You say they don't look too good, but I'm not sure what that means. Glads do need full sun and plenty of water in areas like yours that get very high temperatures. Blooms also depend on the size of the bulbs you bought to start with. Small bulbs, which are often those sold in bulk packages in home stores, aren't always large enough to really bloom well. It's best to buy the largest bulbs possible and plant them four to five inches deep. As the flowers fade (assuming they will bloom eventually--you don't say how long ago you planted them, but they should produce some type of flower eventually) clip them from the plant. Leave the foliage intact.
