“Who Else Wants To Learn the Secrets of Dealing with Rose Diseases?”
One of the most common problems facing many rose gardeners is rose diseases. Roses can be beautiful, but if they are not taken care of properly they can develop diseases. There are a few signs that you should look out for it you are growing roses. There are no immediate cures for many rose diseases, but if you are paying close attention to your roses you can prevent them from getting rose diseases.
Rose diseases normally fall into three categories: black spots (the most common), rose rust, and downey or powdery mildew on roses. Most rose diseases are treated with fungicide when they are first detected. That old saying “an ounce of prevention is worth a pound of cure”, definitely applies when it comes to roses. To make sure you don’t get rose diseases, you need to implement prevention techniques that can stop rose diseases in their track.
If you grow your roses with other plants (which is a good idea), you need to watch your plants closely to see if you notice any insects or rose diseases forming on them. At the first sign of trouble, you need to fungicide them immediately. If you wait too long and allow the insects of diseases to spread, you could lose all of your roses before they even have a chance to grow.
If you notice that only a few leaves are affected, remove them right away to stop the spread of rose diseases cascading on to your other plants. The good thing about roses is that a new leaf can grow back, but a rose that is completely affected can kill any chance of you having beautiful roses. Lets’ look at some of the things you can do to prevent rose diseases.
Prevention of Rose Diseases
- Roses need to have at least 6 hours of sunlight each day
- Make sure your roses are getting enough water to survive, but not too much water
- Ensure that were you plant your roses has sufficient amount of drainage. You don’t want your roses sitting in standing water.
- Make sure you are cutting off spent blooms (deadheading). You should cut roses down to the first 5 leaf growth.
- Remove any and all dead branches. Also cut off “suckers,” which are red branches that sprout at the bottom of the plant and suck energy from your roses.
- Amend the soil. It should be neutral or slightly acidic. (Use a soil test kit—found at garden supply stores–to test your soil.) If your soil doesn’t meet these requirements, a quick fix is to dig a large hole (at least 3 feet by 3 feet) and put “rose soil” in it (purchased at a garden supply store).
- Make sure the rose is planted well.
- Roses also like to be fertilized. There are as many ways to do this as there are gardeners, but any decent rose fertilizer should do as long as you follow the directions.
In addition many rose growers swear by planting a banana peel under the rose, or mulching peels in to the soil near the rose.
Signs and Symptoms of Rose Diseases
Black Spots on Leaves – This rose disease is commonly known as black spot. Black spots appear as circular with fringed edges on leaves. They cause the leaves to yellow. Remove the infected foliage and pick up any fallen leaves around the rose. Artificial sprays may be used to prevent or treat this kind of rose disease.
Flowers that don’t open or are deformed when they do open up – Thrips could be the reason behind this problem. They are slender, brown-yellow bugs with fringed wings that also suck juices from flower buds. Cut and discard the infested flowers. Orthene and Malathion may also treat this problem.
Weak and mottled leaves with tiny white webs – This is caused by aphids. They are small soft-bodied insects that usually brown, green or red. Often clustered under leaves and flower buds, they suck plant juices from tender buds. Malathion or diazinon spray may help roses to survive these bugs.
Malformed or stunted leaves and flowers – This is caused by spider mites. They are tiny yellow, red or green spiders found on the underside of leaves where they suck juices. The application of Orthene or Isotox may help in treating this infestation.
Stunted or malformed young canes – Known as powdery mildew, this is a fungal disease that covers leaves, stems and buds with wind spread white powder. It makes the leaves curl and turn purple. Spray with Funginex or Benomyl to treat this fungal disease.

Your Questions About Care For Roses In Spring
Jenny asks…
What should I plant this spring in my outdoor garden?
