Ground temperatures have been over 50 for well over 6 weeks. My first spears started to come up a month ago. I fertilized over the summer with compost and at the beginning of this Spring I put about an inch of compost over the asparagus. Is it recommended to dig around the crown to see of there is new growth? Maybe I should wait until mid June before I plant replacement crowns.

When your tomato plants get frosted they will die (or at least start a quick downward spiral). It is good to get all of the usable fruit inside before then (the fruit might still be usable after a frost - it probably will not freeze, but I don't see too much reason to wait). The sun angle, shorter cooler days, and longer cold nights are all working against your tomato plants - there is a point at which they seem to stop and wait to die. If it is not going to get warmer your tomato season is probably over. You can pull the tomato plants with a bit of a root ball intact (knock the dirt off) and hang them in a shed, it is amazing how many of the fruits will ripen this way (I grow mostly paste types, different varieties could behave differently). There is a bit of a problem doing this even if you have the extra space, the ripened fruit is of decreasing quality and at some point it will be best to compost them. I hope this helps, best of luck!

thyme - definitely remove the seedheads from the big tulips and daffodils as soon as you see them start to form - actually, as soon as the tulips drop their petals and the daffodil flowers start to fade, I cut the flowerstalk down to the base. It reduces the 'mess' factor considerably by not having that dead-straight yellowing stalk poking up. It's easier to hide the basal leaves among other plants than it is to try to hide that stalk! But the small 'botanical' tulips and dwarf type daffodils should be allowed to set seed because most of those will spread nicely from seed without as much weakening of the 'mother' bulb - or at least the seedlings get to flowering size before the 'mother' bulb wears out. Judy - tulips are usually recommended to be planted about 6" deep - I aim for 8" in heavier soil and 10" or more in lighter soil (which I don't have!) In your climate, I'd think planting deep would increase their odds of returning for more years. Another important factor I think is to not water where they are too much during their dormant period. I don't think they like that. So make sure any companion perennials are not water-hogs that you need to provide a lot of supplemental water to in the summer. If I know I want to divide or move a clump, I wait until the foliage is ready to be removed and do it then (usually early July here). I that is not good timing (e.g. because I have to move/lift the companion perennial too and it's not a good time to disturb that plant...) I just mark where the bulbs are, either by leaving a bit of the old stems showing or put a few sticks in the ground or something like that... Then I can find them easily again when the time is right to move them. When we dig them, we start the hole back from the edge of where we've marked the bulb location. We know how deep them are, so it's fairly easy to dig them up without too much risk of damage.

What type of grass is it ? Some types do better than others after being on the pallet for too long.
