How hot is 'heat?'
Comments (3)There isn't just a single magic number that will trigger this intolerance.....as in 99% of gardening, it depends :-) Depends on the plant, depends on the time of day it is exposed to heat, the type of heat and even soil moisture content. But that said, there are plants that are considered to be cool season plants or heat intolerant - sweet peas are a classic, ditto pansies. And a fair number of common veggie crops do not do well in hot weather - they bolt or fail to develop properly. These types of plants generally perform best if they are planted early enough so they can mature in mid to late spring before temps rise or in late summer to flourish in the cooler fall temps. Even some plants that are commonly considered for hot weather - like tomatoes - will stop flowering and setting fruit if temperatures exceed a certain point. Temps in the 90's are for sure "hot" :-) The AHS heat zone map rates areas by the number of days the temperature exceeds 82F, if that is any help....See MoreRio Samba
Comments (7)I have a Rio Samba tree rose. I'm in 7a philadelphia. I have had it for only two years but have not had any disease issues so far. I still have two or three beautiful blooms on her, and a few faded ones, which I appreciate given the changing season and cooler weather. She put out a whole bunch of booms once it started to cool down. It may be the last day or so for them, but right now they are wide open and beautiful. I love the color of Rio Samba and don't really mind the fading blooms. The color changes are fine by me. I actually like having several stages of color going at once. She is in a pot right by my door, so I do normally deadhead as I go by, but have stopped since the weather got cooler and she put out the last 10 blooms or so. I suppose the really dead looking blooms are unattractive, but that would be true for any rose, I guess. So, if you like her coloring I would try her. I'd like to have another in bush form to put in the ground, but I am running out of space as it is....See MoreGreen Garlic/Spring Garlic?
Comments (1)Garlic doesn't produce real seed, but hardneck garlics do put up a stalk that has top-sets on it, called bulbils. I plant some bulbils every fall, along with some cloves from mature garlic bulbs, but only to increase my stock. The bulbils will produce very small "rounds" the next summer, not the "spring garlic" you are looking for. So here's what you want to do. To get mature garlic bulbs, plant the garlic cloves in the fall. I plant mine in October, then pile the bed with chopped leaves and cover the whole thing with a layer of pine straw to hold the leaves down in windy weather. Harvest the next June or July when about half of the leaves turn yellow. To get Spring Garlic, plant the cloves (from mature bulbs) in the early spring when you plant lettuce, etc. Add a layer of composted manure (onions and garlic like nitrogen). Harvest when the leaves get big enough to look interesting, but certainly by the time the leaves start to yellow. Eat the bulb, or replant the rounds in the fall for a mature crop. Hope that helps.

Comments (4)A little hard to tell but looks suspiciously like powdery mildew in the later stages of the leaf's infection. Use a diluted milk solution. High moisture levels could be contributing. Also what zone are you in? It's a bit late in the season for northern zones to successfully plant pumpkins....See More- 23 years ago