I’m in the 5A-6B plant hardiness zone of Canada. I have a garden on a slight incline about twelve feet wide and five feet deep. It is currently quite rocky, it appears gravel was added underneath canvass for drainage (I assume) and then dirt dumped over it. Should I dig all of this out and start over? There are some perennials, (rose bushes – very ugly) that I’d like to pull out, and hostas I planted last year. What type of shrubs, perennials and flowers would do well in this area? I am looking for easy care type stuff, but I like pretty flowers. I also prefer wild flowers or those that look wild. I do not like the rose bushes, they are very difficult to make look pretty and are quite thorny making access to the rest of the garden difficult as they are so overgrown. Any tips for the small hill garden would be appreciated as well.
MrRoseGarden answers:
You could make the area into a rock garden. Suggestions for plants: cranesbill, stonecress, bellflower, gentian, lantana, salvia, sedum, diasca, scilla, onamental onion, crocus, allium, fleabane, phlox, violas, and herbs. Incorporate a few large rocks or use smaller ones as an edging. Removing the roses sounds like a good idea if you don’t like them. Plant something that will make you smile every time you see it. Good luck.
Mark asks…
How should I take care of my mini rose bush?
My boyfriend got me a mini rose bush for Valentines Day (I do not celebrate the holiday and I told him that but he got me it anyway :/ ). He doesn’t know what kind of rose it is but the blooms are red and about an inch in diameter and the leaves are small and have have jagged edges. It is not very fragrant. I really want to take good care of this little plant; I’ve done research but it is all too generic, and I want to confirm what I have gathered.
Here is what I have gathered:
Roses need humidity.
Mixing dried used coffee grounds with the soil will help it grow.
They need indirect sunlight.
The roses should be trimmed when the blooms die or once in the spring and once in the fall.
They should be kept outside spring thru fall and inside in the winter.
Here are the rest of my questions:
What kind of mini rose is it?
Where should I replant it outside?
Do I need to replant it outside?
How can I tell when my flowers need a bigger pot?
When do I need to water my mini roses?
Can I simply spray my flowers with water instead of using a pebble tray?
If I can spray the flowers with water instead of using a pebble tray, how often should I spray them?
Those are all of my questions……for now. Please either confirm or disprove what I have learned thru research and answer my questions. Help me take care of this precious little plant!!
MrRoseGarden answers:
If you have a place, plant it outside this spring and grow it there… It will be much happier…
Never spray a rose plant with water.. That invites black spot mold disease…. Stick with the pebble tray for the time the little rose is in the house….
Water for a rose is easy… They like moist soil, but never soggy… The saying is that Roses hate having wet feet… Which means if their roots get waterlogged, the plant dies……so whatever pot it is in MUST drain freely… And don’t let the bottom of the pot sit in water in the pebbles, either!!….
A miniature rose bush is a mini ROSE, not a mini BUSH… It will grow, outside, to the size of a regular rose bush… Maybe three or four ft tall and a couple feet wide… And be loaded with perfect tiny mini roses…. I have a pink one that is my favorite in the garden!!…. If you’re in a zone south of zone 5, nothing special is needed to keep it thru winter… They’re very hardy….
Otherwise, treat them just like a big rose…. Food, water and all sun… Prune in early spring when they’re four ft tall, down to about 18 inches tall and watch them go right back up by fall…
If you cannot plant outside, use a basketball sized pot for it this spring and keep it where it gets all day sun, but maybe a little afternoon shade, so the pot and soil doesn’t get too hot…. Stay up on it’s water … Be sure the pot drains well if it rains hard, too!…. Then, when winter comes, let it get frost nipped to where the leaves start falling off…. Then bring it in to a COLD area like a storage room or garage, take all the leaves off, wrap the pot iin a good heavy blanket , add a cup of water when the soil feels very dry, about every weekend or so, maybe….. But do let it have the winter to ‘rest’…. Chilled… Don’t keep it in the house and expect it to bloom all winter…. There’s just not enuff sun and it will stress the plant to try to live without resting…. When spring is coming, bring the pot into the house, warm it up, give it a bit more water and then wehn the last frost is gone by, take it back out and feed it….
