Plant Care
All plants, just like you and me, need water and food on a regular basis.
Water the soil, not the leaves of the plants.
It is best to water your plants early in the morning.  Watering mid-day can scorch the leaves and have a tendency to evaporate more rapidly than earlier in the day. Watering in the evening can create a molding condition on the plants.  You should water your plants when the soil feels dry.  Put your finger in the soil up to your first knuckle; if it feels dry, water it thouroughly, otherwise do not water it.
Occassionally, give your plants a feeding of fertilizer.  There are nutrients in the soil already, but they become leached out during watering.  Feed them with a fertilizer every few weeks with a well known brand that has a rating of 20-20-20 or close to it.
