Gardening 101: A beginner’s guide to greenhouse gardening

Greenhouses can be an ideal space to grow crops in a contained environment. Whether you’re looking to set up a space to grow crops year-round, or you just want an enclosed space to keep them away from animals, greenhouses can be a good way to accomplish a controlled harvest — so long as you don’t overcrowd, and you don’t bite off more than you can chew (until you’re ready).

What is best to grow in a greenhouse?

To have a good idea of what to grow in a greenhouse, consider: What can beginners grow in a greenhouse? You won’t want to try overwhelming yourself with too many unlike plants if you’re new to the space or gardening, and it may be best to stick with plants you’re familiar with at first. Those are often plants that thrive indoors and ones that you’d typically grow in your garden, like lettuce, tomatoes, cucumbers, peas, and peppers.

Even though the greenhouse will be a contained space, you’ll still need to consider the outdoor conditions when deciding what plants to grow when. You should grow plants that prefer warmer temperatures during the warmer parts of the season and plants that prefer cool temperatures during the cool parts of the season. These will vary depending on what zone you’re in, so be sure to do some research before deciding what to grow first!

Do greenhouses need lighting for plants?

Natural light is always the best way to go for a greenhouse, at least during warmer months when there’s plenty of daylight for the plants to thrive from; however, if your greenhouse is set up to be able to grow plants during the cooler months as well, you may consider other greenhouse lighting requirements such as grow lights. You may need grow lights for a portion of the day in order to provide the plants with the proper amount.

Make sure to do your research for which grow lights are best for the environment you’re in and the plants you’re growing. The wrong kind of light can potentially stunt the growth of the plant, which is the opposite effect you want it to have.

How often should you water greenhouse plants?

Like regular gardening, each plant in the greenhouse will have different watering preferences. You’ll want to treat them similar to your indoor houseplants; they won’t need to be watered every single day. There are plants and vegetables that need their soil to dry out between watering to prevent drowning or rot. It all depends on the climate they originated from. A good rule of thumb for most plants is to wait to water until the first inch or two of the soil is dry.

Make sure when you water, though, that you do so thoroughly. You should water them until it starts to drain from the bottom of the container, then give the soils some time to dry out. It’s also important to keep a regular watering schedule, especially when you’re growing fruits and vegetables. If the soil dries out too much between watering, the production of the vegetables could decrease, and your harvest will be smaller than you had initially imagined.

How big should a greenhouse be?

The key thing to keep in mind when deciding on a greenhouse is that your plants will grow. They’ll grow from starters into sprouts that need to be potted, and possibly outgrow that pot and need a new one. So try not to overestimate when you’re starting out. You’d hate to buy too many seeds and have more plants than you know what to do with.

The recommended minimum size for a greenhouse is 10 feet x 10 feet if you intend to grow a decent amount of plants. However, if you’re looking for something smaller to start out and don’t want to grow too much off the bat, you can always start with one as small as 6 feet x 6 feet. It won’t have a lot of space, but it will house those tomatoes and peppers until you can get a handle on how greenhouse gardening works.

Remember to keep it simple your first time around. You’ll have an easy time adjusting if you work with plants you’re familiar with in an unfamiliar environment instead of attempting to grow unfamiliar plants at the same time. Basic plant care is a must when growing in a greenhouse, so be sure to read up on the ones you intend to get.

3 of the best solar garden lights for a bright and eco-friendly yard

It's important to decorate your garden with stunning flowers and veggies, but it's also vital that your garden be well lit. Whether for parties, late-night harvesting, or quiet nights reading in the warm summer air, solar lights make a fantastic addition to any garden. They can transform a backyard into a cozy after-dinner area, light up a walkway for safe navigation, or bring attention to a favorite tree. Here we'll be going over the essential considerations to keep in mind while shopping for solar garden lights. We'll also include a few of our favorites you might want to add to your landscaping.

What to consider when buying a solar garden light
Not all solar garden lights are created equal; there are a few things you'll want to keep in mind.
Cost
The cost is one of the most important aspects of purchasing a new item for almost everyone. Although solar garden lights are very similar in price, it's still crucial to consider how much you're willing to spend on lights before you go looking. Having a better idea of your budget will help you find the ideal solution.
Ease of install
If you need something easy to put up for a party this weekend, you won't want to buy a setup that'll take hours to put together. Instead, finding a solar light that's easy to install will make life easier and allow you to get back to doing other things like gardening!
Lifespan
Outdoor products never last as long as their indoor cousins, so it's not surprising to find that solar garden lights have a shorter shelf life than other indoor lights. However, this doesn't mean you should have to replace your garden lights every year or bring them in during the winter. Instead, look for a light that can withstand the types of weather you often see and be sure to care for the light properly so it can last a long time.
Aesthetic
Of course, you should like the way your new lights look! If they don't suit the aesthetic of your garden, you'll likely be disappointed and tempted to go looking for other options. So be sure you're looking for a light that's going to suit the rest of your garden, or at least blend in and not take away from your garden ornaments.