Happy rose growing!!…
Chris asks…
Is it ok to send red roses to a girl that you are not officially in a relationship with?
I started talking to a girl last spring. We met through a friend but with school and work we have not gotten a chance to actually meet face to face yet. The thing is we have become very close while talking online and over the phone. We both seem to have feelings for each other and have said “I love you” back and forth a few times.
So with that I would like to do something nice for her for Valentine’s Day. I thought sending flowers would let her know how much I care about her. The thing is I’m not sure if red roses are best considering how those are supposed to be a symbol for love and even though I do feel like I love her I don’t want to scare her away. Any suggestions would be great. Thank you.
MrRoseGarden answers:
As long as she isn’t in a relationship with someone else, it should be fine…..send her white roses or fire & ice roses….(or puple, yellow, etc…..) don’t send red if you don’t feel comfortable….

Thomas asks…
Miniature roses?
At my local nursery i was given a pretty miniature (tea) rose as a gift from the store. It’s in lovely condition but the problem is…i have a terrible track record with these particular plants. I need good advice on how to care for this plant and how to keep it alive for longer than a couple of weeks. Also..i would like to know if it’s possible to plants it outside and if so ..what kind of conditions would it need to thrive out doors.
So i need advice on it’s care for living indoors over this winter, and what it needs to live in the garden if it’s possible to plant it out of doors this spring.
MrRoseGarden answers:
Most plants die from too much care rather than from benign neglect. Water this rose sparingly. Water till water comes out the bottom of the pot, let it stand for a few minutes, then pour off the excess. Do not water again till the soil feels dry to your second knuckle. Better that the plant should even wilt a little than to overwater. Feed it once a month with an all-purpose fertilizer. Don’t overfeed – we’re going into winter when days are short and light levels low, so the plant will not be actively growing till spring. Give it all the sun you can; roses want full sun.
Yes, if it lives through the winter you can plant it outside in spring. Mini roses are hardy to Zone 5 but not 4. Good luck with y our rose!

Your Questions About Care For Roses In Pots
Carol asks…
I would like to have info on how to care for some miniature roses inside. They came in tiny pots in oasis.?
Should I move them to a larger container? If so what should I plant them in? In terms of soil.
MrRoseGarden answers:
If they came in pots of oasis then they are most likely fresh cut roses. You really can’t move them to a larger container or repot because they are not plants. You can plant fresh cut roses but this is mainly done with roses from the garden.
Steven asks…
How should I care for a potted rose?
I have a rose bush potted in a 16″ diameter plastic pot (with ample drainage) on my elevated deck so the deer can’t eat it. How do I keep it healthiest? Will it eventually become root bound? What’s the best way to care for a potted rose?
I live in Washington State. We had a deep freeze in December and I brought the rose inside for that. It’s been potted for two years now.

Sharon asks…
How do I care for potted rose plants?
Hello, I received three potted rose plants (the plants are about 18 inches tall, in about 5 inch pots) as a birthday gift. I only have a balcony and do a lot of growing of herbs like basil and mint, but I haven’t tried flowers yet. What do I need to know to keep the roses healthy, such as fertilizer, re-potting (and when), pruning, watering, etc.? I get good sunlight, with eastern and south-eastern exposure. Will these roses live in pots? Thank you so much for your help!
Good points, everyone –
I live in Los Angeles and the weather has been sunny and in the 70s or higher (we are lucky out here!). I usually don’t bring any plants inside during winter unless it is supposed to get to freezing or close (which didn’t happen this year).
As for what type of roses–unfortunately I don’t know! They were a gift from my someone who doesn’t know that much about plants, and they don’t have any tags or information on them. I could call the store though! They have pretty small to medium blossoms and pretty small leaves–that doesn’t tell you much I’m sure but that’s about all I got! 
