Rose callendar. Know when to plant.

 

  • March 15th.—Finish the pruning of hardy varieties already planted.
  • March 25th.—Plant new hardy roses, pruning new plants rather more severely than those of the same varieties already established.
  • April 15th.—Finish the pruning of tender varieties, as far as possible, without uncovering completely. Give to all the beds and to any neighbouring pear trees, grape-vines, or other plants subject to fungoid troubles, a good spraying of Bordeaux mixture as a preventive.
  • April 20th-25th.—Uncover tender varieties. Plant any new ones received, giving these slight protection of loose hay for a short time over the tops, and a rather severe pruning.
  • End of April.—Roses generally in leaf.
  • May 20th.—Buds forming. Give a second treatment as above.
  • May 25th.—Earliest roses in bloom, including Hugonis, Scotch roses, Persian Yellow, etc. Apply liquid manure to all the H. P's. and H. T.'s.
  • June 5th.—Hybrid Perpetual roses in full glory. Watch for rose bugs; pick them into kerosene or water, or if very plenty, use the protective spray.
  • June 10th.—Another sulphur-tobacco dusting. Keep after rose bugs. Stir into ground around each plant a trowelful of half bone dust and half powdered sheep manure.
  • June 20th.—Hybrid Teas in full bloom. Continue vigilance for insects, mildew, and black-spot.
  • July 1st.—Another sulphur dusting. Hybrid Perpetuals decreasing. Hybrid Teas also decreasing.
  • July 10th.—Rose bugs gone. Continue dusting for mildew and black-spot; pick up and burn all fallen leaves; keep ground thoroughly cultivated.
  • July 20th.—Hybrid Teas and Teas decreasing. Carefully cultivate and then mulch beds with peat moss or similar substance.
  • August 10th.—General overlooking to get any black-spotted leaves, and to check any insects.
  • August 30th.—Hybrid Teas and Teas, second bloom begins, lasting until frost.
  • September 15th.—Second bloom of Hybrid Perpetuals begins, but usually it is not very plentiful.
  • October 15th.—Prepare new beds for the next spring planting. Rigidly destroy by burning any leaves that show black-spot; dust the remaining foliage.
  • November 15th.—Begin protection after first freezing of the ground.
  • November 30th, or after a decided freeze, cover up for winter, tying down long canes to prevent winter winds from whipping them about.
