I work at a nursery and people ask me all day long "What's wrong with my plant?!" Here are some tips that can help with the most frequent problems I see.
1) Know what plant you're dealing with. Look up the plants scientific name (the botanical genus and species) so you know exactly how to take care of it. This will allow you to properly execute on the next three tips.
2) Stop over and under watering your plants. 99.9% of plants suffer and die from incorrect watering.
3) Feed your plants. Yes, plants need food just like humans. If the plant is low on nutrients in its pot or soil, you will probably have to feed it with organic matter and/or fertilizer (preferably organic). You'll see three numbers on a bag of fertilizer like this: 2-4-2. The first number is N, second P, third is K. Here is what they mean:
N (Nitrogen)- Helps with new green growth like leaves and stems
P (Phosphorus)- Helps with flowering/seed/fruit production and promotes root growth/health
K (Potassium)- Increases disease resistance, drought tolerance, and fruit/flower quality
4) Get your plant the right amount of light. You can figure this out from years of trial and error, or you can just look up the scientific name of the plant to see how much light you plant needs
-Full sun= 6-8 hours of direct sunlight per day
-Part sun/Part shade= 4 hours of direct sunlight per day or filtered sun all day long
-Full shade= only shade or well-filtered sun, no direct sunlight.
I hope this helps!
