Vigorous & delicious Swiss chard

Vigorous, delicious, beautiful Swiss chard

I have often seen school gardens with vibrant, beautiful chard leaves left to wither. How sad! Chard belongs to the same family as Spinach (Amaranthaceae), does not have a chalky taste, and can often be used in spinach recipes. This recipe (an adaptation of one of the many variants of Boston Market Creamed Spinach) can be modified in many different ways, including as a creamy sauce over baked chicken or pork, sprinkled with buttered bread crumbs!

INGREDIENTS

  • Fresh chard leaves from garden, about 1 very large bowl (about 1.5 gal/6 litre capacity).  I don’t use stems but these can be set aside for a stir fry meal.
  • 6 tablespoons butter
  • 3 tablespoons flour
  • 1.5 – 2 cups chicken broth, milk or a mixture of both
  • 1/2 cup grated Asiago cheese (Parmesan, Romano, Gruyere also do fine)
  • 3 tablespoons olive oil (I use mild-tasting non-virgin)
  • 2-4 cloves garlic – minced
  • 1 medium onion – diced

There are 3 parts in preparing the meal:

  1. Harvest a very large bowl of chard leaves and steam till cooked but not overdone.  Overcooked chard or spinach is yech, so it’s best to undercook. You just want the leaves to soften. You should end up with at least 2 cups of chard.  Let drain and cool. Chop them up in large chunks so they’ll be easy to mix in with the sauce.
  2. Make a roux: Melt ~6 tablespoons of butter. Add ~3 tablespoons of flour. Mix well. Then add 1.5 – 2 cups of chicken broth or milk or a mixture of both. Mix well till smooth. Then add about 1/2 cup grated Asiago cheese (Parmesan, Romano, Gruyere also do fine). The consistency should not be too thick/heavy or too watery.
  3. In a separate pan, heat about 4 tablespoons of olive oil. When hot, add minced garlic and diced onions till golden or caramelized. Add the chard and saute about 3-5 minutes. Slowly add the roux and mix well. Taste before seasoning with any additional salt. Add spices like pepper and nutmeg to taste.

Bon appetit!

Voilà! A fabulous accompaniment or use it as a flatbread dip

This last section on companion planting (CP) sums up practical ways to cultivate a healthy garden with some “built-in” natural protection.

Intercropping vs. monoculture

By this time, you should be convinced that intercropping to create a diverse vegetable garden “habitat” is most effective to naturally protect your garden from pests, and can potentially enhance the yield of your favorite crops. Monoculture not only makes your valuable veggies more susceptible to pests in one season; sometimes, despite your efforts to work in rich, organic fertilizers, the same family of plants grown in the same area will fail in later seasons.

We learned this the hard way as we were initially concerned about having too many different veggies with too little yields.  As it turned out, yields started falling in later years as our broccoli became more susceptible to pests (BTW – brassica family, unlike tomato plants, generally like to be moved around).  So be daring, be bold, and experiment with different veggies – even those you think you’d never like!

Exploiting garden warfare

Your lovely spring garden or the woods near your home may look “serene”, but in truth, there’s constant warfare going on at a physical and chemical level.  So why not take advantage of it?

For instance, sunflowers may be great weed deterrents as they were found to be strongly allelopathic to weeds like wild mustard, jimsonweed and ragweed (Ref 1, p. 310).  Or what about selecting a “sacrificial plant or soldier” to protect the more valuable crops?  For instance, kale can be planted at borders of other more valuable cabbage family plants to draw pests away.  Or black nightshade can be used as a decoy plant to attract Colorado potato beetles away from your potato plants.  This may not be the best option for those of you with tiny gardens, but try to think of creative ways – even using containers which can easily be moved around – in deploying “soldiers” to protect your cash crops.

And while we’re on the subject of war, keep in mind that CP is not necessarily a mutually beneficial combination.  Some gardening experts believe that it is almost one-directional, though this can be difficult to ascertain.  For instance, you might consider that if carrots were planted next to peas or tomatoes (as our comparison of CP guides suggest), would yields from peas or tomatoes be greater at the expense of the carrots?

Using ornamentals to attract beneficials and help control pests

Many gardeners certainly deploy ornamentals like nasturtiums and marigolds to protect plants from pests like aphids, detrimental nematodes, white flies, and other pests.  But having herbs and flowering plants (esp. daisy and parsley families) also benefits the vegetable garden by attracting beneficial insects and birds that eat nasty bugs or pollinate plants.

We have had success growing tomatoes and beans with marigolds in containers, but have yet to attribute the yields/health of the plants to the marigolds. Some CP guides will suggest different varieties of marigolds for different pests (African, French and golden marigolds appear to be the best varieties).

Nasturtiums (whose flowers are a mildly peppery but delicious and attractive addition to your salad!) do have to be kept in check as they can take over an entire area, and are an incredible snail magnet on the West Coast.

Recording your own companion planting results

If you’re really intrigued by companion planting and want to put it to work for your garden, then record your observations.  Your best CP guide is your own gardening experience, though keeping in mind that results may not always be reproducible (see Part I).  A simple notebook or spreadsheet works perfectly well (of course, there’s Plangarden, too 🙂 )  Some variables to keep in mind are the yield and planting distance in the control vs. experiment plots.  For the die-hard garden geeks, we refer to Anna Carr’s excellent book (Ref. 1, pp. 332-355) that offers experimental techniques.

Good luck and may the companion forces be with you!
