One possible reason is over-fertilization. Here's what I do with my dahlias: 1. Fertilize early in the season (but after shoots appear above ground) and again 3-4 weeks later. 2. DON'T fertilize right before or during their blooming, but provide plenty of water and deadhead or cut blooms. 3. After blooming is completely over, fertilize again and let them build strength in their tubers for next year.A more specific reason is too much Nitrogen fertilization. Use low-nitrogen fertilizers (like 5-10-10). Avoid the high-nitrogen water-soluble spray-on fertilizers (for Dahlias, flowering vines, and very tall-stemmed flowers like sunflowers). Also avoid using too much compost; add shredded pine bark instead to help break up hard clay soil, or as a winter mulch (but remove in spring). Lowering the Nitrogen you feed them will also help them develop stronger stems.

Also, of course, make sure you water them enough (only AFTER shoots appear). Depends on cultivar, but I've found it hard to over water dahlias and cannas.

Any plant that has 'COLOR' requires at least 6 hrs of direct sunlight per day, the more the better (usually, depending on the cultivar). The above-mentioned recommendation for a lower N2 is spot on, you also should try a 'bloom booster', or 'flowering plant' fertilizer', that would be one with a higher % 2nd number, i.e. 10-20-10. The 2nd number is the % of Phosphorus (by weight) which is essential for budding & flower blooming.

There are a few reasons a daffodil might not bloom.

  • The clump has not been divided in a while, and there is not enough space/nutrients for a full bloom.
  • The clump was divided when the flowers were blooming, so that the bulbs did not store enough energy for the next year's blooms.
  • These plants grew from seed and are not yet old enough to bloom (it takes 5-7 years for a daffodil grown from seed to produce a flower).
  • The plant is too shaded. To bloom the plant needs to be in full sun or partial shade.

There are many reasons for daffodils not multiplying (by bulb).

The two most common are:

  • The clump has not been divided in a while, and there is not enough space/nutrients for a full bloom.
  • The clump was divided when the flowers were blooming, so that the bulbs did not store enough energy for the next year's new bulbs and blooms.

  • The plant was overdosed with nitrogen fertilizer, so that it produces lots of green leaves, but very few, if any, blooms.

Seed from species will come true to type and can take a few years to produce flowers. Hybrids will not come true from seed so are multiflied by various manipulations of the bulbs.

Does a rose plant reproduce sexually or asexually?

Daffodils generate seed that are later fertilized by pollen to create new daffodils. This is a form of sexual reproduction. Another way daffodils reproduce is by producing bulbs called bulbils which can be planted by gardeners. This is an asexual form. So yes, daffodils can reproduce both asexually and sexually.
