when to start your herb garden

Who doesn't love those first warm, sunny days of spring?!

After a long, cold winter, we all have the urge to head outside and start puttering in the yard. It's the perfect time to start your new herb garden, right? Maybe, maybe not.

Before you go digging and planting, there are a few things to think about:

  • Is your garden still soggy from the spring thaw?

  • Has the soil warmed enough yet?

  • How's your soil's drainage?

When your soil's moisture, temperature and drainage are just right, then it's time to start your herbal tea garden!

testing your soil's moisture

Over-working soggy soil tends to break down the soil's structure. As it dries, the soil's natural air pockets compress, leaving hard clumps of dirt that air, nutrients and beneficial insects can't penetrate. In short: working too-wet soil creates a mess!

So, no matter how ready you are to start raking and weeding and digging and planting ... make sure your soil is ready, too!

how to test the moisture in your soil

Grab a handful of soil. Squeeze it. Then open your hand.

If your wad of soil is all gloppy and sticks together when you poke it with your finger, it's too wet to work with. Give your garden some time to dry out a bit. Then test again in a few days. 

When the soil forms a loose ball that crumbles apart easily, it's ready to be worked!

soil temperature

Remember, your plant's roots will live 4-6 inches (10-15 cm) below the surface. So it should be warm enough down there to keep the roots from catching a chill.

How warm is "warm enough"?
  At least 60
° F (16° C) is good. Warmer is better.

How to Measure Your Soil Temperature

I like to use a digital thermometer, as you saw in the photo above. But there's no need to go that tech-y if you don't want to.

This simple thermometer is inexpensive and will do the trick. Just stick the probe deep into the soil, and give it about 10 seconds to accurately register the temperature.
 

soil drainage

Herbs prefer soil that drains well.  

Too-fast drainage allows water and nutrients to slip right through a plant's roots before they can soak in what they need. Not good. 

Too-slow drainage
leaves the plant sitting in water, and rot can set in. Also not good.

How to Test Soil Drainage

Grab a shovel, a timing device, and your watering hose. Then head out to your garden.

  • Dig a hole about a foot deep and a foot wide.

  • Fill the hole with water.

  • Now, time how long it takes all the water to drain from the hole.

10 to 15 minutes? That's what we gardeners - and our herbs - hope for!

* Helpful Hint:  Does your soil drain too quickly or too slowly? Not to worry! In most cases, soil problems are fix-able.

how to Plant your herbs

First things first. Should you grow your herbs from seeds or start with nursery-grown "starter" plants?

seeds vs. starter plants

With only one exception (German chamomile), I recommend starting with nursery-grown plants instead of seeds.

German chamomile seeds germinate quickly and grow prolifically. One packet of seeds will give you more chamomile than you can imagine.

Other herbs are more of a challenge to start from seed because their germination rate is poor (I'm looking at you, stevia!). Or the seeds might not grow "true" to flavor (I'm looking at you, too, mints!). 

All things considered, starter plants are the way to go. They're easy to find in local garden centers and from reputable nurseries online.  Perfect for us (almost) instant gratification types!

transplant "shock"

Like we humans, it takes herbs a little time to adjust to new surroundings. To avoid the risk of transplant shock, give your herbs a few days to acclimate to the environment. 

Leave them in their nursery pot, in a sheltered area, out of direct sunlight and wind. If the leaves look droopy, feel the soil. Is it dry? Spritz it with a little water.

Otherwise, just leave the plant alone. In a couple days, it'll be all perked up and ready to settle into its new home.

planting depth

When transplanting nursery-grown herbs, take care not to plant them too deeply. They should sit at the same soil level as they were in their nursery pot.  

When starting from seeds, remember that some herb seeds need sunlight for germination. Simply scatter the seeds over the surface of your soil, then gently tamp them down  to assure there's good seed/soil contact.

watering in

As soon as your herb plants and seeds are in the ground, be sure to water them in.

