| I live in Las Vegas, NV, and I have 3 potted roses that were formerly in the SF Bay Area. Summer here is extremely hot and long and I kept them mostly in the shade. I noticed their older leaves were chlorotic and gave them some liquid-dissolving fertilizer. Several days later their older leaves started to turn brown around the edges and dying off. Their younger leaves go from bright green to dead without turning brown. They just turn crispy and die off while still green. I also noticed the stems are an unhealthy green, then turn brown green, then black. This has been happening to the stems one by one. Is my diagnosis correct or is something else? Is there anything I can do to save them? Would transplanting help or would it stress them even more? Would flushing them with lots of water help? They are in 10*13 pots, how often should I be watering them? I have attached some photos. They belonged to my beloved fiancee who recently passed away and they are very dear to me. Please help. |

| What you did wrong was feed them at the worst time. What you can do is flush the soil clean of fertilizer by watering the pot till lots of water flows out of the holes on the pot, then allow the pot to properly drain till the soil is moist, not soggy. Prune off all dead and damaged parts and remove damaged leaves. keep the plant in a cool and shaded place in your house till the buds start to produce new foliage. When the weather gets better and not so darn hot, you can put them out again. |

| I agree with noacceptance, you should never fertilize or spray an already stressed plant. The key to their recovery now is water, Water, WATER! Flush them right away and keep them well watered and wait. I don't recommend taking roses inside but definitely some shade would help. If possible put them somewhere where they will only get some morning sun and are shaded for the rest of the day. |

| I have nothing to add to the previous posts about what to do to help your roses recover. Don't fret about it too much - we all make mistakes in wanting to care for our roses too much but it doesn't yet look like the rose is dying. These leaves are toast, but the canes look healthy from what I can see and they'll probably put out new leaves if you can water them sufficiently, and maybe provide some afternoon shade (putting a lawn chair over them in the hottest part of the day can be a strategy if they're in the ground). Heartiest sympathies as well on your fiancee who passed away. It's a lovely tribute to her to care for her roses, and I'm sure she would appreciate the intent as well if you were to add to these roses including possible replacements should these run into further problems down the road. Hope this helps! Cynthia |

| Thank you all so much for the advice. I plan to keep them well-watered, though I am worried about overwatering. How do I know if I'm overwatering? I am also torn as to whether to take them inside. We have at least another 2 weeks of 95-100 degree weather coming here. What could hurt them if I took them inside? Then again they've lasted all summer in over 100 degree weather and would probably be surviving fine if I hadn't fed them. One of them definitely looks like it's going to make it, as I see new growth at one cane tip. The other two I am more worried about because I don't see any new growth and all the cane tips are black. and the nodes on the cane are crispy and break off. |

| Personally, I would keep them outside. But I would check for a spot that maybe gets and hour or two of morning sun and then shade the rest of the day. I would also check to make sure they are not getting radiated heat off a wall or window near by or even the ground they are sitting on getting too hot. Remember as we move away from the summer months, the position of the sun changes too and a previously cool place might be heating up. |

| I agree with posters above, keep the rose outside in mostly shade, giving it some morning sun would be perfect. I just wanted to add some advice for the future once your roses do recover. When the temperatures are above 90 its likely your roses will need to be watered daily. The key is to make sure they drain well, moist soil is good, but soggy soil is not. If your pots are sitting in a basin that holds water at the bottom of the pot remove it, let them drain completely. Watering daily is especially true if they are in a clay or ceramic pot that retains heat. I prefer foam or plastic pots in my heat. In the future when you fertilize a potted rose you want to use fertilizer at half strength, unless it is fish fertilizer which you can use at full strength. I'm betting your roses will recover nicely. |

| You can water daily or twice daily or more, as long as the water runs out the drain holes & doesn't pool inside the pot. The more water, the faster you'll flush out the excess fertilizer. You can clothes pin a sheet over them for a week to shelter them from the hottest sun if you don't have a shady place, but I agree with everyone else--roses HATE indoors--indoor air is often drier that the driest desert air outside. Hang on, cooler weather is coming & I hope all of your plants recover. Just cross your fingers & keep up the supportive care. |

| The problem with bringing them inside is that most homes are much dryer than the outside, even in hot and dry climates. And roses need sunlight to produce food. They won't get enough of that indoors. Roses placed in a window are getting filtered sun and not the full spectrum of light they need. It's better to keep them outside and in partial shade than inside. I know that there are some people who have had some luck with wintering roses inside but that is the exception and not the rule. Roses are not house plants and always do better outside. |
|
| So as long as the pots drain well, there is no risk of overwatering? Because even though the air is really hot and dry here, the soil in the pots stays moist for days. Yesterday morning I soaked them very thoroughly and this morning the soil was still wet. |
|
| If you soil is moist there is no need to water them. |

| Hi, I have a few questions... How long has it been since you moved the roses from S.F to NV? Do you know which roses you are growing? How big are your rose bushes? What type of potting soil are they growing in? Everyone here has a generous nature and will help you save your roses. Carlota |
