Planting
This is a good month for planting roses – both container grown and bare-root roses.
Transplanting
Finish transplanting in the early part of this month.
Fertilizing
You can apply fertilizer to established roses the latter part of this month.
Pest Control
If your roses have blackspot, collect and dispose of leaves as they yellow and fall.
Pruning
Prune during the early to middle of this month. Cut hybrid teas, grandifloras, and floribundas back to a height of 2 to 3 feet, or at least cut the bush back to about one-third to one-half its height. Prune out dead wood.
Watering
Rainfall should be adequate for established roses. Newly planted roses should be watered in thoroughly. If there is no rain soak the soil of the rose bed.
Planting
Continue to plant roses purchased in containers. It is too late to plant bare root roses after the first of this month.
Transplanting
This is not the best time to transplant roses.
Fertilizing
Fertilize when new growth begins. Use a premium quality rose fertilizer.
Pest Control
Regular applications of blackspot treatment should begin as soon as new leaves begin to open.
Pruning
Prune as early in the month as possible if you did not do so in February. It will not hurt your bushes, but your roses will bloom later.
Watering
Watch the rainfall and water plants if necessary.
Planting
Purchasing and planting container rose bushes now allows you to pick out the color, shape, fragrance, and size of the flowers you want since most will be blooming.
Transplanting
April is not the best month for transplanting roses.
Fertilizing
If you didn’t fertilize your roses last month do so now.
Pest Control
Do not wait for blackspot to occur before you start a treatment program. Be on the lookout for powdery mildew which appears as a white powdery coating on flower buds, new growth, and leaves. Aphids may be found at this time of year also.
Pruning
Roses are in bloom now and should not be cut back. Deadhead faded flowers by cutting the stems back to the first or second five-leaflet leaf.
Watering
Supplemental water is usually needed this month. The plants need 1 to 1 ½ inches of water weekly.
Planting
You can continue to plant container grown roses.
Transplanting
Do not transplant roses currently.
Fertilizing
You can fertilize again this month (six to eight weeks after your spring fertilizer application).
Pest Control
Continue to do preventative treatments for blackspot. Spider mites may occur if the weather is hot and dry. You can detect them by placing a piece of white paper under the branch and shake the branch. If you see tiny, moving black spots on the paper then you have spider mites.
Pruning
Other than deadheading and pruning off sucker from below the graft union, no pruning is required this month.
Watering
More water is needed as the weather heats up. Water thoroughly once or twice a week. Avoid wetting the foliage to help prevent disease.
Planting
Container roses can still be planted but require deep watering whenever we go 5 – 7 days without a good rain of 1 to 1 ½ inches.
Transplanting
It is too warm to transplant roses successfully.
Fertilizing
If you did not fertilize last month, you may this month.
Pest Control
Blackspot, mites are still problems this month.
Pruning
This is a good month to prune roses that are not repeat-blooming types.
Watering
More water is needed as the weather heats up. Water thoroughly once or twice a week. Avoid wetting the foliage to help prevent disease.
Planting
Container roses can still be planted but require deep watering whenever we go 5 – 7 days without a good rain of 1 to 1 ½ inches.
Transplanting
It is too warm to transplant roses successfully.
Fertilizing
July is generally not a good month to fertilize roses.
Pest Control
Blackspot, spider mites, leaf-cutter bees, caterpillars and beetles are the most common problems this time of the year.
Pruning
No pruning is required this month other than deadheading and pruning out diseased or dead growth.
Watering
Keep roses watered as needed to maintain a moist soil. Do not allow our roses to wilt before you water them. Mulching 3 to 4 inches deep reduces the required frequency of watering.
Planting
Container roses can still be planted but require deep watering whenever we go 5 – 7 days without a good rain of 1 to 1 ½ inches.
Transplanting
Do not transplant roses this month.
Fertilizing
Fertilizing during late summer is second in importance only to the spring fertilization. Extra nutrients provided now will encourage vigorous growth and flowering over the next three months.
Pest Control
Blackspot, leaf-cutter bees may chew round holes from the edges of rose leaves.
Pruning
It is important to prune roses now to get them in shape for the fall blooming season. Top the bush back to the desired height, remove all dead wood, diseased canes and twiggy growth. Cut each remaining cane back to just above a bud (preferably facing away from the center of the bush).
Watering
Keep roses watered as needed to maintain a moist soil. Do not allow our roses to wilt before you water them. Mulching 3 to 4 inches deep reduces the required frequency of watering.
Planting
Container roses can still be planted but require deep watering whenever we go 5 – 7 days without a good rain of 1 to 1 ½ inches.
Transplanting
It is still too hot to transplant roses this month.
Fertilizing
This is the last fertilization required for this season.
Pest Control
Blackspot, powdery mildew, spider mites, aphids are still active through the fall.
Pruning
Roses should not be cut back this time of year.
Watering
Supplemental watering is still necessary if rainfall amounts are less than 1 to 1 ½ inch every week.
Planting
Container grown roses can be planted this month.
Transplanting
Wait until the weather is cooler to transplant roses.
Fertilizing
No fertilizer is needed for the rest of the growing season.
Pest Control
Cooler, dryer weather will reduce blackspot.
Pruning
Only deadheading and pruning out diseased or dead growth, no pruning is required this month.
Watering
October can be one of our driest months. Water roses deeply as needed.
Planting
Container roses can be planted this month.
Transplanting
Wait until December or January to transplant roses.
Fertilizing
No fertilizer is needed for the rest of the growing season.
Pest Control
Pest problems are diminishing. You will still see blackspot and aphids may sow up on flower buds or new growth.
Pruning
Avoid heavy pruning that would stimulate new growth.
Watering
Water plants if rainfall is not enough.
Planting
Container roses can be planted throughout this month.
Transplanting
After a killing freeze or frost is a good time to transplant roses to a new location.
Fertilizing
No fertilizing is necessary during this month.
Pest Control
Blackspot can occur in winter months but usually isn’t serious enough to need spraying.
Pruning
No pruning is necessary this month.
Watering
Established roses should receive enough water through rainfall. Newly planted or transplanted roses need watering if enough rain doesn’t fall.
