I have propagated a cutting and want to know when to plant in ground. Instructions were to root the cutting in early fall. I have some roots, but it is middle of Sept. . . with frost coming soon. Do I put the rooted cutting in the ground before the frost, or keep it indoors all winter in a pot? Please advise.
I would simply pot it up and overwinter it indoors until spring.

What's the name of the shrub pictured on the top of this page? https://www.gardeningknowhow.com/ornamental/shrubs/shgen/variegated-shrubs.htm
I have sprayed my lacecap hydrangeas with well known pesticide but most of the leaves and stems have been decimated. What is causing this and how do I stop it? Regards terry griffiths
I suspect the culprit is slugs, since they do come out at night and disappear during the day. While you would not always see them, if you know for certain they are there or find evidence of their nightly visits, this should confirm the fact that they are munching on your shrub.

If it's not slugs, it could be due to other insects or a fungus of some sort. In this case, neem oil may help. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
I have read your article and done every thing you mentioned: pruned at the right time, added fertiliser and bone meal when I moved it this year, due to re-landscaping. (it's a lacecap species). It used to be in a pot and bloomed well, but I decided to plant it in the ground a few years ago and the first year it bloomed. It is now in its second year of not blooming. The leaves look lovely and healthy. What am I doing wrong? I have read used coffee granules will do the trick. Is that true? Your help will be much appreciated.
Have you had the soil tested? This would help provide insight into what, if anything, is missing in your soil as well as the current pH (hydrangeas are acid lovers, so coffee grounds mixed in the soil won't hurt).
We have a lace cap which hasn't flowered and something seems to be eating at the stem which is putting holes in the stems. Would you have any idea what is causing this, please?
It could be any number of different pests, (slugs, snails or earwigs). I had a problem myself this year, so for me personally, I made a batch of sugar water, (2 cups boiling water to 1/4 cup sugar), let it cool, put it in small containers, (cat food cans work great),and sat the cans next to all my plants, even in my vegetable garden. No more bugs.
I bought a lacecap hydrangea that was labeled blue in color. Trouble is that when it bloomed it was white! Can a white lacecap be turned blue with aluminum or sulphur? Thanks.
White Hydrangea cannot be changed to pink or blue by the grower.
A White will sometimes add some tinges of pink as the plant ages.
It is not unusual for a plant to be miss labeled in the greenhouse.
Will putting potted hydrangeas in a unheated garage be effective so they will come new next year? One "bobo", one lace cap and two that bloom pink flowers and have dark green leaves,(not sure which variety it is).
It really depends on what your zone and what the hardiness of the plants are. Putting a plant in an unheated garage is the same as keeping it one zone above your own zone. So if you live in Zone 5 and you store the hydrangea in the garage, it would be like leaving it outside in Zone 6. The hydrangea will survive fine if it is able to survive Zone 6 or higher.
