A high level of salt in the soil can affect the process of osmosis that can be the reason for plant wilting. Wilting can also lose turgor pressure.
  2. Lack of roots development. Roots are the heart of the plant. So you should take into consideration that the roots are developing well. Small pot and container are the cause of root bounded.

You know the reason for the dropping and falling leaves. Now you should also know what steps you should take to treat the plant.

1. Solution for Over and Under Watering

Over and under-watering generally show the same symptoms (wilting). So it is a little bit difficult to confirm that the symptoms are for the overwatering or under-watering. Let me simplify it.

If the soil is dry and your rubber plant goes limps and become vigorous after watering. The cause of leaves dropping is under-watering. If the soil is wet or damp and plant leaves dropping. The cause is overwatering. Yellow and brown colors also indicate the overwatering. Pretty simple, doesn’t it?

How much water you should apply?

I think the answer will vary if you ask the question to a different person.

But I will give you quick tips. Always apply a large amount of water. Flush the soil with water. Why did I tell you that? Plant nutrients do not remain available form in the soil. Water will dissolve them. If you apply a small amount of water, a small amount of the nutrient will dissolve. That the reason I have told you that.

But overwatering can harm your plant. That’s why you must have a very good drainage system. Drainage holes will help to leach out the extra water. Extra water will come out with extra salt that will help to balance the level of salt.

Don’t follow this method if your plant pot doesn’t have better drainage facilities. Stick deep (about 2 inches) a wood dowel rod into the soil. Observed the rod that it comes out in wet or dry. This simple test will help you to decide when to water your rubber plant. Apply 1 or 2 inches of clean and room temp water if the surface soil remains dry.

2. Solution for Root Development and Drainage Problem

To know about the health of the root, you have to remove the plants from the pot. If the roots are bounded, repot the plant in a larger pot.

You know:

Rubber plant likes good drainage. Get off the sick plant’s root ball from the pot and let it dry for a few minutes. Fill a larger pot with the fast draining and well-aerated potting soil.

You can mix peat, pine bark, and coarse sand with a 1:1:1 ratio and also can buy potting soil. Further, don’t forget to consider that the pot has a good drainage system.