MrRoseGarden answers:
It would help if you mentioned where you lived, so we know the climate….Yes, you can grow roses in pots.Currently I have a rose bush growing in a west facing window in my house If yours are in 5″ pots only, you need to repot them asap. I would suggest going up to a 12″ pot to start. Get some good potting soil, Miracle Grow brand(Wal Mart) if you have access to a greenhouse grower, go there and buy some from the grower. Buy the best, it is worth it. The roses will do best if they get full sun as much of the day as possible. Treat them like a house plant for the most part, watering and fertilizing occasionally. I live in Minnesota, so I will be putting my rose outside once it warms up for the summer. As far as pruning, you can cut them back as you feel necessary. I wait until after the flower is spent, and then cut back about 10-12″ of the flowering stem. New shoots them come out from the cut.
Michael asks…
Watering roses in large pots.?
Just bought 2 rose bushes about 18″ high. put them into large pots. How much water should you give them and how often. They do have several bulbs ready to open. I am new at caring for roses.
MrRoseGarden answers:
You’ve received some good information here. I have to disagree with “renpen” though. I used to maintain interior plants for very large corporate accounts. We were not allowed to use the water meters. During a workshop, we experimented with these meters. Most of us who dropped the meter into a watering bucket (full of water) the meter read “dry”. These things measure the salt or something in the soil. Not very reliable. There is nothing more reliable than sticking your fingers deep into the soil and “feel” how much water your rose needs. They will tell you. It all depends on the conditions they are in.
Good Luck! I wish my roses were ready to bloom now. Not for a few more months for me!
Laura asks…
How should I care for a patio rose this winter?
I’ve just bought a potted patio rose in memory of my Nan but am now unsure of how I should care for it this winter.
Do I need to cover it to protect it from the frost?
Or will it be fine to just leave it…?
Would really appreciate some help!
Thanks
I live in Cambridge, England
MrRoseGarden answers:
It depends where you live and what the freezing zone is like. Here in zone 7. I just leave my roses alone and they are always fine when spring rolls around.

Your Questions About Planting Roses In Containers
William asks…
Is it ok to plant roses in a container?
MrRoseGarden answers:
Planting roses in containers is a great way to make them a “portable” addition to your landscape. Choose an 18″ container with good drainage, use quality potting soil, fertilize and water as necessary. I have a rose tree that’s been potted for approximately 4 years.
James asks…
I live in Las Vegas, what is the best way to plant roses?
I have the roses in a one gallon container, but know little about the transplanting, watering and best rose food.
MrRoseGarden answers:
Las vegas~! Loved it when we were there so many years ago. Best way i ever seen anything grown out there was in very large pots! Keep them out of direct sunlight and water them in the morning, every morning !
Laura asks…
Can you take roses from the yard and plant them in containers?
I recently bought a house and in the back of the yard are a couple small older rose bushes that I would like to put into containers on the front of the house. Is this possiable? or am I stuck with them in the back?
MrRoseGarden answers:
You can move them, but if they are too large then they will not grow in the container. The roots need room to grow and also space to breath. Make sure the planters are large enough. Hope that helps you out!
Linda asks…
QUESTION FOR ROSE LOVERS; Can roses be planted in a container and transplanted in the fall?
I have a bare root rose that is being transplanted from another home to mine. The ground is too wet to plant and I’m afraid that if I wait it will damage the root. If I plant it in a large container will it be safe to replant in the fall?
MrRoseGarden answers:
Yes!
John asks…
Planting rose bush in a container…?
I know I need good soil, maybe fertilizer, etc. I am wondering about exactly WHAT to put in the bottom of the pot for drainage. I have a large rubber pot, made from old tires and it’s gonna be great for the bush, but what do I use for drainage? Can I use styraphome packing nuts? Strange question, but I have a lot of those. I also have a big limb that blew into our yard the other night with a storm. Should I break it apart and use the leaves, small limbs for drainage? Please answer if you know about roses. They are hybrid teas. Thanks.
MrRoseGarden answers:
I generally put gravel in the bottom of my pots, whatever the plant type and even if it’s got a drainage hole.
