Why Practise Green Gardening?

I love gardening - I especially enjoy the way those tiny little seeds grow into big, leafy green plants. Unfortunately, insects and pests also love my new little plants and it seems to be a battle that is fought every year.

It really irked me the first year that I started my veggie garden to find my little babies decimated by insects. I wanted to save them and prevent that happening again but without using poison.

I looked into green gardening and saved myself a bucket of cash - I can also rest assured that I didn't poison any birdies or the water supply.

I have even gone so far as to incorporate the petals into a mix with soapy water - very diluted and Khaki Bos (A South African weed) to use as a more natural insect spray. (This involved surreptitious little stops on the side of the road, making sure no one was in sight - it is illegal to pick flowers on the side of the road in South Africa - and quickly tossing them into the boot - you do not want Khaki Bos in your garden - it is a pernicious weed.) The soap helps the spray adhere to the plants. There are a lot of herbs that make effective pesticides.

I found that the natural methods are extremely effective.

I have especially found that companion planting is a great way to combat pests and diseases, costs less and is safe for the environment.

A lot of herbs can be added to the garden for companion planting - this boosts your veggies and gives you lovely herbs for flavoring them with when cooking. It is a win-win situation.

Some Tips From David Thorne About Growing them From Seed

Growing Marigold Tagetes

These are very easy to grow - you can choose to grow them from seed sown directly in the ground or by planting seedlings. If you are growing them from seeds, you just need to make sure that the ground remains moist. You do need to make sure that the last frosts are over as these are frost-tender.

I personally prefer planting seedlings as then I can see exactly where they are being planted. The young seedlings can also easily be confused for weeds, especially in a veggie garden so, if you are growing them from seed, plant into seed trays first and then plant out.

Many people ask me, "Will my Marigold Tagetes self-seed?" The good news is that you will only need to buy plants once, these plants self-seed well - When the flowers have started withering, I collect the blooms and save in an envelope. I leave a few on the plants and always have little babies coming up. One bloom produces lots of seeds so you will have plenty to keep for the next year.

These are very hardy plants and will grow just about anywhere. They do better in soil that drains well with a good proportion of loam, though. Once they are established, you can pretty much forget about them - no need to worry about fertilizers, etc. I do give them a sprinkling of worm tea once in a while, though.

They do tolerate very high temperatures but I do water mine when the weather is very hot - I don't let them become parched.

They are annuals and will usually die down completely in winter. (Not to worry, though, when Spring comes around, they will start up again.)

I have found, however, that I often am still getting new plants growing well into Autumn. Part of the fun of using these plants as a natural insect repellent is that they come up all over the place.

I also like the fact that the leaves are very distinctive - I never confuse these babies with my veg seedlings. (In my first veggie garden, weeds were a problem because I never knew which of the seedlings where veg seeds that I'd planted and which were actually weeds that came up on their own.

Marigolds to Beat Insects

I planted Marigold Tagetes on the outside of the beds and in random spaces around in the vegetable bed as well.

They are effective in a couple of different ways.

First off, the roots and stems emit a chemical that insects find unpleasant and so this keeps them away.

The petals have this same chemical so I would often pluck off a few petals and scatter them around the garden. For this reason, I had no problem leaving any petals or leaves that fell to the ground in place.

Snails will leave them alone completely because of their bitter taste but, unfortunately, the same cannot be said for rats. My first crop in the new garden was decimated overnight - if you are battling with rats, make sure to cover the plants at least overnight - they will still be effective because the roots exude the toxins that the insects dislike so much.

Where are They From Originally?

A Splash of Colour in Any Garden

There are a lot of variations when it comes to Marigolds.

You can choose the basic single bloom or the showier double bloom.

Colors are also varied - mostly reds, oranges, and yellows or combinations of these - these are really sunny plants in the garden. The leaves are always green but the petals can be a solid color or brilliant combinations of different colors.

They make great additions to window boxes and to hanging baskets as well. Being hardy, they can be placed in soils that other plants battle to establish themselves in. They are bold, brash and showy - showing them off in the garden is the best use of their talents.

They also make a nice display in the home if placed in a small vase. Keep them on their own in the vase, though - they are not good to put in with other flowers - they will make the other flowers wilt quickly.

You can press them if you want to but they are quite bulky so be prepared to wait a bit longer for them to dry properly. They are not good as air-dried flowers - they will not keep their color, will quickly lose their petals and have no value in potpourri at all.

Safety Info

Marigold Tagetes should NEVER be taken internally. They are highly toxic if ingested.Should you, or a loved one, swallow some get to an emergency room as quickly as possible.

For health benefits in humans, you need to make sure that you are using Calendula proper (Also often called Marigolds or English Marigolds.)

Calendulas have a range of different health benefits and can be safely consumed. They are also a very useful plant to add to your garden.

If you are unsure, for any reason, which plant you have, rather err on the side of caution and do not use it at all.

Here's a Great Video from David Thorne about Growing and Caring for African Marigolds

As Cut Flowers

These flowers do make very good cut flowers. A lot of Hindu people in South Africa use these flowers as offerings/ decorations on household shrines.

They last very well in the vase but do have quite a strong smell. Keep them in a well-ventilated room and this won't pose a serious problem.

Make sure to remove all the leaves below water level or the water will go mucky very quickly.

Very nice and informative hub! I love Marigold for its bright and vibrant colours and it is very popular in India for decoration purposes, Garlands etc. But I learnt a lot from your hub today about benefits of Marigolds.

Thanks for sharing your knowledge! Voted up!

Hi Dolores, although I am very keen on veggies, I love flowers as well so I love the lines of marigolds. I'm interested that they used dried marigolds strung up - I've never had a lot of luck drying them out - maybe I've been doing it wrong.

At my house, I am the flower gardener and my husband grows vegetables. He always plants those pretty little marigolds around the edges as an insect repellant. I once visited a historic home where they had strings of dried marigolds hung in the kitchen to ward off insects. It looked so lovely! (Voted up and shared)

Dear Naomi, that said, they are nice little plant - if you steer clear of eating them you'll be fine.

Very informative article! Picks are quite nice! I'm afraid I would not try to distinguish the edible from the not! Too dangerous. Well done.

Dear Thelma

They do well in Durban and that's sub-tropical so I'm sure they'll do well - they are very easy to grow and will grow just about anywhere. They don't like the cold though.

These are beautiful photos. I hope Marigolds are good for tropical weather as well as I´m planning to plant these in my garden. Thanks for sharing this very useful and informative hub. Have a nice week!

Certainly did not know you could eat them. They work great to deter bugs. Thanks for sharing your information and the beautiful pics.

Hi Rajan,

Marigold Tagetes is the one to use for repelling pests - the Calendula, (Or "proper" Marigold) doesn't have the same pest repellent properties.

If Marigold Tagetes isn't available, garlic is also quite good at repelling pests as is Thyme.

Thanks for the visit.

rajan jolly 3 years ago from From Mumbai, presently in Jalandhar,INDIA.

I was wondering if Marigold Tagetes is the only species that has the ability to repel insects or do all species of marigold have this property?
