| I have Siberian Iris it did not bloom this year. do I need to dig up and separate? if yes how and when |
| Unlike other iris that will stop blooming when overcrowded, Siberian Iris plants tend to be tough and longlived; once you have them in the ground, you may not have to divide and replant for seven years. They also bloom profusely; you won't get more than two or three blooms per stalk, but you may get 50 or more stalks from a well-established plant, so the total effect is striking. If your plants are not flowering, double check their growing conditions. They need full sunshine, humusy soil, and lots of water during the growing season. Feed them in early spring (use a 10-10-10 or 20-20-20) to promote healthy growth and lots of flowers. Try this regime next spring and they should bloom for you. If not, you can dig them up, amend the soil, and replant. Enjoy! |
