 How to Start Tuberous Begonias in the Greenhouse

Tuberous begonias are one of my favorite summertime flowers. Striking in containers and hanging baskets, if treated right they give color all summer and into fall. These big beauties bloom in many colors and are not to be confused with the smaller wax begonias you will see later in the season sold in pony packs. The showy tuberous begonia makes a big impact.

Since tuberous begonias can be started indoors in early spring, I decided to give my begonias a jump start in my greenhouse – Starting begonias in a greenhouse.

  • Choosing Good Tubers

Right around now, begonia tubers are available at home and garden centers,usually in packages of three tubers that look like this.

Starting out with healthy tubers is very important. While at the garden center, I try to examine the tubers in the package as best I can. I look past the wood chips to determine if the tubers are healthy. I look for plump, firm tubers. If a tuber feels mushy when squeezed, that means it’s starting to rot. I also look for any sign of emerging stems on the concave side of the tuber.

They usually appear at first as tiny red or pink bumps and then they start to bud out. So in this case, red or pink bumps are a good thing as this means the tuber is viable.

 

 

  •  Starting the Tubers in the Greenhouse

I planted the tubers in square 5-inch plastic pots that drain. I used a 50/50 blend of seedling starter mix and regular potting soil and moistened it slightly before filling the containers.

I filled each container with soil until it was about two to three inches short of the top and then placed the tuber in the middle with the root side down and the side with the emerging stems (pink bumps) up. I pushed the tuber down into the soil but didn’t completely submerge it.

Then I covered the tubers with a dusting of soil. I watered around (but not on top of) the tuber to moisten the soil. During the tuber’s time in the greenhouse, it’s important to keep the soil moist but not soggy. And since tubers can rot fairly easily, it’s also important not to have standing water on top of the tuber. So in short, water around it, not on top of it. In addition to evenly moist soil, they need lots of bright light, so my grow light will also come in handy.
Once the stems sprout a bit, I will fill more soil in on top of the tuber so that the roots can better develop. Another option at this point is to replant the tuber deeper into the soil.

 

  • Going Outside

When the danger of frost has passed and evening temperatures stay above 50⁰F, I can replant the begonias into containers or hanging baskets and place them outside in partial shade. They should be kept evenly moist (but not soggy) throughout the summer and fertilized occasionally. I’m looking forward to the show.

Thank you for purchasing your Sunglo greenhouse!

Sunglo Greenhouse Tips

Now that your greenhouse is built here are a few things to help you get started-

• Have a certified electrician connect your electricity for the ventilation system, power panel and other electrical components.
• Once electrical has been connected, set your ventilation thermostat and heating thermostat at your desired temperatures.

  • Example of power panel placement (220V shown): Place the panel in a location where it is least likely to be exposed to water.

• Hook up your lights! They can be hung from the trusses for overhead lighting.

  • Example of light placement: You can drill holes through the roof trusses, place an S-hook through the holes, and hang lights and baskets from the hooks.

• Install your shade cloth if the temperature is hot outside. We suggest purchasing 6+ bungee cords and the same amount of eyelet hooks to install your shade cloth.

  • Example of shade cloth on free-standing model: The wooden foundation is perfect to hold the eyelet hooks. For larger greenhouse you can use a long rope at the corners for easy installation and removal.

• Cleaning your greenhouse-

  • We suggest cleaning the greenhouse twice a year with 1/3 cup of bleach per gallon of warm water. Using a long handled mop scrub the outside and inside of the greenhouse. Environmentally safe cleaning products can be used as well.

• Visit the Sunglo blog for information about saving energy, shade cloths, additional accessories and about greenhouse growing.
• If you haven’t already, we suggest investing in a good greenhouse growing book like “The Greenhouse Expert” By Dr. D.G. Hessayon. This will provide you with information on different plants that thrive in your greenhouse atmosphere and additional information about grow lights, plant nutrients, temperature and moisture control, etc.

Greenhouse Gardening Basics

Greenhouse Gardening – The Basics

A few basic items that we recommend you start off with and some words of encouragement!

 

The time has finally come. After all the hours of researching, sifting through greenhouse blogs and forums, having those off and on feelings about making the decision and debating whether or not you have the time and energy to even use one; You have purchased your own greenhouse! And frankly it should be one of the best decisions you made! Greenhouse’s not only give you a space to grow and overwinter plants but the enrichment gardening brings to people’s lives is incredible. And let’s not down play the fact that you will save a few bucks too! But once you have made it through the pain and hectic-ness of finding your perfect greenhouse, building the foundation, greenhouse assembly and the spendy electrician… where do you start? Greenhouse gardening is not as scary as it looks. The greenhouse itself will do a lot of the work for you. Light, air circulation, heat and controls are provided for you. Sunglo’s packages include lighting, ventilation system (for air circulation), heater, controls, etc. – To make life easier on you. Once these have been electrically hooked up you can focus on the fun stuff!

I am a beginner gardener myself and I started off with a small lean-to greenhouse but had no idea where to start! Luckily I had some help and now can say I have an ity bity tiny amount of experience under my belt!

If you own a Sunglo greenhouse you should either have the built in benches and shelves or purchased your own bench system. Obviously this design depends on the type of plants and amount of plants you intend to grow. But adequate space for pots and thingy majigs will make life easier.

 

Here is a list of items I suggest you purchase to start off-

  1. A large bag of soil – Go with a brand that will feed the plants for 90+ days and is suitable for indoor/outdoor gardening. (If you have good compost in your garden already, a special fine seed starter soil without the nutrients might be best.)

 

  1. Seeds! – Choose 3-5 packets to start with and make sure they are appropriate for the season. I would suggest some flowers and tomatoes. Also, read the back of the packet. Seed packets have a great deal of info on the back and the difference between needing full sun and partial shade etc. may sway your decisions.

 

  1. Plants – You want your greenhouse to feel like a garden, so choose a few pretty, green, grown plants to stick in the corners or pull them from the plants you already own. I like cacti and succulents. They are easy to care for and look great! Don’t forget to grab a few pretty pots to transfer them into. The book “The Greenhouse Expert” by Dr. D.G. Hessayon is very useful and provides detailed information on greenhouse plants. I would pick up this book immediately!

 

  1. Little things – Grab a few seed trays (You know the black trays with 50+ squares), you’ll want a small and a large water can, a few 5 gallon buckets for plant scraps, a small circulation fan (unless you have one from Sunglo already), work gloves (get 2 pairs JIC!), hand trowel (small garden shovel), and take a look through all the goodies in your local nursery or garden store. There are always fun things you can pick up!

 

It really depends on the plants you will be growing to determine what kinds of accessories you will want. Eventually you might want to upgrade your atmospheric controls or install some extra shelving. Greenhouses are so fun and customizable. Follow your heart! And remember you can always change things around. Nothing is permanent.

 

The main things to remember are light, temperature and water. As long as you give your plants adequate light, keep the desired temperature and water your plants to their specific needs you should have no problems! – OK you might run into a few along the way! I won’t lie to you! But those things are for later on. Enjoy your greenhouse! Experiment with different plants and flowers. Find your passion and relax in your own paradise! That is what a greenhouse is all about. Fulfilling your passion and creating your own oasis.
