Companion Planting

Many plants have natural substances in their roots, flowers, leaves etc. that can alternately repel (anti-feedants) and/or attract insects depending on our needs. In some
situations they can also help to enhance the growth rate and flavour of other varieties. In nutshell, companion planting helps to bring a balanced eco-system to the garden, allowing nature to do its' job. Nature integrates a diversity of plants, insects, animals, and other organisms into every ecosystem so there is no waste. The death of one organism can create food for another, meaning symbiotic relationships all around. By using companion planting, we can discourage harmful pests without losing the beneficial allies. There are many varieties of herbs, flowers, etc. that can be used for companion plants. We should open to experiment and find what works for us. Some possibilities would be using certain plants as a border, backdrop or inter planting in flower or vegetable beds depending on our needs. We have to use plants that are native to our area so that the insects we want to attract already know what to look for! Plants with open cup shaped flowers are the most popular with beneficial insects.

Companion planting can combine beauty and purpose to give you an enjoyable, healthy environment. There are many ways we can find to incorporate these useful plants in our garden, orchard, flower beds etc.

Happy Gardening.

A Basic Idea-Soil pH

When any seed doesn't germinate with in reasonable time we blame the seed supplier, seed quality, climate etc. However we normally ignore whether the soil contains the required nutrients for the specific seed/plant.  To know the soil condition we have to measure soil pH level. The soil pH is a measure of the acidity or alkaline in soil. 

Plant roots absorb mineral nutrients such as Nitrogen and Iron when they are desolved in water. If the soil solution is too acid or alkaline some nutrients won't dissolve easily so they won't be available for uptake by roots. Soil pH is measured in a scale of 0 to 14. Where 0 being the most acidic and 14 is the most alkaline and 7 stands for neutral. To give you an example lemon juice can be of the range of 1 to 2 signifies very acidic where as soapy water can be of a pH of 11 to 12 which means it is very alkaline.



This pH is calculated on the logarithm scale so a difference between one point is equal to 10 times acidity. i.e, the pH of 6 is 10 times more acidic than pH 7 and 10 times less acidic than pH 5.


Soil condition varies place to place.  Your garden soil pH could be different from that of your friend's garden across town.  Therefore you should know soil pH of your garden before choosing plants.  Most garden plants grow well in slightly acid to neutral soil (pH 6-7). You can alter your soil condition after determining soil pH level from the soil testing labs. You can also test soil pH yourself with a home soil test kit or portable pH meter.  How to alter the pH level, please take expert opinion.

I hope this gives you basic idea about soil pH and its effect.

My Green House

You all know that Chennai's climate is too harsh to grow cool climate plants like carrot, cabbage, cauliflower etc.  Therefore, I made green shade at my terrace to try out cool climate plants.

I covered 850 sq.ft. of my terrace space with green shade net.  To cover all the sides, I needed 1400 sq.ft. of net (appx. 75% sunlight reduction net.  There were 50% & 90% shade nets also available).  One bundle of standard size (3 mt. X 50 mt.) net costed me Rs.2.16 per sq.ft.

To support the shade net, I erected bamboo structure first.  The cost of one medium size bamboo pole(around 16 feet long) was Rs.65. There were various sizes bamboo poles available ranging Rs.65-130.

It costed me around Rs.8000/- for covering 850 sq.ft. terrace space. The requried material were bamboo poles, shade net, ropes, stay wire, clamps, nails etc. Since I did the labour work myself, there was no labour cost added.

Hope I can now able to grow my dream vegetables.  Wait and see for my next update. Bye.

