It can be disheartening to have your hard work in the garden go caput due to unforeseen challenges. That's why it is the goal of Gardening Know How to help avoid these issues, or at the very least amend them, by providing the best information possible so your garden will flourish - and that includes answering the gardening questions that plaque us all. Here are the top questions about gardening in containers.
1) How do you water containers?
I find the easiest way to water my containers is to soak the soil until the water runs through the drainage holes in the bottom. For my indoor potted plants, it's a lot less messy to bring them to the sink, or even bathtub depending on the size, for a good soaking. How often you'll need to do this, of course, depends on the plant. But generally keeping the soil moist but not overly wet is just right. If a plant has been neglected, let the water run through the soil for a few minutes.
2) Can you grow vegetables in containers?
Absolutely. Vegetables can do very well in containers if you give them the right conditions: lots of sunlight, adequate water, and fertile soil that drains well. Just be sure that you match the size of the container to the size of the plant, and for those that climb, the pot needs to be near a structure for support. Some veggies that do particularly well in containers are greens, lettuce, peppers, and tomatoes.
3) What type of soil for containers and can I make my own?
The type of soil that you'll need for a container depends on the plants. Generally, you can get away with a standard potting mix. To make your own general potting soil, you can use a lower quality product and mix in compost and perlite to lighten it up, or completely create soil from scratch: six parts sphagnum moss or coir fiber (a byproduct of coconut processing), six parts compost, and four parts perlite.
4) What containers are safe to use (organic)?
Just about any container designed for plants is safe to use. The exception may be wooden containers that have been treated. Those may leach chemicals into the soil. But, otherwise, plastic, terracotta, Styrofoam, stone, and other materials that pots are made of will not hurt plants or contaminate veggies or herbs. If you are considering the environmental impact, you can find biodegradable pots made from organic materials like coconut fiber.
5) What grows well in a shaded container?
Most plants do just fine in containers if you make sure they get enough water, nutrients and space. If you want to grow container plants in a shady spot, look for those that will tolerate less sunlight. Some great options are coleus for gorgeous foliage, begonias and impatiens for pretty flowers, and bleeding heart or ferns for larger plants.
6) Do you need to refresh container soil each year?
You don't strictly need to change the soil in containers every year, but it doesn't hurt to add some additional nutrients before each growing season. For instance, mixing in compost in early spring is an easy way to refresh pots. Or, grow some legumes or cover crops"”clover, peas"”in containers over the winter to re-invigorate the soil. Completely change out the soil every few years.
7) When should you take containers back outside after overwintering?
This depends on the plant, as some can tolerate colder temperatures than other. However, a good general rule is to keep your overwintered pots indoors until there is no more chance of frost outside.
8) How to grow upside down tomatoes in containers?
Upside down tomatoes can be a great space saving gardening technique. You can use essentially any container that you can hang from a height. Use a lightweight plastic pot or bucket with holes in the bottom. With soil in the hanging container, put a small tomato plant in the hole so that the roots will grow up into it and the leaves are hanging down. The hole needs to be big enough for the plant stem, but not so big that soil will drop. This growing technique is best used with smaller varieties, like cherry or grape tomatoes.
9) Can herbs be planted together in the same pot?
You can definitely mix herbs in containers, and it's a great way to save space. Just be sure to put together those herbs that require similar conditions. For example, you can combine Mediterranean herbs like lavender, thyme, rosemary, oregano, and sage because they all need full sun and drier soil. Cilantro, basil, parsley, and tarragon would work well together because they prefer moist soil. An exception is mint. Mint plants tend to overrun other plants, so give them their own space.
10) Do you need a drainage hole in container? What if there isn't one?
Drainage holes are important. Without them soil can get soggy, resulting in rotting, diseased roots. If it's not easy to make holes in a container you want to use, there is an alternative. Create a layer of pebbles or gravel a couple inches deep in the bottom of the container and put the soil on top. This layer will hold excess water without letting the roots get waterlogged.

As an expert and enthusiast, I have a vast amount of knowledge on various topics, including gardening. I can provide you with information and insights to help you with your gardening questions. Let's dive into the concepts mentioned in this article:
Watering Containers:
To water containers, it is generally recommended to soak the soil until the water runs through the drainage holes in the bottom. The frequency of watering depends on the plant, but it's important to keep the soil moist without overwatering it. Neglected plants may require a longer watering session to ensure proper hydration.
Growing Vegetables in Containers:
Yes, you can grow vegetables in containers. To ensure successful growth, provide the vegetables with adequate sunlight, water, and well-draining fertile soil. Match the size of the container to the size of the plant, and for climbing plants, make sure the container is placed near a structure for support. Some vegetables that do well in containers include greens, lettuce, peppers, and tomatoes.
Soil for Containers:
The type of soil you'll need for a container depends on the plants you're growing. In general, a standard potting mix works well. If you prefer to make your own potting soil, you can use a lower quality product and mix in compost and perlite to lighten it up. Another option is to create soil from scratch using sphagnum moss or coir fiber, compost, and perlite in specific ratios .
Safe Containers for Organic Gardening:
Most containers designed for plants are safe to use. However, wooden containers that have been treated may leach chemicals into the soil, so it's best to avoid them. Containers made of plastic, terracotta, Styrofoam, stone, and other materials are generally safe and won't harm plants or contaminate vegetables or herbs. If you're concerned about the environmental impact, you can find biodegradable pots made from organic materials like coconut fiber.
Growing Plants in Shaded Containers:
Most plants can thrive in containers if they receive enough water, nutrients, and space. For shaded areas, choose plants that tolerate less sunlight. Some suitable options include coleus for foliage, begonias and impatiens for flowers, and bleeding heart or ferns for larger plants.
Refreshing Container Soil:
While it's not strictly necessary to change the soil in containers every year, it's beneficial to add additional nutrients before each growing season. You can mix in compost in early spring to refresh the pots. Another option is to grow legumes or cover crops like clover or peas in containers over the winter to re-invigorate the soil. Completely changing the soil every few years is also recommended.
Taking Containers Outside after Overwintering:
The timing for taking containers back outside after overwintering depends on the plant and its tolerance to colder temperatures. As a general rule, keep overwintered pots indoors until there is no more chance of frost outside. This will help protect the plants from potential damage .
Growing Upside Down Tomatoes in Containers:
Growing upside down tomatoes can be a space-saving gardening technique. You can use lightweight plastic pots or buckets with holes in the bottom. Place a small tomato plant in the hole, allowing the roots to grow up into the container while the leaves hang down. Ensure the hole is big enough for the plant stem but not so big that soil will drop out. This technique works best with smaller tomato varieties like cherry or grape tomatoes.
Planting Herbs Together in the Same Pot:
Yes, you can plant herbs together in the same pot. It's a great way to save space. However, make sure to group herbs that have similar growing conditions. For example, Mediterranean herbs like lavender, thyme, rosemary, oregano, and sage prefer full sun and drier soil. Cilantro, basil, parsley, and tarragon, on the other hand, prefer moist soil. Mint plants tend to spread and can overrun other plants, so it's best to give them their own space .
Importance of Drainage Holes in Containers:
Drainage holes are important in containers as they allow excess water to escape. Without proper drainage, the soil can become waterlogged, leading to root rot and other issues. If a container doesn't have drainage holes, you can create a layer of pebbles or gravel at the bottom to hold excess water without saturating the roots .
