Yes! The heat has “officially arrived” in Connecticut and I’m sure you have noticed how your plants react. They may be stressed from lack of watering – or under attack by insects.
For starters, you may have seen more critters eating foliage or even flowers this time of year. My method for dealing with this is watching and looking over my plants as I water them, a daily routine. Inspect first and identify the problem when you are out and about.
Just recently, I spotted an amazing caterpillar on an elderberry plant and it is eating the foliage daily, but you know what? I decided to let him be because it appears he will turn into a beautiful and large silk moth per my research. See my Facebook posts or Instagram feed for photos of him. However, if he tries to move to other containers, he may be a goner. I hope he will stay where he is on this plant. I have been taking photos daily.
I also spotted but holes in my rhubarb plant – this bummed me out more because my rhubarb in my big pot is spectacular. I LOVE the large showy leaves, reaching at least 12″ in size, but an easy method to dealing with the damage, clip them all off cause new growth arises on this plant continually – and so, I did the BIG haircut on it yesterday. I have not been able to “see” the problem insects yet on this plant – so, not sure it is Japanese beetles- out this time of year, or if another culprit. If you can’t find the bug on damaged foliage, try looking at night. It could be a night visitor.
As far as Japanese beetles, they definitely have been on my Canna plants in one spot, ugh. I hate that – I see them and their damage, so I will probably do the same routine as the rhubarb, and not reach for the spray but be patient because they do not stay all summer. Just cut off the damaged leaves and hope for improvement. Try to stay patient.
One day, I spotted woodpecker pecking at the round spiny pods of my Canna plant. He left some large holes in it – and he was either after something in the pods perhaps, or he was just confused. I have a big sunflower right next to it and they were visiting the flower head for the seeds.
Anyhow, my main thing is to try to determine which insect (or animal) it is before proceeding with steps to remove them or deal with them with sprays. This year has been critter month. We have many chipmunks this year – I’ve seen posts by friends on Facebook too of this problem. They even broke down a rock wall at my neighbor’s property, they are everywhere. I found one in our cloths dryer vent – one day, a scratching noise was happening as I was loading, and thought – what is that?! Well, yup – the poor chipmunk somehow made he was down the tube and got trapped. Yuck.
This time of year, especially with the heat on the rise, will encourage more insects. I also believe, the more plants you have, the more visitors you get! Shake the leaves to see if anything falls off, look at the underside of the leaves if you see holes or round specks of foliage damage, and look inside the plants, meaning push the stems or leaves aside and look into the plant’s areas if you have a full container garden with plants with problems. I did this the other day and found two snails. If you have a very badly infested plant in your container, cut it all the way back to the base – many will regrow from the base with new fresh growth. Toss the infected plant parts into the trash.
Another issue is yellowing on my red banana plants – ugh. I have been trying to really narrow this down – was it the new compost I used this season? (which I was told is organically certified), is it a lack of nutrition – when these plants show signs of weakness, you may want to start adding fast release soluble fertilizer weekly – but usually, when I have good soilless mix, a big pot (like this one above), some good compost – I don’t get this yellowing I’ve experienced here in this photo – which is a 5-6 year plant I put out every year. Perhaps it is STRESS of no rainfall – which we have not received much of – note the dry grass everywhere. Or it could be “too much watering” because the compost may have reduced the drainage ability in the soil, so I cut the yellowing leaf off, reduced my watering in this case to every other day, and so far, no more yellowing. But rest assured, I keep investigating these issues – and I’m testing out new products this year which I will share at my container gardening workshops in May of 2017 with my attendees.
See the bit of asparagus poking out of the foliage of this mixed container garden, the other day I found tiny black caterpillars on it – so I just cut those stems off. Haven’t seen them since. This container has repeat ‘plants’ in it. The blue flowering Ceratostigma (Hardy Plumbago) is a perennial and it has been in this pot for 3 years now. Talk about a nice filler. And the Colocasia is also one which I had overwintered and it is getting really full now.
I also noticed some plants in my landscape with a bit of yellow tones and stressed looking – and it can be a sign of struggle due to lack of rainfall. At least, this is my suspicion. Plants and gardening always keeps you challenged, learning and finding solutions. This year’s challenge has been managing insects and learning about new fertilizers.
FOAM PUMP FERTILIZER
For example, there is a new fertilizer on the market that is a foam pump. You just pump and put it on the soil next to the plant, and then water it in. I tried it out on succulents – and the color on my succulents improved within a week. However, I read “stress” can induce color changes in succulents but the timing was too near the application. I think the fertilizer improved the growth on these right away. Notice this photo, even the Jade plant got red edging on the trim of the leaves. The pumps are cool cause they are easy to apply and measure – reminds me of pumps of hair foam styling products! Read the directions always when using fertilizers or insect sprays, and remember to follow them appropriate. Less is more in some cases, overdoing applications can harm your plants.
Again, I will be sharing all the products I’ve tested out this year at next year’s workshop. There are many new items out there – including new organic types. I also show and tell products at the farmers markets each week.
NEW WORKSHOPS ADDED
Speaking of workshops, I just updated my WORKSHOPSCT.com blogsite with a Soil Sprouts class, and I will be sharing this information tonight at the Windsor Locks Farmers’ Market at the town’s public library located on Main Street. The market is held every Tuesday from 4 to 7 pm on the lawn in the back area of the library. I’ve really enjoyed being there the past couple weeks, and will be there again next week too.
For tonight’s market, I will be selling some alpine plants, great for rock gardens, crevices, and may be used to cascade over walls, and in rock garden scenes of unique container gardens. Sedum ‘Coral Carpet’ is one of the plants I will have available – this is great in rock gardens, and they are very drought tolerant – great for this type of weather we are experiencing, and also a beauty in hanging succulent balls – which is a new creation this season. And a new workshop for next year too!
I mentioned drought in the title of this post – because it seems we are experiencing one – the water is low in our rivers, the plants are not getting much natural rainfall, and this can be rough on plants. I’ve been watering my plants in my container gardens daily, sometimes twice, but remember – don’t water log your soils, allow it to breath between watering, and do the finger test if you are unsure. Insert to your knuckle to see if the soil feels moist or dry and observe your plants habits and look for insects, of course.
Enjoy your day everyone!
