Proven Ways to grow flowers and food.
1. Seed
Nature hates a gap. That’s why weeds fill in every nook and cranny available to them outdoors. Sprinkling desirable seeds outside as the snow thaws on the south side of your home or Greenhouse Garden this spring lets you copy nature’s best efforts. Inside your greenhouse, scatter seeds on top of pots or flats. A light dusting of soil and a sheet of glass laid flat over trays keeps the humidity high until the seeds grow.
2. Transplant
Once seeds are up let them grow a bit before you transplant them. When each plant has four leaves the young seedlings are strong enough to be moved up individually to a bigger pot. Some plants, like lobelia, basil and onions, thrive best moved together in little clumps. This means transplanting three to four seedlings together into a larger container instead of separating individual plants.
3. Divide
Splitting up mature plants to make more of them is an alternative to seeding. Large clumps of early bloomers like the perennial Primula can be pulled apart right after their early spring blooms finish. Siberian Iris and daylilies have fibrous roots and are best cut apart with a sharp saw or pulled rudely apart by hand at the first sign of green leaves before they start growing too much this spring. Potting these divisions into larger pots on a greenhouse bench lets you grow them up a bit before they are placed permanently back into the garden.
