Q. Planting Hydrangea

I recently bought a hydrangea. It’s in a small pot and I would like to either put it in bigger pot or in a nice spot in the garden. Is it safe to do so now? Also, is it possible to take cuttings to propagate?

As long as your last frost has passed, you can plant out potted plants. But, if the temps are now rather high, you may want to wait until fall to plant out.

Propagation by cuttings is best done in the early fall. This article will help you with that: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/hydrangea-propagation.htm

Q. Hydrangea Outside

My hydrangea is in a pot outside. Could I bring it inside, or is it too late to care for?

If you have had a hard frost, the plant is probably already in its dormant state. If this is the case, it would be best to move it to a sheltered location (like a garage or near the side of the house) and let it remain in its dormant state. If you store it somewhere that it will not see rain or snow (like the garage), you need to water it once a month.

If it has not frosted where you live, you can still bring it indoors.

Q. Care of Potted Hydrangea

received a potted Hydrangea as a gift. I have had it a week. Every morning since I got the plant it is wilted. I sprayed it with water and it comes back. I am very disapointed. Can someone please help.

It may need more water. Hydrangea like water. If the soil has been allowed to completely dry out (which often happens at the store), it may be repelling water. I would soak the pot in a sink filled with water for an hour or so to make sure the soil is rehydrated, then make sure to keep the plant watered when the top of the soil feels just barely dry to the touch.

Q. Care of Hydrangea Bushes

I received two hydrangea bushes for my birthday. One has 11-13 blooms, the other has nine blooms. I have had them out on the deck during the day but bring them in at night, especially if it gets too cool. Fortunately, we have had beautiful weather since I received them. No instructions came with them, so I don’t know how much water to give them or whether to leave them sitting in water or empty them before bringing them in the house. The blooms on the larger plant are dying off around the edges.

If you keep them in pots, you will need to treat them like houseplants. Right now, water only when the soil on top is dry. When the temps rise and you leave them outside all the time, you will find you will need to water them daily. The brown edges on the blossoms are from over watering.

Q. Hydrangeas

After 15 years, my hydrangea wasn’t flowering. I dug it up and my neighbor planted it in a pot. Is this okay? What special care should you give a hydrangea in a plastic pot? The soil was Rapid Grow.

Be sure the container is large enough to accommodate the plant and provides adequate drainage. Its care will be similar to those in the garden, with exception to needing additional water.

Q. Transplanting Hydrangea

Can a Hydrangea that was purchased for Easter and has been an inside plant be transplanted outdoors in Zone 5?

Yes, it can be transplanted, but I would put it off until fall if at all possible. However, as long as the plant is properly acclimated beforehand and the temps are not too hot/cold, you can still go ahead and put your hydrangea in the ground now. In other words, if hydrangeas are hardy in your area, they may be planted in the spring after all chance of frost is gone and preferably before the hot conditions of summer arrive. They must also be conditioned to the outdoors gradually. Be sure to place it in a suitable location and give it plenty of water deeply until the plant establishes itself.

Q. Hydrangea

Why are the leaves on my hydrangeas turning black? I recently transplanted a few potted hydrangea plants. They were the type you buy in a smaller pot as a gift. Some are in sunnier parts than others. I see new growth, but the color change in the leaves is really strange.

It could be either black spot or sooty mold. Both are treatable and in most cases, not fatal to the plants. These articles will help:
