I just posted about the squash vine borer and a gardening friend, Gene, mentioned that his squash is smaller than in the video in a comment in the earlier post on squash vine borers. I forgot to mention that while the squash is small before they blossom, I keep them covered with row cover which keeps both the SVB and the squash bugs out but once the plants are bigger and blossoms, we have to take the row cover off for the bees to be able to pollinate them-that’s when we should use the foil.
We have 2 nemesis for our summer squash, winter squash and all pumpkins-squash vine borers and squash bugs and they will be here soon if not already here. This post addresses the squash vine borer.
The squash vine borer as seen above has a BLACK AND ORANGE BODY with CLEAR WINGS. If you see a waspy looking bug that is BLACK with ORANGE WINGS, this is NOT the squash vine borer but a tarantula wasp – don’t mess with it as it has a painful bite but usually won’t sting us unless we agitate it and it is harmless to our plants. Take a good look at the picture above so you can identify the squash vine borer.
This video and article, Protecting Your Squash Plants – Vegetable Gardener is from the Vegetable Gardener site (great site) and shows how to protect our squash vines from the squash vine borer.
In addition to using foil and panty hose as shown in the video, I also bury all my stems as they lay down on the soil-main stem and secondaries so the SVB can’t find the stems. Mostly the SVB attacks the BASE of main vine so be sure to protect that part of the squash vine. This use to be an east coast problem but the SVB has finally crossed west of the Rockies. So be on the lookout.
If your plant suddenly wilts even though it has enough water, or if you do see SVB’s around, look for frasse (poop) that looks like sawdust around the base of the stem and that is where the larvae will be-inside the stem eating your plant. You can try to cut vertically (not across) the stem and dig out the larva with a knife, then bury the stem with dirt. Depending on the damage, your plant may or may not survive. Take precautions now to thwart this pest.
I’ve been totally busy teaching classes lately and the last class I taught was the Santa Fe Master Gardener Intern Class on Vegetables. All I can say to the interns is hang in there. Yes there are some difficult classes to get through but there are some great instructional classes as well that are like a breath of fresh air. It wasn’t till I became a Master Gardener that I really blossomed as a gardener. And now I am a rabid gardener! The knowledge you will continue to gain afterwards, the contacts, camaraderie and friendships you will develop will help you grow as well as the plants you will be growing! Hopefully you enjoyed and learned a lot from the Vegetable class. (Yes it was my favorite class when I was an intern!) So for those of you who couldn’t come to class or aren’t in the program but are interested, here are the information sheets. I want to make them available to all.
VEGETABLE GARDENING IN SANTA FE gives an overview of vegetable gardening in Santa Fe.
INFORMATION SHEET covers what the differences are between an Heirloom, Hybrid and GMO plant and explains what mycorrhizae fungi is and how it helps plants grow.
HERBS is a list of perennial and annual herbs we can grow here in Santa Fe.
PLANTING TOMATOES and PLANTING SQUASH both address how to transplant them into the garden and some of the things I add to help grow these beautiful vegetables and also how to help thwart the dreaded squash vine borer and squash bugs.
SEED STARTING DATE CALCULATOR from Johnny’s Seeds is the same one from the previous post but if you didn’t read it, then here it is. A great tool for when to start seeds or transplant them into the garden.
And now if you will excuse me, I will continue starting my seeds inside! Perfect day-cold, windy and snowy!
Well it’s that time of year-Squash bugs Ughh! You can control squash bugs in your organic garden. Here are some ORGANIC things you can do to deter squash bugs:
-Plant a crop late in the season if possible. Many areas of the country only have one generation of squash bugs and if you plant later you may miss them. If you live in the south where they have 2 generations, read on..
–Cover your plants with row cover to keep them off. This works beautifully but you may have to piece some row covers together to cover some of the larger plants. I use clothes pins to clip them together.
-Use Neem. It is an organic pesticide (and an added benefit is a fungicide). It must be sprayed very early before the bees come out or at dusk when they aren’t around as it won’t hurt them if it is not a direct hit as they only visit the flowers and it is a contact spray. I think it mostly helps deter the squash bug.
-Inspection, hand picking and kill the little buggars. (now you know how strongly I feel about them) By far the most labor intensive but very effective. I hate to handle squash bugs (or any bug-I’m squeamish) so I use gloves, a bucket of soapy water (it drowns them) and inspect each leaf underneath to look for nymphs, eggs, or adults. The adults I throw in the soapy water and if a leaf is really loaded with nymphs, I cut it off and throw it in the soapy water otherwise I just squish them. For the eggs (they are a cluster of rust colored eggs attached to the underneath side of the leaves) I usually just tear off or cut out that portion of the leaf (it won’t hurt it) and throw them into the soapy water. The key to keeping it under control, is to catch them before they multiply too much. I looked up the life cycle online of the squash but and it goes from egg to nymph in 7-10 days so if you get out there every 7 days you will catch them before they get out of control and multiply. Most people wait too late. Get out there and look at your plants!
-Companion planting. I think it was in ‘Organic Gardening Magazine that I read under ‘letter to the editors’, that a lady wrote in to say that you could deter squash bugs on pumpkins, winter squash, summer squash and marrows with diluted/strained onion juice. Evidently just grind one or two up, put it in gallon of water and strain the onions out so your sprayer doesn’t clog. Well she went on to write that doing that was too much work and she plants onions bulbs with her squash every year and hasn’t seen a squash bug since. Well I did the same for my summer squashes, but not for my winter squashes. There have been no squash bugs on the summer squash but I found one on the marrow which means there will be more. I told one of friends that owns a garden nursery about the onions and he said it was too late to plant onions but he was going to throw some chopped onions out in his patch. I’m doing the same today for the marrow and winter squash and will let you know what happens! It can’t hurt and maybe it’ll work!
