Pizzas & pumpkins + all about garden soil

RSVP here for the rescheduled Fall Pizza Potluck and Pumpkin Party- 
Saturday, November 4th, noon to 3pm 
We grew 75 pounds of sugar pie pumpkins to share with our garden community. If there are more people than pumpkins, we'll have a raffle, but I hope that by giving out one per family we should have enough. The wood fired pizza oven will be hot and supplies for make-your-own pizzas available + delicious food that everyone brings (that's you)! RSVP by November 1-thanks!!

Garden resource Day- Saturday November 4th, 10am-noon
While I'm at the Ft. Scott garden getting ready to host the pizza party, the truck will be there with compost. Please come by if you want some to add to your garden. If you haven't been there before, the garden is at the end of Wisser Court- enter by 1330 Kobbe and take the 2nd road on the left (it's gravel and goes past a few garages). Vehicular entry will be closed at noon for the pizza party.

Looking ahead to December: Saturday December 9th, 10am- noon winter wreath making at the Native Plant Nursery. More details in future posts.

Hey everyone! This is Taylor (Jean’s gardening intern) kicking off a series of informational gardening posts with an exciting look into soil health. Healthy soil= healthy plants: providing your plants with soil rich in organic matter helps them to grow faster, resist pests and diseases, and yield a larger crop.

The soil in your raised beds should have a healthy combination of sand, silt, and clay (a “loam” soil) as your bed has been prepared specifically with a loam and compost mixture. A good way to check your soil is to do a simple jar test. I’ve included an image that gives you instructions on how to conduct a jar test below. I just pulled the image off the internet but it actually gives really great instructions!
Once you’ve identified what your soil is composed of, you can start assessing what amendments or organic fertilizers (if any) are necessary. Compost is a great amendment to consistently add to your raised bed because it actively builds up soil health while slowly releasing many nutrients to your plants over time. Mixing 4-8 inches of compost into your raised bed before planting would be a great idea if you think that your soil is nutrient-depleted. Also a 1-3 inch layer of compost would be good to add to your raised bed a few times a year as a top-dressing. HOWEVER it is important to remember that compost is an amendment to build up soil health and NOT a fertilizer.
Your plants need a healthy balance of NPK (as well as other minerals) in order to thrive and yield a bountiful harvest! Only fertilizers can provide your plants with fast acting doses of NPK. NPK=nitrogen, phosphorus, and potassium.  
*Nitrogen helps with leaf growth, phosphorus with root growth, and potassium with flower/fruit growth.*
It’s important to remember that too much of one element of NPK and not enough of the others could be a serious limiting factor for your plants. Too much nitrogen (without enough phosphorus and potassium) could cause your plant to grow too many leaves while limiting flower/fruit growth. This could pose a problem for fruiting crops (such as tomato or strawberry plants), but might actually be helpful when growing leaf vegetables like lettuce, chard, and spinach. It’s important to cater to your plants needs especially if you want to get the most from your harvest. Adding organic fertilizers that are rich in nitrogen, phosphorus, or potassium is the best way to immediately provide your plants with the nutrients they are missing. I’ll most likely be writing a post about organic fertilizers in a few weeks so stay tuned!
That’s all I’ve got for soil health! Email me if you have any specific questions- tjais@presidiotrust.org
