In this week’s edition of “Gardentalk,” a heads-up about harvesting the first, early crop of spinach, arugula, mustard greens and radishes. Master Gardener Ed Buyarski said those cool weather plants may be early this season and could start bolting soon with the longer daylight hours.
Buyarski also recommends gardeners start harvesting their kale and spinach that was planted late last summer and left in the ground over the winter.
And don’t forget to feed your other vegetable plants.
For garden vegetables, he recommends a balanced, commercial liquid fertilizer, like 4-4-4 or 4-6-2 with a little more phosphorous. Leafy greens may prefer more nitrogen than root crops, which is reflected in the higher first number.
If you use a granular fertilizer instead of a liquid, apply it just before it rains or before you water your garden.
“You should be watering it in,” Buyarski said.
Buyarski said he’s already harvested some green garlic. He’s looking forward to harvesting scapes in the next few weeks.
A garlic scape will have a small, bulbous form that will grow about midway up (see picture right above) as it begins to curl or loop on itself. Each scape can be pinched off and made into a spicy pesto or chimichurri, and Buyarski said harvesting the scape will also allow the garlic to devote more energy to bulb growth in July.
