Your soil test result shows a very high value for phosphorus, so you do not need and should not use a fertilizer containing phosphorus as more phosphorus will contribute to algae pollution in lakes and streams.  It also shows a low value for Potassium so you need to build it up in your soil.

Ask your supplier if they have a 6-0-24 (or 3-0-10 or 4-0-18) or something close to it.  If not check out some other nurseries or even a 'big box' with a garden center.  What you should try to find is a fertilizer: 1) with '0' Phosphorus and 2) an approximate ratio of 1:4 Nitrogen to Potassium.

hello,

I have 2 questions about planting lavender plants in the soil tested in this report.

Do you recommend that I use a compost/topsoil to build up my rows before covering with landscape fabric?  And I was told to use pea gravel.  Does the pea gravel get placed before you place plant in ground or after?

Thank you,

Patty

Yes, mix the compost in the top 2"-4" of soil before putting down the landscape fabric. You'll need to think about how to add more compost in future years w/ fabric down.  It's much less effective on top of the fabric.

 I'm not sure why there's a recommendation for pea gravel, except maybe as a path to walk on (thus put in top of the fabric).

This must be for bulk compost (mix).  If that's the only option, yes use it.  I'd ask for the % of compost in the mix to know what (% organic material) you're getting.  Shredded leaves, old sawdust , wood chips, straw are all acceptable materials in compost.  Here's an interesting article on topsoil:   Shocking Truths About Topsoil-MSU
