Corylus – Pruning, Winter Care and Fertilizing

Corylus Harry Lauder’s Walking Stick, Red Majestic or Fusco

These plants are both slow growing and “specimen” type plants that will need a minimal amount of pruning. Pruning, however, can be very important to the overall look of the plant. Only prune in early spring before the plant leafs out. Crossing, badly formed or damaged branches should be removed back to a main branch. Some Walking Sticks and all Red Majestic and Fusco are grafted on to a root stock of other corylus plants and the root stock do not have the contorted look, so suckers may come up from the base straight and plain, these can and should be removed as soon as possible. The root stock growth will be more vigorous and can crowd out the original plant. The “contorted” look is important to this plant so then pruning and taking more out is better, this will open the plant in summer and make the winter look more dynamic.

By fertilizing young shrubs you can increase both the size and the amount of flowers on the plant. Granular, liquid or stake type fertilizers can be used. Granular types should be worked into the soil around the plant at a rate of 2 pounds or 2 pints per 100 square feet of planting bed. An alternative way is to drill or punch 6″ deep holes at the drip line of the plant. Poured into these holes should be a total of 1/4 pound of fertilizer per foot of height or spread of the shrub (divided up and poured evenly between all of the holes). These holes should not be filled with more than 1/3 of the fertilizer and then they should be top filled with soil. This method of fertilization should only be done once a year, and is best done in late fall after leaf drop, or in early spring before bud break.

Liquid fertilizers (such as Miracle Gro) are mixed with water and applied the same as you would water the plant (see product for specific details). This should be done three or four times per year starting in late April and ending in mid July. Stake type fertilizers can be used following the directions on the package. With any of the above techniques a balanced mix should be used, 20-20-20 or 20-30-20 or 18-24-16. Organic fertilizers, like manure, can also be used with good results. The material should be worked into open soil at a rate of one bushel per one 6′ shrub or 100 sq. ft. of bed area.

These shrubs need little winter care but, should be occasionally checked for rabbit or other damage. If rabbit damage is found you can protect the plant with a fence formed with hardware cloth (looks like chicken wire but with small square holes). The branches of the plant should be tied in towards the center, then a circle of hardware cloth can be placed around the outside. The base of the hardware cloth should be buried in the soil or mulch. This protection should be installed in late November and removed in mid April.
