Warm Season Vegetables

tomatoesapril_pcojenAs their name indicates, this group of vegetables prefers warm weather to develop properly.  How warm?  For most of the plants listed below--it's safe to plant when the nights consistently stay at 50 degrees.  For some in Colorado Springs, that may be as early as mid-May.  At higher elevations, that might mean June 1!

You can fool plants and get a jump on the season by using plant protectors (such as Wall O Waters) that will help warm the soil and air around your plants.  It's especially important to acclimate (harden off) these plants prior to planting.   Remember, they've lived in the nice warm protected greenhouse for the first 6-8 weeks of their lives.   You'll need to get them used to the real world realities of their new home!

Tips for Success: Our growing season is relatively short. To give you the best chance for a healthy harvest, we offer short-season vegetable varieties. For more information about when to plant, see Phelan Gardens vegetable planting guideline.  Hail is a reality in our area.  We offer hail cloth to help protect your plants from unexpected damage.

Rich loose soil is also a must for successful vegetable gardens. Amend each year with bagged compost OR make your own.  See our guide for starting your own compost pile.

Give the vegetables below a spot that receives sun for at least 8 hours, consistent water, fertilizer and warm soil, and you will be on your way to fresh vegetables from your own backyard.


ArtichokeImperial Star is a globe artichoke that has been bred to produce artichokes during the first season. It's hardy to zone 7 so treat it as an annual in Colorado. Give it a sunny spot with room to grow (plants can get 3-4 feet high and wide) Bears nearly spineless buds 3"-4" in size.

Imperial Star--95 days to harvest


beans_pcojenWe offer both bush and pole types. Bush beans typically produce quicker than pole beans but for shorter periods of time. You'll need to plant a new crop every 2 weeks for bush types to produce throughout the season. Pole beans will take longer to produce but once they begin, will continue all season. Whichever you choose, try to water at the base of the plants, leaving the leaves dry. This helps prevent the spread of disease.


Blue Lake Pole--5'-6' vines, sweet fiberless 6" beans, wonderful for canning (60 days)

Kentucky Blue: 6" green pole bean, vigorous vine. (58 days)

Goldmine Bush--A yellow wax bean. 15"-20" tall, 6" sweet yellow beans, (55 days)

corn_pcojencornlr_pcojenThe biggest trick to growing corn is that you need to grow enough plants for proper wind pollination. To achieve this, plant in 'blocks' with a minimum of 4 rows of a single variety of corn. In a typical home gardening setting, cross pollination will occur if you plant two different kinds of corn in the same yard. Apply a fertilizer (with numbers close to 9-5-3) at time of planting, when you have 10" plants, and again when tassels form.


Silver Queen: Hybrid sweet white corn produces 8"-9" ears. 90 days
Sweet Perfection: NEW! Yellow sweet corn with slightly earlier development. 77 days.


cucumber_pcojenCucumbers like it ESPECIALLY warm. Do not plant until at least a WEEK AFTER final frost. Provide ample water but make sure your soil is well drained. Drought will cause deformed fruit. It is very important to acclimate your cucumber starts to Colorado wind prior to planting. While your plants are young, you might even want to place a plant protector around them (Wall O Water) for additional protection and warmth. Cucumbers are like peas in that you need to harvest the fruit to get them to keep producing. If you are short on space, try a bush type which will be a more compact vine (actual fruit can be pickle size or regular slicers).

Vining Type Varieties:
Straight 8 Elite:
6"-8" slicer, improved hybrid of heirloom variety "Straight Eight". (65 days)

Do you prefer sweet or hot? Bells or bananas?  We've got a lot of choices for you.  One thing they've all got in common is that peppers MUST have warm temperatures to produce.  So, don't be in a rush to get these in the ground--follow our 50 degree night rule above or use plant protectors to warm the soil.   You can keep these protectors on while the plants are young.  Fertilize at planting time and again mid-season.  Keep soil consistently moist.   If you are a beginner, the smaller fruited peppers are reliable producers in our short season (ex. banana etc.).
