Planning your herb garden

Herbs require very little care compared to many plants. How many times have you had to spray your roses or trim your orchids? Herbs, by comparison, do well in poor soil, require little fertilizer and only modest watering. If they get lots of sun and a bit of water, they usually do well all on their own.

But you'll still want to do some planning before just throwing down seeds and walking away.
For one thing, since herbs thrive well in relatively poor conditions, they can become overgrown. Lavender will spread, Yarrow can take over large areas. Even Chives can get bushy and packed. Make sure you start with adequate space in your pot or garden for the number of plants you have in mind.

Most will get along fine if they have about a foot of space between major sections. Chives, for example, look great and grow well in a bunch. But the roots still need a certain amount of nutrient and water. Other plants nearby compete for those.

Also, in order for adequate sunlight to reach the plants, they'll need a certain amount of area, alongside them and within them. Planting too many within a confined space will make that difficult. Thinning may be required later as more plants than you expected develop.

Soil preparation is minimal for herbs, but minimal doesn't mean non-existent. A good compost or mix of sandy loam and clay will support a wide range of herbs. You'll want to make sure it has adequate drainage. Many herbs are originally natives of the Mediterranean, so they'll do well in rocky, relatively dry soil. They evolved in conditions of good drainage. But all herbs need some water. It should be moist, but not wet.

Lavender and Sage, just to pick two, can get by in most areas with no manual watering at all. The occasional rainfall is enough. Peppermint will want a little more, which can easily be supplied by an automatic drip system.

You'll want to minimize weeds, possibly by laying down some landscape fabric. You'll want to avoid having to dig weeds up later or deal with the problem by using herbicides. That can kill the herbs along with the weeds (many are biologically similar). It also means you're spraying chemicals onto plants that you may later plan to eat.

Herbs resist insects well, but you may want to help by being prepared to sacrifice some for the sake of preserving others. Dill will make for a good 'trap crop', this is one which attracts pests away from other plants such as tomatoes. If your goal is growing Dill, a small amount of insecticide will take care of the problem, but use the minimum possible.

Plan when you want to plant by judging which herbs will do well by beginning at various times of year. Some can be sown anytime, others should be planted at intervals of four weeks, still others should begin as early as possible after the snows melt.

Plan ahead and you'll find your herb garden easy to care for and thriving with very little effort.
