To Pinch or Not To Pinch - When is the Question

August 16, 2009 by Rick

The answer is detailed on our web site http://www.floridafriendlyplants.com/ on the Successful Gardening page under Maintenance by the need to do so and the reasons. Recent strong windstorms topple many fast growing soft stemmed plants like Coleus and Persian Shield.

Remove a few at time 

Time to take this coleus growing in partial shade down a bit at a time to stop it from flowering and accentuate it's shape and strength.

Flowering buds for removal

Look for the flower buds which appear at different stages depending on the coleus variety.

A good length to remove

Removing some tall falowering tips

Cup of coffee in one hand and a few pinches in the other.

 

Pinched Finger Paint Coleus

Finger Paint Coleus after a pinch at the right time still looks stunning. Don't wait until it is too tall and starting to fall apart.

Coleus Finger Paint Sports yellow red and painted leaves

Finger Paint is a red and yellow bicolor coleus that sports some all yellow and some all red branches and leaves. You can pinch the variants so you don't end up with all one color.

Pinche Defiance the most popular coleus

Coleus Defiance growing in the full sun looks good after a careful pinch to reduce height and create a fuller stronger plant.

 

These plants respond quickly to frequent pinching. If you remove the tender tips you will see new shoots develop from the sides of the stems below the pinch point. How much you pinch really depends on how fast the plant is growing and what the desired ultimate height is. Often you just don't know where you want the plant height to end up. A better rule is to pinch regularly and get a feel for how fast it is growing between pinches. If you don't pinch at all the plant may split open or fall over  under the wet conditions we have been having this summer. This is especially true if it is an aggressive grower like coleus or the Persian Shield pictured below.

Time to pinch Persian Shield

Pinching and pruning are tasks that are learned by doing them. Once you get the feel for how plants respond you will have some knowledge that you can carry with you for a better gardening experience and something worth sharing with another generation of gardeners.

pinch Pentas seed heads

Once the butterflies have pollinated all the individual florets, the florets fall off just leaving seed capsules exposed. The seed is generally not viable so you might as well pinch the seed clusters off so the plant can develop new nectar rich flowers faster. Italians are known to be the best pinchers.

Interesting timing on this post. Yesterday I spent the morning 'pinching' my coleus. Only I can't bear to throw away all those good cuttings. Coleus root so easily in pots, in soil, or even in water. I have found that if I poke my cuttings into the ground this (time of year especially) it will prolong my enjoyment of coleus right through the winter. What I've pinched and put in the ground over the last week or two will grow into new healthy plants that will last even longer than the mother plant. Now is the time to 'pot up' those cuttings to be planted in another month where my caladiums fade out, too.

The same with persian shield. Don't throw the cuttings away. Make new plants! Simply keep the newly potted up cuttings moist for a couple of weeks and it is that simple.

oops- I just realized some of these tips keep me out of my local Home Depot for more plant purchases... oh well... don't worry... I'm always there spending my money on other things I can't root easily!
Thanks for a great post, Rick... really great tips! Actually your whole website is an invaluable resource for Florida gardeners! Thanks.

I plant my pinchings, too! And I've been doing a lot of that lately.  I plan to have enough red hots potted up that I won't care if freezes take out my bed again this winter.
But don't worry, Rick. I've seen the preview of good things to come at HD, and I know I'll be shopping!
