The KILL temperature for tomatoes is 2c. If you expect your night time temperatures to be below 4c, I would cover the tomato plant with plastic, and remove the plastic in the morning. The plastic should not be touching the plant. You can cover the plant umbrella style or tent style (fully enclosed like a mini green house). If for some reason you expect to get a really bad cold snap, I would dig the plant up, taking as much soil as possible, you can place the root ball on a piece of plastic (tarp and wrap the root ball), or on burlap, or in a pot, or in a cardboard box... whatever, then move the plant into the shed/garage/on a covered porch close to the house and keep it there until the temps warm up again. The goal when temperatures drop is too keep the morning dew off the plant, and if possible provide warmth by placing it close to the house, or in a enclosed shed.

Tomato seedlings get up to about 2 inches high, then just fall over and die. Spinach did the same. In tropical Darwin. Tried growing seedlings in trays first, plant them out only to loose them about a week later. Trying to Grow in a raised bed as no success into garden soil. Raised bed built mostly of potting mixtures with bags of compost and sand added. Lots of Dynamic lifter, turned over and left fallow for the wet season. Seedlings did the same death rate in the raised bed. What am I missing. Been here for 3 years and first season crops were really abundant. Now everything dies except for my Lime, Lemon and Guava Trees. Is it just to hot for Tomatoes and spinach now?

Tropical climate - plant tomato seeds May, transplant June and July. Your soil mix is very porous, it would dry out very quickly especially in hot Darwin. And with watering it would leach out the fertilisers. With your soil mix you probably needed to water 3-4 times a day. The wet season probably leached all the Dynamic Lifter out of the soil. Ok- potting mix has a lot of wood in it. Material like this grabs the nitrogen before the plant does. Compost would do the same if it is not completely broken down. Here is what I do, sub tropical, in the fallow season Nov to April, I dig/turn my soil over adding grass clippings, shrub trimming etc mulched with the mower. With normal rain it will keep this moist and help break down the grass etc. You can add a little D Lifter. By late April /early May after the wet season you should have some good friable soil (depends what the original soil was like). You could add some more compost if you like and maybe manures, about 3-4 (?)

its really hot and humid in south east florida. too far inland for any sea breezes too. I had great luck with a variety bred by UofF for growing here called Floridade. Another one also bred for south fl climate is Talladega and Amelia. I havent grown them for a few years I think I got the seeds on line at rareseeds.com but not sure. Only getting back into gardening last winter as Ive been on hiatus due to illness.

Move them indoors under a grow light (or in a sunny window) from July through September so they won't burn. Some cultivars are more heat resistant and will survive the zone 10 summer outdoors.

Use shade covers. I set 4x4's . 8' high. 40% white shade cloth. Prune bottom leaves to insure plenty of air flow. You can get a higher shade cloth, for your zone, I would get a 50% white shade cloth. I only use mine for late May, June, July and August. I take them down when I see the temps go below 95 deg. I also mulch to retain water. I do not water the leaves, only at soild level and in early mornings. During the hottest months, I water daily.

I am in Zone 8b and was expecting seedlings from a relative so i didn't start any myself. Now, that plan fell through. It's April 5 and I am buying seeds today. Should I start indoors or directly in the soil today? I would just buy new seedlings but I am going all organic again and organic seedlings are too expensive! thanks
