Is there a rule of thumb regarding the amount of lead time a cold greenhouse gives you for starting or transplanting plants? For instance, if May 1st is my last frost date for outside planting, can I plant/transfer plants two weeks, three weeks, etc. into the greenhouse before May 1st? Continue reading
TWO of my favorite tomatoes for the greenhouse:
EARLY GOLIATH (from Totally Tomatoes): Most impressive of the season. Big early fruit. Good disease resistance. Good flavor. Best of all it had the vigor to continue on throughout the season!
SUN GOLD (from Johnny’s Selected Seeds): Always a great flavored cherry tomato. High-yielding, heat tolerant but some cracking.

“My husband purchased the Gardener’s Greenhouse from the PBM Group.
We are thrilled as can be with it. This is a good first step into greenhouse gardening. This four by four foot structure took my husband a day to put together and it is everything the company promised. The shelving is sturdy, I can easily access my seed trays, and the optional automatic louver works beautifully. Continue reading

The college I work at inherited a large greenhouse (3,500 s/f) with a concrete floor. Would the most efficient way to utilize space be to build raised beds on top of the concrete with landscape timbers throughout the facility rather than using pots on tables? Continue reading
If you are growing tomatoes in your greenhouse be sure to tap the blossoms every morning to insure pollination.

I am completing a 18X24 greenhouse/place to relax and I live at 7,000 ft elevation in NM. I want to know your choise if you could only grow 1 tomato and 1 cucumber plant. Also, if I buy a high pressure sodium light to produce more fruiting, where do you put it when you have climbing plants? Does it have to be moved up as the plants grow? Continue reading
Have you checked your vents for leaks? It is time to be sure that your greenhouse is tightly sealed from cold air. Just a few small air leaks can drop the temperature of your greenhouse immensely. Look into applying weather-stripping to all vents and doors. I prefer the more compressible (and cheaper) foam tape, because it allows for the vents and doors Continue reading
It was not scientific but I was convinced that this is a great way to go for increased late season yields and increased disease resistance. It is especially helpful in growing heirloom varieties that have little in the way of disease resistance.
I was pleased that Continue reading
Look at what I grew from March to early October in my unheated backyard Wyoming greenhouse!
Like many greenhouse growers I live in a short season area where growing tomatoes outside results in poor yields. The best option is to grow indeterminate tomatoes up strings vertically in the greenhouse. I get bushels of fruit every year. One tip I have found is to use fish based fertilizer early in the season. This has resulted in a dramatic reduction in diseases. Later in the season I switch to more balance fertilizers.
