I have a variety of bulbs that were purchased and stored in a shed for about 5 years. Can they still be planted?
If they were stored in a cool, dry location free from frost and heat, bulbs can be stored for years. If your bulbs are still firm and don't look moldy or feel soft, I would go ahead and plant them and see if they come up. However, the older the bulb is, it decreases in quality.

I have a new collection of daffodil bulbs to fill in and replace some very old ones that are either just too old (some are 50 yrs old!) or have been damaged so that they might perform poorly next year or not even bloom at all. I am not quite ready to plant just yet. Weather conditions are OK but my free time is minimal, also the areas where I want to plant bulbs still have flowers in them. The new bulbs are trying to sprout a little bit. Should I place them in the refrigerator to slow them down? They would only need to be in storage for a couple of weeks, tops. ~ Thank You
For a short time the refrigerator is fine. 40 F will return them to dormancy. I would wrap the bulbs in newspaper or a paper bag. Some of your neighbors/friends may love to have the old bulbs.
Yes, you can preserve your bulbs for planting in the spring. Here's an article with tips on how to save them: https://www.gardeningknowhow.com/ornamental/bulbs/bgen/preparing-bulbs-for-winter-how-to-store-bulbs-for-winter.htm
I have lots of perennials in pots in my garden, I'd like to plant some bulbs in pots in time for spring. Is it possible to plant the bulbs in the same pots my perennials are in. Or should I buy new pots? plants My perennials are begining to die back now and I am planning to dead head them.
I think I would get new pots. Often people plant bulbs in a pot, then plant pansies on top. The bulbs will come through the pansy foliage.
Since your perennials are already established, I don't think I would go digging around them and disturb the roots. If it's a perennial that needs to be divided, you could add some bulbs at the same time you are dividing your perennial.

We don't make product recommendations but here is the general information:
I have a bunch of fall bulbs that I never got in the ground. I live in northern California, should I plant them or try to keep them until next year. If I keep them how should I store them?
Most fall bulbs can be planted anytime before the ground freezes. In zone 9, you probably don't experience ground freezing. You don't say what kind of bulbs you have but some, like tulips and daffodils, need a chilling period to produce blooms. Even zone 6 is not consistently cold enough for tulips and they are treated as annuals. I would go ahead and plant what you have. December is not too late.

I am moving and would like to dig up a few of my favorite bulbs and take them. I won’t be able to get them back in the Ground right away. What’s the best way to do this?
This will depend on the bulb. You must dig them up while they are in dormancy, then keep them in dormancy until their specific time to plant. This is dependent on the plant, also.
