Why Soil Matters to Plant Growth

How to

For a visual reminder of why soil matters so much to the health and vigor of plants, see the two photos below. These are identical sunflower plants. I planted them on the same day late in the spring. The plants are located less than 20 feet apart in identical full-sun exposure. Why are some of the sunflowers only waist-high, while others are over my head? One word: Soil.

These sunflowers got the poor soil and they are struggling.

The short sunflowers are planted in the little meadow between our yard and the path around the city storm-water drainage ponds. I’ve never improved that soil — it’s just what the city and the builder left behind after building our house. It is, as soil scientists might say, lean.

What a difference good soil makes! These guys are twice the size of their neighbors.

The tall sunflowers were planted on the edge of my vegetable garden. A few years ago, a load of landscaper’s black dirt was dumped there for use in another garden. I didn’t need all the dirt I ordered, so I left it there. This spring, I installed a lasagna garden for planting tomatoes, a rich mix of dirt and compost. The soil near that bed is very close to garden perfection: well-drained, humus-filled soil.

Not every plant thrives in rich soil — nasturtiums, sedum, and many herbs prefer a slightly lean soil — however, if you’re plants aren’t as tall or robust as you would like, consider giving your dirt a boost—soil matters.

I’ve loved this container in the front of our ho I’ve loved this container in the front of our house, but things are looking faded, so it’s time for a refresh. Out went the Persimmon supertunias (love them, but they have done their duty) and a new cuphea I’m testing (great plant.) In go fall celosia in bright yellow and bronze orange garden mum, both from @shopbachmans. I kept the Queen Tut papyrus for its spikey texture. We’re ready for fall!

Meet shaggy soldier, a weed that I have gotten to Meet shaggy soldier, a weed that I have gotten to know quite a bit this summer. It spreads like crazy, seeds abundantly and is all over my community garden. Sone sources say it is an edible herb but I’m just pulling for now. Next year, I’ll smother it out with newspaper, cardboard and/or mulch. What weed is your nemesis this year? #weedsinmygarden #galinsoga #shaggysoldier #mngarden #communitygarden #weedy #herborweed

Ground cherries look like tomatillos but taste lik Ground cherries look like tomatillos but taste like tropical fruit.
They are an acquired taste but I love them, especially in a spicy jam. 

For this recipe, I mixed

2.5 cups of cleaned ground cherries, 
half a cup of water,
1 cup sugar
a few stray strawberries from the fridge,
 juice of a small lemon, 
a 1-inch piece of ginger
1 tsp each of cinnamon and nutmeg

 Boil away until it is thick. Store in the fridge and use as you would any jam.
