potted knockout roses
Can I keep a knockout rose in a pot and what size pot should I use?
Knockout roses can do quite well in pots. I would not use a pot less than 18 to 20 inches in diameter and at least as deep as a five gallon bucket. I like to give the root system lots of room to spread out. I have some rosebushes and a rose tree planted in some of those rope handled storage buckets or tubs, like found at this link: http://www.agrisupply.com/product.aspx?p=89202&sid=bsf10&eid=Ebsf10&utm_source=bing&utm_medium=cpc&utm_campaign=NB_PLA_AllProducts_BING&zmam=77232640&zmas=1&zmac=2&zmap=89202&utm_content=0CU9k6LK_dc|pcrid|11231445313|pkw||pmt|| I drill holes in the bottom for drainage and put a layer of 3/4" gravel in the bottom to help the overall drainage work well. I place the tubs on a couple pieces of redwood or treated wood, again to allow a free and open drainage area. The tubs are way less costly than some pots. With today's spray paints that work on such plastic materials I can even paint them up with different colored bands or designs to give them a bit of character if I so choose. I use a good amended bagged garden soils mix or potting soil from EKO or Miracle Gro for the planting soils.
