I planted some bulbs recently (within the past three to four weeks), including iris, tulips, muscari, anemones and daffodils. Some of them (iris and muscari) are starting to come up. I think the weather is fooling them. If another freeze comes (or even if one doesn't) will they come up again in the spring and bloom? Should I cut off the leaves coming up or let them do their thing? Please help! Thanks!

I've got the same thing happening. My bigger worry is if my fruit trees start growing. This is what happens when we have summer weather in winter. I keep my plants watered and well mulched so if we do get a freeze they will have some protection. DO NOT cut the tops off. You also might consider getting some row cover to protect them.

I've had this happen a lot of years and everything seems to work out. Sometimes we'll have trees, etc, bud out & then get a freeze & all turns out ok.
