A very useful and satisfying practice, particularly for growing vegetables where there is little space, is container gardening.
A patio, window sill, or rooftop space is ideal to make a bright show of flowers and supply the kitchen with herbs and vegetables.
Container vegetable gardening also allows greater control over pests and poor soil conditions . It is also less labor-intensive than growing in raised beds and in-ground plots.
How to Start a Container Garden
Below are some tips to get started with your potted garden.
The right size container for the plant matters. Choose one that is at least 12 inches deep and 10 inches wide.
Compact plants require smaller containers. However, large plants need room for the roots to spread and the plants to thrive.
In a hot climate or long sunny spells, bigger containers with good drainage will help keep the plants from drying out.
Barrels, troughs, wooden boxes, crates, or attractive old urns could be used. However, if placing them on a roof or overhanging balcony, weight restrictions may be a consideration and lighter materials necessary.
Half-barrels are very useful and attractive or plastic containers. Plastic pots for growing vegetables are not as pleasing. However, they retain moisture well and are very durable while wood can rot and clay can shatter in frosty weather.
When growing in containers, you can use terra cotta pots or glazed ceramic pots. However, terracotta pots can be good or bad for plants. The porous nature of the material allows water and air to pass through the container . This causes the soil to dry out quickly.
On the other hand, terra-cotta prevents overwatering. This, in turn, prevents root rot and soil disease.
A wooden planter box or DIY containers such as a toy bin or laundry basket can work too.
Container planting needs particular care in watering. The plant roots can dry out quickly. Therefore, once or twice a day watering is wise for outdoor containers. Moreover, some plants like tomatoes are particularly thirsty.
Another good idea is to double up the containers. Put one inside the other and fill the space with sphagnum moss which can be watered as well. Self-watering containers are also well worth considering.
Plants can suffer from overwatering too. Therefore, the right drainage and potting soil are as important as the container material. Pots should have big enough holes in the bottom to release excess water.
Using garden soil is a real no-no for containers unless it is amended. Garden soil will likely clog and retain too much moisture. It may also import weed seeds, diseases, and pests.
Molasses and liquid kelp are other fertilizer options for your potted vegetable garden.
This is a prime consideration in pots and containers to prevent root rot, yellowing, and wilting due to excess water.
Making one middle hole and several smaller holes spaced over the bottom of containers can prevent soil from clogging up around roots.
To avoid the holes being blocked, place some pebbles at the bottom. You can also cover the drainage holes with material that allows water to drain freely.
Planting Seeds or Seedlings
When growing vegetables in pots, you can start from seeds or buy seedlings. They both have their advantages and disadvantages.
Planting seeds is cheaper than buying seedlings, especially if you save your seeds.
However, growing from seeds is not for everyone. You cannot let them dry out. You will also have to ensure that they get the right amount of light and good air circulation.
To avoid all this, purchase seedlings from your local garden center.
Best Vegetables for Container Gardening
With care, most vegetables can be grown successfully in pots. These are some of the best veggies for containers:
- Tomatoes – Any variety of tomatoes can be grown in containers. However, large pots are essential for root development. They may also need a support system.
- Potatoes – These also need large pots, plenty of sunshine, and good drainage to thrive. Pots should be at least 15 inches deep.
- Beans – There are different varieties but those grown on poles or up trellises are attractive as well as good growers. Bush varieties do not need support. Wooden boxes, Terra-cotta pots, and barrels are ideal containers.
- Spinach – One of the best and easiest to grow in pots. It thrives in partial or full sun and almost any spot but requires nutrient-rich soil.
- Peas – Another easy crop to grow in pots with very little attention needed. Water frequently and use tall supports.
- Carrots – Being root crops, carrots require plenty of space for root development. A large wooden trough might suit, well-watered in light, fluffed-up soil to avoid the soil compacting.
- Kale – This fast-growing, very productive plant needs well-draining and fertile soil to provide a highly nutritious green vegetable.
- Onions – Plant these at least five inches deep. Onions, especially green onions, do well in planter boxes as long as you space them properly.
A wooden box or large window box can provide a variety of salad vegetables for the kitchen. These include lettuce, arugula, peppers, cucumbers, radishes, herbs, and beets.
Swiss chard, asparagus, pumpkins, turnips, eggplant, parsnips, black pepper plant, cauliflower, garlic, summer squash, artichokes, and zucchini are other container-friendly plants.
Best Flowers for Containers
We are all used to seeing geraniums, pelargoniums, and petunias training abundantly from baskets and window boxes. However, there are many other choices:
- Flowering tobacco
- Dwarf Dahlias
- Dwarf Cannas
- Day Lilies
Easy Fruits to Grow in Pots
A delightful and easy way to enjoy fresh fruit, straight from the patio or balcony is to garden in a pot. Here are some fruits to start with:
- Nectarines and Peaches
You can grow other berries like raspberries and blueberries. These look attractive in pretty tubs/terracotta containers and are good choices to experiment with.
Pineapples are also fun to grow and give an exotic zing to the balcony but they need full sun.
Trellis, stakes, cages, netting, and balcony railing work well for vines and climbing varieties of plants.
Additionally, some plants can be grown together in a large pot, and a tepee of bamboo sticks as support. Experimentation is the key to success.
Even with a large garden, container growing can produce eye-catching displays and a bountiful harvest for the kitchen, all within easy reach of the house.
