Our bulbs were in the Central California lawn when we moved in. We learned of them after our first mowing-They bloomed! I rescued the rest of the Muscari into a dirt planter, in which they grew very tall, but never bloomed. Why? Now that they have gone to seed, what should I do with the bulbs and seeds (They need to be transplanted for more room). Caution not to plant near certain fruit trees: True?
Why Did Our Muscari Only Bloom After Lawn Mowing?

I don't think the mowing really had anything to do with it so much as the variety that you may have. There are some types of Muscari that will actually bloom later than the earlier sping bloomers do--late spring to early summer, in fact. This could be the reason for their sudden blooming. If you moved them during flowering, this would also have affected the blooming cycle, which is why they stopped. In addition, the soil in your planter (if different from where you dug them up) could be lacking phosphorus, which promotes blooming. No worries though, they will return again next season.
I have not heard of the fruit tree thing. Never had any issues with mine. When collecting seeds, you'll need to wait for them to dry and wither. When they are ready, the pods start to turn light brown and papery. Once dry, you can plant them as you would any other seeds and once seedlings are big enough, you can transplant in the garden or container. However, they don't usually bloom the first year so you'll have to wait until the plants mature. Generally, you would lift the bulbs in fall though you can either transplant now or store them throughout winter. Warmer climates can simply leave them.
