The results are interesting and you don't need to use liquid nitrogen to check what happens. You can just put a banana in a home freezer and leave it there for at least 24 hours to be sure that it is completely frozen. Take it out and check what happens as it warms up.
In some parts of the country, spring is the best time to plant alfalfa. In others, it can be done successfully in late summer and early fall. It needs six to eight weeks of growing time before the first frost so it comes back with gusto in the spring. {C}.
A The sooner you get them in the ground, the better. Daffodils, hyacinths and smaller bulbs such as crocus, grape hyacinth and Siberian squill do best when you plant them by mid- to late October. Tulips tolerate late planting better, but it's still best to get them in as soon as possible. Be sure to water the bulbs after you plant them and then about once a week until the ground freezes, unless we have regular rain. Watering is important because bulbs need to start growing roots this fall in order to make it through winter. Once the soil freezes, mulch the bulbs with several inches of straw or leaves.
