QuestionI have a wonderful lady, who planted some gorgeous little roses in two pots. I read your reply to another question, and understand that potted roses (indoor) are a balancing act.
I overwatered them. Three times I believe. They are starting to die; yellow leaves... starting to get brown stems. Is all lost?
AnswerNo, You haven't killed the roses, just make them sick. Cut the stems right back to the green colour. You can cut back to 2 inches as a rose will grow back from just 2 inches. The soil may be depleted of all nutrients so use a slow release fertilizer such as Osmocote 14-14-14 and give the rose half a teaspoon sprinkled around the base. Then place the roses where they get the most light. Warmth is not necessary but lots of light is. Wait until the soil is dry before watering. Place the pot in a saucer with the water in it and wait until the top of the soil is damp. You then should be able to wait about 5 days before the rose needs water again preferably even longer. It is better to let a rose plant dry out then water it with kindness. It is usually the dry heat in a house plus overwatering that does a potted rose in. To get potted roses through the winter it is best to place them in a room that is the coolest in the house. Winter sun really isn't strong enough to make a rose flower. Next spring when it warms up, cut the rose back again by a third, add more Osmocote (it lasts six months) place it outside in the sunshine and then bring it in for the night. When the weather has no frosts, place it outside where it gets no hot afternoon sun, and it will put on lots of new growth and flower well for you.