Health benefit of Gardening

I need little motivation to garden because it gives me so much pleasure and health benefits.
This time of year, I daydream about getting out in the garden, pulling weeds, pruning and planting. For me, a life-long gardener, there's nothing better than seeking solace, sun and good moments in my yard.
So, when I found these 10 reasons to garden, I had to share them because they cover every good reason to garden, or at least try it:
garden%20image.jpg
1. Gardening provides exercise that seems to be lacking in the Indians, especially
Chennaiities'  lifestyle. This comes from picking up pots, hoeing, raking, and chores related to tending the garden.
2. Gardening creates an opportunity by which vitamin D can be absorbed. It only takes 15 minutes out in the sun without sunscreen to absorb a daily dose of this vitamin.
3. Gardening provides more control over an individual's food supply especially for those who are concern with food security.
4. Gardening gives an individual a reason to be outside.
5. Gardening can create social situations where social interaction can occur. Long-term friendships can develop through a common love of gardening.
6. The process of gardening can improve one's mood and reduce depression. This is believed to happen due to exercise and vitamin D exposure.
7. Gardening is a great hobby that every individual regardless of skill or living environment can do.
8. Gardening is a great way of reducing one's carbon footprint by cutting back on food transportation cost and increasing foliage on the planet that can trap carbon or become a carbon sink.
9. Gardening is a great way to reduce stress. Getting back to nature and combining this with exercise can help reduce the stress at the end of the day.
10. Vegetable gardening can improve your whole family's dietary habits by providing the first fast food, which is fresh vegetables and fruits. It has been found that if kids are involved in the gardening process they are more likely to try new foods and eat more vegetables.

Bio-dynamic Agriculture

Do you know Bio-Dynamic Agriculture?


Bio-dynamics, derived from two Greek words, bios life and dynamos energy, refers to the agriculture science that recognizes basic principles at work in nature and applies this knowledge of life forces to bring about balance and healing in the soil.

Bio-dynamic methods produce a living soil with increased biological activity, in alignment with planetary cosmic rhythms, particularly those of the sun, moon and planets in the fixed constellations. Cosmic energies can work strongly through a living soil down into the plant. The coordinated working together of earthly and cosmic energies is what brings about healthy and nutritious plants. Bio-dynamics is a complete holistic outlook on agriculture.

To read more on this subject, please click the following link http://www.biodynamics.in/ of Bio-Dynamic Association of India (BDAI)

Also read the article on  Pest and Disease Control in Vegetable Cultivation by Organic & Bio-dynamic Farming Methods. For the beginners, this article is useful.

Seeds Sowing Chart-South/North India

Tamil Nadu Govt. Initiative

Dear Friends

There was a news item published in Times of India  dated 23-9-13, which is appended below:

The soaring price of vegetables has caused much heartburn, but people in the state may soon get their greens for free.

If the state government has its way, residents could soon be plucking fresh vegetables from their own rooftop gardens. As part of the plan to soften the blow of food inflation, the government will distribute do-it-yourself rooftop garden kits to residents.

Encouraged by a few individuals who have responded to rising prices by growing vegetables on their balconies, the government plans to introduce the scheme in Chennai and Coimbatore to begin with.

"The opportunity to beat rising prices by growing vegetables at home has led to people trying their luck with gardening. The government wants to chip in with support," a horticulture officer said. The horticulture department will roll out the scheme with support from Tamil Nadu Agriculture University.

People interested can apply online and the government will supply them with 20 UV stabilised 200 micron thickness polythene bags, 15kg of coir pith and manure, seeds for vegetables and greens, besides instruments, organic fertiliser and a 20sqm polythene sheet. It will make 20 bags available for each person at a subsidised price. Indian Overseas Bank offers loans to individuals for rooftop gardening.

Vegetables such as brinjals, tomatoes, chillies, cluster beans and amaranthus can be grown in the summer and spinach, radish, beetroot, snake gourd, bitter gourd, ribbed gourd and bush beans in the rainy and cooler months, said A Sadasakthi, professor, TNAU.

A brinjal plant yields an average of 5kg of the vegetable in six months, while two tomato plants yield up to 8kg. The government decided to use coir pith instead of red soil to minimise the weight of the plants.

Constraints of space may be a problem for many people in the city, but not for those who know how to use space effectively. "I found my tiny roof has lot of potential," says A M Malathi, who loves vegetables. The Medavakkam resident has been growing large quantities of pumpkin, bottle gourd, bitter gourd, snake gourd, ladies finger, cluster beans, brinjal, yam, and seasonal vegetables like beetroot and carrot.

She sometimes grows cauliflower, cabbage and capsicum. "I try dal once in a while too," she said.Vegetable gardens have the added advantage of making the house cooler. Exnora founder M B Nirmal said growing vegetables has other benefits as well. "It helps calm the mind and nurtures a love for nature," he said.
