When planting a container-grown tree, dig a hole that is 2 to 3 times wider than the diameter of the container. The depth of the hole should be 2 or 3 inches less than the height of the soil ball. Slope the sides of the hole so the top

Plant onion plants from early April to early May. Place plants 1 to 1½ inches deep in rows 12 to 15 inches apart. To produce large, dry onions, space plants 2 to 3 inches apart.
Plant onion seeds as soon as the ground can be worked in spring (late March or early April in southern Iowa, early to mid-April in central Iowa, and mid to late April in northern portions of the state). Plant seeds in rows 12 to 15 inches ap
Before planting sets, separate the bulbs into two size groups -- those smaller than a nickel in diameter and those larger than a nickel. The larger sets often bolt (produce a flower stalk) and don’t produce good-sized bulbs. Use the la
When ready to plant, trim off the older leaves, place the roots of the plants in water for an hour, then plant immediately. Set each plant in the ground so the crown of the plant is even with the soil surface.
In March or early April, remove all small, weak canes, leaving only 4 or 5 of the largest, most vigorous canes per clump or plant. Cut back the lateral (side) branches to 12 inches in length.
Early spring is the best time to prune blueberries. In Iowa, late March or early April would be an appropriate time to prune blueberries.
Popular fall-bearing red raspberry varieties include:
Grapevines produce fruit clusters on the previous season’s growth. Before pruning, a grapevine may have 200 to 300 buds capable of producing fruit. If the vine is not pruned, the number of grape clusters would be excessive and the grap
All summer-bearing red raspberries should be pruned in the same manner. Summer-bearing red raspberry varieties include:
There are summer-bearing and fall-bearing yellow raspberry varieties. ‘Honey Queen’ is a summer-bearing variety. Fall-bearing yellow raspberry varieties include ‘Fall Gold,’ ‘Golden Harvest,’ and ‘Anne.’
Honeydew is a sticky, sugar-rich substance produced by insects that suck sap from plant leaves and stems. This excretion often coats lower leaves, tables, and floors and when severe, may promote the growth of black sooty mold.
Materials needed to make hardwood stem cuttings include a pruning shears, rooting hormone, plastic bag, and sphagnum moss or wood shavings. Use the pruning shears to collect cutting material and also cut the shoots to the proper length. 
There are many native woodland wildflowers that are great additions to the shade garden. Most are ephemeral with a relatively short (but impactful) bloom time in early spring before the foliage dies back to the ground in early summer.
While most gardeners prefer to grow perennials from established plants in containers or as divisions, transplants, or bare root, it is possible to grow many perennials successfully from seed. The reason why perennials grown from established
One of the first signs of spring is the emergence of crocuses, daffodils, and other spring-flowering bulbs. Several other perennials also bloom in early spring and complement these familiar bulbs.
If given good care in the home, poinsettias should remain attractive for 2 to 3 months. Toss the poinsettia when you grow tired of it or it becomes unattractive.
Several species of shrubs can help get your spring off to a colorful start. These multi-stemmed woody plants vary in size and often bloom before the leaves emerge in spring.
There are a number of species and varieties of bulbs and bulb-like structures like corms and tubers that grow well in Iowa.
While most deciduous trees have flowers of some kind in springtime, they tend to be small and not showy. There are several species of smaller, ornamental trees that have showy blooms in the spring.
The germination medium should be lightweight, porous, and free of pathogens. Excellent seed-starting media are commercially prepared soilless mixes, such as Jiffy Mix. Use a high quality, well-drained potting mix when transplanting see
For most home gardeners, a plug-in shop fluorescent or LED light fixture is the perfect type of light to use for seed starting. When shopping for fluorescent lights, look for high-output, full-spectrum (some
Garlic is distinguished from its other close family members like onions, chives, shallots, and leeks, by its flat leaves and clove-like bulbs which contain several small scales or cloves enclosed in a white or purplish parchment-like sheath.
Carefully consider possible planting sites as asparagus is a perennial crop. A well maintained asparagus planting may be productive for 15 to 20 years.
Potatoes grow best in well-drained, fertile soils. The planting site should also receive at least six hours of direct sun each day.
Rhubarb performs best in well-drained, fertile soils that are high in organic matter. Heavy, clay soils can often be improved by incorporating organic matter, such as compost or well-rotted manure, into the upper 12 to 15 inches of soil.&nbs
When selecting a planting site, choose an area that receives full sun and has a well-drained soil. Planting sites should receive at least 6 hours of direct sun per day. Leaf and root diseases are often problems in poorly drained, wet s
Vegetables grow best in a well-drained, fertile soil. The garden site should also receive at least 6 hours of direct sun each day. Avoid shady sites near large trees and shrubs. Most vegetable crops will not produce well if they
In Iowa, October is the time to plant garlic cloves 1-1.5 inches deep and 3-5 inches apart in well-drained, fertile soils.
The asparagus foliage can be cut back to the ground after it has been destroyed by cold temperatures in fall. However, it is generally recommended that the dead foliage be allowed to stand over winter. The dead debris will catch and ho
