Hi all first time posting. early last spring i moved 2 rather small rhododendron from the front of the house to the sides of the house. they get good sunlight and i have been watering them for the past year. also this spring i holly tone- acid a little. i have also been watering. Question though i do not see any new growth it looks to be alive but dormant. There is also big buds but they have never opened. pictures are below. plus some leaves are on the yellowish side. Is there anything else i am missing here? btw i live about 20 minutes north of philly pa.
I live in Philadelphia too. Another thing to consider (in addition to too much sun or heat) is the possibility of black walnut trees nearby. These trees are common in Philadelphia neighborhoods. The juglone they put in the soil is known to kill rhododendrons.
Nist - i live about 40 minutes north of philly in jamison pa. i dont think there are any walnut trees around. i was wondering if there was anyway to spur growth like clipping the buds or something?
Rhododendrons are generally slow-growing, long-lived shrubs of cool climates and exposures. Not the right choice for fast growth in a hot planting site. Heating of the root zones by sun exposure particularly detrimental, this is probably the main reason these often cannot be grown in the Deep South (except for certain types of hot climate adapted evergreen azaleas, of course) even when planted in the shade.
actually today one flower started to bloom on the right and on the left it seems to be sprouting new buds. i guess the holly tone help. any other suggestions to push growth?