For seeded areas, be extra-gentle with your hose or watering can. If you blast a full stream of water on the newly seeded area, you'll dislodge the seeds. So just give them a light sprinkle and call it good.

Nursery-started plants can be watered a little more aggressively. But you still want to avoid beating your little plants up or drowning them. Use a gentle spray with just enough water to settle the soil around the plant.   

After that, water as needed to keep the soil uniformly damp - usually every day or two - until your herbs are well established and growing strong in your garden.

caring for your herb Garden

Congrats! Your plants and seeds are in the ground. You're officially a DIY Herbal Tea gardener!

Now, let's move on to the basics of maintaining your herb garden ...

fertilizing your herbs 

One of the biggest mistakes many first-time herbal tea gardeners make is over-fertilizing their herbs.

When herbs are over-fed, they grow big, beautiful, bland-tasting leaves. Bland ingredients are definitely not what you want for your tea!

If your soil is on the "poor" side, work a bit of organic compost into your garden soil before you plant.

Beyond that, a weekly feeding of all-natural plant food (this is what I use), mixed at half strength, should be enough to help your herbs produce lots of wonderfully flavored tea.
 

Reminder ...

Rugosa roses (the variety that produces the best rose hips for tea) and lavender are two herbs that thrive in poor soil conditions.

Be especially careful not to improve their soil too much or fertilize them too often!


weeding your garden

Sorry, there's no way around it. Even container plants can pick up a stray weed every now and then. So weeding is a must!

Your herbs shouldn't have to compete with weeds for sunlight, water, nutrition and air circulation. Plus, a nicely tended garden space looks so pretty. So keep it tidy!

mulch or no mulch?

I'll admit it. I'm a lazy weeder. So mulch is my friend!

A 2-3 inch (5-7.5 cm) layer of mulch keeps weeds at bay, maintains an even soil temperature, and holds moisture in the soil.

Best mulch choices are:

  • well-aged compost or cow manure

  • natural pine bark (not the artificially colored stuff!)

  • clean straw 

The biggest problem with other mulches is that you have no idea what kind of yucky stuff is in them. 

Recycled wood or rubber-based mulches might contain toxic chemicals from their "prior life".  Plus, rubber stinks to high heaven in the hot sun. Blechh!

Landscape fabrics do a good job of reducing the need to weed. But some fabrics do contain chemicals. And, if the fabric isn't permeable enough, it prevents water and nutrients from getting through to your plants. 

So my mulching caution is: Be absolutely certain that any mulch you use is permeable, organic and 100% chemical-free. You don't want potentially toxic stuff anywhere near your tea ingredients!
 

Tip:  It's best to keep mulch at least 4 inches (10 cm) away from the base of your herbs. Putting it right up against your plants invites stem rot and bugs. 
 


how often to water

As you get to know each of your herbs personally, you'll begin to recognize their "Gimme a drink!" and "Enough, already!" signals.

Until then, here's a quick guide to their moisture preferences:

Moisture-Loving Herbs

These herbs like uniformly moist soil, but not soggy:

  • Mints
  • Lemon Balm
  • Anise Hyssop
  • Lemongrass
  • Stevia
  • Bee Balm
  • Lemon Verbena

Drought-Tolerant Herbs

These herbs can tolerate a bit less watering:

  • Lavender
  • Rugosa Roses/Hips
  • Chamomile

How can you tell when your plants need water? Poke your finger into the soil. If it feels dry 2 inches (5 cm) below the surface, it's time to give your plants a drink.

The best time to water your herbs is in the morning, before the sun starts beating down on your garden.  

Think of it like "breakfast" for your plants. Get them off to a good start with enough nice, cool moisture to sustain them through the heat of the day.
 

How Much Water?

A plant's roots naturally grow toward their moisture supply.   

Daily, shallow watering results in weak, shallow roots. So water less often, giving your herbs a slow, thorough soaking each time. That'll help them grow a strong, deep root system.
