the spider mites quickly attack the whole plant and gradually destroy all the leaves. Act therefore immediately!

Treatment:

If you detect the disease early, it may be sufficient to remove the affected as well as the immediately adjacent leaves. If the angel trumpet is in the full sun, a change of location makes sense. Spider mites love warmth and dryness. If the reticular surface shows up again on other leaves, you should resort to stronger but natural means. We can recommend you for example the ready-to-use rapeseed oil spray Naturen pest-free (e.g., available here). Otherwise, you can also mix 1 liter of water with 250 milliliters of rapeseed oil and then spray the affected plants twice a week. The oil clogs the respiratory openings of the spider mites so that they suffocate.

Summary:

  • pour more if the plant is too dry
  • fertilize regularly
  • Check plant regularly for pests
