Ideally rose shrubs\nneed to be spaced so there is at least 2 ft of distance between the outer\nfoliage. Roses need to be spaced far enough apart so that you can prune them\nwithout being scratched by thorns and so there is enough air circulation to\nkeep down diseases. The closer the roses are the more they have to compete for\nresources and the less they will bloom.\n\n\n\nThere are literally thousands of varieties of roses so you will need to research the specific height and width of your rose when it is at full maturity so you can space it accordingly. Generally speaking the bigger the rose, the more resources (sunlight, water, access to nutrients) it will need. \n\n\n\nWhat about Spacing Container\nand Miniature Roses?\n\n\n\nThere is less of a need to place miniature and container potted roses so far apart because they are not competing for the same resources in terms of nutrients and water (as they are confined to a pot).\n\n\n\nHowever you will need to make sure each individual rose receives enough sunlight (6 hours per day, preferably more) without shading one another with their foliage.\n\n\n\nAnother important perquisite is to ensure there is enough room for air to circulate freely around the leaves. If roses are too close together they can create their own micro-climate of still air and slight higher humidity which can increase the likelihood of fungal diseases.\n\n\n\nIf there is sufficient air flow and your container roses are\nnot casting shade on one another then you can place the roses so that the outer\nfoliage is around 6 inches apart without any problems. \n\n\n\nBe mindful to factor in the extra growth that roses put on\nin the summer and adjust the spacing of your containers if you need to.\n\n\n\nConsiderations when Spacing Roses\n\n\n\nPruning and Deadheading\n\n\n\nPerhaps the most important consideration when spacing roses is whether you can move around the bush freely. Every year you need to prune your rose in early spring and then deadhead the spent flowers throughout the summer to get the best floral display from your rose.\n\n\n\nYou will need room to access the rose at different angles to\nbe able to cut away dead wood and make precise cuts above the bud without being\nscratched and attacked by thorns!\n\n\n\nIn summer, deadheading the spent blooms can become a regular job in order to redirect the rose\u2019s energy from producing rose hips (seeds) into producing more blooms so make sure you can move around your roses easily.\n\n\n\nIt is also good practice to space roses so you have room to inspect leaves for insects and fungal disease out breaks and to treat them with sprays or clip them off and dispose of them accordingly.\n\n\n\nIf you clip off diseased leaves make sure you throw them away or burn them. Do not place them in the compost heap as fungal diseases can lie dormant and launch another attack when you eventually spread the compost around your garden.\n\n\n\nMulching and Fertilizing\n\n\n\nRoses love an application of mulch around the base of the\nplant to improve soil texture, retain more moisture, add fertility and cool the\nroots in summer.\n\n\n\nSome rose growers like to add compost mulch around their roses\nat the start of the season and again at just before winter to insulate the\nroots from the worst of the winter cold and give your rose a head start next\nseason.\n\n\n\nYou need to leave enough room so you can distribute mulch around the rose bed so that the layer is two inches thick and crucially, not in contact with the rose wood that is above ground as the exposure to moisture from the mulch can cause rot. \n\n\n\nMake sure that you leave enough room to throw down some\nmulch around your rose canes but ensure that you can arrange the mulch so that\nthere is at least a 3 inch radius of bare ground around the rose canes.\n\n\n\nFertilizing also is a regular job in the spring and summer\nwith some rosarians adding fertilizer in the form of granules or fish emulsion\nup to once per month. \n\n\n\nKeeping your roses a good distance apart means each of their individual root systems are not competing with one another for nutrients from the soil and from additional fertilizers. \n\n\n\nThe more space you can afford to give your rose the more it will be able to obtain all the nutrients it needs to stay healthy, disease resistant and produce the best possible floral display.\n\n\n\nYou also need to bear in mind how close your roses are to other plants and even trees as roses are very heavy feeders requiring lots of nitrogen, phosphates and potash to produce flowers and thrive which is why fertilizing and spacing your roses generously is so important.\n\n\n\nAir Circulation\n\n\n\nRoses like a happy medium when it comes to air flow. If your\ngarden is too open and windy then it will sap the rose of moisture from both\nthe leaves and the soil, potentially leaving the rose dehydrated. \n\n\n\nHowever if the roses are placed too close together and the\nair is consistently too still because of an enclosed garden then this can\nincrease the likely hood of common fungal diseases such as black spot and\npowdery mildew. \n\n\n\nBlack spot and powdery mildew are more prevalent in warm,\nwet and confined areas and will spread from rose to rose if they are placed to\nclose together.\n\n\n\nBy giving your roses a good amount of space and keeping a\nclose eye on rose leaves in the summer you can catch fungal disease early, clip\nthe affected leaves off and burn them or throw them away. \n\n\n\nI must reemphasize to not add diseased leaves to compost as the fungus can remain dormant and launch another attack when you distribute the compost around your garden. \n\n\n\nKeeping your roses a good distance from each other (and from\nother plants in your garden) will help breezes flow through the leaves and make\nthe conditions less favourable for disease.\n\n\n\nSun Light and Watering Between Roses\n\n\n\nThe obvious problem is that roses that are closer then 1 ft away from each other can potentially deny one another of sunlight as the sun moves from East to West.\n\n\n\nRoses need to be in a sunny spot with at least 6 hours of direct sun.\n\n\n\nTake into consideration the movement of the sun throughout\nthe day when planting roses in one area to make sure that each rose will\nreceive enough sun without shading one another at different times.\n\n\n\nThe best thing to do is to sit in your garden reading a long novel on a summer\u2019s day and assess how much light your roses will get!\n\n\n\nOr if you can't spare the time there is a device on amazon that measures not only the amount of sunlight a spot in your garden receives, but also the soil pH and the moisture content of the soil. Best of all it is available for a great price!\n\n\n\nIn terms of watering roses that are close together, the main\nconcern is that the root system of each plant will be competing to draw up\nwater. \n\n\n\nAs long as you apply a mulch at the start of the season composed of organic matter such as leaf mould or compost (which helps retain water) and water your rose with a good soak (approximately 4 gallons per rose) once per week in the growing season, then there will be enough water to go around.\n\n\n\nThe bigger problem with roses in close proximity will be the roots competing for nutrients as roses are heavy feeders and require good fertile soil to be at their healthiest and display the best blooms so make sure you stay on top of your fertilizing regiment.\n\n\n\nSpace to Appreciate your Rose\n\n\n\nThere is also the fact that roses are grown to be admired! So give them their space and they will reward your with a gorgeous floral display. \n\n\n\nLeaving a generous amount of space between roses means that you can get up close and personal to, well...stop and smell the roses!\n\n\n\nThere is nothing more pleasing on a summers day to sit back and appreciate all the hard work you have done in the garden to keep your roses looking their best.\n\n\n\nConclusion\n\n\n\nBy giving your roses around 2 feet of space to the nearest plant you will ensure the rose has enough access to nutrients, water, sunlight, fresh air and enough room for you to prune back and deadhead the flowers.\n\n\n\nSpacing your roses accordingly is an important and overlooked part of rose care. If you are planting new roses, remember to research your variety of rose and find out exactly how tall and wide it grows so you can allow approximately 2 feet between each rose at maturity. \n\n\n\nIf you have establishes roses that are perhaps too close together bare in mind that you can give them a harsh early spring pruning so they don't compete with each other for sunlight and air circulation to the same extent.
