Growing Clematis From Seed

Online information about growing clematis from seed is limited. As a result, I decided to investigate clematis seed germination in more detail by running 120 test cases on a number of different types of clematis. This report summarizes known information and presents new information found as a result of this work.

Eggshells – Decomposition Study

The advice to add egg shells to the garden or compost pile is very common. In my last post I looked at some evidence that suggested eggshells do not break down in a compost pile or in soil – at least not very quickly. The one exception where eggshells do break down is very finely ground eggshells added to acidic soil .

How quickly do eggshells break down in soil? Is it 6 months or 5 years? Maybe it’s 100 years? No one seems to know. In this post I will describe a 6 year study that has been started to find out if eggshells decompose in that period of time.

Pruning trees and shrubs in late summer is NOT recommended because such pruning causes new soft growth that can’t harden off before winter. You will find this advice everywhere, but is it correct?

Getting Rid of Slugs with Coffee Grounds

In the two previous posts I looked at ways to use Coffee Grounds in the Garden and the effect of coffee grounds on ants. There was one outstanding question that did not get resolved. Do coffee grounds deter slugs from eating your plants? Since I could not find any scientific work on this topic I decided to run some tests myself.
