What is the best way to prepare my raised beds for planting each year?   I’m on year 15.

Hi Sue,

If you've been growing in the beds for 15 years and likely amending each year, you might not need to do anything. Are the beds productive? Any issues?

You don't want to overamend, and if you've been adding organic materials for years, you probably have a high percentage of organic matter for proper plant growth.

You can always add grass clippings (if you're able) as a thin layer of mulch. They will also add some nitrogen and break down, benefitting your soil.

Not as productive as I’d like or maybe they used to be. I didn’t know I could stop amending!  I add a bag of organic plant based compost each year to each bed. They’re 4x8’.  This year I am wanting to mulch to keep the moisture in. We sprinkle most of the beds as it became to difficult to use the little hoses to each plant as I began to rotate the veggies. Is grass mulch still ok for that type of watering?  Should I water every other day in the heat?  For how long?  Thanks!!!

Hi Sue,

You may consider getting a soil test, understanding that the CSU Soils lab is running on a 2-3 week delay: http://www.soiltestinglab.colostate.edu

A routine test is $35 and covers all the basics. If you have done one in awhile (or ever!) it would be worth the investment.

Mulch is always good...and using something that breaks down quickly is better than a wood-based mulch, which becomes cumbersome to move around each year. 

By sprinkling, do you mean you're watering with a hose and wand? Or do you have drip irrigation? Overhead watering can be more inconsistent than drip, so that could lead to some of your productivity issues.

What are you doing for fertilizer?
