How to make a seedbed
Choose a sunny place in your garden to make a seedbed. Make sure that it is protected from wind.
Transplanting your seedlings from a seedbed into your trench garden
When to transplant
Transplant your seedlings when they are between 8 to 10 cm high. This is about six to eight weeks after planting. In summer it is best to transplant seedlings in the early evening when the sun is not so hot.
How to transplant
Distance between the seedlings
Plant your seedlings the correct distance apart otherwise they will not grow into strong, healthy plants.
A good way to measure the distance between seedlings is to use sticks that you have cut into different lengths. Use these sticks to mark out the distances that will be best for your plants before you transplant your seedlings.
Looking after the seedlings
For the first two weeks after transplanting, water the seedlings every day with a sprinkler or watering can. After two weeks the seedlings need to be watered two or three times a week. Do not let them dry out. Spread mulch around each plant to keep the soil wet for longer.
In summer, protect the seedlings from the sun and the wind. Place a small branch with leaves behind each seedling to give it shade. You can also use a net made of orange bags sewn together to serve as a shade-roof. Remove the net after seven to 10 days.
Crop rotation is when you grow different kinds of vegetables in each bed every season.
Why we rotate crops
There are two reasons to change the kinds of crops you plant in your beds each season:
1. To keep the soil healthy, and
2. To prevent disease
Crop rotation keeps the soil healthy
Don't plant the same kind of vegetables in the same bed every season. Each kind of vegetable crop needs a different amount of food from the soil. If the same kind of vegetable is planted every season, the soil can become very poor and then nothing will grow well. It is best to rotate your crops to keep your soil healthy.
Crop rotation prevents disease
Your vegetables may have a disease. If you plant the same kind of vegetables in the same place again, then they will also get sick. But a different kind of vegetable will not easily catch the disease. So crop rotation keeps your vegetables healthy.
Which crops to rotate?
There are three groups of vegetables: root vegetables; the bean family; and leaf and fruit vegetables. Each season you should grow from a different group in the same bed.
Root vegetables include carrots, turnips and beetroot. Root crops grow well even with a small amount of compost or old manure. This is why they are called light feeders.
The bean family includes peas, beans and lucerne. To grow well these vegetables need more food than root crops. This is why they are called medium feeders. But when these vegetables are fully grown there roots make the soil rich. They then give back to the soil more food than they have taken away.
Leaf and fruit vegetables
Leaf and fruit vegetables include tomatoes, potatoes, mealies, green peppers, spinach, cabbage and lettuce. They need a lot of compost and manure to grow well. They are heavy feeders.
Grow a different type of vegetable in every trench bed each season. The first season, grow root vegetables in one bed, the next season plant a vegetable from the bean family there, and the following season plant a leaf and fruit vegetable in the same bed. Then you can begin the cycle again. This will help to keep your vegetables healthy and free of disease.
