As vegetables grow in your garden, they remove important nutrients from the soil that are necessary for development. Adding fertilizer will help replace elements like nitrogen and phosphorus to aid in growth and yield. There are many methods of fertilizing and many types of fertilizers out there so you have a number of options to achieve the desired results.
The two basic categories of fertilizer are organic and conventional (synthetic) fertilizer. Both methods will work but there are some pros and cons to consider for each. The major reason to choose an organic vegetable fertilizer is to build up your soil for the long haul. Organic fertilizers do not result in salt buildup in the soil and run a significantly lower risk of causing fertilizer burn on plants. The main disadvantage is that organic fertilizers often come with a higher price tag, and because they tend to dissipate more quickly once applied, may need to be applied more frequently. A conventional fertilizer, by contrast, may cause salts to build up in soil over time. However, many conventional fertilizers are less expensive than organics and are formulated to be slow-release, meaning one application can feed plants over a much longer time period than an organic fertilizer. As always, it is important to do some product research and read the instructions carefully before use. Consult one of our experts if you have doubts on how to use the product.
Please keep in mind that adding nutrients that are not needed can result in deficiencies of other nutrients and can damage your plants. For this reason, over fertilizing can be worse than not adding enough. The only real way to judge your soil’s needs is to have a soil analysis completed. Locally, the CSU soil lab will do an analysis for a small fee and you can pick up a free testing kit here at Fort Collins Nursery.
Now that you put in the time and effort to plant your garden, don’t forget to give your plants the additional support they need to thrive through the summer. Support structures such as garden stakes, trellises and cages encourage a healthier crop and provide many benefits to the plants like proper air circulation and additional sunlight.

Pumpkins, with their edible flesh and long storage life are a warm season crop. They require a long growing season of nearly 85 days, so it’s best to start them indoors from seed. About a week after the last frost (on average May 15 along the northern Colorado front range), pumpkins can be planted outdoors. But be careful, pumpkins do not like their roots disturbed. We recommend starting them in a natural peat-pot (offered in the garden shop) that can be planted directly in the soil.
Choose an area in your garden or yard that receives plenty of sunlight, and has at least 8 ft. x 8 ft. for pumpkin vines to spread. Soil should be rich with organic matter, but not over-fertilized, which can stunt fruit growth.
Pumpkins will start to develop after blossoms are pollinated, so encourage pollinators to visit your garden with other flowering plants. Also avoid using pesticides in and around your garden, since also harm beneficial insects as well as pests.
To increase the size of giant pumpkins, pick a few nice-sized fruits and cut back the vine just beyond them. This will help all the resources of the plant to be devoted to the growth of those remaining pumpkins.

One of the most popular additions to any vegetable garden is homegrown tomatoes. Nothing beats the taste of a juicy, sweet tomato that has ripened on the vine.
At Fort Collins Nursery, we offer a huge variety of tomato plants and seeds to satisfy your hankering. Our varieties include: Beefsteak, Cherry, Roma, Brandywine, Lemon Boy, and more! Call us at 970-482-1984 for availability.
Tomatoes are tender plants. We recommend using a Season Extender or Hot Kap to protect against cold temperatures. We also offer frost cloth.
Don’t forget to keep tomatoes off the ground with a sturdy tomato cage, garden stake, tomato tower, or even try a Topsy Turvy, and hang them upside down! Whiskey barrels also make excellent containers for indeterminate tomato plants – they’ll just grow and grow!
Did you know tomato plants like salty soils?
Sunflowers are not only an attractive flower, they also have rich history providing edible seed crops. Sunflowers do best when planted directly in the soil, after night temperatures warm to above 50 degrees. As their name suggests, need plenty of sunlight (minimum of 6 hours per day). They will also turn their flower heads to follow the sun from east to west.
For giant sunflowers, make sure to chose an area in the yard near a fence or support structure. Sunflowers tend to become very top-heavy as seeds develop, sometimes pulling themselves over (credit anna). Watering sunflowers deeply but infrequently encourages deep root development (which will also help them stand upright). Sunflowers can also be utilized for shade and structure for other vegetables in the garden.
In order to keep birds and squirrels from helping themselves to sunflower seeds, paper bags, nylon mesh or nets can be placed over the flower heads. The best bet is to plant a few extra for wildlife to enjoy, and you to enjoy watching them.
Sunflowers tend to attract aphids, which will feed on the plant and cause some stunting. Instead of using a pesticide, which can harm beneficial insects such as bees and butterflies, try spraying aphids off with a jet of water.
Soil tests are one of the most essential keys to a successful landscape. Many people add an all-in-one fertilizer every spring, thinking one application and forget about it. This can actually build up nutrients to levels that lead to plants’ decline.
Besides basic at-home test kits available at the nursery, we have the added benefit of Colorado State University’s soil testing lab kits. For a small fee, CSU will run a complete diagnostic for the exact breakdown of your soil’s nutrients and deficiencies.
A complete report is issued, detailing pH, salts, lime, texture, organic matter, nitrogen, phosphorus and other minerals. They also recommend specific steps to take to balance soil.
Bring in your report to Fort Collins Nursery, and we can help fill your soil’s needs!
Late March is a great time to start planting cool season vegetables. Many of the hardy types can be transplanted into the garden 2-4 weeks before the last frost (average of May 15). Cool season crops prefer cool daytime temperatures of 60 to 80 degrees, and down to 40 degrees at night.
The most hardy, such as broccoli, cabbage, kohlrabi, onions, lettuce, peas, radish, spinach and turnips, can withstand a frost.
Semi-Hardy vegetables such as beets, carrots, cauliflower, parsley, parsnips, potatoes and Swiss chard are less tolerant of a frost, and may need some protection.
A good rule of thumb is you can plant pea seeds, potatoes and onions (all available in our Garden Shop) directly in the garden after St. Patrick’s Day. Using mulch, Season Extenders and covering with row covers will also help protect veggies from low temperatures.
Cool-season crops will stop producing when temperatures are high in the summertime, but keep in mind you can plant them again for another round of crops for a fall harvest!
Colorado State University Cooperative Extension offers a great vegetable planting guide and vegetable garden hints.
Our Colorado environment is home to some amazing native shrubs. Not only are these shrubs disease resistant and perfect for our native soil, they attract birds, butterflies and provide year-round interest.
Try adding to your landscape a sumac, Apache plume, serviceberry, rabbitbrush, fernbush, mountain mahogany or buffaloberry.
These shrubs have some very unique features, such as the curly, furry fruit of the mountain mahogony, reddish-orange berries of the buffaloberry or the white clusters of flowers of the serviceberry. After proper placement and establishment, these shrubs require little care.
You won’t find these shrubs outside the southwest region. Adding them to your landscape helps keep the area diversified and encourages the local ecosystem. They can be blended seamlessly with non-native plants, depending on the shrubs water and sun needs.
Ask for a tree and shrub representative to help find these native shrubs to match your landscape needs. We also offer many native trees and perennials, come out and see!

As soon as the soils warms in Spring, it’s a good time to have your lawn aerated. Aeration, which is better for your lawn then thatch raking, will reduce soil compaction and to improve nutrient and moisture delivery.
Lawns will also benefit from more oxygen to the grasses’ root system.
If thatch in your lawn is thicker than ½ inch, core aerate with a mechanical aerator. This will improve the health and vitality of the lawn.
Leave plugs on top and break them up with a mower.
