When do acorns sprout

They can be separated from any twigs or leaves if you have the time, but it is not essential. Acorns are not dormant, so they need no pretreatment for them to grow. In fact, our main difficulty is stopping them from germinating until we want them to! If they are kept in damp conditions, they will grow very quickly, even without soil. Plant two acorns in a pot filled almost to the top with peat-free compost. Any container will do — a yoghurt pot or root trainer. Make sure there are drainage holes in the bottom, and just cover the acorn with compost about 2cm deep.

Protect the acorns from predation! Mice and jays love them, so cover them over with fine wire mesh to keep them out. If you are sowing outside, sow them in good soil to a depth of 5cm and firm. Aim for a density of about plants in a square metre. This means sowing about acorns. Never let your pots dry out! Stand them in a shady, sheltered spot, out of doors and water, from the top, until the seedlings emerge.

It should sprout in a few weeks. If it does not send a shoot above the soil by June or July, and you live in the North Central Texas area, please contact us for a replacement acorn. The benefits of these trees are for all to enjoy—but only if your acorn grows. Our ability to replace acorns that do not germinate will be based on seasonal availability.

We are hopeful that our local oaks will grow acorns each year to harvest and pass along to others. However, acorn availability in the fall is dependent on the weather conditions during the spring flowering period. Once you contact us, you will be placed on our replacement list and we will mail you an acorn as soon as they are available. If you received a large acorn, it is most likely to be a Bur Oak acorn, Quercus macrocarpa.

When transplanted from the container into the landscape, remember that your new tree needs full sun and will become very large. Because the acorns are so large, you may want to plant it away from pools, driveways, and other areas where the acorns might be a nuisance. If the acorn is less than an inch in diameter, it is likely a Shumard Red Oak acorn, Quercus shumardii.

It too, needs full sun and a large growing area. Some trees can produce large numbers of acorns, so plant the tree in a location where dropping acorns will not be a problematic. Steve Houser.

Seeds for the Future: How to Plant an Acorn Bur Oaks produce large acorns that are easy to gather and plant in containers. Before planting, remove the caps and soak in water over night.

Posted by Mr. About the author. Most oak species produce a good crop of acorns once every two or three years. However, the white oak Quercus alba tends to produce a good acorn crop once every four to six years. Weather and other factors can affect flowering and fruiting. For example, freezing temperatures in spring when trees are flowering can damage or destroy the flowers, drastically reducing the fruit crop.

The acorns of white oak, swamp white oak Quercus bicolor , and bur oak Quercus macrocarpa mature in one year. Red oak Quercus rubra and pin oak Quercus palustris acorns mature in two years. Acorns should be collected as soon as they fall to the ground. Sound, viable acorns can be separated from damaged or unfilled acorns by placing them in water. Sound acorns sink. Most floating acorns are not viable and can be discarded. The acorns of white oak and swamp white oak should be planted in fall.

They will germinate immediately after sowing. Acorns of bur oak , pin oak, and red oak will not germinate until they have been exposed to cool temperatures and moist conditions for several weeks. Winter weather in Iowa normally provides the necessary conditions to break dormancy.
