I read an article by local garden expert Marianne Binetti 3 years ago about taking cuttings from your shrubs and perennials during the third week in July and I've been doing that ever since. In fact I've been prepping to get ready for that week to make things go a little faster for me. Cleaning out the greenhouse and making room for about 50 or so starts. Getting soil in the pots so I don't have to take my precious cutting and planting time to do that. Just little things to speed up the process.
She says the third week of July is a great time to save some money and make new plants from your favorite shrubs and perennials. Dirt cheap gardeners know most plants can be started from stem, root or leaf cuttings, and the secret to making new plants is to just keep cutting, poking the stems into soil and seeing if they "take" or form roots.
She said her lazy gardening method is to poke the pruning crumbs of freshly trimmed lavender, sage, ueonymous and other perennials with stiff stems directly into the moist soil near the mother plant. She pokes a half dozen stems into the ground and maybe one will survive if she remembers to water. You've got nothing to lose and new plants to gain.
Stem cuttings of shrubs are also easy to make and July is the month to take softwood cuttings of abelia, azaleas, camellia, choisya (Mexican Orange) heather, hydrangea, dogwoods, kerria, mock orange, potentilla, weigela, wisteria and any other shrubby plant that you would like to share or disperse around the garden.
Here are the three easy steps to free plants:
1. Choose a shoot of branch that is soft or pliable. It should be flexible enough to bend and not snap which is why these summer cuttings are called "softwood." Look for branches no thicker than a pencil. Snip off the soft and floppy tip growth from your cutting, leaving a stem about six inches long.
2. Next, strip off the lowest leaves and poke the stem into a pot of rooting medium. Easy-to-root shrubs like hydrangea, willow and forsythia will root if you poke them into the moist potting soil that holds your flowering annuals or perennials. As long as the soil is moist, drains freely and is not being blasted by the hot afternoon sun, the cuttings have a chance to form roots. If you're willing to put in a little more effort, fill a pot with equal parts peat moss, sand and Perlite. The peat moss keeps the mix moist while the Perlite and sand allow for free drainage so air can get to the developing new roots. Insert several cuttings into one pot so the lower half is underground and the top half of the cutting, with at least one pair of leaves, is above the soil level. Remove any leaves that will be covered with the soil, and pinch out any flower buds.
Tip: Most cuttings rot and fail due to fungal infections. Use a clean knife when you take the cuttings and make sure your pots are clean as well. Fresh potting soil or a sterile peat moss and Perlite mix helps banish the fungus.
3. Now you need to keep the rootless cuttings from wilting. Store the pot in a shaded place and keep the soil moist. Mist the foliage if it starts to wilt but do this in the morning so you don't have damp leaves overnight. Some gardeners cover the newly stuck cuttings with a plastic bag (poke a few air holes in the plastic for better air circulation). Shrub cuttings taken this summer should have roots and be ready for transplanting into the garden by next spring.
Dirt Cheap Tip: Professionals use a rooting hormone to increase the odds of their rooting success. Dirt cheap gardeners can use the natural power of willow water. Just cut up sections of willow stems (any type of willow from weeping willow to pussy willow) and soak in a small amount of water. Insert your just-cut stems into this water for 24 hours. Then pot them up and water with the remaining willow water. All willows contain salicylic acid, which is a natural rooting hormone - for free.
Some of the plants I've started are:
Lacecap Hydrangea
Lilac Trees
Weigela
Soapwort
Guara
Mallow
Butterfly Bush
Azalea
Red Valerian
The Dinnerplate Dahlia is still trying to make it but I don't think it will. It's about 'teacup' size now.
This Dahlia must have had it's Cheerios . . . look how this stem stretched up above the others.
I laid a stem of Baby's Breath on the Snow In Summer. Looks pretty together, doesn't it?!
This is the bright orange Geranium the lady sold me saying it was pink. It's losing color and looks really pretty now.
I hope my Cleome re seeds. This one is new to me and came up from seed. I want lots now!
Bachelor Button
Begonia
Malva Zebrina still going crazy!
Sedum Autumn Joy
Soapwort
There are still Campanulas, Snapdragons, Dianthus, Asters, Mums, Spanish Lavender, Fuchsias, Dahlias, Begonias, Primula, Petunias, Purple Heart, Geraniums, Roses and Bleeding Heart showing their last blooms of the season.
