Newly planted tomato plants, marigolds and the frost?

My newly planted spring annuals were subjected to frost last night. Today they are black, do I have to pull them up and start all over or will they survive?

The marigolds may survive and petunias and portulaca will probably survive but those are probably the hardiest of the annuals. Your tomatoes will probably not make it but I would wait to see before I pulled them up.
Reply:The tomatos are history. They have those wall-o-water things you can use if you plant in May and there's still a danger of frost. Personally, I start my tomatos inside around the beginning of April and keep them inside until the last week of May or first week of June before putting them in the ground. The great thing about tomatos is they do well in pots.



I'm not sure about marigolds.
Reply:You do not state what planting zone you are in. That is key to any planting you want to do!

The tomatoes are done. They went into the ground a month to a month and a half to early!! The annuals may make it. The Marigold is generally hardy despite freeze and frost. Hand pick the dead leaves, buds, and discolored vegetation from all the annual plants now. You should be doing this weekly anyway.

I'll post this and hear all kinds of heat. From Planting Zone 4 and above never plant any Vegetable Plant until Mother's Day. A weekend beyond is better. Your local County Extension Agent will give you your zone, and, the last frost date for free (see County Extension Agent OnLine or Phone Book).

Sorry but you lost the plants to spring fever! Good Luck.
Reply:Once tomatoes freeze they are history, you will need to replant. Some of the flowers may live. Marigolds are kind of hearty, if it froze hard they should be pulled up too. I wait until May for Tomatoes.
Reply:Start afresh and protect against frost, or just wait a while longer.
Reply:Probably dead, both of these are not frost tolerant. Look at your local average last frost date, and always plant after that date, you usually can just cover your plants with leaves or mulch or milk cartons, that will protect them, just take it off the next day so they don't overheat.
