When To Plant

Early April

This question always plagues Alaska gardeners. Actually all gardeners ask this question no matter where they live. It's too bad we can't be like central and southern Florida where all year is planting time. But even in Florida planting in July and August gets spotty results at best. There is no insurance on the weather. If you want to be certain there won't be a frost you will have to wait until the middle of June. If you are just cautious Memorial Day weekend will do. Remember the greater the risk the greater the reward. The sooner you plant the sooner you harvest, within reason of course.

A hard freeze is classified as 24° F.  According to the National Garden Association you are past the danger of a hard freeze on April 5. That's 80% of the time there won't be a hard freeze after April 5. There is a 50% chance there will be no temperatures lower than 32 F after May 8. There is a 90% chance there will be no temperatures below 32 F on or after May 19. I've lived in Anchorage for 45+ years and I have seen it snow on May 16. That snow hung around for a day or two. In 2017 the week before Memorial Day the lows were in the mid 30s. I had planted summer and winter squash the week before. The week after Memorial Day I planted summer and winter squash again. In 2016 I was harvesting summer squash the second week in June.

April 24

There are some things you can plant as soon as you can work the ground. They won't grow very fast but they will survive most of what the spring weather will throw at them. Plant peas as soon as you are able. Plant potatoes as soon as you can work the ground. If you get some things in the ground early it will give you more time to do the other stuff that needs to be done when there is a crunch on the time you have. I will most always plant cabbage, broccoli, cauliflower, and sprouts by the third week in May. These last four can be direct seeded but you will get crops much sooner if you use transplants.

By the 20th of May all of your seeds should be in the ground, all of mine are. The ground will probably be below 50° yet but they will grow. If you want to be absolutely safe put in your summer squash Memorial Day weekend. I would chance a week earlier and be prepared to replant if necessary. Crops like leaf lettuce and radishes do best in the cool spring weather. But be prepared to plant subsequent crops as you harvest the first plantings. Radishes and leaf lettuce mature in about 30 days.

Seed Packet Back

Anything that needs a soil temperature greater than 60° F to germinate you should start indoors and transplant or you should grow in a season extended environment. Our soil in Anchorage seldom gets to 60°or more unless it's on the south side of a light colored building in the middle of June.

Planting is the time of anticipation and anxiety. I can't wait 'til it comes up. Then there is the other side of the coin, I hope it comes up. You will experience both. Have fun planting.

Don't throw away the seed packet when you are done planting. The back of the packet has a lot of useful information for later use.
