Make sure the container is big enough to allow the plant to grow, you may eventually want to repot it but then again you may not so allow enough space for the roots to develop. Strong healthy roots make for strong and healthy plants and strong and healthy plants withstand pests and disease better than weak plants will.
You will find that plants in containers may need more water than plants that have their roots in the soil. My experience with containers on a balcony, that was fairly high up and subject to strong winds, showed me the soil dried out much faster than the soil in my garden, even when the garden was situated in the same amount of sunlight as the containers.
The plants had less wind protection on the balcony and the roots, unlike the roots of the plants that were planted directly into the earth, could not reach out for water but counted on me to supply it. So check your container plants regularly to see if they need water.
