The easiest way to get softwood tip cuttings early in the year is to pot up a stock plant and take it into a heated greenhouse early in the year. Cut it back to around 2 or 3 inches called stooling or coppicing), fertilize every 2 weeks and in 4 to 6 weeks it should provide plenty.
Take another stock plant give it the same treatment but leave it outside (mulch the pot) and you will have nice semi-mature cuttings in July and August. Later on it will also provide good hardwood cuttings.
The easiest way for an amateur propagator to root cuttings is with hardwood cuttings in a slit trench with a cloche. Take lots of these each with several eye's because you probably wont root more than one in five.
Another method called Mounding or Stool Layering involves coppicing the plant then, after it forms a thicket gradually mound up around the new canes (fooling the plant into rooting higher and higher. When the new growth is 6 inches tall mound to half their length. Continue to mound higher and higher as more new growth apears leaving the top bud or two exposed. The following spring wash the mound away and seperate from the parent plant below each clump of roots, then carefully pot up and baby for a while under shade cloth. This method should work with roses though there are no guarentees. Grafted roses when planted 4 or 6 inches deep often root above the graft and thats basicly what we are doing here. You might experiment on different canes with wounding the node or other part (label each cane with what you did so if it roots better you can do that from then on).
Collection of seed should be done after the capsule containing the seed has turned color from green to yellow and then to a dessicated brown. Failure to wait til the seed is mature could greatly reduce the odds of germination.
There are two types of seed germination differing mainly in the stratification (special conditions) required. Tiger lillies should germinate easily as shown below. In February and March with bottom heat, April and May without.
The soil used in your pans should have a coarse, fibrous mix as a base topped off with a sifted finer mix. The best qualities a seed starting mix should have are good drainage, high water retention and good porosity to provide lots of difuse oxygen. At the same time the mix should not lose these qualities through rapid decomposition (fill container 2/3 with potting soil then 1/6 with sifted vermiculite).
Water must be aplied carefully in order not to float the seed.
Place pots in a propagator in which a bottom heat mat is covered with a layer of sand. After watering the seeds, a one inch (or thicker) piece of styrafoam should be laid over them all together to retain heat and moisture. When seedlings emerge remove the styrafoam and reapply it each day. Water well with a fine rose (a rose is the part of a watering can that breaks up the water). There is little chance of overwatering as the soil mix should not retain any water at all. Fertilizing should commence as seedlings emerge.
