alyssum ; gaura ; and caryopteris

In my Hummingbird and Butterfly garden I have 6 Alyssum ( Basket of Gold ), 3 GAURA ( Whirling Butterflies ), and 1 CARYOPTERIS ( LongwoodBlue )that has not shown any sign of growth yet. I know last Summer 3 of my Alyssum went rotten, I don't know if it was from the march that I put on the garden or if it was do to the amount of rain we got when I was on Vacation in July, we got like 3 inches of rain at once they told me when I got home.

The GAURA are not showing any signs of life ether and I would love to have them come back each year. I do not know any reason why they did not come back. If you could help me out here so I could get a very good growth on them and perhaps pick one that is more suited for my area it would be helpful?

An the CARYOPTERIS it could have be me, I cut it down to about 2 inches above the ground in January. Is this a hard plant also to grow? Or did I do something wrong?

If you could HELP ME OUT here and show me where I may of made a mistake please do so.

My soil is Clayish loam and has allot of Organic matter in it. The Soil Test shows around a 7 so I am in the Middle a little high but they told me it was OK.

TWO years ago I put about 8 loads of Horse Manure on the garden to brake up the clay soil which I did and now it is really louse and fertile.

A light mulching, less than 2 inches, should be okay. If your clay loam soil
is only a foot deep and under that in heavy clay then that heavy rain water may not have been able to drain away from the roots fast enough. The plants you listed do not like wet feet. Check it out.

I agree the problem is not soil fertility, but soil drainage. The plants you listed will do well in soil with very low fertility as long as they have good drainage. I recommend you do a percolation test to see just how well your soil drains. Dig a hole 18 inches deep and wide. Fill it with water and let it drain completely. Fill it again and this time keep track of how long it takes to empty. If it takes longer than 5 hours, I would suggest you look into raised beds for your planting. Al
