Leaves turned dull bronze and dropping, noticeable webs appear.
The most likely culprits are red spider mites. They are most active between March - October and love dry environments. Take the infected plant out immediately. Make sure to check all your other plants for cross contamination. Remove the plant from the pot and wash out the soil until the roots clean. Clean your pot thoroughly. Repot the plant in fresh soil and keep quarantined until the plant is re-established and new growth appears. Ensure the soil is kept moist to avoid new infestation. Return the plant to its original place once you are confident the problem has been conquered.
Scales or shell-like bumps on plant stems and the underside of leaves are visible. Sticky, sooty deposits on stems and leaves.
This is caused by the scale insect. If you catch the infestation early you can simply remove it with your fingernail and wash the stems with diluted washing up liquid in lukewarm water. Use 1tbsp washing up liquid to 4L of water.
