Select a spot in the semi shade. A spot in the sun will also do, but in that case reckon with ample watering in the summer months. White Hydrangeas do not thrive in the sun, its flowers turn brown.
Dig a hole two to three times bigger than the pot root ball. Throw ample potting soil or peat in the hole. Take the plant out of its old pot. Revitalize the roots by damaging it in a few spots. This will stimulate re-growth of roots. Take the Hydrangea. If the root ball feels a bit dry, put it in a bucket of water for a few minutes, it will saturate and so have a good start. Fill the hole with soil and press this firmly. After planting, water sufficiently. Repeat watering regularly, certainly closely after planting.
March is the best time to cut back your garden Hydrangea. Below you can read how to do this best. Hydrangeas can be divided into two groups, being flowering on old buds and flowering on new buds. Both require different ways of cutting back.
This group includes, amongst others, the Hydrangea macrophylla. This species flowers on the buds developed the previous year.
• Let the flowers stay on in autumn and winter. They will protect the hydrangea against frost.
• Cut the dead flowers from the branches in March. • When you cut a number of old branches down to the ground, the bush can regenerate.
• If you want to reduce the Hydrangea considerably, you can cut off half the branches one year and the other half the next year. The cut back stems will not bear flowers that year.
• Provide extra protection against late night frost for these species, so the buds will not freeze over.
The Annabelle (Hydrangea arborescens) and the Hydrangea paniculata are included in this group. These flower on the branches formed starting spring, and keep on flowering after being cut back. Hydrangea ‘Forever & Ever’ is the only Hydrangea macrophylla that can also be cut back this way.
You can cut back this Hydrangea early spring.
• You can cut the bush down to fifteen centimeters above the ground, for a nice compact plant.
• Do want the plant to be bigger, only cut off the flowers.
• Cutting back Hydrangea ‘Annabelle’ can always be done a bit more rigorously, resulting in beautiful big flowers
• The plants do not need to be cut back in autumn, because the old flowers protect the plant against frost.
Because a Hydrangea flowers so much, it also needs a lot of fertilizer. For this you can use organic, universal fertilizers. These fertilizers are not only beneficial to Hydrangeas, but can be used for your whole garden.
The best time to move the hydrangea is March/April. In these months Hydrangeas are still at rest and have the time to recover before growing again. Also, in that period there is little chance of damage by frost.
• Dig out the Hydrangea. Allow an ample distance from the plant when digging, it does not matter if the root ball is the same size as the plant.
• Dig a new plant hole, this needs to be twice the size and twice the depth of the root ball.
• Fill the plant hole with soil and fertilizer.
• Do not forget to water the plant immediately after the plant is in its new spot.
Hortensia’s doen het prima in pot, maar na drie jaar komt de kluit klem te zitten. Nu kunt u de hortensia gewoon verplaatsen naar een grotere pot met wat potgrond en meststoffen. Wilt u de oude pot behouden? Dan kunt u de hortensia kleiner maken.
• Haal de hortensia uit de pot.
• Zaag ongeveer een derde van de wortelkluit weg.
• Zet hem terug in zijn oude pot, met potgrond en meststoffen erbij.
• Snoei vervolgens alles weg op 15 centimeter boven de grond.
De meeste hortensiasoorten geven het eerstvolgende jaar geen bloemen. Behalve bij de Annabelle en de Pluimhortensia, die lopen gegarandeerd weer uit met bijbehorende bloemen.
Most important when caring for Hydrangea is probably watering. Hydrangea is derived from the Latin word ‘hydro’, which means water. Best is to water the hydrangea regularly, it will be at its prettiest and grow at its best. If you do forget and skip a turn of watering, the leaves may sag. In that case you will need to water the plant promptly, it will recover swiftly. The flowers however may show some brown discolouring.
