Here are a few great tips to take into consideration when setting us your container garden. In no particular order they are all helpful and easy to implement.
Plants: Pick plants that are going to look good through out the season. This is not the time to plant something that will die in 3 weeks and then need to be removed. Be concerned about the type of climate the potted plants will receive. Don't put shade tolerant in a sunny location and potted plants that need full sun in a shady spot.
Pottery: Pick planters that compliment your home or patio area. If you home is brick and traditional don't put metal contemporary planters out front. It's not that it will look that bad just kind of off a bit. Make sure they have drain holes so that whatever you plant will have good drainage for the roots and they won't sit in standing water.
Watering & nutrients: The main thing all containers need is added water. Since the plants are not placed directly into the ground the pots need you make sure you keep the soil moist. If you are going to travel try using our water Ollas. Big containers are easier because the soil will stay moist longer. If your area is windy the soil will dry out faster. Be sure and use a fertilizer since the roots can't reach the ground soil. This makes sure that your potted containers look lovely all season long.
