Pruning wisteria and transplanting euonymus

(Question)

I took your advice about having patience when my wisteria, which looked like a dead nail after the harsh winter. It produced two small blossoms and then a lot of foliage. It was suggested that I give it an energetic pruning in July. Can you elaborate.
Because of upcoming construction work I would like to relocate a well-established euonymus to another location.

I’m so pleased that the wisteria survived!  In response to your earlier question, we provided a link to “How to get wisteria to bloom: a Toronto Master Gardeners Garden Guide“, which provides details about pruning.  The Royal Horticultural Society has a terrific video that you can view on-line: Video guide to pruning wisteria in summer.

Fortunately, euonymus transplants easily.  That being said, transplanting in hot weather (it is early July) could be quite stressful for the plant.  If possible, wait until it goes dormant in the fall – this generally starts with the first hard freeze in the autumn and continues until you find signs of new grown on the plants in the spring.  As long as the ground is not frozen, plants can be transplanted any time during this period.  It is recommended to plan ahead for transplanting, e.g.,.  prune the roots of any shrubs to be transplanted first, as these roots typically extend beyond the volume of soil that can be moved during the transplant — this strategy prevents transplant shock due to loss of roots.  Pruning the roots keeps them growing within a relatively small area.  Plants that are to be moved in the autumn should be root pruned in March; those to be moved in the spring should be root pruned in October. For details, see Clemson Cooperative Extension’s “Transplanting established trees and shrubs“.

If you need to move your euonymus very soon (in the heat of summer), try and lessen the “shock” to the plant as much as possible.  Make sure you water it well the day before transplanting, to ensure it is well-hydrated.  Choose an overcast day or a coolish evening to transplant.  Water the plant right before moving it — soak the root ball so that soil will stick to its roots when you dig it up.  Dig a nice big hole that will accommodate the roots without crowding them and water the hole thoroughly.  Put the plant into the hole and fill it approximately halfway with water, then permit the water to drain out – it settles the soil surrounding the roots.  Fill the hole with soil, and pat the surface around the plant, making sure there are no air pockets.  Finally, water the entire plant.  If you can, protect the transplanted euonymus from direct sunlight for 3-5 days.  For the first two weeks  or so, the plant will need to be watered at least once a day (depending on the weather).
