Hydrangea Health

Hydrangea

Hydrangeas are lovely plants. There is one for every situation – for shade, for sun, tall, short, giant flowers (mopheads) or more sedate lacy ones (lacecaps). There are some that grow to the size of small trees, some whose blossoms can change color based on the pH of the soil, and others that stay the same. They evoke an old fashioned feel, both in the ground and as cut flowers, either fresh or dried. No wonder people love them.

As much as people love them, though, they are also confused by them. Different types of Hydrangeas require different pruning times, and when you prune has a huge impact on whether or not you get blossoms the next year. And their stems often look quite dead in winter, when, in fact, they aren’t.

Luckily, there is help out there. I am attaching a wonderful brochure put out by Proven Winners which will guide you through the confusion. Below that will be a link so that you can download it for yourself, if you like. I am also attaching a link to a great Hydrangea pruning video put out by Fine Gardening. Between the two I think you will find that Hydrangeas are a lot less daunting, and you will be free to enjoy the incredible number of opportunities that are out there. Have fun!

Time to plant bulbs!

mixed spring bulbs

It’s time! Over the next two to three weeks, depending on your climate (I’m assuming Zones 4-6 for the purposes of this post) it is time to plant the bulbs that you have chosen for your garden. For the bigger ones, like Tulips or Daffodils, it makes sense to dig a hole for each one. If you have been really ambitious and have a lot of bulbs to plant, you can buy an auger bit that attaches to your drill and will make the “digging” a pleasure as long as your soil isn’t too rocky. (Just be sure you get one that is a little bit wider than your bulbs.) If you are planting a lot of little ones on one place, then its easier to dig an entire area to the depth needed, place the bulbs, and then carefully fill it in with soil. Digging hundreds of tiny holes will make you crazy. Space the holes at the proper distance apart for that type of bulb (usually stated on the packet). For a more natural look, space them in clumps, and don’t make the spacing as even.

The next question is, “How Deep?” This depends on what kind of bulb that you are talking about, but the general rule of thumb is to plant it 2-3 times deeper than the bulb is tall. So a good sized tulip bulb would be buried about 8 inches deep, whereas a small crocus bulb would be more like 4 inches.

Once you have the hole ready, you may wonder which way is up, especially if there aren’t any root remnants visible. In general, the flat end goes down and the pointy end up, but if you get one that you really aren’t sure about, plant it on its side and let the plant figure it out for itself. Plants are smart that way. (A side note: as a young gardener, I decided that I wanted to plant a row of Peonies. I ordered them through the mail, for some reason, and when they arrived, they were bare root – no soil. All there was to see was what looked like two bunches of worms attached by some fibrous stuff, some red and some white. I had absolutely no clue what to do with them, and after thinking about it for awhile, I planted them with the red “worms” down. I had a 50/50 chance, but had chosen wrongly and so had planted every single one upside down. I am pleased to say, however, that they righted themselves, and now, more than 20 years later, they still bloom every year. So, you see, plants can be very forgiving.)

Once you have set them in their hole, carefully fill it in, and make sure that they are watered a little over the next few weeks. After that, you can forget about them until they show up in the spring and you pat yourself on the back for a job well done. Have fun!

Time to transplant?

IMG_1133

For similar reasons to why it is a good time to plant plants in the fall, it can also be a good time to transplant them. (See the post from Sept 27th for why.) With transplanting, however, the plants aren’t neatly in pots, dying to be planted,  they are already growing in your garden, so you have to give a little more thought as to whether it’s a good idea to disturb them or not.

A decent rule of thumb is to transplant/divide spring blooming plants in the fall, and fall blooming plants in the spring. When a plant is blooming, it has just expended a lot of its energy to make those flowers, and will expend even more in the near future to set seed, so it doesn’t have a lot of spare energy to rebuild itself in a new place. So if you really wish that your Asters were in a different place, make note of it, and do both of you a favor and move them in the spring. But if your Lady’s Mantle has outgrown its space, by all means, cut it up and move it around.

Dividing perennials is an involved subject in itself. Tools needed can range from a simple trowel to an axe or a saw (I’m not kidding!) And it’s always preferable to do a quick Google search on the particular plant that you are about to divide, in case it has any peculiarities. (Baptisia, and other plants with tap roots, for example, do not like being transplanted or divided much at all, so it’s best to know that going in.) But in general, when you divide something, you need to make sure that you have a decent amount of both root and shoot (stems) on each piece that you plan on putting back in the soil. That ensures that there are enough food gathering parts (the leaves) and water gathering parts (the roots) to help get the plant established.

Bloodroot (Sanguinaria canadensis) is an ephemeral, which means that it blooms in the spring but then goes completely dormant in the summer, dying down below the ground. This needs to be divided after flowering, or you’ll never find it again. I recommend putting in some sort of marker once you have transplanted it so you don’t dig it up again by mistake.

Lady’s Mantle (Alchemilla mollis) is the plant with the chartreuse flowers in this picture. This plant flowers in June and can be divided easily in the fall. The Geraniums in the picture (the magenta and purplish-blue ones) can also be divided in fall.

This is one of the tall Sedums – ‘Neon’, maybe? Sedums flower in the fall so would be something to transplant and divide in the Spring. They take to division really well, although I’d recommend a nice sharp horticultural knife or spade to help you along, unless you have very strong hands!
anemone
Japanese Anemones don’t really like being divided much, and don’t really need it more than once every 10 years or so. When you do, do it in the early spring, when the first leaves start to emerge, so that the plant can have a good long time to recover.

 

As with any new introduction to the ground, an important thing is to water, water, water! As plants go into winter, they need a good store of moisture in their cells to help them survive. Transplanting and dividing on a rainy day is a great start.

So if you’re in a “tidying up” frame of mind, and want to move some things around, the next week or so is a great time to do it for certain plants. (It’s no coincidence that I send these blog entries out just before the weekend… 🙂  )

Montauk Daisy

IMG_1030

The Montauk Daisy is a plant with the rather regal mouthful of a botanical name, Nipponanthemum nipponicum. As botanical the name suggests, it is native to Japan, but it has done so well in places like Long Island, NY, that its common name is a lot more close to home.

The first time I saw a Montauk Daisy, I couldn’t figure out what I was looking at. First of all, it was October, when most of the plants like Shasta Daisies are about finished flowering. Secondly, the plant was huge, almost 4 feet tall and wide, and the flowers were bigger than your typical Shasta. On closer inspection, I could see that the leaves were  leathery and glossy, nothing like any other daisy that I knew. What was this thing?

Eventually someone told me what it was, and I was able to learn more about it. Although it looks like a daisy, it actually isn’t, and is in a genus (Nipponanthemum) all to itself. It doesn’t really act like a daisy, either, since it is more shrub-like than anything else, given its size and shape. If you have the room, though, it’s well worth having in the garden, as it is deer and rabbit resistant as well as being drought and salt tolerant. So if you live on the water or like a beach-themed garden and, like many of us, have deer around, this plant is for you. Provide it with well drained soil, and full sun, and prune it in summer (see blog post from July 12 on how to best do this) and you will get a really pleasant surprise come fall!
