GARDENING GURU: Plant a garden of repeat performers

Published on May 26, 2014

Much is made about saving money these days. I don’t need to name the retailers who love to spout about how buying cheap enhances your life. Me? I was brought up to believe that you get what you pay for. Experience has taught me that this generally is true, though not always.

As you venture out into your garden this weekend you may contemplate where you will plant some edibles like veggies, herbs, fruiting bushes and the like. Well, if seeking good value courses through your veins, I have some news for you. The best value for your gardening dollar — and effort — is not to be found in a sweat shop off shore. It is as near as your farmers' market or garden retailer and the chances of a permanent food garden start where nursery grown plants are sold by reputable retailers in your neighbourhood.

Here are some plants that produce a great crop year in, year out and they are pretty low maintenance, too. So you can have your asparagus and eat it too. And still have to time to shop at the retailer of your choice.



I was not sure whether to list my best value edibles alphabetically or in order of preference. Either way, asparagus tops the list. It is a peculiar plant, with roots in eastern European countries and western Asia. The oldest surviving cookbook is all about asparagus, written by Apicius in the third century. So you know we've been eating the stuff for some time.

To grow asparagus, I encourage you to plant the two-year-old ‘roots’ that are available at garden retailers and mail order garden catalogues everywhere. These roots will save you two years of waiting for seeds to grow to the same stage.

Dig a trench 30–centimetres deep and equally wide and turn in generous quantities of finished compost in the bottom of the trench, about 10 centimetres deep. You will feel like you are digging a grave at this point but I assure you that your asparagus crop is a celebration of life as each spear contains more vitamins and minerals than I have space to list here. It would be easier to tell you what asparagus does not contain, of a healthy nature. Note that female plants produce mildly poisonous berries.

Plant the roots in the bottom of the trench. As they grow, gradually fill in the trench with triple mix or quality planting soil. In about four weeks, your green shoots will be reaching for the sky. Now wait for three years for your first crop of fresh asparagus.

Your patience will pay off as your asparagus patch will, in all likelihood, out live your tenure at your current place of residence. I have seen patches of the stuff still producing after 30 years. Diligent weed control is the long-range answer to success. That, and an annual layer of compost over the roots, about four centimetres thick.



The expressions about rhubarb often suggest that the word is used as a substitute for the word nonsense. I can tell you that having it in your garden is anything but. It is so easy to grow that you will find yourself wondering why you didn’t plant it years ago.

It requires an organic, rich soil, loves the sun and welcomes spring before most any other edible in the garden. I have been pulling my rhubarb for about three weeks now (you pull it, don’t cut it.) No need to be jealous, just make some room for a root or two in your garden and you will be pulling it too, in about three years.

Take only the long, young stalks and cut off the leaves, which are poisonous. Remove flower stalks as they are produced to maximize leaf/stem production. As your plants mature, they will produce a crop for up to 10 weeks, but not until they have been established for five or more years. Don’t delay. Time is ticking by. Once planted, rhubarb goes on forever.



They love the sun, they are easy to grow but not always easy to keep the birds out of as they ripen. A layer of cheese cloth draped over them at harvest time usually prevents this problem.

Buy one year old plants this time of year and line them out in a row about 30-centimetres apart in sandy/loam soil. Triple mix works like magic. Keep weed free and let the runners establish themselves as they are produced. They will root where they grow. For the first two seasons, remove the fruit to encourage lots of ‘top’ growth and in the third season get to work picking, cleaning and eating the sweetest strawberries that you have ever tasted. They always taste sweeter when you grow them yourself.

I mulch my strawberries with a thick (20-centimetre) layer of clean straw each fall (thus the name) and remove it mid-May to encourage the sun to work its magic.



Ever-bearing or July-bearing? You choose. I think both have their advantages.

July-bearing raspberries produce an abundant, sweet tasting crop that is finished in two to three weeks. This is perfect for preserving or freezing. Ever-bearing raspberries are actually ‘late season’ bearing, producing most abundantly mid-August through September.

I remember when my mother-in-law picked a crop of ever-bearers in a snowstorm in November and made a pie with them the same day. You get the idea. The only downside to the ‘ever-bearing’ varieties is that you get a smattering of a ripening crop over a period of several weeks and they are not as sweet tasting as the July-bearing.

Nothing is easier to grow, however. And they produce a crop for years after being planted. Prune raspberries annually to maximize the fruiting potential and to avoid having them take over your property. I prune mine down very hard in late summer, to about 20-centimetres high (for July-bearing) and the ever-bearing varieties, I prune down to 50-centimetres high in late fall or early spring.


Fruit trees

Plant apples, peaches, pears, plums. Why, when we are looking for a good tree for the yard, do we so often overlook the fruiting species? They do require some insect and disease control. Best that I write a future column on the selection, planting, care, feeding and harvest of fruit bearing trees. Meantime, put them on your radar.


Edible flowers

Not all of them are perennial and return each year but the chances are you are growing some of them and looking at them right now. Nasturtiums, roses, gladiolas, pansies, violas, to name a few. For a complete list, go to my website at and search ‘edible flowers’.
