Things Needed
Hydrangea macrophylla , commonly called hortensia , florist hydrangea or big - leaf hydrangea , is a popular hydrangea species that flower with large , showy , world - shaped flowers during summertime . Hydrangea macrophylla flora are reasonably resistive to pests and diseases , but they require a fairish amount of concern to keep them healthy and bally . Although Hydrangea macrophylla is hardy down to USDA zone 6 ( tolerate temperature as frigid as -5 degrees Fahrenheit ) , the flora requires some protection to come through prolonged deep freeze during winter .
Step 1
Select a planting site for the Hydrangea macrophylla that ’s in full to fond sunlight and that has fertile , moist but well - draining land . obviate planting the hydrangea in tedious locations or where watering is difficult .
Step 2
Dig a hole that ’s the same depth as the nursery container and plant the hydrangea in it . water system it generously to soak the soil now after plant it .
Step 3
Water the hydrangea deep and soundly once every week when rainfall is less than 1 inch . H2O new planted hydrangeas to soak the soil down to and around the roots once each hebdomad during the first spring , summertime and early fall .
Step 4
propagate a 2- to 3 - inch - thick stratum of constituent mulch on the basis around the Hydrangea macrophylla to preserve soil moisture and mastery weeds . Spread the mulch so it cover the entire beginning area .
Step 5
Feed the Hydrangea macrophylla once each year in other leap with a slow - release , granular 10 - 10 - 10 or 20 - 20 - 20 NPK plant food at a charge per unit of 2 pounds per 100 square foot of planting layer . Spread the fertiliser granules evenly over the soil around the plant .
Step 6
Prune the blossom stems from the hydrangea after the blush fade in recent summer . slay weaker shoots by rationalise them back to the al-Qaida of the hydrangea flora , allowing a mixture of sure-enough , blooming growth and new , portly stems to remain intact .
Step 7
Protect the Hydrangea macrophylla in winter by link up the shoot together with soft twine and wrap up them with gunny .
Tip
implant the hydrangea in early leap , after all chance of hoar has passed . castrate the colouration of the hydrangea ’s rosiness by change the dirt pH. Create blue flower by make the soil more acidic ( low pH ) with the addition of branding iron sulphate to the soil . Add lime to the soil to make the soil more alkaline ( high pH ) for pink blooms .
Warning
Do n’t earmark the flora to dry out out because this can make a rapid decline of the industrial plant and even death . Water frequently enough to keep the grime from drying out and keep the soil evenly moistened during spring through early fall .
