50 degrees F for tomato seedlings
Comments (6)Tomatoes should be kept above 50 degrees, but there is a trick that can help if they get colder. Say your tomatoes go down to 35 degrees overnight and sit at that temp for 6 hours. The next day, put them in a greenhouse and let them get up above 90 degrees for 6 hours. Each hour above 90 degrees counters an hour spent below 50 degrees. Why is this so? When a tomato gets cold, Rubisco - a chemical vital to plant growth - is deactivated. Letting the plant get above 90 degrees the next day reverses the effect. I use this trick to very good effect in my greenhouse. It allows me to deliberately cold stress my tomato plants and then reverse the effects the next day. So you don't have a greenhouse? Well, you can make do with a plastic tent or even a partially covered aquarium. Don't EVER put seedlings in a fully closed aquarium, the temperature can easily get above 200 degrees in full sun. A gap an inch wide at one end is usually enough to bring the temp down below 120 degrees which is safe for tomatoes. Be sure to water them well, seedlings will consume incredible amounts of water when in direct sun. DarJones...See MoreTemps below 50 degrees and new tall fescue seedlings?
Comments (5)Thanks wilsocn. ...I went out and bought an instant read cooking thermometer for $3.99. Depending on depth & shade/sun, I was getting soil temperatures of 60-65 with one reading of 58. Look to be in good shape....See MoreBring rosemary in at 50 degrees?
Comments (10)The cultivar Arps is said to be hardiest. I have planted these and unnamed varieties without problems. In the worst of winters, you might get some minor die back in zone 7 but they quickly recuperate. My winter MINIMUMS are in the upper teens on average but average minimums are in the mid/upper 20's during the coldest months but it can get down into the single digits on occasion--and they have been completely buried in snow for days on end. As a houseplant, they ALWAYS died on me so now I don't hesitate to plant any Rosemary variety in the ground--especially as they the local deer HATE them and don't do them any damage--ever. If your zone is marginal and you are concerned, then plant in a warm microclimate. You'd be surprised with how much you push gardening zones but exploiting protected areas around your home. Good luck!...See More50 degrees this Saturday?
Comments (10)It was 1 below yesterday morning and when I watched the local news they said the wind chill factor in Mt. Pocono (14 miles from my house)was 23 below. That is obscene!! I am jealous of you Carol. It must be wonderful to be able to think about working in the yard by Saturday. We still have so much ice and snow here it will be many days before I will have the luxury of a good workout in the yard. Fingers crossed for the warm-up that the weathermen predict....See More- 5 years ago
