They are dying that quick? That does not sound right. Go over a cklist of things that can be a problem.

Mulch - make sure that you have enough mulch so the soil stays moist, not wet. Otherwise you can get a case of root rot.

Water - This could be your problem. Water more frequently certain times of the year... like at the start of the summer and reduce the watering in the Fall. Watering is critical during the first year! Roots grow slowly so try not to let the root ball dry out. Water the root ball area directly, not its vicinity (the roots may not have grown enough to reach the location where you water). Develop a habit to always water by hand or with your irrigation system. Get a moisture sensor at Lowe's or HD to ck how humid it is underneath. Or just poke your finger 1-2 inches deep and see how it feels. It should feel moist not be wet. The roots grow shallow, in the top 2-3 inches so be careful when testing.

Plant location - windy areas dry the soil faster. Too much sun in that area has the same effect.

Soil - if you have clay soil, you may need to use raised beds with azalea/camellia soil. Azalea roots cannot break thru the hard clay soil as easily as other plants can. Also, remember that the plants need acidic soil (ph less than 7).

Food - azaleas are not big feeders like roses. Provide some pine straw mulch and that should do it for them.

I assume you meant that the plants themselves are dying. If you meant that the blooms are dying then the answer is blooms last about 2 weeks approximately. One variety will bloom ahead of others for that long then the other variety will start and so forth. And in your area, that may be all you get. In the south, there may be more flowers again in the Fall. Encore Azaleas and a few others will bloom from Spring to Fall (but the fall bloomage is always the best). The tags on the plants should have discussed that issue. Ck with the nursery where you bought them for questions. They may be able to tell if the ones you got will bloom again. Luis
